Air Shutter Adjustment Guidelines
• If there is smoke or soot present, first check
the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.
• The more offsets in the vent system, the larger
the air shutter opening will need to be.
• An appliance operated with the air shutter
opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.
• Propane models may exhibit flames which
candle or appear stringy. If this is present and
persists, adjust the air shutter to a more closed
position, then operate the appliance for a few
more minutes to ensure that the flame nor-
malizes and the flames do not appear sooty.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

Burner Air Shutter Adjustment Procedure
WARNING
• Air shutter adjustment should
only be performed by a quali-
fied professional service
technician.
• Ensure that the front glass
door assembly is in place and
sealed After adjustment.
CAUTION
Soot will be produced if the air
shutter is closed too much. Any
damage due to carboning result-
ing from improperly setting the
air shutter is not covered under
the warranty.
To adjust the flame, rotate the air shutter toward
the back or toward the front of the fireplace.
Position the air shutter to the factory setting as
shown in the table in Figure 48. Allow the burner
to operate for at least 15 minutes. Observe the
flame continuously. If it appears weak or sooty
as previously described, adjust the air shutter
until the flame appearance is as desired.
Use the remote to adjust the flame height
as desired.
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs.
Operate the appliance for a period of time as the
effect diminishes, ensuring that the appliance
does not develop sooty flames. When satisfied
that the appliance operates properly, proceed
to finish the installation.
