Installation diagram of wall-mounted gas boilers. How to properly install a gas wall-mounted boiler. Installing a heating boiler in a private house: important rules, installation instructions How to install a floor-standing boiler

Despite the fact that today there is a large number of alternative sources heat, gas equipment is still in demand in this area. Gas boilers are able to supply the room with the necessary heat. Moreover, they can be installed both in an apartment and in a private house. In this article we will look at the requirements for this process, and you will also find out that installing a gas boiler yourself is possible.

If the boiler has a power of up to 150 kW, then it can be installed in any non-residential area of the house, for example, a bathroom, bathroom, kitchen.
Boiler power from 150 kW or more is limited in the choice of location. A place for installation on the ground or first floor is allowed.
If the installation location is a kitchen, then per 1 kW of its power there should be 0.2 m 3.
In case of a gas leak, there must be a device in the room to turn off the gas supply.
After installing the gas boiler, all main components should be provided with sufficient access for maintenance.
As for the walls of the room, they must have a fire resistance level of up to 45 minutes.
There are also requirements for the cross-section of the ventilation grille. Calculations are taken for 1 kW of power 8 cm 2.

Separate requirements also apply to the chimney system:

The diameter of the chimney must correspond to the specified parameter in the boiler data sheet.
The pipe should be 0.5 m higher than the ridge.
The chimney pipe should be no more than 25.
Up to 3 folds are allowed.
There must be special openings for cleaning the chimney.
The diameter of the chimney must be equal to or greater than the chimney opening.

When installing a boiler in the kitchen, it is important to ensure the following conditions:

At a height of no less than 800 mm from the floor.
There must be free space under the boiler.
It is recommended to lay a metal sheet on the floor under the boiler.

Before installing the boiler, you must have the necessary documentation that allows you to do this. In particular, a gas supply project is being created for your apartment or house. These documents are developed by the gas supply organization. In the course of obtaining this documentation, you may be required to provide a package of documents that includes the fact that you are the owner of this living space.

The floor-standing boiler is quite heavy. Therefore, first of all, it is necessary to prepare the surface where the wall-mounted boiler will stand. This includes the following:

The screed is poured onto the floor. The floor should be treated with non-combustible material. Make sure the surface is perfectly flat.
It is also advisable to cover the walls with non-combustible material. Otherwise, it is impossible to move the boiler close to the wall. It will be necessary to maintain a distance of up to 10 cm.

When all preparations are completed, installation of auxiliary equipment is carried out. This includes:

Expansion tank.
Collector.
Hydroarrow.
Boiler, etc.

Installation is much easier when there is a project on which all installation locations are indicated. You mark the walls using it, and then make holes for fastening. Also installed equipment already at this stage it is recommended to connect it to the pipeline going to radiators or to heated floors.

If the boiler is already installed, connecting the equipment to the pipes may be difficult. For this reason, it is better to carry out all this work before installing the boiler.

As for the installation of a floor-standing boiler in the house, first of all you should screw on it the fittings and adapters that connect to the pipeline. Adapters can be of different diameters. For example, if the system has natural circulation, then thick pipes are supplied to the boiler. If forced circulation, then the pipes and, accordingly, adapters will be of small diameter.

Having moved the boiler to the prepared place, it should be connected to the chimney. Next, connect the security group and connect it to the rest of the harness.

If you have ever hung cabinets, shelves and similar items, then installing a wall-mounted boiler will not be difficult for you. The wall must be level and strong. In most cases, boilers in an apartment are mounted on a mounting plate. It should be fixed to the wall at the required height. Depending on the finish of the walls, it may be necessary to attach non-combustible material up to 3 mm thick to it. Also take into account the fact that the boiler should be hung at a distance of at least 20 cm from other equipment.

Modern wall-mounted boilers have a lower connection to the heating and water supply system. Therefore, after fixing the boiler to the wall, the boiler is tied.

Connection to the gas pipeline

After installing the boiler, it is also necessary to connect the gas pipeline. This stage of work should be done carefully, because you shouldn’t “joke” with gas. The connection includes the installation of a filter and a valve, which can be used to shut off the gas supply if necessary. Next, connect a special gas hose. But under no circumstances should you install a rubber hose. After a while it will crack. Paronite gaskets are used to seal the threads. After tightening the hose nut, be sure to check it for gas leakage.

So, we have reviewed with you the basic rules for installing a floor-standing and wall-mounted gas boiler. You can share your experience about the work done in the comments to this article. You can also look at the installation diagrams in the corresponding section.

Video

In this video, you will learn about the intricacies of installing a wall-mounted and floor-standing boiler:

Installing a wall-mounted gas boiler involves several logical steps. At the first stage, the purchase and delivery of the boiler is carried out, the purchase required material Tools are needed for installation and assembly.

Material for installing a wall-mounted gas boiler

Installation of a wall-mounted gas boiler begins in the store. Of course, this is not the installation itself, but preparation for it. When purchasing or ordering a wall-mounted gas boiler, you need to find out or inspect whether the boiler is equipped with fastening elements. Usually these are hooks and power dowels. If this fastener is not included with the boiler, it must be purchased.

It is worth noting that “reputable” boiler manufacturers complete the boiler with special installation patterns, which are used to mark and drill holes for mounting the boiler.

Note: Let me remind you that when choosing a wall-mounted gas boiler and purchasing it, you must inquire and request a certificate of conformity for the selected boiler model. Without this certificate, legalization (obtaining permission to connect) will be very problematic.

Tool for installing a gas wall-mounted boiler

For work you need to prepare the following tool:

Electric drill or hammer drill. A drill is needed to drill holes for mounting a gas boiler.
Construction level, more than 1 meter long.

Construction level plays important role, in the installation, namely, of a gas boiler, and especially of a condensing gas boiler. Any tilt of the condensing gas boiler will lead to its failure in the shortest possible time. It’s a good idea to replace the building level with a laser level, this will improve the accuracy of installation.

Preparing the wall for installing a gas boiler

The room where the wall-mounted gas boiler will be located must meet a whole list of requirements for the combustion room. Often, wall-mounted gas boilers are placed in the kitchen and the space in the kitchen must be prepared for installation of the boiler.

In addition to ventilation, airing and other rules, Special attention you need to pay attention to the wall on which the boiler will be placed.

The wall for hanging the gas boiler must be strong. The material or structure of the wall must be adapted to install the power fasteners on which the boiler will hang.
If the wall for hanging the boiler is made of plasterboard, then in advance in the frame of the plasterboard structure, it is necessary to provide and lay firmly fixed wooden blocks at the location where the fastener is installed.
If the material of the wall or its finishing is potentially flammable, a non-flammable gasket of 3 mm thick and more sizes boiler by 10-15 cm.
According to standards, a wall-mounted gas boiler should be 40-45 mm away from the wall. Therefore, the gas boiler is not mounted on the wall, but on bars previously fixed to the wall.

Hanging a gas boiler on the wall

Mark the installation level of the gas boiler. Height from the floor from 800 to 1600 mm.
On wooden wall secure non-combustible material (asbestos) and a piece metal sheet(galvanized sheet).
Other types of walls, for aesthetic installation of the boiler, should be covered with ceramic tiles.
If the boiler is not equipped with a special bracket, install bars at the level of the gas boiler mounting to ensure that the boiler is indented from the wall.
Mark the mounting locations for the gas boiler. Usually, the packaging or instructions contain the exact dimensions of the boiler mounting points or an installation template. It is important to maintain the exact horizontal level of the gas boiler.

Important! A condensing gas boiler should hang with a slight slope, “away from you”, that is, the distance from the boiler to the wall at the top should be less than the distance to the wall at the bottom.

Important to remember! Whatever material the heating system in the house (apartment) is made of, the boiler is connected only with metal pipes.

Preparing a gas boiler for hanging

In front of the gas boiler canopy:

The boiler is removed from the package;
The marking plate on the boiler body is checked against the certificate and invoices;
The bracket included in the boiler kit or other selected fasteners is screwed to the installation location on the wall;
All factory plugs on the boiler are removed;
The internal pipe system MUST be washed.
The gas boiler is hung in place.

After hanging, the horizontal position of the boiler is checked and adjustments are made if necessary. All! Hanging, or rather, installation of the wall-mounted gas boiler is complete. The next step is connecting the gas boiler to the system.

You have purchased a new gas boiler for your private home and it’s time to take its place in the furnace room. To do this, you can hire a specialized company or contact the appropriate service. But the cost of installation in this case will significantly hit your wallet, while there is an opportunity to reduce the cost of the process. Yes, some operations can only be performed by licensed organizations, but this is only half the work; the rest can be handled independently. Here we will talk about how to install a gas boiler in a private house from start to finish.

Where to begin?

Since the installation of new gas-using equipment requires compliance with certain rules, it is worth ordering all work that requires a license from the gas service:

Issuance of technical specifications.
Development of project documentation.
Work on connecting to the natural gas pipeline.

You can complete the rest of the steps yourself. First, you need to obtain technical conditions for installing gas equipment from the gas service. Check them out or make a copy and immediately order project documentation from them. When it is ready, it will need to be approved by the gas service. As you might guess, this procedure is a pure formality; after its completion, a team will come to your home and install the gas boiler in terms of its connection to the fuel line, about which a corresponding report will be drawn up.

All that remains for you to do is to complete the piping and connection to the heating system and laying electrical networks. Here you will have the opportunity to save money, either by doing everything yourself or with the help of familiar plumbers. The last stage is the final paperwork.

It's just short description one of the possible algorithms for solving the problem, but in fact, not everything is so simple, because gas boilers must be installed in compliance with regulatory requirements; it would not hurt to become familiar with them at the stage of choosing a heat generator.

Requirements for boiler installation

First of all, it is necessary to take into account all the requirements for the room where the heat source is supposed to be placed. The options are:

kitchen;
a room inside the house, adjacent to one of the external walls and having windows;
premises in the basement or basement;
in the outer annex.

In the kitchen, installation standards allow the installation of a floor-mounted or wall-mounted unit with a heating capacity of up to 60 kW. Equipment with ratings from 60 to 150 kW can be installed in a separate room on any floor, and from 150 to 350 kW - only on the first or ground floor, in the basement or outbuilding. At the same time, it is important to observe the dimensions of a separate room or an attached part; they cannot be smaller than specified in the standards. The minimum standard height of such a room is 2.5 m for any power within the specified limits.

Note. The thermal power values specified in the standards and affecting the installation conditions of the boiler are the total power of all units in the boiler room, including those working for the needs of domestic hot water.

For heat generators with a capacity of up to 150 kW, in accordance with the standards, the smallest volume of the room for installing a gas boiler is 15 m3, in addition, for each kW of water heating equipment, 0.2 m3 is added to this volume. If the total indicator of all units exceeds 150 kW, then the dimensions of the room are not standardized. But there are rules for the installation and safe operation of boilers, according to which it is necessary to maintain technological gaps between the units and the walls of the room; they are adopted for reasons of ease of maintenance and access to all systems in the boiler room. The dimensions of the passages in accordance with the rules are as follows:

From the protruding part of the gas burner device to the wall with front side heat generator - at least 1 m.
If the operating instructions for the unit say that it needs to be serviced from the side or rear, then you will have to maintain a passage width of 1.5 m, but when there is no such entry, but you need to provide access to other equipment or fittings, then it is enough to make the clearance 700 mm. In other cases, installation requirements are stated in the product documents from the manufacturer.
If you plan to install 2 heat sources in the furnace room, then you should not place them opposite each other, since you will have to provide a clearance of at least 2 m between the protruding parts of the burners.
Nothing should be laid through passages at a height lower than 2 m.

For a kitchen where it is allowed to place not very powerful heating equipment (up to 60 kW), there are not the most stringent requirements for the installation of gas boilers. You just need to comply with the volume standard given above, and also ensure air exchange in the amount of 3 times in 1 hour. Additionally, it is necessary to supply supply air for fuel combustion; its consumption for each unit is indicated in technical specifications. This standard applies to all types of boiler houses.

Note. For heat generators with a closed chamber, the installation standards for gas boilers do not force the supply of an air mixture for combustion, since they take air directly from the street through a coaxial chimney, which will be discussed below.

The regulatory documents propose organizing ventilation for the boiler in the kitchen using an exhaust shaft and a supply grille built into the front door. The flow area of this grid is also standardized; its area cannot be less than 0.025 m2. In the same way, you can arrange air exchange in individual combustion chambers. Difficulties with the supply of fresh air may arise in basements or basement floors, it is possible that in order to comply technical specifications You will need to install a special supply fan.

In boiler rooms located on the first, ground floor or in an extension, window openings with a glazing area of at least 0.03 m2 are needed for each cubic meter of room volume. The attached premises also have requirements for fire resistance of walls, a separate foundation and entrance doors. In addition, the extension cannot be built on the front facade of the building, and during construction it is necessary to retreat 1 m horizontally from the nearest window or door.

It should be noted that the requirements for a gas boiler located in wooden house, are identical to the standards for buildings made of other materials, that is, the rules for installing boiler rooms are the same for all buildings.

Installation work for boiler installation

When suitable premises Once selected and the design documentation has been completed for it, you can begin to manually install the heat generator in place. To do this, you will need a connection diagram for a gas boiler in a private house, which must be present in the project. It shows the installation location, the distance to all enclosing structures and the technical requirements for the work.

Often, the installation of floor-standing gas boilers requires the construction of a foundation. In many cases it is not needed, for example, when the room has a high-quality screed and the weight of the unit does not exceed 50 kg. If the weight of the equipment is greater than this value, then you will have to prepare the foundation. To do this, you need to destroy the existing screed, pour a cushion of crushed stone and compact it thoroughly. Then tie a mesh of periodic profile reinforcement with a diameter of 8 to 12 mm, lay it on the finished base and fill it with concrete.

In order to withstand the technology of installing gas boilers, the dimensions of the foundation in plan should be 50 mm larger than the dimensions of the equipment, and in height it should protrude 50-100 mm above the level of the screed. Complete hardening concrete slab will take you at least 2 weeks, this must be taken into account when planning the work.

Next, a fireproof asbestos or metal gasket is placed on top of the foundation and a heat generator is placed on it, adjusting the legs of the unit so as to maintain a clear horizontal line. After this, using the gas boiler installation diagram, it is connected to all engineering networks except for the fuel line. This connection, as mentioned above, is carried out by a licensed organization.

To install a wall-mounted gas boiler in a private house, you need not a foundation, but solid foundation in the form of an external wall that is able to support the weight of the unit. First of all, markings are made on it, showing where the heat generator itself will be suspended and where the chimney pipe will exit. Then, using a hammer drill, drill in this place through hole, into which a metal sleeve is inserted.

There is no particular difficulty in hanging a wall-mounted gas boiler. If the action takes place in the kitchen of an apartment or house, it is necessary to take measures to protect the furniture from debris and then begin the fastening process. Difficulties may arise when installing heavy units, whose power reaches 120 kW; here you cannot do without an assistant.

Note. When a wall-hung boiler is attached to a wall made of flammable material, a special bracket must be made to allow a clearance of 45 mm between the wall surface and the rear panel of the heater. Also, a sheet of non-flammable material should be attached to the wall, acting as a protective screen.

The last thing to do is piping the gas boiler and installing the chimney. Here it is necessary to compactly place taps and other fittings under the body of the heat generator so that everything looks neat and at the same time it is possible to disassemble or change any element. Therefore, when the heating circuit in the house is made of polypropylene pipes, then it is better to use bronze taps and mud pans, and plastic pipes connect via threaded adapters. In this regard, it is somewhat more difficult to install a double-circuit gas boiler, where you will need to lay pipes for hot water supply and correctly connect them to the appropriate pipes.

Requirements for chimneys

In essence, the requirements for the chimneys of floor-standing and wall-mounted gas boilers are identical; the difference may be in the design of the flue itself. It depends on the design of the heat source:

Heat generators with an open combustion chamber take air from the room and exhaust combustion products through a traditional chimney with natural draft.
Units equipped with a closed chamber draw in air from the street forcibly using a fan through a double-walled pipe, which also serves as a flue (coaxial chimney).

A traditional chimney for a gas boiler is installed in the thickness of the wall or suspended from the outside of the building. The cross-section of the outlet pipe from the unit determines the diameter of the entire chimney; it should be the same size, or better yet, 20-50 mm larger. Horizontal section connecting the boiler to the chimney is ideally 1 m long, the maximum permissible length is 2 m.

Below the insertion point, a door is required for cleaning and internal inspection, and the blind end of the vertical pipe is equipped with a condensate drain system. When installing the chimney of a gas boiler, you must remember that it is not allowed to cover the pipe outlet with umbrellas, deflectors, weather vanes, and so on. In accordance with the regulations, only a narrowing nozzle can be installed.

Unlike traditional exhaust ducts for combustion products, it is much easier to install a double-walled chimney for heat generators with a closed chamber. Having done in external wall a hole of the required diameter and having built a metal sleeve into it, a coaxial chimney is installed, which is a horizontal double-walled pipe of a certain length. The only condition that must be met is a slight slope towards the smoke exit. This is done to prevent condensate formed in the air duct from flowing into the boiler.

Conclusion

So, installing and piping the boiler with your own hands is not an easy task, but it is quite feasible. It will take a lot of time and patience to complete all the documentation, but the installation work itself will take a maximum of 3-4 days, or even less. It is important to prepare well and purchase in advance all the missing elements of the strapping scheme, as well as fasteners.

Autonomous heating, organized using equipment using natural or liquefied gas- the most cost-effective option. Most instructions state that installation of gas equipment should only be carried out by certified companies. But here they are a little disingenuous. Connection of equipment is carried out only by specialists of gas companies, and installation and installation of equipment can be done on your own, but after obtaining permission to operate and install gas appliances. This permit is usually issued by the regional office of the gas company that serves the region.

Installing a boiler and heating system on your own will significantly reduce costs, and the quality of work is usually higher, since the owner does everything, slowly, for himself. Of course, installing a boiler and installing heating is not an easy technical task, but if the rules and requirements for installing equipment are strictly followed, it is quite within the capabilities of a person who has certain knowledge and experience in performing installation work.

Installation work to create a heating circuit in a house or apartment begins after all approvals have been completed and the relevant documents have been received. The list of these documents is small, but their preparation takes a lot of time.

Before you begin installing a gas boiler, you must have the following documents:

If you purchased, for example, a Thermona gas boiler, then the documentation package must include the following documents:

You should be careful when purchasing and carefully check the availability of relevant documents. Without them, approval in Gorgaz could become significantly more complicated. You can read about how to legally connect individual heating in an apartment.

The project has been approved, what to do next?

Most consumers who use gas equipment are confident that only certified specialists have the right to install gas equipment. This is one of the deepest misconceptions. Gas service specialists only deal with wiring and connecting gas pipelines. Therefore, the installation of gas or solid fuel heating boilers, water supply connections, connecting the electrical network to the equipment and other installation work do not require special permission.

It is important to know and comply with the requirements of regulatory documents for the arrangement of the boiler room, chimney and boiler room premises. If selected self installation gas boiler creation price heating system will be significantly lower.

Basic requirements for boiler rooms

If you decide to install a gas boiler yourself, then the requirements for the arrangement of the boiler room must be strictly followed. Failure to comply with them is fraught with a fine and additional costs for eliminating violations of the rules. If there is no room for a boiler room, then a boiler with a power of less than 60 kW can be installed in any room of the house, but most often heating boilers are installed in the kitchen, which must meet the requirements. When installing a wall-mounted boiler, the wall must be made of non-combustible material.

Main characteristics and requirements for the room for installing a gas boiler:

The chimney is the most important element of the system

Before starting heating installation, it is necessary to install a chimney for a gas boiler, the quality factor of which determines the safe and efficient operation of the equipment.

Modern boilers are equipped with sensors that automatically turn off the gas if there is poor draft in the chimney.

There are certain rules for arranging chimneys that must be observed. Failure to follow the rules or a malfunction not detected in a timely manner can lead to tragedy.

Regulatory documents define the basic requirements for the chimney:

the diameter of the chimney must correspond to the diameter specified in the instructions;
to create good draft, the upper end of the chimney is placed 0.5 meters above the roof;
are considered the best chimneys made from steel pipes;
the pipe between the boiler and the chimney should not exceed 25 cm;
the number of turns or bends of the chimney is no more than 3.

Installation of a floor-standing boiler

There are certain rules for installing a gas boiler, and when installing the boiler yourself, Gorgaz representatives will be especially picky. In case of non-compliance with any standards, they can impose a fine and force the violations to be eliminated. You just have to remember that self-installation Do-it-yourself floor-standing or wall-mounted gas boiler installation is not a violation.

Many organizations take advantage of people's poor knowledge of regulations. If you place an order with them for the installation of a gas boiler, the price of the work can reach half the cost of the equipment. Therefore, if all the requirements are met, then Gorgaz employees are obliged to connect and start the boiler for the first time.

A floor-standing gas boiler is most often used for big houses with several floors. Already when purchasing a boiler, you need to pay attention and choose a boiler with a direction of outlet pipes that exactly matches the project. For example, Termona gas boilers are available with several options for the location of outlet pipes. A solid base is then prepared, although the boiler can be mounted on a sheet of galvanized steel. This sheet should protrude more than 30 centimeters beyond the dimensions.

It is important for normal operation to level the boiler.

After installing the boiler, the chimney is connected and checked for draft. To increase the service life of the boiler, it is necessary to install a cleaning filter. It is installed in the return line. Before installing a gas boiler, you need to apply pressure. If everything is normal, the boiler and heating circuit are connected, the system is filled with water, the power supply is connected and an application is made to Gorgaz for connection to the gas main.

Connecting a wall-mounted boiler

If not required high power to heat the house, then ideal option is the installation of a wall-mounted gas boiler, the standards are basically the same, although there are minor differences. Boilers of this type are installed on the walls of rooms that meet the standards. The distance between gas appliances is at least 20 cm, and the distance between the wall and the boiler is 30–50 centimeters. It is necessary to provide water supply to power the boiler, and an electrical network.

Before installing the boiler, it is advisable to rinse running water boiler heat exchanger for removal possible contamination and foreign particles. The fastening strips are located at a height of 0.8 - 1.6 m from the floor. The boiler is connected to the gas mains with a metal pipe or a corrugated flexible stainless steel hose. Such adapters are specially designed for connecting gas equipment.

One of the popular heating boilers is the Thermon gas boiler, which is produced by the Czech company Thermona. The company produces floor, wall, condensation and electric boilers various series and models. The range of products is extremely large. The catalog includes gas and electric, solid fuel and condensing boilers.

Features of installing boilers in apartment buildings

To create an autonomous heating system, it is necessary to install a gas boiler in apartment building the requirements for it are almost the same. For standalone systems apartment buildings turbocharged boilers with a closed combustion chamber are selected. References to SNiP, which prohibits the installation of boiler houses in multi-storey buildings, do not stand up to criticism.

SNiP was developed back in the last century. Subject to compliance with the relevant technical requirements to premises for the installation of modern gas equipment, boilers for autonomous heating can be installed. After all, modern insulated combustion chambers of boilers ensure safety and comfort in the home.

If permission has been received to create an autonomous heating system in an apartment building, then rational decision a double-circuit gas boiler will be installed in the apartment to ensure hot water. The apartment was connected to central heating This means that when installing a separate heating system, you will need to disconnect from it and install a closed autonomous system. This means that you will need to install heating radiators, connect them with pipelines, which are connected to the installed boiler.

Before connecting the circuit to the boiler, it is necessary, and without fail, to apply liquid pressure. For new system the pressure should be 2 times the working pressure. In principle, connecting a gas boiler to the heating system does not matter; it is carried out after testing, but connecting to the gas main and starting the boiler can only be carried out by licensed gas service workers.

The first time, after starting the autonomous heating, you need to monitor and make sure that the boiler and its automation are working correctly. When the set coolant temperature is reached, the boiler should automatically turn off. If this does not happen, then it makes no sense to ask why the gas boiler does not turn off. A serious malfunction has occurred. Either the control unit has failed or the sensor is faulty. In this case, you need to call specialists who are qualified to repair gas boilers.

The most popular energy carrier for individual heating is a gas: combustion releases enough heat to efficient work system and it is relatively cheap. There are two options for installing a boiler operating on this fuel: floor-mounted and wall-mounted. The latter is more common because it is suitable for gas devices with a power of up to 42 kW (enough for heating 450 m2), but if required high productivity- they are mounted on the floor. Benefits wall installation are: price, compactness, ergonomics, no need for a separate room. The work is entrusted to specialists or the boiler is installed with your own hands, subject to compliance with certain building codes and mandatory subsequent registration of gas equipment.

The housing contains: gas burner, heat exchanger, expansion tank, circulation pump and control system. This scheme allows the device to work with maximum efficiency without purchasing and installing additional parts. When choosing a wall-mounted gas boiler, its future functions and performance are taken into account (1 kW per 10 m2 of heated area). If it will be used only for heating, then a single-circuit model is sufficient; if there is a need for hot water supply, you should opt for a double-circuit model.

Another difference concerns the method of installing the chimney (for the exit of combustion products) - there are wall-mounted boilers with a closed or open firebox. In the first case, flue gases are removed forcibly, in the second - due to natural draft. Depending on choice the desired option The technology for installing the outlet pipes is radically different. For boilers with a closed combustion chamber, the circuit includes a coaxial chimney: plastic cylinders inserted into each other; oxygen for combustion enters through one of them. Organizing natural draft involves installing a chimney taking into account all the rules (height - at least 1 m from the outlet, diameter - from 15 mm, mandatory insulation), such work is difficult to carry out independently without the proper skills.

Requirements for premises and installation conditions

When choosing the location of a wall-mounted gas boiler, follow these recommendations:

A prepared channel for removing combustion products is installed away from window or door openings.
Minimum room volume - from 7.5 to 15 m3, depending on the boiler power, ceiling height - 2 m, door width - 80 cm, distance to adjacent wall - 10, to floor - 80, to ceiling - 50, to other objects - 20 cm.
Availability of natural light (at least 0.03 m2 of window surface per 1 m3 of space).
Installing a gas analyzer in rooms where people are constantly present.
Free access to gas equipment.
Mounting area: 8 cm2 per 1 kW of boiler power.
Fire resistance of walls - from 0.75 hours.
Room temperature - from +5 to 35 °C, humidity - no higher than 80%.
For safe combustion of gases, an influx of fresh air of at least 30 m3/h is required, and it must come not only from the street, but also from other rooms of the house (that is, the furnace room cannot be completely isolated, a gap or other ventilation must be left in the upper zone).

It is not recommended to install a wall-mounted boiler in the bathroom, and it is prohibited in the kitchen dual-circuit models. According to the manufacturers’ instructions and SNiP II-35-76 “Boiler installations”, gas heating devices with a power of over 150 kW are installed exclusively on the first or basement floor, but they cannot be installed in the basement of apartment buildings. If the walls of the room are made of flammable material, then a non-flammable gasket with a thickness of at least 3 mm is placed between them and the boiler. The surface for future fasteners must be smooth, reliable and durable.

Basic installation steps

The installation technology implies the following sequence:

Preparatory work.
Placement of fasteners and direct installation of the boiler.
Connection to water supply, gas and electrical networks (in that order).
Connection to the chimney.
Filling the system with water, checking, test run.

Preparation for installation

First of all, the gasification project is approved and implemented: gas is supplied, a ball valve, meter and trap are installed (it is strictly forbidden to do these works yourself; only certified specialists have access). Separate wiring is laid for the power supply, with the obligatory inclusion of a voltage stabilizer in the circuit to protect the automation; provision is also made for providing the wall-mounted boiler with grounding. The presence of all required components is checked and the instructions are studied again. Before starting, the gas boiler, mains and radiators are flushed from debris and foreign particles. These actions are relevant both when commissioning a new system and when replacing a heating device.

Mounting and connecting the boiler

The kit includes a special bracket and clamps; please note that the latter are not always suitable for the wall material; sometimes they are purchased separately. The selection of these parts is extremely important when installing a wall-mounted gas boiler; they must withstand a load exceeding the weight of all equipment. The fasteners are placed parallel to the floor, as level as possible, otherwise the automation will fail. The boiler is hung on the wall, the level is checked and only if there are no distortions is it connected to the heating main. It is planned to dismantle the unit and drain the coolant using appropriate shut-off valves.

Connecting communications and chimney

Wall-mounted gas double-circuit boilers are connected directly to the water supply; to protect against debris, a corner strainer is installed in the return of the heating circuit. Before connecting to the pipes, be sure to remove all plugs. Water is tested for hardness; if it exceeds 2.5 mmol/l, a device must be installed to soften it. It’s easier with gas: all the work is carried out by outside specialists, the owner’s task is to ensure free access to the equipment. The design uses a three-core wire with a plug; when connecting, it is important not to confuse phase and zero, otherwise nothing will work.

The chimney is installed above the roof ridge; for wall-mounted gas boilers, the usual cylindrical shape is recommended, the material is metal, preferably stainless steel. The design is as simple as possible: no more than three bends or turns; a hatch is provided in front of the entrance for cleaning soot. The shorter the connecting pipe, the better; the ideal length is up to 25 cm. When natural draft is organized, it is directed upward with a slight slope towards the boiler.

Filling with coolant and checking

The wall-mounted gas boiler is disconnected from the power supply, then the bottom valve opens and the system is slowly filled with water, after reaching 0.8–1.2 bar it closes. Air pockets are unacceptable; excess is removed through vents on the radiators. Leaks and possible fuel leaks are checked and then everything is reconnected to the power supply. It is forbidden to carry out the first launch independently, just as when supplying gas, access is permitted only if you have the appropriate certificate. When first switched on, the elements of the wall-mounted boiler are checked at maximum loads.

Cost of installation services

The process is quite labor-intensive and expensive; installation is cheaper to do it yourself. The services of specialists for installing a wall-mounted double-circuit gas boiler are estimated at an average of 12,000 rubles, and a single-circuit one - 2,000 less. The cost usually includes work on placing fasteners, connecting to the gas main, heating and water supply systems, chimney, testing and startup. Many companies offer their assistance in obtaining permits, but you need to clarify whether this is part of the estimate or paid separately.

How to install a wall-mounted gas boiler ()? Usually hanging is carried out on a mounting strip. The plank is mounted on the wall at the calculated height, on top of a non-combustible facing pad about three millimeters thick. You should leave at least 20 centimeters to other equipment located in the same room.

Usually wall models connection to the circuits is lower. Installation of the piping is done immediately after installing the wall-mounted boiler. The connection to the gas main is carried out by a specialist. In this area, you can only use metal pipes (not propylene, not rubber), as well as paronite gaskets. The connection is rigid.

To install a gas wall-mounted boiler with your own hands, you will need the following materials:

pipes (optimally metal-plastic);
fastening elements;
building level;
non-flammable sheet for laying on the wall;
tools – screwdrivers, drill, keys;
metal strips for hanging the boiler;
threaded couplings;
tow, glue.

The area of the room for installation is at least 4 square meters, the ceiling is at least 2 meters, an opening window is required. The door width is at least 80 centimeters. A pallet is formed from metal strips, and a sheet of metal is installed on it. The width is slightly larger than the base of the boiler.

The side strips are attached to the pallet and fixed to the wall according to preliminary markings. Control the verticality and horizontality of the fastening system using a level. Drill holes for mounting the boiler, hang the stand and the boiler itself.

The next step is connecting to the water supply. Shut off the water, connect the boiler with a threaded coupling to the pipeline, and seal the connection with tow or a special cord. Start connecting from the end. The supply is connected from above, the return - from below. Next is connecting the boiler to the chimney and to the gas supply.

A few points to pay attention to during installation:

no debris should get into the fan compartment (if any);
the chimney pipe should not come into contact with the wall (indentation - two centimeters), height - at least two meters from the floor;
the horizontal section of the chimney is mounted with a slight slope for free drainage of condensate, a condensate collector is placed under the connection;
For volatile automation, you need to allocate your own electrical wiring line.

Video about installing a gas boiler.

Existing norms and regulations require that the installation of a gas boiler, like any other gas equipment, be carried out by certified specialists from enterprises who have a special license for such activities. But the prices for their services are so high that sometimes they amount to almost half of the cost of the device. In the meantime, a certificate is not needed for installation, but only for work carried out on the gas pipeline itself. Doing it yourself is quite acceptable. Moreover, connecting electricity (if your device is volatile) and coolant, plumbing and other work do not require specialized skills and knowledge.

But it must be remembered that the inspection bodies impose special and fairly strict requirements on the premises in which gas boilers are installed.

Failure to comply with such regulations and standards can lead not only to substantial fines. If you carry out the installation incorrectly, the result may be an accident in which people will become victims. Gas is an extremely explosive and flammable substance. Therefore, you must behave with extreme caution, observing all safety standards.

Requirements for the premises for equipment installation

All requirements are specified in special regulatory documents, which must be read before proceeding with the installation of equipment. The basic rules for installing gas boilers regulate the following points:

A single-circuit boiler can be installed in any room of the house, with the exception of the bathroom, living rooms and bathrooms, if its power does not exceed 60 kW.
The installation of double-circuit equipment in kitchens is prohibited. But even when installing a single-circuit device, the standards for the room area change. The volume of the kitchen should be calculated based on 0.2 m³ per 1 kW of boiler power.
If the power of a wall-mounted gas boiler does not exceed 150 kW, it can be installed on any floor of the building. If it is necessary to connect several devices whose total power is in the range from 150 kW to 350 kW, or one device of the same power, only rooms on the first or basement floor of a residential building are allocated for the boiler room.
The boiler room must be provided with free and comfortable access for personnel servicing gas boilers and auxiliary equipment. For unauthorized persons, access should be limited.
The norms and rules for installing gas equipment require the presence of a source of natural light in the room. The window area should be calculated based on the fact that per 1 m³ of boiler room volume there should be 0.03 m² of window opening area;
The room must be provided with ventilation. Moreover, the ventilation grille should be located at the bottom front door or in a wall partition separating the boiler room from the adjacent room. The width of the ventilation duct is calculated based on the fact that per 1 kW of gas boiler power there should be 8 cm² of ventilation grille area;
Before installing wall-mounted gas boilers, the room must be equipped with a gas analyzer and a valve that will automatically shut off the valve supply in the event of an accident or leak;
The premises in which gas boilers are installed must meet the following characteristics:

the height of the ceilings cannot be less than 2.5 m;
the total volume of the room should not be less than 15 m³;
the width of the entrance door must be at least 80 cm;
The fire resistance limit of walls and their coverings must be at least 0.75 hours.

When installing the boiler, all these requirements must be strictly observed.

Installation of a chimney for heating equipment

One of the most important elements safe work wall-mounted gas boilers have a chimney. Its incorrect installation or malfunction not noticed in time has more than once led to tragedy. But the vast majority of modern heating systems are equipped with automatic systems that shut off the gas supply as soon as the draft force in the chimney weakens.

Connecting gas boilers to chimneys also has its own safety rules. To avoid possible problems and troubles, it is wiser to entrust this work to professionals.

Basic requirements for chimney installation:

The diameter of the chimney exhaust pipe cannot be less than that specified in the instructions for the equipment.
The cross-section of the chimney should not be smaller than the cross-section of the flue outlet of wall-mounted boilers.
The chimney outlet must rise above the roof ridge by at least 0.5 m.
For installation of gas boilers, chimneys with cylindrical shape. It is best if the pipe is made of black or of stainless steel, and has a specially designed hole for cleaning;
Modern rules for installing gas equipment prohibit more than three turns and bends in the chimney pipe, and the shoulder connecting the chimney to the main equipment should not exceed 25 cm in length.

When choosing and purchasing the necessary components, you need to remember these requirements.

Features of installing wall-mounted equipment

Before you begin installing the boiler yourself, you need to obtain a number of approvals and permits.

First of all, it is necessary to draw up and sign an agreement on the supply of natural gas to the building. Next, you need to obtain a project for gasification of housing construction and installation of the necessary equipment. All these documents must be drawn up and approved by specialists from the gas supply company.

When choosing a gas boiler, you need to check the equipment of the device, including the necessary fasteners. It is wiser to give preference to those devices that are equipped with everything necessary for installation, so that you do not have to purchase missing parts later.

When purchasing heating equipment, be sure to make sure that it has a certificate. Otherwise, serious complications may arise when you register the boiler. Carefully compare not only the characteristics of the device. Everything that is described in accompanying documents, must also be indicated on inside appliance doors. Serial numbers wall-mounted boilers must match the numbers included in their warranty cards.

Inspect the equipment again after delivery. If you notice defects on it, then it would be wiser to refuse to accept such a device.

Self-installation of wall equipment

Proper installation of wall gas device requires preliminary preparation. Walls for placing wall-mounted boilers must be made of non-combustible materials, such as concrete or brick. If the floors in the house are wooden, then it is necessary to install a heat-resistant cushion made of a special coating. The thickness of such insulation cannot be less than 3 mm, and the equipment itself must be mounted on remote brackets so that the distance between the boiler and the wall is at least 4.5 cm.

To install the boiler you will need following materials and tools:

adjustable gas wrenches and wrenches;
screwdrivers (phillips and flathead);
pliers;
a hammer drill and a set of drills for it (depending on the wall material);
FUM tape;
gas lubricant.

Before starting installation work, it is necessary to thoroughly rinse all internal channels and tubes of the equipment. To do this, you need to remove the shipping plugs and pass water through the device under slight pressure. The fact is that during assembly of the gas boiler, dust and small debris could get into it, which are best removed before proceeding with installation.

To fix a gas boiler on the wall, special mounting strips are usually used, which are mounted at a height of 80-160 cm from the floor. The equipment itself is already hung on them. Be sure to check the correct location of the boiler using building level. Distortions can lead to incorrect operation of the device.

Remember that the heating device must be installed at a distance of at least 20 cm from any electrical appliances and other gas equipment. There should be no source of open flame, radiators, or flammable products or materials in its immediate vicinity. Neglecting safety rules can lead to disastrous consequences.

Installation of wall equipment

To prevent the heat exchanger of a gas boiler from becoming clogged, a filter must be installed on its pipe. Any equipment needs regular cleaning. The most convenient system is one that does not require draining the water. Therefore, on both sides of the filter it is installed shut-off valves, allowing you to service the boiler without any problems.

Next, you need to assemble and connect the chimney to the boiler. Be sure to check for traction, even if such a step is not provided for in the instructions. This does not need to be done if your device belongs to modern flueless boilers. They remove combustion products small fan. Such forced ventilation does not require draft, but you need to check the operation of the fan itself.

On last stage A gas pipeline is connected to the boiler. To carry out this work, it is necessary to seek the help of specialists from the service or gas supply company. The fact is that existing rules allow gas to be supplied to the device only using a special metal pipe through a characteristic outlet (the so-called American pipe). It is better not to perform such installation on your own.

Installation of floor equipment

It has its own characteristics, but no serious problems should arise with their installation. The main difficulty is that such equipment, as a rule, is not only more powerful than its wall-mounted counterparts, but also has significant weight.

A solid base is installed under the floor-standing boiler, since it has significant weight. In this case, it is not at all necessary to pour a concrete screed. Galvanized iron is quite sufficient. The sheet should be slightly wider than the base of the boiler. The largest margin is left on the front side - at least 30 cm.

When the boiler is completely ready for further operation, it is connected to the power supply. If the device is non-volatile, then it must be equipped with an automatic system that prevents overheating.

It must be remembered that only gas service specialists have the right to start supplying gas to the system. They are required to check the quality of the equipment installation and its compliance existing rules and standards. Only after signing the acceptance certificate can the system be opened gas valve.

It is not uncommon that many private houses do not have centralized heating and water supply. For this reason, owners have to resolve such issues themselves. Wall-mounted gas boilers can come to the rescue. How to correctly install a wall-mounted gas boiler with your own hands? How much does it cost to install a gas boiler?

Today they are presented on the market in a huge number and variety of brands. There should be no problems with their choice. However, it is worth deciding how to install the boiler - on our own or with the help of qualified specialists? The last option is not bad, but you will have to spend extra money to pay employees.

The room in which the boiler will be located must have a window for ventilation. The door to the room should open outward. The room must have an area of more than four square meters. The ceiling should be at a level of two meters or more. Concerning doorway, its width must be at least 800 millimeters. A prerequisite for a boiler room is the presence of a working ventilation duct. Often wall-mounted boilers are located in utility rooms, kitchens or pantries.

Another important condition is to cover the wall where the unit will hang with non-flammable materials. This action will eliminate the possibility of a fire that could occur when a spark hits flammable materials. Modern non-flammable products will harmoniously fit into the design of the room without spoiling the interior.

When purchasing a boiler, you need to obtain an official certificate, because in the absence of this documentation, registration of heating equipment will become almost impossible. The certificate will also allow you to connect the equipment to the gas supply system.

When choosing a location for the unit, you need to consider installing a hood for a gas boiler. Old chimneys can be used, but if they are not available, new chimneys will need to be installed. Most often, the combustion product removal system comes complete with the boiler itself.

Compliance with such rules for installing a gas boiler is vital.

Some tips for installing boilers

One of the most important stages when installing gas heating boilers - their connection to the gas supply system. In order for the regulatory authorities to give permission for it, it is necessary to carry out the installation and installation of the gas boiler strictly in accordance with the recommendations and requirements contained in the technical passport. Otherwise, you will have to redo something, if not everything.

When installing a Navien gas boiler » , as well as the installation of the Immergaz gas boiler, it is important to check whether its power corresponds to the power of the entire heating system. When connecting the boiler to an old heating system, it is imperative to clean and flush all the pipes, which will eliminate the possibility of clogging in the near future.

It is necessary to think through the entire installation scheme of a wall-mounted gas boiler in advance. It must provide for water treatment to supply the system. The entrance to the unit must be equipped with a cleaning and metal-collecting magnetic filter.

One of the worst enemies of a gas boiler, and indeed the entire heating system, is corrosion. Therefore, to avoid its occurrence, it is better to install a closed circuit that will prevent air from freely entering the system.

Installation Rules

A wall-mounted gas boiler must be attached to a load-bearing or solid wall.
During installation of the Ariston gas boiler, you need to ensure that the hood and chimney are proportional.
The unit must be easily accessible so that timely maintenance can be carried out and parts can be freely replaced in case of breakdown.
If the boiler is installed inside a cabinet, it is necessary to provide a five-centimeter space above the equipment from the cabinet partition. This free space will make the components in the upper part accessible, so that any maintenance work will be possible.

Boiler installation technology

Before directly installing gas equipment, you need to deal with the chimney opening.

It will be much more convenient to install if you use a special cardboard template. With its help, you can easily and effortlessly make marks for all fasteners and the chimney. When the location for the boiler is finally chosen, you should attach the template to the wall. It must have points of attachment lines and places where the wires will be connected. These important marks should be transferred to the wall with a marker or colored pencil. Then the template can be removed.

The next step is drilling holes for the dowels. To do this, select a drill that has the desired diameter. Each dowel must be selected in accordance with the material and thickness of the wall. After the holes are ready, metal corners are attached to the wall.

Then you need to remove top cover unit. Now you can safely attach equipment to hanging corners on the wall. Before installing brackets, you need to make sure that all chimney fittings have the right sizes exactly according to the instructions, otherwise there will be problems later. The bracket to which the gas boiler is attached must itself be very securely fixed to the wall. This is the most important point.

It is important to remember that depending on the type of wall there are various ways fastenings There are different types of fastening installations, each of which is designed to install a certain type of unit and type of load.

During installation, it is important to ensure that no debris gets inside the fan. The pipe through which combustion products will be removed must be at least two centimeters away from the wall surface.

Boiler installation tools

Before installing a wall-mounted unit, you should obtain in advance:

screwdrivers,
fasteners,
glue,
tow,
wrenches,
drill,
gloves,
threaded coupling,
non-flammable finishing material.

First you need to close the water supply using the valve. After this, you can connect the boiler and pipeline using a threaded coupling. To achieve the tightest fixation, be sure to use tow. The unit must first be connected from the end side. Innings hot water is connected to the upper pipe of the unit, and the return is connected to the lower pipe.

The distribution box of the unit must be connected to the power cable, and a safety contact outlet must be provided from the switch.

Thanks to the cable, power is supplied to a powerful boiler, and therefore each fuse should not exceed three Amperes in power, or the fuse should have a rating lower than the current rating required for high-quality use of the boiler. At the end of this type of work, you need to connect the gas equipment to reliable grounding.

As you can see, installing a gas boiler on your own is quite doable in the shortest possible time without extra costs time, effort and money. You can study the installation of a wall-mounted gas boiler with your own hands in the video in more detail. For example, the most frequent questions have become regarding the installation of the Danko gas boiler, which is gaining popularity.

The cost of installing a gas boiler is much lower than the cost of calling specialists. In addition, the work is carried out quickly, and the skills acquired during installation will be useful in the future.

A gas boiler is a universal device for heating liquid used as a coolant in autonomous systems heating an apartment or private house. Since the boiler uses explosive gas to operate, its connection must ensure maximum safety for the residents of the house. Therefore, the installation of a wall-mounted gas boiler and all work on its connection to the heating and gas mains must be carried out in strict accordance with building codes and regulations.

Is it possible to install the boiler yourself?

Measures for installing a gas heating system always begin with the development of a project that is agreed upon with representatives of local supervisory services. The project indicates all the necessary parameters of the boiler, determines the location of its installation and describes the functioning diagram of the entire system.

Only after approval of the project can a certain part of the installation work be carried out independently.

However, it must be borne in mind that not all manufacturers allow self-installation of their boilers:

Companies Ariston, Bosch, Viessmann and some others oblige buyers to carry out installation only by certified installers;
More loyal suppliers, such as Electrolux, BAXI, Ferroli, do not prohibit unauthorized installation of a wall-mounted boiler, but still require the involvement of specialists with permission to connect electrical and gas equipment.

Thus, if you plan to install the boiler yourself, before purchasing it, make sure that this is permitted by the manufacturer.

Requirements for the boiler installation location

It is better to install a mounted boiler in a separate room, which is called a furnace or boiler room. The requirements for such a room depend on the type of boiler being installed, or more precisely, on the type of its combustion chamber.

Open combustion chamber

The operation scheme of such a device is identical to a conventional stove, which takes air from the room and removes exhaust gases through the chimney using natural draft. Such boilers require a certain volume of air in the room, otherwise the gas will not burn completely, forming toxic substances that are hazardous to health. In addition, when installing a wall-mounted boiler, it is necessary to provide a window to the street with an area of at least 0.5 square meters. m., as well as a place for maintenance. The walls of the room must be treated with fire-resistant materials.

The volume of the boiler room depends on the total power of the connected heating devices: 8 cubic meters. m. with a boiler power of up to 30 kW, 13-14 cubic meters. m. for 30–60 kW and 15 or more cubic meters. m. for powers up to 200 kW.

Closed combustion chamber

Such boilers are equipped with a special coaxial chimney. It is a double pipe, the outer part of which is used to take air from the street, and the inner part is used to remove combustion products. Installation of such systems requires a mandatory connection to an electrical network to power a fan, which circulates air through a closed chimney.

Boilers with a closed combustion chamber are more environmentally friendly and safe, so they can be located directly in a living space (in the kitchen, bathroom, pantry, etc.). In this case, the requirements for the parameters of the chimney are not standardized, since the removal of gas waste is completely controlled by automation.

In city apartments it is allowed to install only heating boilers with a closed combustion chamber.

Installation process of a wall-mounted boiler

Installation and connection of a wall-mounted boiler is an important and critical part of the implementation of the entire heating system. The order and specifics of the work depend on the type of combustion chamber and the number of circuits used (heating only or heating plus water supply).

Since the use of single-circuit boilers with a closed chamber is now more common, the entire installation process will be described specifically for such a modification. Where necessary, notes will be made about the installation features of a particular type of gas boiler.

Wall mount

The gas mounted boiler must be mounted on a special bracket, which is included in the delivery package. For correct installation The fastening elements that are inside the box are not always suitable for the bracket. They may have to be selected separately, taking into account the material of the wall on which the boiler is supposed to be hung.

In case of difficulties, it is better to contact specialists in any construction market. The wall bracket must support the weight of the boiler and all attachments and ensure its level, without distortions, position.

Parts of the walls located directly behind the heating unit must be protected with fireproof material. The hanging height of the lower part of the gas boiler is at least 800 mm, the distance from the wall to the rear surface of the boiler is 5 cm.

Connecting main heating pipes

The number of pipes that need to be connected to the boiler depends on the type of heating system (one-pipe or two-pipe). In any case, before making connections, it is necessary to remove the protective plugs from the boiler pipes.

Particular attention must be paid to the quality of water, especially its hardness. If this parameter does not meet the manufacturer's requirements, it is advisable to use special cleaning equipment, for example, polyphosphate dispensers. Otherwise, the wall-mounted boiler may quickly fail.

Gas connection

The connection of the heating boiler to the gas pipeline must only be carried out by a specialist with the appropriate permit. During the work you will need to install:

Ball gas valve. It is placed directly at the entrance to the wall-mounted boiler;
Gas meter and leakage sensor. They cut into the main line up to the boiler and serve to account for gas consumption and ensure safety;
Thermal shut-off valve. Its presence is prescribed by the rules fire safety. When the temperature near the wall-mounted boiler rises to certain value(for example, in case of fire) this valve automatically shuts off the gas supply.

Electrical connection

This work is not necessary for all boilers. For atmospheric units with an open chamber, electricity is not necessary. Boilers with closed chambers have a fan for removing gas waste and an automation system, to which the power supply must be connected. Typically a three-wire connection circuit (with grounding) is used.

It is highly advisable to connect the mounted boiler to the electrical network through a voltage stabilizer. This will help avoid sudden voltage surges and extend the life of expensive gas equipment.

Output to the chimney pipe

For atmospheric gas boilers, a prerequisite is a connection to an individual chimney. The wall-mounted boiler is connected to the chimney using iron pipe of the required cross-section, resistant to high temperatures, the effects of combustion products and mechanical wear.

Before making connections, it is advisable to make sure that the chimney is not clogged with installation debris and soot residues. To install the pipe section from the boiler to the chimney, the following rules must be met:

The vertical section at the outlet of the gas boiler must have a length of at least two diameters before turning;
Next, the pipe is inclined towards the boiler;
The connection section to the chimney should be as short as possible.

In boilers with a closed chamber, the removal of combustion products is much easier. Such boilers can be connected to collective chimneys or use a coaxial pipe that goes outside through the wall. If you are installing a wall-mounted boiler with a closed chamber, then there is no need to monitor the height of the gas pipe: the built-in fan will create the necessary draft in it.

Filling the system with water

Before a test run, the heating system must be filled with water. To do this, you need to open the valve, which is usually located at the bottom of the wall-mounted boiler. Water must be pumped until the pressure reaches approximately 2 atmospheres.

It is advisable to carry out this process as slowly as possible in order to ensure the removal of the air present inside.

At the same time, the entire heating system circuit must be checked for leaks.

First start

To start a wall-mounted boiler for the first time, you must invite a certified specialist. As a rule, most companies involved in the sale of boilers and equipment for heating systems have trained employees. He will make all the settings and check the operating modes of the system.

During the commissioning process, it is better to ask him all the questions you have about the control and features of using heating system devices. If everything works fine, you can sign the commissioning certificate and enjoy the warmth and comfort of your home.

Let's summarize: installing a wall-mounted gas boiler is a rather complex and painstaking engineering operation that requires experience in construction, installation and plumbing work and the mandatory presence of specialists at some of its stages. However, by performing independently those steps that the technical process allows, you can not only save a lot on the services of an installation team, but also get a feeling of deep satisfaction from a serious job done correctly.
