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!
