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 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 color to be established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED
INSTALLER!

RESTRICTOR PLATE INSTALLATION

Vertical terminations may display a very active flame. If
this appearance is not desirable, the vent exit must be
restricted using restrictor plate, W500-0205 (supplied with
unit). This reduces the velocity of the exhaust gases,
slowing down the flame pattern and creating a more
traditional appearance.
Install the plate over the exhaust outlet.
