Adjust the pilot screw to provide properly sized flame. Turn
in a clockwise direction to reduce the gas flow.
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; al-
low 15 to 30 minutes for the final flame colour to be estab-
lished.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A
QUALIFIED GAS INSTALLER!
