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 28. 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.

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 29 &
30). The adjustment point is on the left side of the
firebox (from front).

OSITION
The restrictor plate is factory set in the fully open
position for shipping. Leave in the open position until
installation is complete and adjust as necessary
from there. 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 the baffle plate.
Depending on your vent configuration, you may
need to adjust the restrictor plate position to reduce
draft.
