This morning I put together my smoker I bought from Bass Pro. My model is the 20051313. What I am curious about is, is this normal: I am very inexperience in this smoker with propane. Is this is how it is supposed to look at the brass piece inserted into the stainless steel. Seems like too much of a gap. I am going to season tomorrow, but I want to make sure it is safe to operate. Please help.
