安全使用壁挂炉的方法和注意事项（Methods and precautions for safe use of wall hanging furnace） The domestic gas wall hanging furnace is a combination of water, electricity and gas, which can provide the advanced equipment for the life of hot water and independent heating, which is convenient and not affected by external factors. If the owner can use correctly, not only can increase the use efficiency of the wall hanging furnace, can prolong its service life, the main one is big save energy. About the water pressure User before use, first check the boiler water table pointer is within the scope of the regulations, instructions specified in the standard for 1-1.2 mpa water pressure, but in the process of actual use, due to the heating system and there is some air in the boiler, when boiler operation, the system of air from the exhaust valve discharge inside the boiler, the boiler pressure will drop irregular; In winter heating, the water in the heating system expands, the system water pressure rises, and the pressure drops after the water cooling, which is normal. The experiment shows that the water pressure in the wall furnace will not affect the normal use of the wall hanging furnace as long as it is kept between 0.5 and 1.5 bar. Water down in 0.5, may be the cause of living hot water hot and cold or normal boot, such as water pressure is higher than 1.5, pressure in heating system, if more than 3, the boiler safety valve will automatically drain, may cause unnecessary loss, under normal circumstances around one to two months to fill water at a time. Special reminder: after the system rehydrated, the boilers water supply switch must be turned off. The owner of the long-term business trip should close the water supply valve. It is recommended to add a drainage pipe to the safety valve of the boiler to avoid unnecessary loss when the boiler water pressure is too high. There is a red light on the boiler When the boiler starts, if the flame is not detected, it will automatically enter
