Your grill comes mostly pre-assembled. Attach any remaining components such as the handle and base stand as per the included quick start guide. Ensure all parts are securely fastened before proceeding.

4.2 Initial Burn-In

Before first use, perform an initial burn-in to season the grill and burn off any manufacturing oils. Load the pellet hopper, set the temperature to 500°F, and let it run for at least 30-45 minutes. This process is crucial for optimal performance and flavor.

4.3 Pellet Loading

Open the pellet hopper lid and fill it with your desired wood pellets. The hopper has a 4LB capacity. Ensure the pellets are dry and free from debris.
