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!
