An autonomous heating system provides savings on the heating agent, reducing installation costs. In order to reduce fuel costs and heating efficiency, it is advisable to connect the Proterm Gepard gas boiler. The products of the Slovak brand are distinguished by quality, reliability, a wide range of models and ease of installation.
Complete set and principle of operation of gas boilers Protherm Gepard
A standard wall-mounted unit with two circuits is completed with the main units, software and a hydrogroup. The main elements of the boiler are:
- expansion tank of membrane type;
- a sensor that monitors the parameters of water in pipes;
- hydraulic mechanisms;
- block with 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 safety valve for 3 atm .;
- pressure controller;
- stainless steel plate secondary boiler;
- automatic air vent;
- valve, switchable in 3 positions;
- pump for supplying liquid to the circuit;
- gas valve type SIT.
The system is controlled using an LCD monitor, where the main parameters are displayed. 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 up to 50 degrees) and "Underfloor heating".
Principle of operation
A two-circuit device with a turbine can be connected to heating and hot water systems. The water is heated by a plate heat exchanger. The combustion products are discharged through a coaxial chimney. The intake of oxygen for the combustion reaction is carried out by means of forced circulation.
The modulating gas burner allows you to select the flame power when heating water and heat carrier. At the moment of opening the valve for hot liquid, the power indicator increases and switches the mode. The operation parameters are set by the user. In the future, they can be changed automatically or adjusted mechanically.
For efficient heat transfer to a closed heating, a circulation pump is additionally connected.

Gas boiler installation rules
The use of boiler heaters is a closed system with a forced circulation type, operating to heat the room and hot water supply. When installing structures, it is required to comply with the manufacturer's technical regulations:
- The choice of the distance from the boiler to the surface. Wall-mounted models are removed 50 cm from the ceiling and 80 cm from the floor.
- Fastening a metal sheet 3 mm thick on a wall for equipment.
- Preparation of the electrical cable and the organization of the grounding line.
- Drilling holes for fasteners according to the mounting template.
- Connecting the complete threaded nipple to the gas pipeline.
- Checking the 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 shut-off valve and a non-return valve.
- Installation of a filter at the entrance to the DHW system.
- Installation of a gas meter, stabilizer and circuit breaker.
- Connecting electrical elements - conductors to plug terminals, plugs to the board socket.
- Fastening cables with clamps.
The device can only be commissioned by a specialist with a Protherm certificate.
User's manual
A user manual is supplied with the unit. The document contains the basic rules for the operation of the boiler:
- If a burning smell appears in the room, do not turn on the light, smoke, use the phone. The device is immediately disconnected from the network, and the boiler room is ventilated.
- There must be a place near the appliance for servicing. A gap of 30 cm is needed above and below the structure. 10 cm remains at the side and 60 cm near the front.
- With a long trip, valves for heating, hot water supply and gas supply are closed.
- The recommended heating medium pressure is from 1 to 2 bar.
- Explosive and flammable substances, paint and varnish products must not be stored near the boiler.
- To select the heating mode, press MODE. To go to "Summer" - the same button twice, to "Vacation" - three times.
- Water temperature parameters are set using the plus and minus keys.
- To set the temperature indicator of the heating main, you need to press MODE, and then - "plus" or "minus".
Do not use the device if the system is defrosting or the heating medium is leaking.
Major breakdowns
In case of device malfunctions, a code is displayed on the LCD display by which the error is recognized. The algorithm for working with it is presented in the instructions. Other common hardware failures include:
- breakdowns of pressure sensors, temperature, gas control valves;
- malfunction of the gas supply system or ionizing valve;
- chimney blockage - no air supply;
- stop in case of voltage drop in the network;
- closures - sensors of the water supply circuit, housing, pressure switch;
- the formation of air congestion;
- problems with software - the 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.
