A motor turns the auger which feeds pellets into the firebox. There, a heat rod automatically ignites the pellets and a variable speed fan keeps them burning. The Venturi-style firebox is lined with vertical vents creating a burn pot cyclone of air flow for maximum heat and complete combustion of the pellets with minimal waste.

The heat shield that covers the firebox distributes the heat to both sides of the grill, causing it to flow up into the convection-style grill chamber. A sensor mounted inside the grill sends data to the on-board computer 10 times every second, and the controller adjusts the air and pellet flow to maintain the temperature you set.
