Just curious as to how some of you adjust the dampers to control heat... My new smoker grill has a chimney with the side smoker. Do I use the chimney damper to help control the heat or use it only for smoke control...? Or use both the chimney damper and the side pot damper...? Another ? is, if the smoke is backing up and coming out from under the lid am I getting enough flow through...? Or should I open the chimney farther...?
