Step 11. BURNER ADJUSTMENTS
Flame Appearance and Sooting
Proper flame appearance is a flame that is
blue at the base and becomes yellowish-
orange in the body of the flame.
When the appliance is first lit, the entire
flame may be blue and will gradually turn
yellowish-orange during the first 15 minutes
of operation. If the flame remains blue, or if
the flame is orange with evidence of sooting
(black tip), the air shutter opening may need
to be adjusted.
If the air shutter opening is closed too far,
sooting may develop. Sooting is indicated
by black puffs developing at the tips of very
long orange flames. Sooting results in black
deposits forming on the logs, appliance
inside surfaces and on exterior surfaces
adjacent to the vent termination.
Sooting is caused by incomplete combustion
in the flames and lack of combustion air
entering the air shutter opening. To achieve
a warm yellowish-orange flame with an
orange body that does not soot, the shutter
opening must be adjusted between these two
extremes.
Air Shutter Adjustment Guidelines
• If there is smoke or soot present, first
check the log set positioning to ensure
that the flames are not impinging on
any of the logs. If the log set is properly
positioned and a sooting condition still
exists, then the air shutter opening should
be increased.
• The more offsets in the vent system, the
larger the air shutter opening will need
to be.
• An appliance operated with the air shutter
opened too far, may have flames that
appear blue and transparent. These weak,
blue and transparent flames are termed
anemic.
• Propane models may exhibit flames
which candle or appear stringy. If this is
present and persists, adjust the air shutter
to a more closed position, then operate
the appliance for a few more minutes to
ensure that the flame normalizes and the
flames do not appear sooty.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.
Figure 54: Door Removal
Removing the Glass Enclosure Panel
(see
Figure 54
)
Remove the top radiant panel. To access the
glass door securing latches, first open the
lower control compartment door (
Figure 54
)
by pushing in simultaneously the left and
right top corners of the door (the door is
hinged at the bottom).
Remove the bottom compartment door by
sliding the hinge pin, located at the door’s left
side, to the right until it disengages from the
left corner post hole. Pull the door diagonally
to the left, away from the fireplace.
Locate the two (2) latches at the top of the
control compartment and disengage them
from the door frame bottom vee-flange,
pulling down on their handles to open them.
Installing the Glass Enclosure Panel
(see
Figure 54
)
Retrieve the glass door. Visually inspect the
gasket on the backside of the frame. Gasket
surface must be clean, free of irregularities
and seated firmly.
Position the door in front of the firebox
opening with the bottom of the door held
away from the fireplace
(Figure 54)
. Hook the
top flange of the door frame over the top of
the firebox frame.
Let the bottom of the door frame swing
gently in towards the fireplace ensuring that
the gasket seats evenly as the door frame
draws shut. Fasten the two latches located
underneath the firebox floor to the door's
vee-flange. Close both the latches securely.
