I called Tech Support about a problem I had with my smoker on the first day. After a nice young man called me back, we got to talking. It seems that one item that sometimes needs adjusting is the hot end. He said that it sometimes isn't installed into the fire pot the appropriate distance. I'm sorry, but I don't remember what he said. It might have been 3/8", but it might not. I didn't write it down in my manual like I should have. I'd suggest calling them, leaving your number with their IVR system for a call back, and then ask them how far into the fire box the hot end should be. Maybe it only needs adjusting.
