Last year my Mother-In-Law bought me an electric smoker as a Christmas gift & that is what I have been doing all of my BBQ in. Well, this past weekend, my wife stopped at a garage sale & bought me a Char-Grill H20 unit. So, now I have to learn how to use it. It is my understanding that I would be putting lump charcoal in the coal pan & get the fire going, then I would wrap my wood chips up in a "pouch" of aluminum foil (poke a few hole in the foil) & place that on top of the charcoal. Am I on the right track? Also, for a 12 hour smoke I assume that I am going to have to add fuel on a fairly regular basis in order to keep my temperature up. Any insight that anybody can offer would be greatly appreciated.
