Safety Information
Always ensure your grill is completely cool and disconnected from its fuel source before attempting any installation or maintenance. Wear appropriate protective gloves to prevent cuts or burns.
Setup and Installation
- Preparation: Ensure your grill is turned off, the gas supply is shut off, and the grill is completely cool. Open the grill lid.
- Remove Grates: Carefully lift and remove the cooking grates from your grill. Set them aside on a clean, stable surface.
- Access Burners: Locate the existing heat tents or burner covers. If present, carefully remove them. Note their orientation for future reference if they are being replaced.
- Position Flav-R-Wave: Place the new Broil King Flav-R-Wave Heat Tent directly over the grill burners. Ensure it sits securely and covers the burners adequately. The wavy side should face upwards.
- Replace Grates: Once all Flav-R-Wave heat tents are in place, carefully return the cooking grates to their original positions.

Operating Principles
The Flav-R-Wave system works by creating a large surface area directly above the grill burners. When food drippings fall onto the hot stainless steel, they instantly vaporize, creating smoke and steam that infuse your food with a rich, authentic barbecue flavor. This process also protects the burners from direct exposure to drippings, extending their lifespan and reducing flare-ups.
