I have new smoker and I have noticed there are gaps around the doors to the fire area and the level above it, is this ok or do I need to seal them somehow?
This is a great post about mods to a similar smoker to yours. http://home.comcast.net/~day_trippr/smoker_mods.htm Search on ebay for nomex gasket, you should get various returns for adhesive foam gasket you can stick round doors etc. From the US but shipping isn't too bad.
