Hi. I have a gas smoker(upright). Yesterday the gas element pretty much fell off the bottom. Due to rust and corrosion. I dont have the money to buy a new gas smoker right now was wondering if I could use mine converted to a charcoal smoker. There is a big hole on the bottom where the gas element was. Would this be used for draw or should I cover it up? Was thinking of using aluminum pan for charcoal and wood would this work? Thanks for the help!!!
