gas wall-mounted boiler : heating system is normal, detection system pressure is normal, water pump is working, water flow switch or water flow sensor Turn on, output water flow signal, clean before the fan enters, detect that the wind pressure is normal, all safety devices are normal, ignite (the fan enters low-speed operation or enters low-fire ignition), ignites fire, ion induction flame, normal combustion, the fan enters normal speed, reaches the set temperature, flameout, cleans after the fan enters, and the water pump delays shutdown.

Advantages of wall-mounted boiler :
1. Energy saving, environmental protection, cost saving
Users who use wall-mounted boilers avoid the problems of difficult adjustment and energy waste in collective heating. The heating temperature can be flexibly adjusted as needed. Some gas wall-mounted boilers can be connected to radiators and floor heating systems, which can save 20% of energy compared with most heating methods. When no one is at home, the indoor temperature setting can be lowered or turned off to save unnecessary heat loss.
2. Easy and flexible control
wall-mounted boiler heating is a radiation heat dissipation method, and its dissipation points are located in every corner of the room. Users can flexibly adjust the temperature of the wall-mounted boiler and realize zone temperature control, allowing users to freely set the room temperature and start and stop time. After the wall-hung boiler is turned off, the room will still remain within a certain warm range for a long time.
3. Heating and comfort
wall-mounted boiler gas heating system uses a bottom-up method to circulate heat, giving people a gradually warmer feeling from feet to head. It is not as dry as water heating.

Instructions for use of the wall-hung boiler:
1. When turning on the wall-hung boiler, you should pay attention to whether the water pressure of the wall-hung boiler is between 0.5 and 1.5bar. If so, you can use it with confidence. If not, you need to adjust it in time to avoid damage to the wall-hung boiler.
2. After the wall-hung boiler is replenished, the water replenishment switch of the wall-hung boiler needs to be turned off. If the wall-hung boiler does not need to be used for several months, the water supply valve of the wall-hung boiler must be closed, drain the water inside, and turn off the power.

3. In winter, you can use the heating function of the wall-mounted boiler to improve living comfort, but you must pay attention to the anti-freezing measures of the wall-mounted boiler. You can add antifreeze and ensure the uninterrupted supply of water and electricity.
4. When using a wall-hung boiler, it is necessary to regularly check whether there are any abnormalities in the wall-hung boiler and whether the gas transmission hose is damaged, so that it can be repaired in time, so as to bring safety to the normal home of the residents.
