Air Shutter

The air shutter is used to regulate the air-to-gas
combustion mixture, which in turn influences the size
and color of the flames. The air shutter is factory
positioned in the general location needed for testing
the unit with LP gas and minimum venting (fully
open). If using natural gas (NG) or if the unit is not
burning as well as it should in your installation, then
the air shutter may need adjusting.
To determine if the air shutter needs adjustment, it is
necessary to view the flame pattern with the burner
output set at its highest setting. Allow the unit to
operate for at least 10 minutes to allow the entire
unit to reach temperature, and for the flame pattern
to stabilize. Generally, the more air (open shutter) in
the mixture, the bluer the flame. Less air (closed
shutter) results in a more yellow flame, but too little
air will result in incomplete combustion, low
efficiency and a dirty burn. There are two simple
guidelines to aid in determining the correct flame
pattern:
1. If the flame just above the surface of the
2. If the flame is dirty, sooty or licks the top of
Some conditions cannot be corrected through air
shutter adjustment; an adjustment must be made to
the gas supply pressure or by changing the
restriction plate setting. Qualified service personnel
must perform supply line/manifold gas line pressure
adjustments and restrictor plate adjustments. Do not

SHOULD MAKE ADJUSTMENTS.
The air shutter is adjustable while the stove is
burning. Loosen the set screw on the adjusting rod
located in the lower rear center of the stove. Move
the rod in or out to adjust the flame pattern (see
Figures 39 and 40). Push the rod in to open the air
shutter, and pull it out to close the shutter. When
the flame pattern is correct, tighten the set screw
without letting the rod move.
