Flame Appearance / Air Shutter
Adjustment
Locate the Primary Air Shutter control under the
firebox floor above the gas valve. See fig. 37. The
shutter is set at the midpoint of its adjustment
range at the factory. This will give good results in
the majority of installation configurations, however,
you may need find it necessary to adjust it to get the
best flame picture depending upon the your specific
installation.
With the burner operating, loosen the wingnut
on the shutter stem. Push the stem back toward the
rear of the stove will decrease combustion air. Pull it
forward to increase air.
Generally, flame appearance is a matter of
individual preference, however a warm yellowish
flame is most common.
Closing the air shutter - in extreme cases may
generate very long yellow flames resulting in soot.
Sooting produces black deposits on the logs, on the
inside walls of the appliance, and potentially on
the exterior termination cap.
Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air
shutter opening.
Opening the air shutter - will generate a flame that
is blue and transparent, or “anemic”. This flame is
generally more efficient, but not as attractive.
Allow the burner to operate at the highest setting
for 20-30 minutes before making any adjustments.
Always make adjustments in 1/8” increments and
allow the burner to settle in for 10- 15 minutes
between additional adjustments.

Operation Notes
1. For the first several hours of operation, it is
common to detect some odor as the metal and
manufacturing materials cure under heat. This
condition is temporary and can be alleviated by
allowing plenty of fresh air to circulate through the
area.
2. Condensation may develop on the glass upon each
lighting of the appliance. This “fog” will disappear
as the glass heats.
3. Keep the controls and the area under the appliance
free of dust. Always keep the appliance area clear
and free from combustible materials, gasoline and
other flammable liquids.
4. This appliance can be operated with a continuously
burning pilot flame. Exercise caution when using
household products containing combustible
vapors.
