Specific use steps of Dong Qing boiler

Using Dong Qing boiler, water, gas and electricity are essential.

First: 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, the air in the system will be continuously discharged from the exhaust valve in the boiler when the boiler is running.

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.

Second: gas: if no flame is detected when the boiler is started, 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.

Third: Power on: If the indicator light on the boiler is not on, it proves that the boiler is not powered on. At this time, plug in the power supply and power on.

Matters needing attention in using Dong Qing boiler:

Safety: first of all, ensure the smooth suction and exhaust of the flue. The suction and exhaust ports of the boiler flue should extend out of the window, and it is not allowed to close or use single-core pipes indoors.

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.

Water saving: There is cold water in the pipe between the boiler and the faucet. In the process of turning on the faucet until the hot water flows out, the boiler will not produce hot water for about 6 seconds, so it is not advisable to turn on the hot water faucet 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.

Solar terms: When you go to work during the day, you should adjust the temperature of the boiler to the lowest. At this time, the boiler is in an anti-freezing state, the system water temperature is maintained at 35-40 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.
