Hot Water Heater pulsing May 04, 2022, 09:22:40 am Our hot water heater ignites fine and continues to run, but it occasionally will lose propane or ignition and for less than a second pause and reignite. All other propane appliances run normally. This has been going on for a few months and I have been unable to determine the source of the problem. Suggestions would be appreciated.
Re: Hot Water Heater pulsing Reply #1 – May 04, 2022, 11:01:04 am If you know anything about propane burners, check the flame sensor and make sure it is clean. Also check and make sure you don't have too much air. You would see a very crisp blue flame, maybe lifting off the burner. You also don't want to see a very lazy yellow tipped flame, this will create soot. Mess with these only if you know about propane burners. The flame sensor will have a wire attached to it, it might also double as your spark igniter. The flame area on these need to be clean. I don't have any visual to help you out, sorry.Jon
Re: Hot Water Heater pulsing Reply #2 – May 05, 2022, 07:38:09 am Thanks for advice. Mothership said even though flame was blue it could be spider webs (I previously blew out tube) or an air mixture. I hope to apply all suggestions and hopefully have a solution.
Re: Hot Water Heater pulsing Reply #3 – May 05, 2022, 09:55:32 am If there is too much air allowing the flame to blow out, the flame will also be louder, so adjusting for a lower noise level while keeping the flame blue usually works well. Adjustment is usually done by loosening a small setscrew on the side of the burner tube, sliding the tube to adjust the flame, then re-tightening.Steve 1 Likes
