I'm still getting used to my Perfect Flame smoker and I'm wondering how you all use your vents on your propane smokers. So far, I've kept the bottom vents closed as much as possible and the same with the top (though on mine, you can't get the top one more than 1/2 closed for some reason). I haven't used much wood chips so far so I'm not too worried about creosote buildup otherwise I should maybe keep the top full open. Also, I get alot of leakage around the top of the door - I've got some silicone that I can apply to close that gap. I'm dreaming up some mods to my smoker and I'd like to know if I'm going to want to use those bottom vents at some time.
