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.
3. Keep the lower control compartment clean
by vacuuming or brushing at least twice a
year. Morefrequentcleaningmayberequired
duetoexcessivelintfromcarpeting,bedding
materials, pet hair, etc. it is very important
that the control compartments, burners
and circulating air passageways of the
appliance are kept clean.
4. Always turn off gas to the pilot (millivolt
appliances) and let the appliance cool down
before cleaning. Before re-lighting, refer
to the lighting instructions in this manual.
Lighting instructions may also be found
on the pull out lighting instruction labels
attached to the gas control valve.
5. Always keep the appliance area clear and
free from combustible materials, gasoline
and other flammable liquids.
6. Remember,Millivoltapplianceshaveacontinu-
ousburningpilotflame. Exercisecautionwhen
using products with combustible vapors.
clean Logs and Burner
Carefully remove the logs (use care when han-
dlingthefiberlogs,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 -
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.
If the logs become damaged by accident or im-
proper handling and need replacement, use only
the proper replacement logs from manufacturer
(see Pages 26 & 27 for ordering information).
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.

• Terminals at the Valve
• OFF/ON Switch
• (Optional Control Switch) Wall Thermostat,

• During start-up, it is normal for condensa-

condensation and fog will usually disappear
in a few minutes). The moisture can cause
lint, dustandotherairborneparticlestocling
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 Burner Flame appearance
iMportant
always verify proper operation
after servicing.
Ensure that the burner flame appearance
resembles the flame shown in Figures 10 &
11 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.
Before re-lighting the fireplace, refer to the
lighting instructions in this manual. instruc-
tions are also found on pull-out panels
located below the glass door 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).
Do not attempt to repaint the appliance until the

These are direct-vent appliances. They are
designed to operate only when the front glass
enclosure panel is installed. Generally the front
glass enclosure panel should not be removed
except to gain access to the components within
the firebox, and the appliance may only be op-
erated without the front glass enclosure panel
in place for very brief periods of time during
appliance checkout and adjustment. Note: The
flame appearance will be diminished while the
front glass enclosure panel is removed.

Flame appearance and sooting
Proper flame appearance is a flame which is
blueatthebaseandbecomesyellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
graduallyturnyellowish-orangeduringthefirst
15 minutes of operation. If after a short 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.
Iftheairshutteropeningsclosedtoofar,sooting
maydevelop.Sootingisindicatedbyblackpuffs
developingatthetipsofverylongorangeflames.
Sootingresultsinblackdepositsformingonthe
logs, appliance inside surfaces and on exterior
surfacesadjacenttotheventtermination. Soot-
ing is caused by incomplete combustion in the
flames and lack of combustion air entering the
air shutter opening. To achieve a warm yellow-
ish-orangeflamewithanorangebodythatdoes
not soot, the shutter opening must be adjusted
between these two extremes.
Figure 10 - Burner Flame appearance Model LMdV-3328 & LMdV-3530
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.
• Themoreoffsetsintheventsystem,thelarger
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.

Burner air shutter adjustment procedure
5. When satisfied that the burner flame ap-
pearance is normal, close the lower control
compartment door.
• Propane models may exhibit flames which
candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
openposition, thenoperatetheappliancefor
a few more minutesto ensure that the flame
normalizes and the flames do not appear
sooty.
1. Locateadjustmentrodandadjustairshutter
to the standard setting as shown in Figure
12 (adjustment rod is located in the lower
control compartment). Note: Rotating the
adjustment rod clockwise decreases air and
counterclockwise increases air.
2. Lightappliance(followlightingprocedureon

homeowners manual).
3. Allowtheburnertooperateforatleast15min-
utes while observing the flame continuously

has been achieved (see Figure 10 or 11). If
the following conditions are present, adjust
accordingly.
