flame characteristics

It's important to periodically perform a visual check of
the pilot and burner flames. Compare them to the
illustration provided. If any flames appear abnormal,
call a service person.
3.2

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 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!
note:
It is important that the orifice is securely inserted into the venturi.
