Front Glass Enclosure Panel, Removal
and Installation.
To install the front glass enclosure panel,
proceed as follows:
1. Retrieve the glass door frame. Visually
inspect the gasket on the backside of the
panel. The gasket surface must be clean, free
of irregularities and seated firmly.
2. Position the door frame in front of the
firebox opening and engage the top flange
over the lip at the top of the firebox opening.
3. Swing the door down and back. Ensure the
gasket seats evenly as the door draws shut.
Engage the Vee-flange at the bottom of the
door with the latches and close the latches to
secure the door.
4. Reinstall the top louver assembly or radiant
panel.
Burner Adjustments
The following paragraphs address burner ad-
justment concerns and procedures.
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
termed anemic. If the air shutter opening is too
small sooting may develop.
These are direct-vent appliances. They are
designed to operate only with the front glass
enclosure panel properly installed. Generally,
the glass enclosure panel should not be re-
moved except to gain access to the compo-
nents within the firebox, and the appliance
may only be operated without the front glass
enclosure panel in place for very brief periods
of time during initial appliance checkout and
adjustment.
See
Figure 5
and remove the front glass
enclosure panel as follows:
1. Remove the top louver assembly or radiant
panel.
2. Open the hinged drop-down control com-
partment access panel.
3. Locate the two (2) latches at the top of the
control compartment and disengage them from
the floor frame bottom Vee-flange, pulling
down on their handles to open them.

During this appliance checkout and adjust-
ment period, a potential safety hazard exists
- EXERCISE EXTREME CAUTION to prevent
the occurrence of any burn injuries from the
exposed flames or hot surfaces.
Also note, that while the front glass enclosure
panel is removed, the flame appearance will
appear to be smaller than normal.
CAUTION: DO NOT ATTEMPT TO TOUCH THE
FRONT ENCLOSURE GLASS WITH YOUR
HANDS WHILE THE FIREPLACE IS IN USE.
Note: Clean glass after first two weeks of
operation.
Glass Cleaning
It will be necessary to clean the glass periodi-
cally. During start-up it is normal for conden-
sation to form on the inside of the glass. This
can cause lint, dust and other airborne par-
ticles to cling to the glass surface. Also initial
paint curing may deposit a slight film on the
glass. It is therefore recommended that the
glass be cleaned two or three times with a non-
ammonia household cleaner and warm water
(a gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, de-
pending on the circumstances present.
WARNING: DO NOT USE ABRASIVE
CLEANERS. NEVER CLEAN THE GLASS
WHEN IT IS HOT.
WARNING: NEVER OPERATE THE AP-
PLIANCE WITHOUT THE GLASS EN-
CLOSURE PANEL IN PLACE AND SE-
CURE. DO NOT OPERATE APPLIANCE

The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. However, more frequent periodic inspec-
tions and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by whom
they should be performed. Always verify proper
operation of the appliance after servicing.
