VENTURI ADJUSTMENT

This appliance has an air shutter that has been factory set open according
to the chart below:
Regardless of venturi orientation, closing the air shutter will cause a more
yellow flame, but can lead to carbonization. Opening the air shutter will
cause a more blue flame, but can cause flame lifting from the burner ports.
The flame may not appear yellow immediately; allow 15 to 30 minutes for
the final flame colour to be established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED
INSTALLER!
These settings are for rear vented (maximum) horizontal termination. Adjustment may be required depending
on fuel type, vent confi guration and altitude.
To access the air shutter, remove the two screws that secure the cover to the air housing, taking care not to
damage the gasket.
