I have had a 6041 for 3 yrs now and have had more than my share of headaches and cold nights. I have finally got my hands on some cheaper corn which throws great heat, but my dilemma now is that the corn almost seems to puff to about three times the size which the gets in the drop chute and plugs it. I can clean it out easy enough, but when I am not home it scares me that it is going to back up into the hopper. I am sensing a draft problem, but not sure where to start. I have found that on sunny warm days when the stove isn't running......I love it the most. Thanks in Advance... Mike
