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

Where is the corn puffing, in the hopper? Before you put it in hopper? Or is it in the burn pot? Could you take a pic of the puffed corn blocking the chute and post it here?

Welcome to the forum, sounds like wet corn to me. The only reason corn would puff is moisture. For it to puff in the feed chute means you have heat going in there that shouldn't be. Is your hopper seal good?
Like AC said put up some pics showing the puffing. Put some corn in a pan on your kitchen stove turn the heat on med-low, does it puff? If so it's way to wet. You probably should be getting a dirty burn with it and that would make you think it's an air problem, which in a way it is but I doubt you can adjust it enough to burn it properly.

I agree... moisture

Are you burning with stir pot or clinker pot? No headaches for me with a clinker pot
