I bought one of these right after Christmas and seasoned it this past Saturday. After it was seasoned I went ahead and played around with the smoker a bit. I turned the knobs all the way down and the lowest I could get it was 350 degrees. I realize that there was no water in the pan and that will affect it some. I've googled and some people say that the thermometer is garbage and to get a new one. What else can be done to get the temp around the 225/250 mark? Would changing the amount of propane going in affect the temp? Thanks for the advice.
