MAINTENANCE
(See Maintenance Schedule, Page 24)
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.
Replacing Logs
If the logs become damaged by accident or
improper handling and need replacement,
use only the proper replacement logs from
manufacturer (see Page 26 for ordering
information).
Re-Install Embers and Logs
Carefully follow placement instructions on
Pages 13 through 16. All logs should fit
onto corresponding pins and/or log stop-
pers. This will ensure a proper flame and safe
combustion.
Inspect Wiring
Refer to wiring diagram on Page 19.
CAUTION: Label all wires prior to discon-
nection when servicing controls. Wiring
errors can cause improper and dangerous
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 14
through 16 and as described in Flame Appear-
ance and Sooting on Page 17. The Homeowner
must contact a qualified service technician at
once if any abnormal condition is observed.
Small Area Paint Touch-up
The finish 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. Never attempt to
paint a hot fireplace.
Do not attempt to repaint the appliance until
the finish is completely cured (see Burn-In
Period on Page 7). If the surface later becomes
stained or marred, it may be lightly sanded and
touched up with spray paint.
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.
Before re-lighting the fireplace, 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 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
(see Front Glass Enclosure Panel, Removal and
Installation on Page 12).
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 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:
IMPORTANT: Do not use abrasive clean-
ers 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 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 Logs And Burner
Carefully remove the logs (use care when han-
dling the fiber 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.
WARNING
Turn off gas and electrical power
to the fireplace and allow it to
cool before cleaning or servicing
the appliance.
