BURNER ADJUSTMENT

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 insert is first lit, the
entire flame may be blue and will gradually turn yellow/orange during
the first 6-8 minutes of operation. If after 6-8 minutes the flame stays
blue, or if the flame is orange with evidence of sooting (black tip), the
air shutter may require adjustment.
An appliance operated with an air shutter opening that is too large will
exhibit flames that are blue and transparent. These weak, blue and
transparent flames are termed anemic. If the air shutter opening is too
small, sooting may develop.
Figure 15
Figure 19
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-to-orange flame that does not soot, the
shutter opening must be adjusted between these two extremes.
No smoke or soot should be present. Reposition the logs if flames
impinge on any of them. If the logs are properly positioned and
sooting conditions exist, the air shutter opening on the main burner
tube should be adjusted.
Ensure that the front glass panel is in place and
sealed during adjustment.
