PILOT SCREW

PILOT BURNER ADJUSTMENT

Adjust the pilot screw to provide properly sized flame. Turn in a clockwise direction to reduce the gas flow.

VENTURI ADJUSTMENT

Remove the 2 screws securing the control panel plate. To access the venturi, remove the air housing cover plate, held on with 2 screws. Take care not to damage the gasket. Natural gas and propane models have air shutters set fully open. Closing the air shutter will cause a more yellow flame, but can lead to carboning. The flame may not appear yel- low immediately; allow 15 to 30 minutes for the final flame colour to be established. After making adjustments re- place the gasket and cover plate. Re-secure the control panel plate.
