Grease fire in cook chamber, flames under grates

Safety first: Do not use water on a grease fire. Turn off and unplug the grill. Keep the lid closed to starve the fire of oxygen. Use a Class B or K fire extinguisher if flames escape.

• After fire is out and grill is cool: Remove grates, drip tray, and diffuser. Scrape and clean all grease surfaces and channels.
• Remove foil obstructions: If you use foil on the drip tray, ensure it does not block grease flow to the drain.
• Regular maintenance: Clean the grease system frequently, especially before high-heat cooks.
