2. During the first initial burns of these appli-
ances, there will be some odor emitted (see
Burn-In Period on Page 3 ).
inspect Venting system
clean Logs and Burner
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).
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.
3. Keep the lower control compartment clean
by vacuuming or brushing at least twice
a year. More frequent cleaning may be
required due to excessive lint from carpet-
ing, bedding materials, pet hair, etc. it is
veryimportantthatcontrolcompartments,
burners, circulating air passageways
and air venturi on the appliance are not
obstructed in any way.
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.
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 Pages 26 & 27 for ordering information).
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.
cleaning Glass
(seeFrontGlassEnclosurePanel, Removaland
Installation on Page 6 )
re-install embers and Logs - Carefully follow
placement instructions on Pages 7 to 9 ). All
logs should fit onto corresponding pins and/or
log stoppers. This will ensure a proper flame
and safe combustion.

Refer to wiring diagrams on Page 12.
5. Always keep the appliance area clear and
free from combustible materials, gasoline
and other flammable liquids.
WarninG: Label all wires prior
to disconnection when servicing
controls. Wiring errors can cause
improper and dangerous opera-
tion. Verify proper operation after
servicing.
The viewing glass should be cleaned periodi-
cally to remove any build-up caused from the

Maintenance
(see Maintenance schedule, Page 22)
Refertothemaintenancescheduleformaintenance
tasks, procedures, periodicity and by whom they
shouldbeperformed. Alwaysverifyproperopera-
tion of the appliance 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
• 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, 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.
WarninG: turn off gas and elec-
trical power before servicing the
appliance.
inspect Burner Flame appearance
Ensure that the burner flame appearance
resembles the flame shown in Figures 9 &
10 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.
• A white coating may form on the glass as a
result of impurities and minerals in the fuel.
caution: Wearglovesandsafety

required maintenance.
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
iMportant: always verify proper
operation after servicing.

fireplace.
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 Glass Gasket - Visually inspect the
gasket on the backside of the glass enclosure

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 9 - Burner Flame appearance Model sLdVt-35
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.
Figure 10 - Burner Flame appearance Model sLdVt-40
• 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.
4. Leave the control knob (off/pilot/on) in the
Burner air shutter adjustment procedure
ON position and the burner OFF/ON switch
OFF (& remote switches, if applicable).
5. When satisfied that the burner flame ap-
pearance is normal, close the lower control
compartment door.
1. Locateadjustmentrodandadjustairshutter
to the standard setting as shown in Figure
11 (adjustment rod is located in the lower
control compartment). Note: Rotating the
adjustment rod clockwise decreases air and
counterclockwise increases air.
2. Lightappliance(followlightingprocedureon
lighting label in control compartment or see
homeowners manual).
3. Allowtheburnertooperateforatleast15min-
utes while observing the flame continuously
to ensure that the proper flame appearance
has been achieved (see Figure 9 or 10). If
the following conditions are present, adjust
accordingly.
• Propane models may exhibit flames which
candle or appear stringy. If this is present and
persists, adjust the air shutter to a more open
position, then operate the appliance for a few
moreminutestoensurethattheflamenormal-
izes and the flames do not appear sooty.
WarninG: air shutter adjust-
ment should only be performed by
a qualified professional service
technician.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

Qualified Service Technician
Refer to Figure 12 (SIT Millivolt) or Figure 13 (Electronic) on
Page 11. Remove any surface build-up on pilot and burner
assembly. Wipe the pilot nozzles, igniter/flame rod and hood.
Ensure the pilot flame engulfs the flame sensor as shown.
Inspect the vent system at the top and at the base (within the
firebox) for signs of blockage or obstruction. Look for any signs
of dislocation or deterioration of the vent components. Note:
Excessive condensation can cause corrosion of caps, pipe &
fittings (excessive condensation can be caused by long lateral
runs, too many elbows and/or exterior portions of the system
being exposed to cold weather). Also inspect wall straps or
plumbers's tape to ensure it is secure and in place.
