Removing Glass Enclosure Panels
(see Figure 6 )
1. Remove the top louver assembly or radiant
panel by pulling it out and off.
2. Open the control compartment access panel
by actuating the spring-loaded magnetic
catches securing the panel (gently depress the
outer top corners of the louvered or radiant
panel until the catches "pop" the door free,
allowing it to swing out and down to the open
position).
3. Locate the two (2) latches at the top of the
control compartment. To disengage the two
latches from the bottom vee-fl ange of the
glass enclosure panel, reach for the handles
located towards the back of the latches and
pull the handles down toward the front of
the appliance.
4. Swing the bottom of the door out and raise
it slightly to lift the top fl ange of the door
frame away from the appliance.
Installing Glass Enclosure Panels
(see Figure 6 )
1. Visually inspect the gasket on the backside of
the panels. The gasket surface must be clean,
free of irregularities and seated fi rmly.
2. Position the glass enclosure panel in front of
the fi rebox opening at a 45 degree angle and
engage the top fl ange over the lip at the top
of the fi rebox opening. See Figure 6.
3. Swing the glass enclosure panel down and
back. Ensure the gasket seats evenly as the
panel draws shut. Engage the Vee-fl ange at
the bottom of the panel with the latches and
close the latches to secure the panel.
4. Close the bottom control compartment
access panel.
WARNING
Do not attempt to touch the front
enclosure glass with your hands
while the fi replace is in use.
WARNING
Do not operate appliance with the
glass front removed, cracked or
broken. Replacement of the glass
should be done by a licensed or
qualifi ed service technician.
WARNING
Handle this glass with extreme
care! Tempered glass is suscep-
tible to damage – do not scratch
or handle roughly while rein-
stalling the glass door frame.
WARNING
Do not attempt to substitute the
materials used on this door, or
replace cracked or broken glass
with any materials other than
those provided by the appliance
manufacturer.
WARNING
The glass door 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.
These fi replaces are designed to operate only
with the glass enclosure panels properly
installed. Generally the glass enclosure panels
should not be removed except to gain access
to the components within the fi rebox, 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.
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 (or any of
the panels) is removed, the fl ame appearance
will appear to be smaller than normal.
Cleaning Logs And Burner
Carefully remove the logs (use care when han-
dling the fi ber logs, as they become quite fragile
after curing). Vacuum out any foreign matter
(lint, carbon, etc.) on the burner. Ensure the
burner ports are “open.” Remove any carbon
deposits from the under side of the logs using
a vacuum cleaner, or a soft bristled brush (i.e.
paint brush). Note: Improper positioning of
logs can create carbon build-up and will alter
the performance of the appliance.
Replacing Logs -
If the logs become damaged by accident or
improper handling and need replacement, use
only the proper replacement logs from manufac-
turer (see Page 23 for ordering information).
Re-Install Embers, Logs and Vermiculite
- Carefully follow placement instructions on
Pages 9 to 12 ). All logs should fi t onto cor-
responding pins and/or log stoppers. This will
ensure a proper fl ame and safe combustion.
Inspect Wiring
Refer to wiring diagrams on Page 14.
Inspect and clean all wire connections. Ensure
that there is no melting or damage. Inspection
should include:
• Terminals at the Valve
• OFF/ON
Switch
• (Optional Control Switch) Remote Control
or Remote Wall Switch Kit
Inspect Burner Flame Appearance
Ensure that the burner flame appearance
resembles the fl ame shown in Figure 15 and
as described in Flame Appearance and Sooting
on Page 13. The Homeowner must contact
a qualifi ed service technician at once if any
abnormal condition is observed.
Small Area Paint Touch-up
The fi nish of the appliance is a high qual-
ity powdercoat. Only use factory supplied
powdercoat paint kit for touch-ups. Paint is
available at your local authorized Lennox Hearth
Products dealer (cat. no. 90L74). Never attempt
to paint a hot fi replace.
Do not attempt to repaint the appliance until the
fi nish is completely cured (see Burn-In Period
on Page 3 ). If the surface later becomes stained
or marred, it may be lightly sanded and touched
up with spray paint.
WARNING
Label all wires prior to discon-
nection when servicing con-
trols. Wiring errors can cause
improper and dangerous opera-
tion. Verify proper operation
after servicing.
