Installation of a gas boiler in a private house requirements: sequence of work on installing gas boilers. Gas boiler in a private house: requirements and installation Instructions for installing double-circuit boilers

In all cases, wherever it is planned to place the gas boiler, on the floor or on the wall, installation is carried out accredited specialists from Gorgaz.

Gas supervision will allow installation, only if there is a certificate of conformity purchased equipment.

Installation of a wall-mounted gas boiler. Materials and tools

Having chosen the model you like, ask how to mount it on the wall and What is included in the kit for this? to the boiler (hooks, power dowels). If the heater is sold without mounts, they will have to be purchased additionally.

Refuse to purchase if the unit is manufactured not a very reputable manufacturer. Either this is a novice supplier, or, more likely, not particularly concerned about quality.

After paying for your purchase, you can take it home and start installing it on the wall. To do this you will need tools:

electric drill or hammer drill;
metal pipes;
building level(preferably laser).

Using the latter, they check how level the unit is installed. This is especially important for condensing gas boilers. The slightest deviation from the vertical guarantees breakdown, and in the near future.

Preparing the installation site

It should be remembered that the room where the gas boiler will be installed is considered explosive and must meet many criteria established by law. Therefore, before placing an order, you should make sure that this is possible in your home, otherwise the purchase will become absolutely useless: Gorgaz will refuse to approve the procedure.

Usually a wall-mounted boiler is installed in the kitchen. Except ventilation and through hole on front door(and in all cases it should go outside), pay attention to the wall itself. Make sure that it is strong and can withstand the installation of power fasteners, and even the boiler on it. For this strengthen the wall wooden dies . The wall covering should be non-flammable. If there is a risk that it will catch fire in a fire, a layer of non-combustible material is placed on the wall, followed by a boiler.

Photo 1. Approximate Dimensions wall-mounted boiler and the norms for its placement in relation to adjacent walls, floor and ceiling.

The unit, according to the standards, approximately 45 cm from the wall. Therefore, it must be mounted not directly on the panel, but on bars previously attached to the wall. Height from floor must be from 0.8 to 1.6 m. The remaining walls are tiled for aesthetics ceramic tiles.

Attention! When installing a condenser gas unit you need to remember that it hang with a slant away from you, that is, the distance between the wall and the boiler at the top is slightly less than between the wall and the bottom of the unit.

Hanging the boiler

The installation procedure consists of the following steps:

unpacking boiler;
reconciliation of markings on the case with data in the certificate and invoices for the device;
screwing the bracket or other suitable fasteners;
removing factory plugs from the unit;
flushing internal pipes.

Now the boiler can be hung in the desired place. Check horizontality boiler, adjust its position if necessary.

All that remains is to connect boiler to the system. If the master has already come on call, you can involve him in the work.

Chimney in a private house

The most common boilers found in homes are with closed firebox. This is understandable: they are easier to use, it is easier to connect them to the chimney - you just need to screw them on coaxial pipe. In private houses, the coaxial chimney is removed out through the wall.

Photo 2. Diagram of the smoke exhaust from a gas boiler through the nearest wall. The movement of flue gases and air is shown.

There are no strict requirements for the hanging height of the pipe, since draft is provided by the built-in fan. An open firebox implies the installation of an individual chimney, and Special attention you will have to pay attention to the cross-section of the pipe.

Attention! When purchasing a pipe, look at what it is made of. Suitable for work only wear-resistant materials, not afraid of the vagaries of temperature and the effects of combustion products.

Connection to the heating system

What needs to be done actually the same as when connecting heating. The difference lies in the taps and pipe diameters.

A filter is placed on the “cold” pipe, which will prevent dirt and metal particles from entering the heater.

Shut-off valves with detachable connections(so-called American women). It is much easier and faster to work with them, and if the faucet fails, it is easy to replace it with a new one.

Cold pressure pipes connect on the left, orienting from the center of the unit, hot - on the right side.

How to connect to a gas source

The gas line branch is connected with a flexible connection to the pipe on the heating unit. Shut-off valve must be equipped with a hermetically sealed filter. Sealing threaded connection carried out using paint and tow.

Do not use rubber hoses, they do not last long. Usually the Gorgaz representative stipulates this at the very beginning. Best suited corrugated hose made of of stainless steel .

In the room where the wall-mounted heating device is installed, a gas sensor connected to a relay is required. If a leak occurs, the sensor gives a command to block the gas.

Will work at the same time sound alarm , notifying the owner of a breakdown.

Advice. This part of the work, as well as the first launch, is mandatory entrusted to an accredited representative of Gorgaz with permission from a self-regulatory organization!

Double-circuit and single-circuit gas boilers

Differences in operating principle of these two units are as follows. Dual-circuit the heater will not only provide hot water from the tap, thanks to it, all systems work as before, as if the hot water had never been turned off - This includes water supply, batteries, and even heated floors. The heat exchanger heats the water coming from the cold supply system.

Photo 3. Diagram showing the differences between single-circuit and double-circuit wall-mounted boilers. The first requires a boiler.

Dual circuit unit only contains three-way valve, which regulates the direction of coolant flow. The heated water is directed towards the central heating. When a hot tap is opened, a sensor inside the unit switches the three-way valve to another position - water flows into the heat exchanger, where it heats the water.

Attention! Bye hot tap open, the so-called a priority hot water , that is central heating closed. Users often regard this nuance as an inconvenience.

So that you don’t have to wait for a hot stream (usually it appears half a minute or even more after opening the tap), It’s better to buy a flow-type boiler with built-in boiler. However, this option is only suitable for apartments or small houses. For a large mansion or estate it is unprofitable.

Single-circuit The boiler is only useful for heating cold water coming from the water supply.

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 greater productivity is required, they are mounted on the floor. The advantages of 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 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 ground floor, but they cannot be placed 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 network(in exactly 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.

Typically, wall-mounted models have a bottom connection to the circuits. 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 of the entrance door or in the wall partition separating the boiler room from the adjacent room. Width 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:

Diameter exhaust pipe the chimney cannot be less than what is 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, cylindrical chimneys are recommended. It is best if the pipe is made of black or 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 a wall-mounted 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, shut-off valves are installed on both sides of the filter, allowing the boiler to be serviced 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. In them, combustion products are removed by a 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.

Mounted under a floor-standing boiler solid foundation, 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 required 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. The hot water supply is connected to the top pipe of the unit, and the return to the bottom 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 a certain part installation work can be done 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.

The task is not easy. The boiler cannot be hung haphazardly, since the safety of the people living in the house often depends on how correctly the wall-mounted boiler is installed.
This means that the installation of this device is carried out in strict accordance with technical requirements and standards adopted in Russia at the legislative level.

That is why installing a wall-mounted boiler with your own hands is an extremely labor-intensive and difficult process for a beginner.

Stages of preparation for boiler installation

Before the owner of the house starts, you will need to collect some documents:

agreement on supplying the house with gas;
technical specifications and installation diagram gas system, approved by the relevant authorities;
written permission from the gas inspector to install the equipment.

Boiler installation rules and regulations

Gas heating equipment is installed in accordance with developed and approved technologies that ensure the safety of its operation.

The question of how to install a wall-mounted boiler begins with preparing the room for it. The room must meet certain requirements: the boiler room can be located anywhere in the house, except the bathroom, living rooms and a bathroom. However, when installing wall units, this requirement may be relaxed depending on the type of boiler. The volume of the room is from four square meters, the ceiling height is from two meters. The width of the doorway is at least 800 mm. Also in the room there should be natural lighting of the boiler through the window. In this case, the window size must correspond to 0.3 square meters. for every 10 sq.m. premises.
The rules for installing a wall-mounted gas boiler regulate the supply of a certain volume of fresh air using supply ventilation to the place where the boiler is used. An insufficient amount of incoming air may be due to the accumulation of a substance hazardous to health and life in the room.
: the standards for its placement are such that there must be more than 10 cm from the wall to the surface of the boiler. If this distance is less than required, the wall must be protected with a fire-resistant coating.
Gas pipes can be metal, but not plastic.
The chimney opening must correspond to the power capabilities of the boiler. In this case, its height must be at least 5 m, provided that the chimney is installed above the ridge on the roof of the house. When installing a chimney, it can have no more than three bends.
When organizing a power supply system, it is necessary to provide a circuit breaker with current protection and thermal protection.
In the room where the boiler will be located, there must be a gas sensor connected to a relay. In the event of a gas leak, the sensor must send a relay signal to block gas flow. In addition, an audible alarm should sound.
Installation of a wall-mounted gas boiler; when starting it up, regulations require that the device be provided with a gas meter.
If there are other gas appliances near the boiler, then the distance between the appliances is set at at least 20 centimeters.
When installing, the requirements even affect the completeness of the equipment. The boiler package must comply with the standards and contain: a manual, fasteners, a paper template for installation, special keys and fasteners.
The installation height of the wall-mounted boiler is 80 cm - 160 cm from the floor surface.

If all these requirements are met, then there is no doubt about the reliability and fire safety of the system. gas heating. Please keep in mind that the heating system must be checked regularly Maintenance by employees of the city gas service.

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-flammable 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 bottom 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:

The premises in which the gas boiler will operate are specified in SNiP 31-02-2001, DBN V.2.5-20-2001, SNiP II-35-76, SNiP 42-01-2002 and SP 41-104-2000 - these documents eliminate or minimize any emergency situations. Premises for placing gas boilers fall under the classification of fire and explosion hazards, therefore, when designing, planning, installing and setting up equipment for gas heating, all requirements for the premises for installing a gas boiler must be strictly observed.

General requirements for the installation of gas appliances

In the room intended for the installation of a gas boiler, according to the above standards, there must be good natural lighting: per 1 m 3 there must be at least 0.03 m 2 of window opening area (but not windows - partitions, frames and imposts are not taken into account). It is imperative to equip the room with a supply and exhaust ventilation system according to following rules: the total volume of forward and reverse air flows per hour, multiplied by 3, is equal to the volume of the total exhaust device. In addition to a window equipped with a window, a door with access to the street is installed in the room. The table shows the requirements for room volume:

Attention!

For gas-fired units with a power of more than 6000 W, 0.2 m3 should be added for each extra unit of power.

Supervisory requirements for the premises for installing a gas boiler stipulate that the operation of any appliances for heating an apartment is permitted on each floor multi-storey building and in any room of the apartment. Kitchens in multi-storey buildings also meet these requirements, since they are already equipped with appropriate communications. The only condition is general thermal power all devices for heating water and heating the apartment (boilers, boilers, heating elements, heating radiators, batteries or registers) should not exceed a total of 150 kW.

The ceiling height in the room is 2 meters or more. The room in which the gas boiler will be installed and operated must be separated from adjacent rooms by solid fire-resistant walls. Material for walls or partitions must have a fire resistance time limit of 0.75 hours (45 minutes). The boiler room must be designed so that in the event of an operational fire there is no possibility for the fire to spread throughout the apartment.

Attention!

Gas boilers of the TLO brand, operating on the principle of natural coolant circulation, can be installed and should be operated only in the basement of the house or in the basement.

Installation of a gas wall-mounted boiler - kitchen requirements

Ceiling - 2 meters and above.
The total volume of the kitchen is more than 7.5 m 3, ventilation is equipped, a window is installed and there is a door opening onto the balcony.
For air exchange, it is necessary to install a grille at the bottom of the wall or door that opens into the next room; the area of the grille is at least 0.02 m2.

To install a gas boiler in the kitchen, you may need permission from the gas service.

If the kitchen in the apartment does not meet the requirements of SNiP, then gas heating equipment can be installed and operated only with the permission of the gas supervision authority.

The existing rules for installing a gas boiler in a private house largely repeat the requirements for boilers that operate in apartments multi-storey buildings. The differences are caused only by the fact that often in a private house a separate room or building is allocated for heating equipment, which is subject to additional requirements listed below.

Rules for installing a floor-standing gas boiler

In a house under construction, it is necessary to plan a separate room for installing a gas-fired boiler. The room should have a natural flow of air through a grille in the door or through a hole in the wall.
A separate hole must be made for supply and exhaust ventilation - it must be located under the ceiling.
A hole in the wall for the chimney pipe, a hole below the chimney for a soot brush (for cleaning the chimney pipe), which is made below the main chimney by 20-30 cm.
The chimney is made airtight so that smoke and carbon dioxide do not flow back into the room. For tightness inside big pipes A pipe of smaller diameter is installed in the chimney, through which gas combustion products are discharged.
The room intended for installation and operation of a gas boiler must be spacious and provide easy access and operation, maintenance and repair of the boiler. The floor in the furnace room must be made of non-combustible materials - concrete screed, natural stone, paving stones. The furnace room must be connected to the water supply for the operation of the water heating device, and be equipped with a sewerage system.
The area of the room for the boiler is 4 m2, the height of the ceilings in the room is at least 2.5 m2.
Exterior door should be 80 cm wide.
The top of the chimney should be higher than the roof. The cross-section of the chimney pipe should be larger diameter boiler outlet.
To supply power, the boiler room must be equipped with an electrical panel with grounding.
The gas line is brought into the room in advance. A separate valve must be installed for each gas appliance.
The walls of the boiler room are plastered - it is strictly prohibited to decorate the walls with flammable materials (MDF, fiberboard, plastic).

It is prohibited to store flammable liquids and objects near the furnace room and in the room itself. The foundation under (a gas heating unit or a gas heating water heating unit) should not freeze in winter, therefore its depth should be below the level of soil freezing in a given region. Air from vent must be clean, that is, the chimney must be located far from the ventilation hole. The room or building in which the gas boiler is installed cannot be equipped for other purposes.

Rules for installing wall-mounted gas boilers in an apartment

Typically, in an apartment, a gas boiler is installed in the kitchen, since it already has a gas line, water supply and sewerage. That is, a priori, all requirements for the installation of gas equipment have already been met - all that remains is to connect the boiler. This state of affairs automatically reduces the cost of laying engineering communications and energy resources. It is prohibited to install a gas boiler in rooms with high humidity - in a bathroom, laundry room, etc.

There are several additional requirements for wall-mounted boilers:

The wall or partition for hanging the boiler must be able to support it - equipment cannot be hung on a plasterboard or other light partition.
If the wall is decorated with flammable materials (wallpaper, vinyl, plastic, MDF, fiberboard), then a 3 mm thick gasket of non-flammable material is installed between the wall. The boiler must be secured special hardware, which provide a distance from the boiler body to the wall of at least 4-5 cm.
The minimum distance from the boiler to the ceiling and walls of the room is 0.5 meters. The distance from the boiler to the floor is 0.8 meters.

Before installing and starting up gas equipment, you must obtain all relevant documents. The main condition when installing a boiler in a private house that runs on gas is that an agreement on connecting the gas main is first concluded, and a project for the installation of gas equipment and gasification of the house is drawn up. These documents are developed and approved by the gas supplier in the region.
