4.17 AIR SHUTTER CONTROL AND FLAME APPEARANCE
During initial installation, the air shutter opening
should be checked to be certain that the shutter is set
correctly at 1/8" open for natural gas and 1/2"
minimum open for L.P. gas. NOTE: For altitudes above
5,000’, some variations may be required.
Be sure burner and logs are properly installed. After
log set has been properly installed, adjustments to
the air shutter shall be made for final flame
appearance. These small shutter adjustments can be
made by the following procedure:
NOTE: All adjustments to the air shutter
setting must be made by a qualified installer,
service agency, or the gas supplier. Very
small changes in shutter settings make major
changes in flame appearance.
Two Air Shutter Control Knobs are located behind the
right-side access door. The shutter control knob
located on the top controls the front burner flames. The shutter control knob located on the bottom controls the rear-most
burner flames. After fireplace has warmed up, if flame is too blue, close air shutter in small 1/8" increments until flame turns
desired realistic yellow. Use glass latch tool to hook end and slide control.
1. If flame is causing soot on viewing glass, open air shutter fully until sooting stops. Continue burning unit with air
shutter fully open for four to six hours until all internal deposited soot has burned off.
2. Once deposited soot has disappeared, close air shutter in increments of 1/8”.
LPG Air shutter settings hint: A properly adjusted air shutter setting will yield burner flames that have an
approximate 2” high blue color base. If yellow colored flames are starting at burner level, air shutter is
closed too far and will create soot. If you observe that the flame is yellow starting very close to or at the
burner surface level, open air shutter. Also, if a log or part of a log is suspended and hanging inside a yellow
portion of the flame, soot can form easily on the part of the log that is inside the yellow flame area.
IMPORTANT: Try each new shutter setting approx. ½ hr. before mak ing additional changes. NOTE: Changes
in front burner flame can be made by re-arranging the coals and front burner air shutter opening.
