A corkscrew-like rod that feeds pellets through a tube from the pellet hopper to the firepot. Auger Drive Motor - The motor that turns the auger.

The porcelain-coated steel grate is the non-stick, easy-to-maintain surface upon which your food rests while cooking.

The microprocessor circuitry and control settings that regulate the auger motor to stop and start the auger. There are two types of controllers. The Digital Thermostat Control allows you to select a specific temperature and monitor the grill's internal temperature via the LED readout. The manual control has three temperature settings; Smoke, Medium, and High.

Blows fresh air into the firepot through small holes in the cylindrical firepot wall.

Located in the heart of the grill, below the cooking area. This is where the pellets are burned, as the fire is fueled with hardwood cooking pellets and fresh air.

The galvanized bucket into which excess grease drains from out of the grill and away from the fire and your food.

The angled piece of steel that extends from one side of the grill to the other, and extends almost all the way from front to rear. Its two purposes are to drain grease out of the grill, and also to serve as the secondary point of heat diffusion, forcing hot air through the very front and rear of the cooking area. We recommend that you line this pan with heavy-duty foil for quick and easy cleanup when needed.

The heavy-gauge piece of angled steel that fits directly over the firepot to act as the primary heat diffusion point.

This refers to the entire modular assembly that attaches and extends into the main body of the grill during the easy assembly process on the BBQ070, BBQ07E and BBQ075.

A small heating element at the bottom of the firepot that glows red-hot for a the first four minutes of operation - just long enough to ignite the pellets.

Hardwood pellets are stored in the pellet hopper. The hopper is situated to the side or front of the cooking area, depending on the model.

A precision temperature sensor that measures the temperature inside the cooking chamber of a Traeger Barbecue. As the temperature inside the cooking chamber changes, so does the resistance created by the RTD. The circuitry within the Traeger Digital Thermostat Control monitors these changes and will activate the auger motor when the temperature drops below the selected setting.

Hot, smoky air exits the cooking chamber through the smokestack or vent. The vent is designed to look like a smokestack, a subtle slot on the back of the unit or even the snout of a pig, depending on the model of grill.
