Morning all As I posted earlier, I converted my wood/charcoal burner to propane http://www.smokingmeatforums.com/f/92/smoking-supplies-equipment I'm very happy with the conversion--heat and temp stability is great. What is not great is the smoke flow from my mailbox mod over the meat and out the chimney. The smoke enters the CC just fine then, instead of flowing around my meat and out the exhaust, it is drawn into the firebox and gets burned up. I do have some smoke around the meat, but none coming out the chimney. It is obviously a drafting problem, but I'm not sure how to correct it. I keep the vents into the firebox wide open, and the chimney (which I have extended by 4" as a test) is wide open. I plan to put a 12" extension on the chimney and see what that will do. Perhaps I need a deflector plate between the firebox and the CC?? My last cook, I even tried putting the AMNPS in the CC between the firebox and the meat. Same result--smoke headed toward the firebox--but I did get more onto the meat. When I took the meat off and turned off the burner, I had TBS coming out the chimney within 1 minute. I'm open to any and all ideas, thoughts, suggestions, etc. The following 2 pics are of the CC and the burner location in the firebox.
