Autonomous heating system provides savings on the coolant, reducing installation costs. In order to reduce fuel costs and heating efficiency, it is advisable to connect a gas boiler Proterm Cheetah. Products of the Slovak brand are distinguished by quality, reliability, an extensive model range and ease of installation.
Options and operating principle of gas boilers Protherm Gepard
A standard wall-mounted unit with two circuits is equipped with the main components, software and hydro group. The main elements of the boiler include:
- expansion capacity of the membrane type;
- a sensor that monitors the parameters of water in the pipes;
- hydraulic mechanisms;
- block with an electronic board;
- burner with electric ignition system
- electrode protection;
- boiler;
- turbine for turbocharged models;
- coaxial pipe and distribution adapter.
The hydrogroup is represented by:
- protective fuse-valve at 3 atm .;
- pressure controller;
- stainless steel plate secondary boiler;
- automatic air vent;
- valve switchable in 3 positions;
- a pump for supplying fluid to the circuit;
- gas valve type SIT.
The system is controlled using the LCD monitor, which displays the main parameters. Built-in diagnostics determine the error code. The branded software allows you to operate the heat-power device in the “Eco” modes (heating the coolant to 50 degrees) and “Warm floor”.
Principle of operation
A dual-circuit apparatus with a turbine can be connected to heating and domestic hot water systems. The water is heated by a plate heat exchanger. Fuel combustion products are discharged through a coaxial chimney. The oxygen intake for the combustion reaction is carried out through forced circulation.
The gas burner with modulation allows you to choose the power of the flame when heating water and coolant. At the moment of opening the valve for hot liquid, the power indicator increases and switches the mode. Work parameters are set by the user. In the future, they can be changed automatically or adjusted mechanically.
For effective heat transfer to the closed heating, an additional circulation pump is additionally connected.

Rules for installing a gas boiler
The use of boiler heaters is a closed system with a forced type of circulation, which works to heat the room and domestic hot water. When installing structures, it is required to comply with the manufacturer's technical regulations:
- Choosing the distance from the boiler to the surface. Wall models are removed 50 cm from the ceiling and 80 cm from the floor.
- Mounting a 3 mm thick metal sheet on a wall for equipment.
- Electrical cable preparation and grounding line organization.
- Drilling holes for fasteners according to the mounting template.
- Connection of a complete threaded fitting to the gas pipeline.
- Checking the amount of volume of the built-in tank. If there is a shortage, an additional tank is installed next to the boiler.
- Installation of a non-return valve in case of connecting a second tank.
- Flushing the line and removing air from it.
- Connection to cold water pipes of a stopcock and non-return valve.
- Installation of the filter at the entrance to the domestic hot water system.
- Installation of a gas meter, stabilizer and circuit breaker.
- Connection of electrical elements - cores in plug-in terminals, plug in the socket of the board.
- Cable fastening with clamps.
Commissioning of the device is carried out only by a specialist with a Protherm certificate.
User manual
A user manual is supplied with the unit. The document contains the basic rules for the operation of the boiler:
- If there is a smell of burning in the room, you can not turn on the light, smoke, use the phone. The device immediately turns off the network, and the boiler room is aired.
- There should be a place for servicing near the appliance. A clearance of 30 cm is needed above and below the structure. 10 cm remains on the side and 60 cm near the front.
- With a long departure, the valves for heating, domestic hot water and gas supply are shut off.
- Recommended coolant pressure is from 1 to 2 bar.
- Explosive and flammable substances, paint products should not be stored near the boiler.
- To select the heating mode, press MODE. To go to "Summer" - the same button twice, in the "Vacation" - three times.
- Water temperature parameters are set using the plus and minus keys.
- To set the temperature indicator of the heating main, you will need to press MODE, and then “plus” or “minus”.
Operation of the device is prohibited during defrosting of the system or leakage of coolant.
Major breakdowns
In case of device malfunctions, a code is displayed on the LCD display, by which an error is recognized. The algorithm for working with it is presented in the instructions. Other common equipment failures include:
- breakdown of pressure sensors, temperature, gas control valves;
- malfunction of the gas supply system or ionizing valve;
- chimney blocking - no air supply;
- stop when the voltage drops in the network;
- short circuits - sensors of the water supply circuit, housing, pressure switch;
- formation of air jams;
- problems with software - water is heated, but the circuit is not heated.
Error codes can be eliminated according to the manufacturer's recommendations. Defective parts will need repair.
