3. Keep the lower control compartment clean
by vacuuming or brushing at least twice a
year. More frequent cleaning may be required
due to excessive lint from carpeting, bedding
materials, pet hair, etc. It is very important
that the control compartments, burners
and circulating air passageways of the
appliance are kept clean.
4. Always turn off gas to the pilot (millivolt
appliances) and let the appliance cool down
before cleaning. Before re-lighting, refer
to the lighting instructions in this manual.
Lighting instructions may also be found
on the pull out lighting instruction labels
attached to the gas control valve.
5. Always keep the appliance area clear and
free from combustible materials, gasoline
and other fl ammable liquids.
6. Remember, Millivolt appliances have a continu-
ous burning pilot fl ame. Exercise caution when
using products with combustible vapors.

MAINTENANCE

(See Maintenance Schedule, Page 22)
Refer to the maintenance schedule for maintenance
tasks, procedures, periodicity and by whom they
should be performed. Always verify proper opera-
tion of the appliance after servicing.
WARNING
Turn off gas and electrical power
before servicing the appliance.
CAUTION
Wear gloves and safety Glasses
for protection while doing
required maintenance
IMPORTANT
Always verify proper operation
after servicing.
Before re-lighting the fi replace, refer to the
lighting instructions in this manual. Instruc-
tions are also found on pull-out panels
located below the glass door in the control
compartment.
Inspect Venting System
The appliance and venting system should be
thoroughly inspected before initial use and
at least annually by a qualifi ed service techni-
cian (inspection should include ensuring that
exhaust or intake passages are unobstructed
and vent components are properly assembled
and not damaged).
6
If the venting system is disassembled for any
reason, a qualifi ed service technician should
follow vent installation instructions for proper
reassembly and proper sealing of the venting
system components. However, more frequent
periodic inspections and cleanings should be
performed by the homeowner.
Clean Lower Control Compartment
Keep lower control compartment clean by
vacuuming or brushing it out at least twice a
year (also clean the air venturi with a brush or
wire). More frequent cleaning may be required
due to accumulation of lint from carpeting,
bedding materials, pet hair, spider webs, etc. It
is very important that control compartments,
burners, circulating air passageways and air
venturi on the appliance are NOT obstructed
in any way.
Cleaning Glass
(see Front Glass Enclosure Panel, Removal and
Installation on Page 7)
Note: Clean glass after fi rst two weeks of opera-
tion (after Burn-In period is over) and then only
when necessary and when the fi replace is cool.
Wipe surface with clean, dampened, soft cloth.
Follow with dry, soft towel as desired. Take care
not to scratch the glass surface.
The viewing glass should be cleaned periodi-
cally to remove any build-up caused from the
following:
Do not use abrasive cleaners
on glass. Never clean the glass
when it is hot.
• During start-up, it is normal for condensa-
tion to form on the inside of the glass (this
.
condensation and fog will usually disappear
in a few minutes). The moisture can cause
lint, dust and other airborne particles to cling
to the glass surface.
• Initial curing of the high temperature paint
and burning off of lubricants used in the
manufacturing process may result in a fi lm
on the glass.
• A white coating may form on the glass as a
result of impurities and minerals in the fuel.
It is recommended that the glass be cleaned
two or three times during each heating season,
depending on the circumstances present. The
following cleaning solutions are approved for use
to clean glass:
• Non-ammonia based household cleaner
• 50%-50% mix of white vinegar & water
• Gas fi replace/stove glass cleaner
Inspect Glass Gasket - Visually inspect the
gasket on the backside of the glass enclosure
panels. The gasket surface must be clean, free
of irregularities and seated fi rmly.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
IMPORTANT
Clean 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 im-
proper handling and need replacement, use only
the proper replacement logs from manufacturer
(see Pages 25 & 26 for ordering information).
Re-Install Embers, Logs and Vermiculite
- Carefully follow placement instructions on
Pages 8 to 10). 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 13.
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.
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) Wall Thermostat,
Remote Control or Remote Wall Switch Kit
Inspect Burner Flame Appearance
Ensure that the burner flame appearance
resembles the fl ame shown in Figures 10 &
11 and as described in Flame Appearance and
Sooting on Page 11. 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 4). If the surface later becomes stained
or marred, it may be lightly sanded and touched
up with spray paint.
