Flame Appearance and Sooting

Proper flame appearance is a flame which is
blue at the base and becomes yellow-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
gradually turn yellow-orange during the first
15 minutes of operation. After 15 minutes of
operation, if the flame is blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.
If the air shutter opening is closed too far,
sooting may develop. Sooting is indicated by
black puffs developing at the tips of very long
orange flames. Sooting results in black deposits
forming on the logs, appliance inside surfaces
and on exterior surfaces adjacent to the vent
termination. Sooting is caused by incomplete
combustion in the flames and lack of combustion
air entering the air shutter opening. To achieve
a warm yellow-orange flame with an orange
body that does not soot, the shutter opening
must be adjusted between these two extremes.

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.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.
