DV GAS FIREPLACES (LSM40/45MN-2, LSM40/45MP-2, LSM40/45EN-2) • CARE AND OPERATION INSTRUCTIONS
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 & 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 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
improper handling and need replacement, use
only the proper replacement logs from manu-
facturer (see Pages 25 and 26 for ordering
information).
Re-install Embers, Vermiculite, Volcanic
stone and Logs
Carefully follow placement instructions on
Pages 11 and 12). 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 15.
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 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 and
14 and as described in Flame Appearance and
Sooting on Page 13. 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.
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. 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 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.
