Flame Appearance / Air Shutter
Adjustment
THIS FIREPLACE IS SHIPPED FROM THE FACTORY
EQUIPPED TO USE NATURAL GAS. IF THE BURNER HAS
BEEN CONVERTED FOR USE WITH PROPANE, IT MAY
BE NECESSARY TO ADJUST THE AIR SHUTTER TO
ACHIEVE AN IDEAL AIR-TO-GAS RATIO. See page 22.
WARNING:
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED, PROFESSIONAL SERVICE
TECHNICIAN.
The air shutter adjustment can also help achieve the
desired flame appearance. Generally, flame appear-
ance is a matter of individual preference, however a
warm yellowish flame is most common.
Closing Closing Closing Closing Closing the air shutter the air shutter the air shutter the air shutter the air shutter - in extreme cases may
generate very long yellow flames resulting in soot.
Sooting produces black deposits on the logs, on
the inside walls of the appliance, and potentially
on the exterior termination cap.
Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air
shutter opening.

is blue and transparent, or “anemic”. This flame is
generally more efficient, but not as attractive.

not lifting or floating. The flame should be blue in
color around the pilot hood,,,,, with traces of yellow
toward the outer edges. It is imperative that the
pilot flame engulf the top 3/8” of the thermopile
(power generator) and the top 1/8” of the quick
drop-out thermocouple. The pilot flame should
project out of the pilot hood 1” at all three ports,
extending to reach the burner plate ports. See fig. 28.

The Pilot Shutter, located directly behind the pilot
assembly, is set fully-open at the factory. Those
installations which include a long, external vent
run may be susceptible to draft conditions that
can affect pilot stability and cause the valve to
shut off automatically. In such cases, adjusting the
shutter to a closed, or partially-closed postion, will
help improve pilot stability.

T::::: Your gas fireplace is
equipped with a variable gas control valve. This
valve provides easy adjustment of the flame
height appearance and heat output. To adjust the
flame between the HI and LO setting, rotate the
HI/LO knob, located in the center of the valve face.
Flame height will adjust approximately 50%
between the HI and LO settings.
NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK
LOG PLACEMENT IF ANY SOOT OR SMOKE IS APPAR-
ENT. IF SOOT OR SMOKE PERSISTS, THE AIR SHUTTER
MAY NEED TO BE ADJUSTED.
CAUTION:
DO NOT ATTEMPT TO ALTER THE FLAME APPEARANCE
BY PLACING THE GAS CONTROL IN ANY POSITION
OTHER THAN THE FULL “ON” POSITION.
