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 fi rmly.
2. With the stove top off, position the glass
front enclosure panel into the front open-
ing with the gasket facing the relief door
(see Figure 6). Let the bottom of the door
frame gently slide down, then hook the top
fl ange of the glass frame over the top of the
fi rebox frame.
3. Fasten the two latches located beneath the
fi rebox bottom to the glass frame vee-fl ange.
Close both the latches securely.
4. Reinstall the cast iron stove top (read "Cau-
tion," at the bottom of left column).
5. Reinstall Trivet.
Sooting is caused by incomplete combustion in
the fl ames and a lack of combustion air enter-
ing the air shutter opening. To achieve a warm
yellow to orange fl ame with an orange body
that does not soot, the shutter opening must
be adjusted between these two extremes. No
smoke or soot should be present. Reposition the
logs to ensure they are in the proper pin locations
if the fl ames impinge on any of them.
If the logs are properly positioned and soot-
ing conditions exist, the air shutter opening
on the main burner tube should be adjusted.
Normally, the more offsets in the vent system,
the greater the need for the air shutter to be
opened further.
WARNING: NEVER OPERATE THE APPLIANCE
WITHOUT THE GLASS ENCLOSURE PANEL
IN PLACE AND SECURE. DO NOT OPERATE
APPLIANCE WITH THE FRONT GLASS PANEL
CRACKED, BROKEN OR MISSING. REPLACE-
MENT PANELS ARE AVAILABLE THROUGH YOUR
LOCAL LENNOX HEARTH PRODUCTS DEALER
AND MUST BE INSTALLED BY A LICENSED OR
QUALIFIED SERVICE TECHNICIAN.
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 removed
except to gain access to the components within
the fi rebox, and the appliance may only be oper-
ated without the front glass enclosure panel in
place for very brief periods of time during initial
appliance checkout and adjustment.
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 fl ames or hot surfaces. Also note,
that while the front glass enclosure panel is
removed, the fl ame will appear to be smaller
than normal.
WARNING: DO NOT ATTEMPT TO SUBSTITUTE
THE MATERIALS USED ON THIS DOOR, OR
REPLACE CRACKED OR BROKEN GLASS WITH
ANY MATERIALS OTHER THAN THOSE PRO-
VIDED BY THE APPLIANCE MANUFACTURER.
THE GLASS DOOR OF THIS APPLIANCE MUST
ONLY BE REPLACED AS A COMPLETE UNIT AS
PROVIDED BY THE MANUFACTURER. DO NOT
ATTEMPT TO REPLACE BROKEN, CRACKED
OR CHIPPED GLASS SEPARATELY.
WARNING: AIR SHUTTER ADJUSTMENT
SHOULD ONLY BE PERFORMED BY A
QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
WARNING: HANDLE THE GLASS WITH
EXTREME CARE! CERAMIC GLASS IS
SUSCEPTIBLE TO DAMAGE (SCRATCHES,
FOR EXAMPLE) – HANDLE GLASS DOOR
(GLASS ENCLOSURE PANEL) GENTLY WHILE
REINSTALLING IT.
Burner Adjustments
The following paragraphs address burner
adjustment concerns and procedures.
Flame Appearance and Sooting:
Generally most people prefer the warm glow of
a yellow to orange fl ame. Appliances operated
with air shutter openings that are too large will
exhibit fl ames that are blue and transparent.
These weak, blue and transparent fl ames are
termed anemic. If the air shutter opening is too
small sooting may develop.
Open both Latches as shown.
Figure 4
3. Reach under the bottom front of the front
glass enclosure and pull it forward as shown
in fi gure 5.
Figure 5
4. Lift glass assembly up and out and carefully
set aside in a safe place (see fi gure 6).
Figure 6
1. Remove the trivet, then the cast iron stove top
by carefully lifting them up and off and setting
them aside (READ CAUTION BELOW).
Sooting is indicated by black puffs developing
at the tips of very long orange fl ames. Sooting
may result in black deposits forming on the
logs, appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.

2. Locate and open the 2 latches as shown in
Figure 4 (locate below the stove body).
CAUTION: THE CAST IRON STOVE TOP IS VERY
HEAVY AND MAY REQUIRE A MINIMUM OF
TWO PEOPLE TO LIFT; ONE PERSON ON EACH

~20 POUNDS AND THE CI2500 SERIES CAST
TOP WEIGHS ~40 POUNDS).
