Flame Appearance -

Air Shutter Adjustment

WARNING: AIR SHUTTER ADJUSTMENTS SHOULD ONLY
BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
The air shutter setting at the burner orifice can be adjust-
ed to achieve the desired flame appearance. The shutter is
set in the mid-range at the factory, however, you will want
to adjust it if a fuel conversion kit has been installed or if
the flame pattern is not as desired. The adjustment stem is
located under the firebox, directly behind the gas control
valve. Generally, flame appearance is a matter of prefer-
ence, however most people enjoy a warm yellowish flame.
Too much air - the appliance will generate a flame that
is blue and transparent, or an "anemic" flame.
Not enough air - the burner will 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. Open the shutter setting to allow more air.
To adjust the air shutter:
1. Locate and loosen the adjustment stem wing nut pro-
truding from the bottom of the firebox, directly behind
the gas valve. See fig. 26.
2. Push the stem back to decrease air, or pull it forward to
increase air. Make adjustments in small increments
(1/8") and allow the burner to " settle in" for a few
minutes before making another one. Small shutter
adjustments can produce dramatic changes to flame
characteristics.
4. Re-tighten the wing nut when the desired flame ap-
pearance has been achieved.
