MAINTENANCE

(See Maintenance Schedule, Page 24)
Refer to the maintenance schedule for mainte-
nance tasks, procedures, frequency and by whom
they should be performed. Always verify proper
operation of the appliance after servicing.

Turn off gas and electrical power
to the fireplace and allow it to
cool before cleaning or servicing
the appliance.
CAUTION: Wear gloves and safety
glasses for protection while doing
required maintenance.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adé-
quatement une fois l'entretien terminé.
Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-
lighting, refer to the lighting instructions
in this manual. Instructions are also found
on a pull-out panel located 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 qualified service techni-
cian (inspection should include ensuring that
exhaust or intake passages are unobstructed
and vent components are properly assembled
and not damaged). Homeowner must contact
a qualified service technician at once if any
abnormal condition is observed.
If the venting system is disassembled for any
reason, a qualified 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.

Cleaning Glass
(Also see Front Glass Enclosure Panel, Removal
and Installation on Page 11.)
Note: Clean glass after first two weeks of opera-
tion (after Burn-In period is over) and then only
when necessary and when the fireplace is cool.
Wipe surface with clean, dampened, soft cloth.
Follow with a dry, soft towel as desired. Take
care not to scratch the glass surface.
IMPORTANT: Do not use abrasive clean-
ers on glass. Never clean the glass when
it is hot.
The viewing glass should be cleaned periodi-
cally to remove any build-up caused from the
following:
• 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 film
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 and water
• Gas fireplace/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 firmly.
Clean Control Compartment
Keep 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, etc. It is
important that control compartments, burners
and circulating air passageways of the appliance
be kept clean.
Clean Sub-Floor And Burner
Carefully remove the contemporary media
covering the firebox sub-floor. Place it in a
container for future use. Vacuum out any
foreign matter (lint, carbon, etc.) on the burner.
Ensure the burner ports are "open." Remove
any carbon deposits from the burner outlet
using a vacuum cleaner, or a soft bristled
brush (i.e. paint brush).
Replacing Contemporary Media
Replace the contemporary media previously
removed. See Pages 12 and 13. Use only
the proper replacement materials from the
manufacturer (see Pages 19 and 27 for order-
ing information).
Note: Improper positioning of media can create
carbon build-up and will alter the performance
of the appliance.
Inspect Wiring
Refer to wiring diagrams on Page 16.
CAUTION: When servicing controls, label
all wires prior to disconnection. Wiring
errors can cause improper and danger-
ous operation. Verify proper operation
after servicing.
ATTENTION: Au moment de l'entretien
des commandes, étiquetez tous les fils
avant de les débrancher. Des erreurs
de cáblage peuvent entraîner un fonc-
tionnement inadéquat et dangereux.
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 flame shown in Figures 6 and
7 on Pages 13 and 14 and as described in
Flame Appearance and Sooting on Page 14. The
Homeowner must contact a qualified service
technician at once if any abnormal condition
is observed.
Small Area Paint Touch-up
Only use a factory supplied paint kit for touch-
ups. Paint is available at your local authorized
Lennox Hearth Products dealer. Never attempt
to paint a hot fireplace.
If the surface later becomes stained or marred,
it may be lightly sanded and touched up with
spray paint.
