Burn-in Period

During the first few fires of this appliance there
will be some odor due to the curing of the
paint and burning off of lubricants used in the
manufacturing process. Depending on your
use, the burn-in period may take a few hours
or a few days.

KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED DURING THE CURING
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.

NOTICE: A white film may develop

on the glass enclosure panel during
the first few fires as part of the burn-in
process.

The first few times you use the
fireplace, clean the glass after each use
(AFTER THE GLASS HAS COMPLETELY
COOLED); otherwise, the white film
will bake onto the glass and become
difficult to remove.

MAINTENANCE

(See Maintenance Schedule, Page 19)

Refer to the maintenance schedule for
maintenance tasks, procedures, frequency and
by whom they should be performed. Always
verify proper operation of the appliance after
servicing.

WARNING

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 adé­quatement une fois l'entretien terminé.

Before re-lighting the fireplace, refer
to the lighting instructions in this
manual. Instructions are also found on
pull-out panels 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 techni­cian (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.

Glass Cleaning

(See Front Glass Enclosure Panel, Removal and
Installation on Page 9).

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 clean­ers on glass. Never clean the glass when
it is hot.

The viewing glass should be cleaned periodi­cally to remove any build-up caused from the
following:

• During start-up, it is normal for condensa­tion 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 & water

• Gas 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 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 han­dling 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).

Replacing Logs

If the logs become damaged by accident or
improper handling and need replacement, use
only the proper replacement logs from manu­facturer (see Pages 22 and 23 for ordering
information).

Re-install Embers, Volcanic stone and Logs

Carefully follow placement instructions on
Pages 10 and 11). All logs should fit onto
corresponding pins and/or log stoppers. This
will ensure a proper flame and safe combustion.

Inspect Wiring

Refer to wiring diagrams on Page 14.

CAUTION: Label all wires prior to discon­nection 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 fonctionnement
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

Inspect Burner Flame Appearance

Ensure that the burner flame appearance
resembles the flame shown in Figures 13 or

14 and as described in Flame Appearance and
Sooting on Page 12. 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 touch­ups. 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.

BURNER ADJUSTMENTS

(QUALIFIED TECHNICIANS ONLY)

Flame Appearance and Sooting

Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
gradually turn yellowish-orange during the first
15 minutes of operation. After 15 minutes of
operation, if the flame is blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.

If the air shutter opening is closed too far,
sooting may develop. Sooting is indicated by
black puffs developing at the tips of very long
orange flames. Sooting results in black deposits
forming on the logs, appliance inside surfaces
and on exterior surfaces adjacent to the vent
termination. Sooting is caused by incomplete
combustion in the flames and lack of combustion
air entering the air shutter opening. To achieve
a warm yellowish-orange flame with an orange
body that does not soot, the shutter opening
must be adjusted between these two extremes.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, rst

check the log set positioning to ensure that
the flames are not impinging on any of the
logs. If the log set is properly positioned
and a sooting condition still exists, then the
air shutter opening should be increased.

• The more offsets in the vent system, the larger

the air shutter opening will need to be.

• An appliance operated with the air shutter

opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.

• Propane models may exhibit ames which

candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
closed position, then operate the appliance
for a few more minutes to ensure that the
flame normalizes and the flames do not
appear sooty.
