Installation, connection and startup of the Proterm Panther boiler
Mounted gas boiler Proterm Panther 25 KTV with forced exhaust of combustion products and model 25 KOV with natural exhaust, operating on natural gas or propane, are intended for heating and hot water supply country houses, cottages, small garden buildings, communal buildings and other objects that are equipped with a heating system with forced circulation of coolant and running water.
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 temperature sensor; 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 fibers, 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.
At the boiler Protherm Panther 25 KTV, the removal of combustion products and the supply of air for combustion is 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 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 highest 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
Water pressure in DHW system should be in the range 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 a drain valve. If exceeded maximum pressure in the system (2.5 kgf/cm2), water may flow out of the safety-relief valve or steam may escape.
It is recommended to connect the boiler to the heating system in such a way that during its repair 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.
Upon reaching required pressure 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, DHW 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 in the distribution network of 1.8 kPa, and a calorific value of 35900 kJ/m3. Pipe diameter, 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, it is planned to simultaneously use a gas tank near the heated object and fill it with an authorized organization.
Calculations required sizes supplying propane from a gas tank to a 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. Equivalent pipeline length (numerically equal to the sum linear meters straight pipe and the number of elbows 90°) 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 outlet flue gases 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 that are 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 a 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. 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.

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.
Pump on a short time turns on automatically if it has not been turned 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 mains voltage ( electrical cord is in the socket, and the power 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.

— traditional mode for heating (25-85 °C);
— “warm floor” mode (30-45 °C);
— hot water preparation mode in an indirect heating boiler (35-70 °C).
The multifunctional LCD display informs about the temperature in the heating circuit and the boiler, as well as about problems and errors in the operation of the boiler in case of any malfunctions. Above the display there are lights that light up depending on the set operating mode of the device, changes in power consumption and insufficient water pressure in the system.
By default, all Protherm electric boilers are 3-phase, however, low-power models of 6 and 9 kW (“Skat 6K” and “Skat 9K”) can be connected to a single-phase 220 V network. Medium power devices are designed for heating houses with an area of up to 180 m2, and high-power boilers - more than 20 kW can be installed in private houses or other premises with a total area of up to 280-300 m2. Let's look at the table.

Features of the Proterm electric boiler
The heating apparatus consists of several main elements necessary for its full operation.
1. Cylindrical copper heat exchanger for heating the coolant.
2. Block of heating elements made of copper of different power and quantity with multi-stage switching.
3. Expansion tank 7 liters to compensate for thermal expansion in the heating system.
4. Hydraulic group consisting of:
- three-speed circulation pump ;
— safety valve at 3 bar;
— automatic air vent.
Also on line heating circuit An NTS temperature sensor is installed, as well as an emergency sensor that protects the unit from overheating. There is a system to protect the device from freezing. and from blocking the circulation pump.
Electric heating elements are built into the heat exchanger of the Proterm boiler, top and bottom. Depending on the model, the number of heating elements may vary. For example, in Skat 6K, 9K, 12K and 14K devices two heating elements are installed, in Skat 18K and 21K there are three heating elements, in 24K and 28K there are four. For each model, heating element blocks have different power.

Electric boiler connection: water circuit, cable
Connecting a Protherm electric boiler
1. Like most modern wall-mounted heating devices, all connectors for connecting the boiler are located at the bottom of the housing. This is done to save space in the room in which the electric boiler is installed.
2. The heating water circuit is connected using two threaded fittings with a diameter of 3/4″. On the left is the return line (coolant inlet to the boiler), on the right is the direct line (output).
3. Nearby are located: overflow for the safety valve, drain valve, as well as connectors for connection electric cable different sections. You can monitor the pressure in the heating system using the readings of the pressure gauge, which is also located in the lower part of the device body.
Electric boilers Proterm Skat: technical characteristics, dimensions
Proterm boilers have fairly compact dimensions of 410 x 740 x 310 mm, which allows them to fit harmoniously into the interior even completely small kitchen or boiler room. We look at the remaining technical characteristics in the table.
Technical characteristics of Proterm electric boilers
Errors and malfunctions of the Proterm electric boiler: methods for troubleshooting problems
1. Error code F00, F10, F13, F19.
These codes tell us that the NTS temperature sensor is faulty. It may need to be replaced or the electronic board replaced. But first check that the cable connections are working properly.
2. Error F20.
The emergency temperature limiter sensor or thermal fuse is faulty. Try to short-circuit them one by one. If the boiler turns off again, replace the faulty element.
3. Error F22.
This error indicates a “dry” start of the electric boiler. Add water pressure in the system, it should be at least 0.6 Bar. There may also be air present in pipes and radiators.
4. Error code F41 and F55. The relay or contactor is stuck. Check these parts for defects.
5. Error F63. No communication with EEPROM. Reset settings to factory defaults.
6. Errors F73 and F74.
Errors under these codes indicate problems with the water pressure sensor. You need to check the contacts or replace the sensor itself.
7. Errors F85 and F86. Freezing of water in the electric boiler itself (F85) or in the indirect heating boiler (F86).
