How do I cure my smoker before first use?

Before first use, remove the water pan and lightly coat all interior surfaces with vegetable oil or cooking spray, avoiding the charcoal pan. Then light the charcoal, close the dome lid once fumes have burned off, and allow the temperature to reach the 'Ideal' range on the heat indicator, maintaining it for two hours before allowing the smoker to cool completely. Do not scrape or rub the exterior during the curing process, and cure the smoker periodically throughout the year to protect against rust. (Page 2)
