I wouldn't worry about making the unit air tight, however. In fact, I often wonder if the "smokestack mod" isn't counterproductive if you're gonna use wood. From what I have read, one of the big differences between the "professional" offsets and the backyard units is the way that the draft and the air path combine to keep the smoke from a wood fire moving along briskly and cleanly </div></BLOCKQUOTE>
This is what is a little confusing to me. I was always told to leave the top damper open on a WSM, and leave it open on an offset. However, on the BGE I hear alot about people closing it to retain heat. On the Chargriller, if the stack is always open and the firebox damper is open, you should get good airflow, even if you have to close the firebox damper to keep temps down right?
Whether I'm using charcoal, lump, or wood, for the most part coals are coals. Won't they burn at whatever rate the oxygen supply will allow?
