Our firepot is the latest in breakthrough technology for gravity fed pellet systems. This firepot maintains a correct amount of air volume passing through the fuel, allowing the fuel to take on two different combustion areas. This helps minimize the amount of ash content and maximize the combustion efficiency of the product. The bottom of the firepot is retractable via a pull out rod attached to a spring handle on the outside of the grill or heater for easy maintenance. Simply pull the rod and swipe the ash, dumping it into the ash pan. Empty the ash pan at your convenience in a non-combustible container.
