The parking heater has been on for a long time. How can I make it work?

It is wrong to leave the parking heater unused for a long time!!!

How should the heater be maintained when not in use?

Outside the service life of the heater, the heater should be turned on for about 10 minutes every month.

If the parking heater is not used for a long time, it may fail to start and fail to ignite. If it is idle for a long time, check whether the air inlet system, air outlet system, combustion air system and exhaust system of the heater are normal, and clean them if necessary When the heater is not used in the warm season, please start it regularly for 4-5 times, each time for about 5 minutes, to ensure that the heater operates normally in the next use
