Fig.1. Mounted gas boiler 25 KTV PANTHER
1 – closed (sealed) combustion chamber (turbochamber); 2 - atmospheric burner; 3 - heat exchanger; 4 - circulation pump; 5 - air vent; 6 - heat exchanger of the DHW system; 7 - three-way valve drive; 8 - gas valve; 9 - ignition electrodes; 10 - control electrode; 11 - ignition unit; 12 - control panel; 13 - heating temperature sensor; 14 - emergency sensor temperature; 15 - traction sensor; 16 – fan; 17 – water pressure sensor
The boiler is designed to operate in a temperature range from +5 to 40 °C and relative humidity up to 85%.
The temperature of the external surfaces of the boiler unit (side and top cover) during boiler operation should not exceed the ambient air temperature by no more than 50°C.
When placing the boiler, it is not allowed to place objects near it:
From flame-resistant materials - at a distance of less than 100 mm from the surface;
Made from flammable materials, such as fibreboards, polyurethane, lightweight PVC, synthetic fibres, rubber, etc. - at a distance of less than 200 mm from the surface.
It is necessary to leave a free space of at least 1 m in front of the boiler to carry out maintenance work.
In the Protherm Panther 25 KTV boiler, the removal of combustion products and the supply of air for combustion are carried out by a special coaxial pipeline or separate pipelines.
From standard parts you can create a coaxial chimney for almost all installation options. The length of the chimney, type and number of sections must be agreed with the service organization.
The chimney must be laid in such a way that condensate from combustion products can be removed. For this purpose, there are special sections that are built into the chimney route.
The gas boiler Proterm Panther 25 KOV is designed to discharge combustion products into a chimney with natural draft. The boiler is connected to the chimney using a pipe with a diameter corresponding to the size of the chimney pipe.
It is not allowed to install objects into the pipe that restrict the passage of combustion products (for example, different kinds heat exchangers-heat recuperators, etc.).
Installation of gas boiler Proterm Panther
The Protherm Panther 25 KTV (KOV) boiler should be installed in closed heating systems with water as the coolant. The nominal diameter of the system pipes is selected based on the characteristics of the pump. The piping is designed according to the required capacity of a given system, and not the maximum
boiler heating capacity.
In this case, the coolant flow should be such that the temperature difference between the supply and return is no more than 20 °C. The minimum water flow in the system is 500 l/hour. The piping system must be designed to ensure that air is removed from it.
Air vents are located at the very high place in the system and on all radiators. The heating system is filled to a pressure of at least 1 bar. The recommended pressure range in the system is 1.2 – 2 Bar.
Expansion tank The boiler is designed for a heating system capacity of 95 liters. In larger systems, another membrane-type expansion tank should be installed. Heating radiators can be equipped with thermostatic valves.
If the unit is controlled by a room regulator, the thermostatic valves are not installed in the room where the room regulator is located. The system must be thoroughly cleaned before installation.
DHW system
The water pressure in the DHW system should be in the range of 1 - 6 Bar. If the pressure exceeds 6 bar, a pressure reducing valve must be installed at the inlet. At high hardness tap water it is recommended to take appropriate measures to reduce it.
The connecting pipes have external threads. They must not be loaded with the weight of pipes from the heating system, hot water supply system or gas supply. It is necessary to strictly observe the installation dimensions of the connecting pipes (height, distance from the wall and between individual inlets and outlets).
At the bottom of the boiler there is a hydraulic group, which is equipped with a safety relief valve, a system filling (priming) valve and drain tap. If the maximum pressure in the system (2.5 kgf/cm2) is exceeded, water may flow out of the safety relief valve or steam may escape.
Connecting the boiler to heating system It is recommended to carry it out in such a way that when repairing it, it is possible to drain water only from the unit. The heating system can be replenished (in small quantities) using a refill tap.
The drain valve is designed to reduce the water pressure in the boiler during possible repairs. This tap can only partially drain the water from the boiler. Complete drainage of water or the entire heating system, as well as refilling, must be carried out using fill and drain valves (plugs) installed in
certain areas of the heating system.
Filling the Protherm Panther boiler and the system with water should be done in the following order:
Check that the pressure in the DHW system is higher than the water pressure in the heating system.
Carefully open the filling valve in the hydraulic group and at the same time monitor the pressure increase on the boiler pressure gauge. The tap opens by turning it counterclockwise, and turning it clockwise closes it.
When the required pressure is reached, the filling tap must be carefully closed and checked to see if the water pressure increases (the tap must be completely closed).
If the DHW pressure in the water supply is the same or lower than the pressure in the heating system, water may leak into the water supply, which is unacceptable. This can be prevented by setting check valve on the water supply pipe to the boiler.
During repairs, unfavorable building layouts, etc., you can connect the boiler to the heating system, hot water supply system and gas supply with special flexible hoses.
When using flexible hoses, they must have a length of no more than 0.5 m, protected from mechanical stress and damage, and exposure to aggressive substances. At the end of their service life, the hoses must be replaced with new ones. To connect the boiler to a pipeline made of copper pipes, you can use a special connecting set of shaped copper pipes with fittings.
Tube sizes:
OB inlet and outlet – tube diameter 22 mm.
- DHW inlet and outlet – tube diameter 15 mm.
- Gas connection – tube diameter 22 mm.
- Connection safety valve– tube diameter 22 mm.
Gas connection
Size 25 KTV (KOV) - ZP is designed to operate on natural gas with a nominal pressure of distribution network 1.8 kPa, and calorific value 35900 kJ/m3. The diameter of the pipes, fittings and gas meter must be selected taking into account other gas appliances of the consumer. It is necessary to connect a pipe to the boiler with a minimum connecting diameter of 1/2“, but it is better with a nominal diameter of 3/4“.
Size 25 KTV (KOV) - P is designed to operate on liquefied gas (propane), with a calorific value of 12.3 to 13.0 kWh/kg.
Due to the fact that the operation of a boiler using cylinders is problematic, first of all, from the point of view of ensuring a sufficient number of them, as well as their further use, the simultaneous use of a gas tank near a heated facility and its filling by an authorized organization are provided.
Calculations of the required sizes of propane supply from the gas tank to the boiler unit or to other gas appliances are part of the design and delivery of the gas tank. Using a gas pressure reducing valve, it is necessary to ensure a nominal gas pressure in front of the boiler of 3.0 kPa.
Air supply and combustion products exhaust
Is air supplied and combustion products removed through an external coaxial pipeline? 100 mm. The equivalent pipeline length (numerically equal to the sum of linear meters of a straight pipe and the number of 90° elbows) should be no more than 9 m. For an equivalent pipeline length of more than 3 m, the throttle washer must be removed from the fan outlet.
Horizontal sections of the pipeline must be installed with a slope of at least 1.5% towards the flue gas outlet so that condensate flows out of the pipeline. In vertical sections, condensate drainage devices are used.
The pipeline outlet should be located:
At a height of at least 2 m from the foundation of the building in places visited by people and at least 0.4 m in places not visited by people;
At a distance of at least 0.5 m horizontally from windows, constantly open ventilation grilles and doors;
Above the top border of windows, bars or doors;
In the area under awnings, balconies and roof edges.
Minimum distance between two adjacent pipeline outlets:
Horizontal – 1 m;
- vertically – 2 m.
The direction of the pipe exit should be oriented so that combustion products exit into open space.
The horizontal distance from the end of the pipeline outlet on one facade to the other, with opposite placement of outlets, should be:
2 m, if there are no windows or grilles on one facade;
1 m if both facades are without windows or bars;
4 m if both facades have windows or bars (or if there are adjacent exits on the same facade).
In the niche of the building facade, the distance between the axis of the pipeline outlet and the adjacent plane of the facade should be:
2 m if there are windows or bars on the facade;
- 0.5 m - if they are absent.
All distances are given from the outer boundary of the window (grid) or door to the axis of the pipeline. In the space under the canopy (balcony), the head of the pipe must be at a distance of at least the radius of the circle.
When pipelines exit vertically onto the roof, their heads must be placed at a distance of at least 0.4 m horizontally and at a height of at least 0.4 m from the roof surface, taking into account its shape.
The chimney outlet must not be located in an explosive area, internal parts buildings or structures, tunnels or underground passages, in closed spaces.
The hole in the wall for the passage of the coaxial pipeline is made with a certain gap (from 10 to 15 mm). Upon completion of installation, the gap is insulated with non-combustible materials ( polyurethane foam, gypsum, plaster).
Electrical connection of the gas boiler Proterm Panther
The Proterm Panther boiler must be connected to the electrical network through a plug socket with a grounding contact, which eliminates the “zero-phase” connection error. The distance from the boiler to the socket must be within the length of the boiler power cord (1 m).
The boiler must be connected to protective conductor(grounding). The grounding conductor must be accessible for inspection and resistance testing.
For electrical connection It is not allowed to use various tees, extensions, etc. The boiler is protected from overload and short circuit by fuses P1 – T80 mA/250V, P2 – T 1.6 A/250V, installed in the control panel. Before working with the electrical equipment of the boiler, it is necessary to disconnect the boiler from the network by disconnecting the electrical plug from the socket.
To control the boiler from a room regulator, use a regulator with a potential-free output (other than the mains voltage, no other voltage is allowed to be supplied to the boiler). Connect the room regulator to the unit with a flexible two-core cable with a cross-section of 0.5 to 1.5 mm2. Exit the cable from the boiler through a plastic cable sleeve.
The terminal block for connecting the room regulator and external sensor is located at the bottom, inside the boiler and is accessible after removing the outer cover and turning the control panel. Before connecting, the jumper must be removed from the terminal block. The minimum load of the regulator output contacts is 24 V / 0.1A.
The outside temperature sensor should be connected with a two-core copper conductor with a cross-section of 0.75 mm2. The wiring resistance should be no more than 10 Ohms, maximum length - 30 m.
The circuits for connecting the outside temperature sensor and the room regulator must not be laid together with the mains voltage circuits.
Work on putting the Protherm Panther boiler into operation:
Remove the screw securing the lid at the bottom of the boiler;
Tilt the cover down (toward you) and lift it off the pins at the top of the camera.
Make sure the gas supply is turned off.
Loosen the cap on the automatic air separator located on the pump.
Connect the boiler to the electrical network.
Turn the power switch to position “I”. The display will show code F0 and the pump will run for approximately 1 minute.
Press the Bar/Mode button. The display will show 0.0 (pressure value) and the LED will light up.
The pressure value is displayed for about 25 seconds. After this, the display returns to its original position. The pressure value can be displayed again by pressing the Bar/Mode button.
Fill the system with water, the pressure should be between 1.2 and 2 bar.
Carefully release the air from all heating devices (the flow of water should be continuous, without air bubbles).
Leave the cap on the air separator loose while the boiler is operating.
Open the DHW taps to remove air from the DHW circuit;
Make sure that the pressure shown on the display is in the range of 1.2 - 2 Bar, top up if necessary.
Starting the Proterm Panther boiler
Before starting the boiler, check:
The main gas supply valve is open,
- the gas valve at the inlet is open,
- closing valves (water, heating) at the outlet are open,
- the unit is connected to the electrical network.
To start the Protherm Panther boiler, do the following:
Switch the power switch to position “I”;
Set the extract air temperature to 85 °C and switch off the equithermal control (E-).
Check the condition of the room regulator (it must be closed);
Smoothly raise the temperature in the heating system to maximum (all radiators should have open valves). The air in the water of the heating system is gradually removed through an automatic air separator. There should be no air at the highest point of the system and in the radiators;
Make up the system to a pressure of 1.2 Bar;
Turn on the boiler again and heat the system to maximum temperature;
Turn off the boiler, remove air if necessary and refill the system with water;
Make sure that after the heating system has cooled down, the pressure gauge shows at least 1.2 Bar;
If the pressure in the heating system in the heated state is higher by. 0.5 bar than when cold, check the setting of the expansion tank relative to the system.
Protective functions of the Proterm Panther boiler
The boiler is equipped with a frost protection function. When the temperature drops below 10 °C, the pump will automatically turn on. When the temperature drops below 8 °C, the device will ignite and operate until the temperature rises by 25 °C. If it freezes (exhaust temperature below 3 °C), the boiler start-up is blocked.
The pump switches on automatically for a short time if it has not been switched on for 24 hours. This ensures protection against blocking due to deposits during prolonged shutdown. The pump operates continuously when the temperature rises above 85°C (overheat protection).
When the pressure drops, the LED flashes; when the pressure drops further, the unit goes out (protection against water loss - alarm F0). When the pressure increases, operation automatically resumes.
The protective functions are only activated when the boiler is connected to the mains voltage (the electrical cord is in the socket and the mains switch is in the on position (I).
If the boiler has been disconnected from the mains voltage for a long time (a month or more), it is recommended to start it periodically (at least once a month). The boiler is equipped with a safety valve. When discharging heating water from the valve, turn off the boiler and disconnect it from the mains voltage.
Adjusting the Protherm Panther boiler
When the boiler operates without a room regulator, it maintains the temperature set on the display.
Adjustment operations:
– select the equithermal regulation mode – select the heating curve and set the E- symbol;
– select the equithermal regulation mode – in the parallel movement option put the symbol P-;
– select the Exhaust temperature mode and configure it;
– the room regulator must be turned off, and a jumper must be installed between the terminals to connect it.
When the Proterm Panther boiler operates with a room regulator, it maintains the temperature set on the display. In this case, the unit turns off according to commands room thermostat installed inside the control room. There should be no thermostatic valve on the radiator in this room.
During installation, the jumper is removed from the boiler terminals and the room thermostat is connected. When operating in equithermal mode, the temperature changes depending on the change in outside air temperature.
An outside air temperature sensor must be connected to the boiler. The sensor is installed on the coldest wall of the building (north or north-west) at a height of about 2.5 - 3 m. The sensor should not be located in the area of ventilation emissions from windows or other ventilation devices
and be exposed to direct sunlight.
Inlet gas pressure control:
Turn off the boiler.
Loosen the screw on the pressure measuring fitting of the gas valve;
Connect the appropriate pressure meter;
Carry out a launch;
Check the gas inlet pressure, if it is below normal, check the tightness of the gas pipeline;
Turn off the unit and disconnect the pressure meter, carefully tighten the screw on the measuring fitting and check its tightness.

We looked in detail electric boilers Proterm Heating ramp, entire model range and technical specifications. Having disassembled the internal structure according to the operating instructions, we identified the main advantages and disadvantages of these devices. We also focused on possible errors if malfunctions occur and some ways to fix them yourself. Let's watch the video.
The well-known Slovak company Protherm has gained trust due to the high quality and reliability of the equipment it produces. A careful study of customer needs and trends in demand for various models of manufactured devices allowed the company to gain a leading position in the market.
The company produces dozens: floor-mounted and wall-mounted, and with open and closed combustion chambers. Proterm double-circuit wall-mounted gas boilers, to which this article is devoted, have gained particular popularity.
Description of the Proterm double-circuit boiler
Boilers that have the function of heating domestic water are called double-circuit because they heat water for two systems - the heating circuit and the hot water supply system (DHW).
The DHW system in such boilers, if necessary, can operate separately from the heating system. This mode is necessary to supply the home hot water in summer time.
Wall-mounted double-circuit models are presented in a wide power range - from 11 to 30 kV, which allows the buyer to choose best option depending on the heated area.
IN wall-mounted boilers a mechanism is provided to release the combustion chamber from exhaust gases. This is done in two ways. The first is the forced removal of residual gases using a fan; such a combustion chamber is called closed. The second option is that the gases are given the opportunity to independently exit the room through the chimney; this chamber is open.
All Proterm products are equipped with the most modern systems automatic control, management and protection.
Distinctive features
By installing a Proterm double-circuit gas boiler in your home, you will become the owner of a real home boiler room, which, in addition to standard functions, will provide your household and hot water.

Construction of a Proterm gas boiler
Various modifications have individual characteristics devices.
Manufacturing boilers using low-temperature cast iron helps to effectively minimize heat losses. A special feature of the design of heating devices of the Proterm brand is also an unusual, fairly environmentally friendly method of burning fuel.
The main components of gas heating equipment are presented:
- ignition system;
- burner;
- heat exchanger.
The heat source is represented by the flame of a burner in which gas is burned, and a heat exchanger is responsible for heating the coolant. The gas supply process is regulated by a thermostat, while combustion products, represented mainly by water vapor and carbon dioxide, are discharged through the chimney system.
