Ceramic Burner Fissures
The ceramic burner may develop surface fissures at
or after the initial burn. These fissures are normal,
and have no effect on the operation, or safety of the
stove.

batteries as necessary.
However, if a crack is found that penetrates into the
fuel accumulation area below the ceramic surface;
discontinue operation until the stove is checked by a
qualified technician.
Air Shutters
The air shutters are used to regulate the air-to-gas
combustion mixture of each burner, which in turn
influences the size and color of the flames. The air
shutters are factory positioned in the general
location needed for testing the unit with natural gas
(NG) and minimum venting. However, if the unit is
not burning as well as it should in your installation,
then the air shutters may need adjusting.
To determine if an 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
burner or at the base of the logs is
completely blue, the air shutter may be open
too far;
2. If the flame is dirty, sooty, or licks the top of
the firebox, the air shutter may be closed too
far.
Refer to Figure 12 on page 15 for minimum requires
settings. 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
adjustments. Do not attempt to complete any part of
the installation or adjustment of this unit unless
technically qualified.
