IMPORTANT
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,dustand other airborneparticlesto 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 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.
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 flame shown in Figure 13 and
as described in Flame Appearance and Sooting
on Page 10.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
availableatyourlocalauthorizedLennoxHearth
Productsdealer, cat.no.90L74. Never attempt
to paint a hot fireplace.
Do not attempt to repaint the appliance until the
finish is completely cured (see Burn-In Period
onPage 4). Ifthesurfacelaterbecomesstained
ormarred,it may belightlysanded and touched
up with spray paint.
Clean Logs And Burner
Carefully remove the logs (use care when han-
dlingthe fiberlogs,astheybecomequitefragile
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
onlytheproperreplacementlogsfrommanufac-
turer (see Page 24 for ordering information).
Re-Install Embers, Logs and Vermiculite
- Carefully follow placement instructions on
Pages 8 to 10). All logs should fit onto cor-
responding pins and/or log stoppers. This will
ensure a proper flame and safe combustion.

WARNING
This appliance is not designed
to burn wood. Any attempt to
do so could cause irreparable
damage to appliance and prove
hazardous to your safety.
WARNING
Iflogs are not installed according
totheloginstallationinstructions,
flameimpingementandimproper
combustioncouldoccurandresult
in soot and/or excessive produc-
tion of carbon monoxide (CO), a
colorless, odorless, toxic gas.
WARNING
Logs get very hot and will remain hot up to one hour after gas supply is
turned off. Handle only when logs are cool. Turn off all electricity to the
appliance before you install grate and logs.
BURNER ADJUSTMENTS (QUALIFIED TECHNICIANS ONLY)
If the air shutter openings 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, first 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 flames 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.
Flame Appearance & 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 gradu-
ally turn yellowish-orange during the first 15 minutes of operation. If after period the flame stays
lowered blue, or if the flame is orange with evidence of sooting (black tip), the air shutter opening
may need to be adjusted.

3. Allowtheburnertooperateforatleast15min-

has been achieved (see Figure 13). If the
following conditions are present, adjust
accordingly.
• If flame appears weak or sooty, adjust
theair shutter,incrementally,to amore
open position until the proper flame
appearance is achieved.
• If flame stays lowered blue, adjust the
air shutter, incrementally, to a more
closed position until the proper flame
appearance is achieved.
4. Leave the control knob (off/pilot/on) in the
