Questions & Answers for Mr. Heater MH18B

Heater will light for a short time and then goes out will not stay lit any ideas to fix
Bill for model number Mh18b asked on 2022-10-21
Hello Bill, Thank you for writing. If the Pilot is too far from the flame, this can cause the pilot to go out and shut down the heater. We suggest checking the Pilot placement and move it closer to the flame if needed. The Pilot could also be worn out, in which case it needs to be replaced. We hope this solves your problem!
