Keep the water pan full and clean, dump it out getting rid of the grease and re-fill every two hours or so. I usually start out with warm water from the tap but if the temperature runs away, fill with cool water. Use a full pan, not a shallow fill.
I keep my two side vents at 50% and the top one all the way open. Mine is sheltered if that makes any difference. When it is windy, it definitely is an improvement.
I moved the wood box 1 inch lower by drilling new holes in the sides. Use large chunks of wood, not chips, they will last longer and give more even smoke.
