Hi guys I have a harman p68 stove and the other night I turned it on to heat our basement while we were down there and it burned a full bag of pellets in 8 hours. I turned the stove down to the lowest setting in room temp mode. The next night I did the same in stove mode and it burned through a bag in roughly the same time. Both times the stove was on its lowest setting. Any idea why it is burning so much? And what I can do to get it to burn less?
