Smoke leaking heavily from lid edges and body seams instead of primarily from chimney.

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

• Check lid alignment: Open and close the lid to see if it contacts evenly. Adjust hinge bolts to center the lid.
• Inspect gasket: If your GMG model has a lid gasket, check for gaps, burns, or missing sections. Replace with OEM gasket if damaged.
• Tighten body screws: Tighten any loose screws around the cook chamber and lid hinges.
• Address warping: If the lid or body is significantly warped, contact GMG support for replacement options.
