Step 9. REMOVING AND INSTALLING THE
GLASS DOOR
WARNING
• Do not attempt to substitute the
materials used on these doors,
or replace cracked or broken
glass.
• Handle this glass with extreme
care! Glass is susceptible to
damage - Do not scratch or
handle roughly while reinstalling
the glass door frame.
• The glass door(s) of this appli-
ance must only be replaced as a
complete unit as provided by the
manufacturer. Do not attempt
to replace broken, cracked or
chipped glass separately.
• Do not attempt to touch the front
enclosure glass with your hands
while the fireplace is in use.
• DO NOT abuse glass door by
striking or slamming shut.
WARNING
The door should easily close
without needing to be pressed
down. If it has to be pressed
down to close, the gasket in the
top of the door should be dressed
so it lays on the glass.
WARNING
Do not operate appliance with
the glass front removed, cracked
or broken.
AVERTISSEMENT
Ne pas utiliser l'appareil si le
panneau frontal en verre n'est
pas en place, est craqué ou
brisé.
Only doors certified with the appliance
shall be used.
Seules des portes certifiées pour cet
appareil doivent être utilisées.
These are B-vent appliances. They are designed
to operate only when the glass enclosure panels
are installed. Generally the glass enclosure panels
should not be removed except to gain access to
the components within the firebox.
Removing Glass Enclosure Panel
(see Figure 24)
To access the glass door securing latches, first
remove the hood by pulling firmly straight away
from the unit. Remove the front face assembly by
lifting up top and bottom evenly approximately
1/2" and pulling straight out from the unit once
the brackets are disengaged.
Locate the latch at the top of the control com-
partment and disengage them from the door
frame bottom vee-flange, pulling down on its
handle to open it.
Installing Glass Enclosure Panel
(see Figure 24)
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 24). 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 latch located underneath the
firebox floor to the door's vee-flange. Close the
latch securely.
NOTE: Front Face Assembly with
barrier installed must be rein-
stalled prior to operation.

Step 10. BURNER ADJUSTMENTS

Flame Appearance and sooting
Proper flame appearance is a flame which 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 enter-
ing 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
Front Glass
blue and transparent. These weak, blue and
Enclosure Panel
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.
