I'm burning mostly oak and some maple, a bit of ash. All 1-1/2 to 2 years season. I'm trying to get it all cleaned up, They were full sized trash cans! I think its been overloaded and not cleaned since I bought the house in october, not sure how the last guy maintained it. I've got the high setpoint as high as it will allow,( unless anyone knows how to allow it to go above 180) Would a creosote log help at all? I've also been told to check the FLA of the blower and make sure its not all gummed up.. its blowing air but is it at the right CFM. Possibly I have an air leak but I dont think so, it seems like the fire is choked wayyyy down until I open the door. I also want to make sure the chimney isn't plugged up some, it blows smoke but im not sure if its all plugged up. Any place I can get brushes easily?
