VENTURI ADJUSTMENT

Natural gas models have air shutters set at 3/16 (.188")
inch open. Propane gas models have air shutters set at 3/
8 (.375) inch open. 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 ap-
pear 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 GAS INSTALLER!
