What type of charcoal or wood should I use, and what should I avoid?

Use only high-grade plain charcoal or a charcoal/wood mixture — never use pre-treated charcoal that has been treated with lighter fluid. Do not use gasoline, kerosene, or alcohol for lighting charcoal, as these can cause an explosion leading to severe bodily injury. For flavoring wood, avoid resinous woods such as pine, as they will produce an unpleasant taste. (Page 2)
