Dual Function Gas Wall Hung Boiler Home 20kw Gas or PLG Combi Boiler
The role of the main board: It is used to control the start and stop of the HVAC equipment, and constant temperature of the system.
The function of the gas valve is to ensure the normal combustion of the boiler. In a certain range of gas pressure, make the boiler stable combustion and can automatically adjust the gas supply according to the requirements of the boiler heat output, in order to realize the automatic shutdown of the boiler and gas proportion regulation.
The function of water flow switch: detect the amount of tap water through, under certain conditions, make the boiler switch to domestic hot water mode.
The role of the air pressure switch: The air pressure switch is mainly responsible for the safety protection in the wall mounted furnace system. It is divided into two chambers by a valve inside, and the two chambers on both sides of the valve are respectively connected with two pressure measuring tubes. By comparing the pressure obtained by the pressure measuring tube, it can detect whether the smoke exhaust system is normal.
The role of water pressure switch: In order to ensure the normal operation of the heating system, the system is filled with water, and maintain a certain pressure. The water shortage protection can be achieved by detecting the system pressure through the water pressure switch.

PRODUCT DISPLAY
The system connection and water injection connection are performed in the following steps
1, loosen the pump automatic exhaust valve and the system body heating water distributor or radiator exhaust valve.
2. Open the water refill valve and system water supply valve of gas heating hot water furnace and close the water outlet valve of sanitary hot water.
3. When the pressure of the heating system reaches 0.1MPa (the pressure gauge shows 1.0bar), close the water refill valve of the gas heating hot water furnace.
4, In order to discharge the air in the pump as soon as possible, you can start the circulating water pump repeatedly. There is air in the system , which will cause noise and affect the normal operation of the system. Close the exhaust valve of the water system when it has discharged water.
