Main Tube Burner Conversion
Tools required:
Phillips Head Screwdriver (+)
6mm Nut Driver
Steps
：
1. Remove the main tube burners by removing the screw securing the burners near the back wall of the firebox
and the screws near the front of the firebox that secure the igniter brackets to the burners. Gently lift the burners
up and out.
2. Locate and remove the LP orifice at the end of each valve with a nut driver. The main burner NG orifices are
located behind the LP orifices, so no additional orifices need to be installed. CAUTION: The NG orifice is easily
loosened or even removed together with the LP orifice when the LP orifice is being unscrewed. Make sure the
NG orifices are securely installed on the main burner valves after the LP orifices are removed.
