Pellet grill leaks smoke heavily from the lid and side seams instead of mainly from the chimney.

Safety first: Ensure the grill is cool before adjusting hinges or seals.

• Inspect gasket: Open the lid and examine the gasket around the cook chamber opening. Replace if it is cracked, flattened, or missing sections.
• Check lid alignment: Close the lid and look for uneven gaps. Adjust hinge bolts to center the lid over the opening.
• Tighten hardware: Tighten hinge and handle screws to ensure the lid closes firmly.
• Install new gasket: Clean the sealing surface with a degreaser, then apply a Rösle-compatible high-temperature gasket per instructions.
