Gas wall-mounted stove is equipped with manual water injection/water supply valve. The switch button is usually located at the bottom. When the pressure of heating system drops below 1bar due to the evaporation of gas in water, the user should open the valve slowly to pressurize the system until the system pressure restores to the prescribed water pressure. Generally, the system should keep about 1bar at static room temperature. The water pressure should be maintained between 1 bar and 1.5 bar during the operation. Do not leave the site during the water replenishment process.
Check whether there is a leak in the heating system and make sure that the system is completely closed.
Turn off the gas wall-mounted furnace and cut off the total power supply of the gas wall-mounted furnace.
Clockwise tightening of water injection/replenishment valve for about a week;
Observe the water pressure gauge on the operation panel. When the water pressure gauge pointer is between 1bar and 1.5bar, the water injection/supplement valve handle should be rotated clockwise to close the water injection/supplement valve. After the completion of the water supplement, the water injection/supplement valve must be closed tightly, otherwise the gas wall hanging furnace will overpressure overflow. If the water pressure in the heating system is recharged to about 3bar carelessly, the pressure relief operation is needed.
Start-up operation of gas wall-mounted furnace.
How to prevent the wall-hanging furnace from freezing?
When encountering cold and frozen weather in winter, please keep water, electricity and ventilation when not using wall-hanging stove. When the outside temperature is too low, wall-hanging stove will automatically start anti-freezing function.
When the water temperature of wall-hanging furnace is below 8 degrees, the function of anti-freezing protection can be started only if the following four conditions are satisfied:
1) The wall-hanging furnace power supply is connected, and the power can not be cut off (or the plug can not be dialed);
2) Guarantee the normal supply of gas (gas meter battery is electrified and gas is sufficient, gas pressure is normal, gas valve can not be closed);
3) The water pressure of wall-hanging furnace is kept at 1-1.5 Bar (can be checked by pressure gauge of wall-hanging furnace itself);
4) The valve is opened and the circulation pipeline is connected.
5) Wall-hanging furnace is fault-free and can operate normally.
In a short time, there is no need to shut down the power supply, and in a long time, there is no need to use the gas wall-mounted furnace. Under the condition of possible icing, the water in the wall-mounted furnace, heating pipe and sanitary pipe must be discharged cleanly. Systematic evacuation is also required in the maintenance of wall-mounted stoves or in the maintenance of heating and sanitary water pipes.
Wall-hanging furnace is a precise heat source equipment which integrates water, electricity and gas. When using it, we should pay attention to the correct operation methods to ensure safe and stable operation.
