Grill leaks heavy smoke from around the lid, hopper lid, or seams.

Safety first: Operate pellet grills only outdoors in well‑ventilated areas. Do not attempt to seal all leaks completely; some venting is normal.

• Step 1 – Inspect lid alignment: Close the main lid and check for gaps. Adjust hinges if possible to improve contact.
• Step 2 – Check gasket: If your Cuisinart model includes a lid gasket, inspect it for cracks, flattening, or missing sections. Replace with a high‑temperature gasket kit if worn.
• Step 3 – Tighten body bolts: Verify that all bolts holding the barrel and hopper to the frame are tight, which can improve sealing at seams.
• Step 4 – Hopper lid seal: Ensure the hopper lid closes fully. Replace any foam or rubber seal if it is damaged.
