I have a USSC 6039 and doesn’t seem to be putting out much heat. Only keeping my basement at about 70. Not a full basement, first floor only about 60. My flame doesn’t seem big enough. Maybe an inch above the fire pot but under the auger. Should it be higher? The flame looks good. FAK hooked up. Freeze plug in holes behind “brick”. The flame dance nice, just feel like it could definitely be throwing more heat. My house is only about 1300 square ft but barely keeps the basement at 70. Any tips on feed rates and air rates?!
