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

9.5 RESTRICTING VERTICAL VENTS
77.3
Vertical installations may display a very active fl ame. If this appearance is not desirable, the vent exit must
be restricted using a restrictor vent kit. Refer to “ACCESORIES” in the “REPLACEMENTS” section for the
appropriate kit. This will reduce the velocity of the exhaust gases, slowing down the fl ame pattern and creating
a more traditional gentle fl ame appearance. Specifi c instructions are included with the kit.
