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 21
. 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.

Restrictor Plate
The restrictor plate is used to control excess draft if
necessary. Controlling the draft also changes the
aesthetics of the flame. The restrictor plate has a
large range of unlimited settings
(see figures 22 &
23).
The adjustment point is on the left side of the
firebox (from front).
Restrictor Plate Position
The restrictor plate may be factory set in the fully
closed position for shipping. If so, set to the fully
opened position. This ensures proper flames for a
wide variety of vent configurations and efficiency.
The restrictor plate consists of a rotating flap in front
of the firebox exhaust port behind baffle plate.
Depending on your vent configuration, you may
need to adjust the restrictor plate position to reduce
draft.
