What is the reason why the hot and cold water heater cannot fire?

If the cold water heater fails to ignite in cold weather, it may be that the air pressure in the air-conditioning bottle decreases due to the change in weather, causing difficulty in ignition or failure to ignite. It may also be that the pressure reducing valve is improperly adjusted, causing the air pressure to be too low to ignite in cold weather. Specific solution: The cylinder gas pressure is reduced due to simple cold air and the gas cylinder cannot ignite. You can sit a basin at the bottom of the cylinder and pour some hot water into it. This can solve the problem of non-ignition of the natural gas water heater. If the fire fails to ignite in cold weather due to improper adjustment of the pressure reducing valve, you only need to open the air valve half a turn more, and at the same time, adjust the upper adjustment button of the pressure reducing valve to the plus sign or clockwise. lock up. This answer applies to Haier EC6001-GC and Haier ES60H-HC3(E) brand water heater models.
