See fig. 37. The shutteris set at the midpoint of its adjustment range at thefactory. This will give good results in the majority ofinstallation configurations, however, you may needfind it necessary to adjust it to get the best flamepicture depending upon the your specific installation.With the burner operating, loosen the wingnuton the shutter stem. Push the stem back toward therear of the stove will decrease combustion air. Pull itforward to increase air.Generally, flame appearance is a matter of individualpreference, however a warm yellowish flame ismost common.• Closing the air shutter - in extreme cases maygenerate very long yellow flames resulting in soot.Sooting produces black deposits on the logs, on theinside walls of the appliance, and potentially onthe exterior termination cap.Sooting is caused by incomplete combustion in theflames and lack of combustion air entering the airshutter opening.• Opening the air shutter - will generate a flame thatis blue and transparent, or “anemic”. This flame isgenerally more efficient, but not as attractive.• Allow the burner to operate at the highest settingfor 20-30 minutes before making any adjustments.Always make adjustments in 1/8” increments andallow the burner to settle-in for 10- 15 minutesbetween additional adjustments.Primary AirShutterFigure 37.
