restriction plate setting. Qualified service personnel
must perform supply line/manifold gas line pressure
adjustments and restrictor plate adjustments. Do not
attempt to complete any part of the installation or
adjustment of this unit unless technically qualified.
Air Shutter Adjustments
WARNING: THE ADJUSTING BOLT IS HOT!
WARNING: THE AIR SHUTTER IS FACTORY SET
AND ONLY A QUALIFIED GAS TECHNICIAN
SHOULD MAKE ADJUSTMENTS.
The air shutter is adjustable while the stove is
burning. Loosen the lock nut on the adjusting bolt
located in the lower rear center of the stove. Move
the bolt in or out to adjust the flame pattern
(see
figures 32 and 33).
Turn the bolt in to open the air
shutter, and turn it out to close the shutter. When
the flame pattern is correct, hold the adjusting bolt
head still with a wrench and tighten the locking nut
to the body of the stove.

Note:
Very little movement is needed to substantially
change the burn and flame patterns. Some
conditions cannot be corrected through air shutter
adjustment; an adjustment must be made to the gas
supply pressure. Supply line/manifold gas line
pressure adjustments must be performed by
qualified service personnel. Do not attempt to
complete any part of the installation or adjustment of
this unit unless technically qualified to do so.
Burner Flame Appearance
Once the unit is lit, observe the flame pattern and
adjust as necessary. Also, a periodic visual check of
the burner flame should be performed. The burner
flames can be adjusted by means of the air shutter.
To determine if the burner flame needs adjustment,
it is necessary to view the flame pattern with the
valve output at its highest setting. Allow the unit to
operate for 10 minutes enabling the entire unit to
reach temperature and for the flame pattern to
stabilize. The flame pattern should be similar to the
one shown in
figure 34
. There are several guidelines
to aid in determining if the flame pattern is correct:
1. The flame should not be dirty, smoky, sooty, or
lick the top of the stove.
2. The flame should not rise off the pan burner; this
is called “lifting”.
3. Flames should not impinge heavily on the log
set. They should “fit” through the pre-formed
spaces designed in the log set.
