How to use the wall-hung boiler in Dong Qing (the use of the wall-hung boiler in Dong Qing)

1. Gas-fired wall-hung boiler is a device integrating water collection, gas and electricity, which can be heated independently and provide domestic hot water at the same time. In order to ensure the normal use of gas wall-hung boilers, water, gas and electricity are indispensable.

2. Water: users should check whether the water pressure is between 1- 1.2Pa before use. In actual use, because there is some air in the system, when the boiler is running, the air in the system will be continuously discharged from the exhaust valve in the boiler, and the boiler pressure will drop irregularly; However, it is normal that the water in the system expands when heated, and the water pressure will rise, and then it will drop after cooling. As long as the water pressure of the boiler is kept between 0.5- 1.5 bar.

3. Gas: When the boiler is started, if no flame is detected, it will automatically enter the protection state, and the performance mode is that the red fault indicator lights up and gives an alarm. The reason for this phenomenon is that natural gas has been or is being interrupted. At this time, it is necessary to check whether the natural gas at home is unblocked. After ensuring the smooth flow of natural gas, manually reset the boiler until the red indicator light goes out.

4. Electrification: If the indicator light on the boiler is not on, it proves that the boiler is not electrified. At this time, you can plug in the power supply and electrify it.

5. Safety: First of all, the suction and exhaust of the flue must be unblocked, and the suction and exhaust ports of the boiler flue should extend out of the window, and it is not allowed to be closed indoors or use single-core pipes; Secondly, when the boiler is working, don't touch the heating, hot water outlet pipe or smoke pipe at the bottom to avoid burns; Finally, be sure to do a good job of antifreeze protection. If the heating system is full of water, the boiler must be prevented from freezing to prevent the equipment from working.

6. Water saving: There is cold water in the pipe between the boiler and the faucet. When the tap is turned on until the hot water flows out, the boiler will not produce hot water for about 6 seconds. Therefore, it is not advisable to turn the hot water tap to the maximum during this time. You should turn on the small water first, and then turn on the big water after the hot water comes out.

7, solar terms: when going to work during the day, the temperature of the boiler should be adjusted to the lowest. At this time, the boiler is in an anti-freezing state, the system water temperature is maintained between 35 and 40 degrees, and the overall indoor temperature is about 8- 14 degrees; If some rooms are not used for a long time, the valve of this room can be closed separately; If no one is at home for a long time, it is best to shut down the system and drain the water in the system to prevent freezing.
