Ok people, so I have gotten a free smoker from my parents and I need to make sure I have this thing setup right. I have a Brinkmans Gourmet and so far from what I have gathered from this site is that. I need to put lava rock under the element? I think I read somewhere that the the wood chips go on the lava rock but not toughing the element. Is that correct? Either water or sand in the pan? (I have gathered there is a big debate on this, I just haven't read up on it yet.) These normally operate in the 250 degrees range pending weather? I won't be using an extension cord. It might be a good idea to do some mods to it? Also there are 2 rack settings, what would each of these be for? You guys can add anything to help me out as I have never smoked anything or used a smoker before. I appreciate all your guys help in advance. BTW great site here.
