Flame Picture / Air Shutter Adjustment
WARNING:
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
The volume of air supplied to the burner is
regulated by the primary air shutter, located under the
firebox at the center of the valve compartment. See
fig. 8.3 The factory air shutter setting is 1/2 open and
will not require adjustment for most installations. Air
volume can be adjusted if necessary to improve the
flame picture or to correct poor combustion.
The burner is very sensitive to air supply volume.
Make air adjustments in 1/8" - 1/4" increments. Wait
a few minutes to observe the flame pattern changes
before making subsequent adjustments. Repeat the
process until a satisfactory flame picture is achieved.
Insufficient combustion air will promote inefficient
combustion resulting in very long yellow flames and
soot. Sooting produces black deposits on the logs, on the
firebox walls, and potentially on the flue termination
cap.
Very blue, transparent, or weak "anemic" flames are
indications of too much air which, although efficient,
are not very attractive.
Generally, propane fuel will require a less restricted
air shutter setting than will natural gas.
• Loosen the shutter handle wing nut.
• PUSH the shutter handle IN to DECREASE air volume.
• PULL the handle OUT to INCREASE air volume.
• Tighten the lock nut after shutter adjustment.
NO SMOKE OR SOOT SHOULD BE EVIDENT.
Confirm correct log placement if any soot or smoke
appears. If the conditions persists, adjust the air
shutter to increase air volume and promote efficient
combustion.
