Green Mountain Grills
A motor turns the auger that 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 airflow 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 onboard computer 10 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 the Green Mountain Grill support page for more information on heat shield setup and configuration.
