Operating Instructions
Pre-heating the Grill
- Open the grill lid.
- Turn on the gas supply at the LP tank.
- Turn the main burner control knobs to the HIGH position.

Grilling Techniques
- Direct Grilling: For searing and cooking smaller items, use direct heat by placing food directly over lit burners.
- Indirect Grilling: For larger cuts of meat or delicate items, turn off the burner(s) directly under the food and cook with indirect heat from adjacent lit burners.
- Sear Station: The dedicated sear station creates an intense heat zone for quickly adding sear marks and locking in juices on meats.
- Side Burner: Use the integrated side burner to simmer sauces, sauté vegetables, or prepare side dishes while the main grilling area is in use.
