10.3 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 carboning. 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!
10.4 FLAME CHARACTERISTICS
It's important to periodically perform a visual check of the pilot and
burner fl ames. Compare them to the illustrations provided. If any fl ames
appear abnormal call a service person.
