Adjust the Air Shutter to Ensure Proper Flame Appearance

16.
• Air shutter adjustment should only be performed by a qualified professional service technician.
• Ensure glass door is in place and sealed during adjustment.
• Soot will be produced if the air shutter is closed too much. Any damage due to sooting,
resulting from improperly setting the air shutter, is not covered under the warranty.
• The air shutter door and nearby appliance surfaces are hot. Exercise caution to avoid
injury while adjusting flame appearance.
Flame Appearance and Sooting
The flame should be blue at the base, and yellow-orange in the body of the flame.
When the fireplace is first lit, the entire flame may be blue and will gradually turn yellow-orange during the first 30
minutes of operation. If the flame remains 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 fireplace 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.
