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).
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.
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.
important: it is imperative that
the control compartment, burn-
ers and circulating air passage
ways of the appliance be kept
clean.
cleaning Glass
(see Front Glass Enclosure Panel, Removal and
Installation on Page 6 ). Note: Clean glass
after first two weeks of operation (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
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 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.
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.
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 Page 23 for ordering information).
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
re-install embers, Logs and Vermiculite
- Carefully follow placement instructions on
Pages 7 to 9 ). All logs should fit onto cor-
responding pins and/or log stoppers. This will
ensure a proper flame and safe combustion.
inspect Wiring
Refer to wiring diagrams on Page 11.
WarninG: Label all wires prior
to disconnection when servic-
ing controls. Wiring errors can
cause improper and dangerous
operation. Verify proper opera-
tion 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 19. 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 , 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
on Page 3 ). If the surface later becomes stained
or marred, it may be lightly sanded and touched
up with spray paint.
