What key feature of the Traeger Ironwood helps prevent fire from entering the pellet hopper?

The key feature of the Traeger Ironwood that helps prevent fire from entering the pellet hopper is indeed that both the design of the auger and the built-in flame sensor work in conjunction to enhance safety. The design of the auger, which is higher than the firepot and offset, ensures that the flow of pellets is controlled, minimizing the risk of direct ignition from flames in the firepot. This design allows pellets to slide down into the firepot without the danger of creating a direct path for flames back into the hopper.

Additionally, the built-in flame sensor acts as a critical safety measure; it monitors for any flames that might inadvertently reach the hopper area. If a flame is detected, the sensor will automatically shut down the grill, preventing potential fires from spreading. Together, these features provide a robust safety system that ensures safe operation of the grill.
