Moved into this house just before last winter, first pellet stove experience, Harman Advance that previous owner says she had cleaned yearly and seems in great shape. I did not have this cleaned after last season and regret that now. Had a few times last season of not lighting on first cycle, but within a month this season will never light on first cycle, usually does on second or third. Seems to be getting worse over time. I have tried scraping burn pot, vacuuming everything I can reach front of stove. Burn pot seems to get very hot, plenty of pellets getting fed. Once it lights it is fine from then on (but I turn it off at night and when I am at work during day). I have put in calls to local pellet stove businesses but it is mid season so I assume it might be spring before I hear back. Would welcome any tips and, since it still does light eventually, is there a way to turn off the pellet feed while waiting, so that unburned pellets don't get dumped into ash pan during the process? I had once instance of house filling with smoke at night from smoldering pellets in ash pan.


stove and pipe needs cleaned. Dont use the stove until you do this. I attached a youtube video. It is probably plugged up behind the rear covers inside the stove
