first, a charcoal fire in bottom tray, then a pan filled with hot (boiled) water above it, then the meat on top tray, then keep lid on a long time (hours) without peeking and remember to keep charcoal topped off. you should also soak hardwood hickory sticks in water for a day or 2 and wrap in aluminum foil with small holes punched through and place on top of charcoal to provide smoke. usually a large chicken is done in about 4 hours.

Dip wood chips/chunks in boiling hot water for a few minutes if you're in a hurry or allow to to soak in tap water for about an hour if you have plenty of time. Either way, place the soaked chips around and under the heating element at the bottom. Don't throw out the water; heat it up and pour it in the water pan. Heating it up to boil will give your smoker a good head start. I've been doing that on my char-broil smoker for years.
