I am new to this pellet stove stuff. I was given an American Harvest 6100 stove. My Dad installed it for one season back in 2008 and did not like it. Anyway it has taken me a while and about 4 hours of phone time with USSC but the stove is working pretty good. Mostly the front seal was creating huge problems. After that was replaced the fire is good now. But the issue is the fire box will get up to as high as 760 degrees but the bonnet does not put out anything more then 95. Not sure what is wrong. The exhaust vent is about 240 -260. USSC says that is fine. I am not sure if there is a heat exchange that might need cleaned of what. I need help. It is using 4 bags of pellets a day but does not put out much heat from the bonnet. Thanks
