A motor turns the auger which feeds pellets into the firebox. There, a hot rod automatically ignites the pellets, and a combustion fan below keeps them burning. Vents vertically line the inside of the Firebox creating a circular air flow. A fan inside the Pellet Hopper maintains positive pressure which prevents burn-back in the auger tube. When met these two air flows create the ultimate wood burning fire and circulating pure hardwood smoke flavor.
The Heat Shield* that covers the Firebox distributes the heat to both sides of the grill and flows up into the convection-style grill chamber. A sensor mounted inside the grill sends data to the on-board computer ten times every second, and the controller adjusts the air and pellet flow to maintain the temperature you set.
*Heat Shield styles and positioning vary between the different grill models. View our support area for more information on heat shield setup and configuration.
