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 remove combustion products into the chimney with natural traction
. 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
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. The boiler expansion tank is designed for a heating system capacity of 95 liters.. In larger systems, another expansion tank should be installed membrane type
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 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.
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.
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, DHW system and gas supply with special.
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.
- Safety valve connection – 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 work on liquefied gas (propane), s calorific value
from 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 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 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;

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.

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. In case of freezing (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.

As expected good equipment from famous brand, Proterm electric boilers are housed in neat, compact housings. Thereby they can fit into any interior, even the most sophisticated ones. Case dimensions – height 740 mm, depth – 310 mm, width – 410 mm (dimensions are identical for the entire Skat model range). Inside we will find everything you need for the heating system to work:
- Circulation pump;
- Automatic air vent;
- Expansion tank 7 liters.
There is no need to worry about installing the piping - just connect the pipes and radiators, fill the system with coolant, after which you can start testing.
Models with a power of 6 kW and 9 kW can operate from both single-phase and three-phase networks. More powerful ones are three-phase. The equipment is not afraid of power surges and does not cause overloads on the network - a stepwise increase in power is provided here. The maximum current in the circuit when the heating elements are operating is up to 50 A. The maximum coolant pressure in the system is 3 atm, the temperature is up to +85 degrees.
When connecting Protherm electric heating boilers to the electrical network, you must ensure that the cross-section of the wires corresponds to the power consumption.

Protherm electric boilers are equipped with convenient control panels. They contain LED indicators and liquid crystal displays. Self-diagnosis systems are provided - error codes are displayed on built-in screens. For creating comfortable atmosphere thermostats are used. Safety systems include an overheating sensor, frost protection, a pressure sensor, a safety valve and an anti-blocking system for the circulation pump.
An interesting functionality is the ability to connect external storage boilers, which are purchased separately.
Popular models
The electric boiler Protherm Skat 9 KR 13 is the most popular. Used to heat rooms up to 90 square meters. m.
As we have already said, electric boilers from Protherm are represented by the only Skat line. Therefore, all equipment has similar characteristics, differing electrical power and current consumption - all other data is identical, down to dimensions and weight. As for the most popular models, they are designs with a power of 9 kW, 12 kW and 21 kW.
In addition, the Skat model range includes models with a power of 6 kW, 14 kW, 18 kW, 24 kW and 28 kW - the maximum heating area depends on the power (calculations must take into account heat loss and the possibility of connecting a boiler).
Instructions for use
When installing and configuring the device, you must follow safety regulations and use protective equipment. Boilers are installed in a dry place, away from flammable structures, emergency exits, air conditioners and other electrical appliances. Installation in places where water may enter the equipment is not allowed.. Also, operation in freezing areas is not allowed.
Mount the equipment on solid walls, taking into account the weight. Heating pipes must fit smoothly and without distortions. Connection to the electrical network is carried out using wires of suitable cross-section, directly to electrical panel, through additional RCD machines. For impact protection electric shock the equipment must be grounded. You also need to make sure that the supply voltage complies with the established standards. External components and modules are connected in accordance with the instructions.

Ideally, the installation should be carried out by certified specialists, but if you follow the instructions and follow the safety rules, nothing bad will happen.
During equipment operation, it is necessary to monitor the temperature in the system and respond to possible mistakes. If the equipment is working properly, users can only set the desired temperature. The temperature of the heating circuit and the temperature in the external storage boiler (if equipped) are selected using the buttons on the control panel - parameters and errors are monitored using the LCD display.
