MAINTENANCE

(See Maintenance Schedule, Page 25 )
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 fi replace 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.
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 on the fl oor of the
appliance.
Always keep the appliance area clear and
free from combustible materials, gasoline
and other fl ammable liquids.
Remember, Millivolt appliances have a
continuous burning pilot fl ame. Exercise
caution when using products with
combustible vapors.
Inspect Venting System
The appliance and venting system should
be thoroughly inspected before initial use
and at least annually by a qualifi ed 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 qualifi ed
service technician at once if any abnormal
condition is observed.
If the venting system is disassembled for any
reason, a qualifi ed 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.

® DIRECT VENT GAS FIREPLACES (MPD33/35/40/45) • CARE AND OPERATION INSTRUCTIONS
Cleaning Glass
(see Front Glass Enclosure Panel, Removal
and Installation on Page 11).
Note: Clean glass after fi rst two weeks of
operation (after Burn-In period is over) and
then only when necessary and when the
fi replace is cool. Wipe surface with a clean,
dampened, soft cloth. Follow with a dry, soft
towel as desired. Take care not to scratch the
glass surface.
WARNING: 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
fi lm 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 fi 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 fi rmly.
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 fi ber 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
manufacturer (see Pages 13,14 and 15 for
ordering information).
Reinstall Embers and Logs
Carefully follow placement instructions
on Pages 12 through 15. All logs should
fi t onto corresponding pins and/or log
stoppers. This will ensure a proper fl ame
and safe combustion.
Inspect Wiring
Refer to wiring diagrams on Page 18.
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
• CPI Switch (Pilot Mode)
• (Optional Control Switch) Wall
Thermostat, Remote Control or Remote
Wall Switch Kit
Inspect Burner Flame and Pilot Flame
Appearance
Periodically do a visual check of the burner
and pilot fl ames.
See Burner Flame Appearance on Page 16.
See Pilot Flame Appearance on Page 17.
Contact a qualifi ed 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
Lennox Hearth Products dealer. Never
attempt to paint a hot fi replace.
Do not attempt to repaint the appliance until
the fi nish is completely cured (see Burn-In
Period on Page 4). If the surface later
becomes stained or marred, it may be lightly
sanded and touched up with spray paint.
