1. After the wall-mounted boiler is ignited, it will automatically turn off the flame. Possible main causes: no natural gas supply or temporary gas outage or need to purchase gas recharge or gas valve shut down. Specific solutions: Confirm that the natural gas supply is normal and smooth. 2, the system pressure is too low Possible main causes: gas in the wall-mounted boiler heating system or leakage in the heating system. Specific solution: After confirming that there is no leakage in the heating system, replenish the heating system: 1) Confirm that the tap water valve is in the open state, open the boiler fill valve to replenish water until the pressure is normal; 2) Close the boiler fill valve. 3, there is a sound of running water inside the radiator Possible main cause: air is left in the water pipe or radiator. Specific solution: You can open the air vent at the top of the heat dissipation and let the air inside out. Then adjust the water pressure of the wall-mounted boiler and ensure that the pressure is stable. This is done by the drain knob below the wall-mounted boiler. 4. The amount of sanitary hot water in the wall-mounted boiler becomes smaller Possible main causes: the faucet filter is blocked or the filter of the cold water inlet is blocked. The specific solution: the bellows of the cold water inlet can be removed and can be seen after cleaning. 5, not at room temperature The heat dissipation of the radiator is not enough: the radiator is greatly reduced, so that the heat radiated by the radiator is not enough to make up for the heat loss of the room. The wet room is not dry: continue to heat for a while while observing. 6, the heating system water pressure is frequently reduced Possible cause: If the equipment is normal, there may be a leak point in the entire heating system. Specific solutions: Ask the professional to analyze, inspect and repair the system. 7. The wall-mounted boiler stops working, a red light is flashing, and the water pressure indicator is also flashing. Possible main reason: the wall-mounted boiler system is short of water. Specific solution: Water is injected through the water injection knob located at the bottom of the wall-mounted boiler to make the water pressure between 1.5-2 bar. After operation, the wall-mounted boiler will automatically ignite. If frequent water injection is required, it is likely that the system is leaking. Please contact the after-sales service provider. 8, wall-mounted boiler heating has noise and slow heat Possible causes: The heating and returning water filter of the wall-mounted boiler is blocked or the heating pipeline is blocked. Specific solution: Disassemble the bellows after cleaning, but it is best to be cleaned by a professional after-sales service. 9, the temperature of domestic hot water fluctuates greatly Possible main causes: the tap water pressure is too low; the gas supply is unstable. Specific solution: increase the tap water pressure; add a pressure regulator to stabilize the air pressure. 10, wall-mounted boiler does not replenish water Possible main causes: the manual water supply valve is not open; the automatic water supply valve is not water; the automatic water supply valve is not energized. Specific solution: Open the manual water supply valve; confirm the automatic water supply valve filter and clean; confirm the main controller output. 11, hot water is not hot Possible main causes: gas pressure is too low; gas inlet pipe diameter is too small; hot water supply pipe is too long, heat loss is large in the middle; main heat exchanger carbon or scale is serious; hot water set temperature is low; heat The water flow is too large; the gas proportional valve is faulty; the controller is faulty and the sensor is faulty. Specific solutions: contact with the gas company; replace the appropriate intake pipe; reduce the hot water pipe; clean or replace the main heat exchanger; increase the hot water supply temperature setting; close the small hot water valve; replace the gas valve; replace the control Replace the sensor. 12, hot water is too hot Possible main causes: gas pressure is too high; the water pressure used by the user is too low; the hot water flow is too small; the inlet filter or the outlet is blocked; the hot water setting temperature is too high. Specific solution: contact with the gas company; contact the water company; install the mixing valve or booster valve; open the hot water inlet and outlet valves; clean the blockage; lower the hot water temperature setting Single Handle Basin Faucet,Single Cold Water Basin Tap,Single Tap Bathroom Faucet,Single Basin Faucet WENZHOU HUAGUAN SANITARY WARE CO,.LTD , https://www.wzhuaguan.com
