INTRODUCTION
The Fireplace models covered in this manual
are Direct-Vent sealed combustion gas fireplace
heaters designed for residential application.
Direct-Vent appliances operate with the combustion chamber completely isolated from the
indoor environment.
All air for combustion is brought in from the
outside and exhaust gases are vented through
the same direct vent, co-axial (intake/exhaust)
vent system.
2
The Millivolt appliances have a millivolt gas
control valve with piezo ignition system provides
safe, efficient operation. If any optional accessories which require electrical power are being
installed, the electrical power must be provided
at the time of appliance installation.
The Electronic appliances have a battery backed
up electronic intermittent pilot system that
provides safe, efficient operation. No external
electrical power is required to operate these
appliances.
These appliances comply with National Safety
Standards and are tested and listed by OmniTest Laboratories (Report No. 116-F-50-5)
to ANSI ZZ21.88 (in Canada, CSA-2.33), and
CAN/CGA-2.17-M91 in both USA and Canada,
as vented gas fireplace heaters.
The Installation must conform to local codes
or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1/NFPA
54-latest edition, or the Natural Gas and
Propane Installation Code, CSA B149.1-latest
edition. The appliance, when installed, must
be electrically grounded in accordance with
local codes or, in the absence of local codes,
the latest edition of the National Electrical Code,
ANSI/NFPA 70, or the Canadian Electrical Code,

Orifice Sizes - Sea Level to High Altitude
(All Models): These appliances are tested and
approved for installations at elevations of 0-4500
feet (0-1372 meters) above sea level using the
standard burner orifice sizes (marked with an
"*" in Table 7).
At the time of installation, it must be determined
if the appliance needs to be derated. Contact
your local gas supplier for deration requirements
for your area.
Deration - At higher elevations, the amount of
BTU fuel value delivered must be reduced by
either using gas that has been derated by the gas
company or by changing the burner orifice to a
smaller size as regulated by the local authorities
having jurisdiction and by the (USA) National
Fuel Gas Code NFPA 54/ANSI Z223.1 - latest
edition or, in Canada, the CAN1-B149.1 and .2
codes - latest edition.
Burn-in Period
During the first few fires of this appliance there
will be some odor due to the curing of the
paint and burning off of lubricants used in the
manufacturing process.
Depending on your use, the burn-in period may
take a few hours or a few days.
KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED DURING THE CURING
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.
If an optional blower is installed, Do Not turn
it on during the Burn-In period.
A white film may develop on the glass front
during the first few fires as part of the curing
process. The glass should be kept clean during
the first two weeks of use to prevent the film from
baking on (making it very difficult to remove).
See
Cleaning Glass on Page 5.

MAINTENANCE
(See Maintenance Schedule,
Refer to the maintenance schedule for maintenance
tasks, procedures, periodicity and by whom they
should be performed. Always verify proper opera
tion of the appliance after servicing.
Page 22)
WARNING: Turn off gas and electrical power before servicing the
appliance.
CAUTION: Wear gloves and safety
Glasses for protection while doing
required maintenance.
IMPORTANT: Always verify proper
operation after servicing.
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).
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.
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
Pages 26 & 27 for ordering information).
Re-Install Embers and Logs - Carefully follow
placement instructions on
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
WARNING: Label all wires prior
-
to disconnection when servicing
Pages 7 to 9 ). All
Page 12.
controls. Wiring errors can cause
improper and dangerous operation. Verify proper operation 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 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.
Small Area Paint Touch-up
The finish of the appliance is a high-quality powdercoat. Only use factory supplied
powdercoat paint kit for touch-ups. Paint is
available at your local authorized Lennox Hearth
Products dealer. 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.

BURNER ADJUSTMENTS
(QUALIFIED TECHNICIANS ONLY)
Flame Appearance and sooting
Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
gradually turn yellowish-orange during the first
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.
If the air shutter openings closed too far, sooting
may develop. Sooting is indicated by black puffs
developing at the tips of very long orange flames.
Sooting results in black deposits forming on the
logs, appliance inside surfaces and on exterior
surfaces adjacent to the vent termination. 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-orange flame with an orange body that does
not soot, the shutter opening must be adjusted
between these two extremes.
Air Shutter Adjustment Guidelines
Figure 9 - Burner Flame Appearance Model SLDVT-35
-
-
• 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.
• The more offsets in the vent system, the larger
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.
• 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
more minutes to ensure that the flame normal
izes and the flames do not appear sooty.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

3. Allow the burner to operate for at least 15 min
utes while observing the flame continuously
to ensure that the proper flame appearance
has been achieved (see
the following conditions are present, adjust
accordingly.
• If flame appears weak or sooty, adjust
the air shutter, incrementally, to a more
open position until the proper flame
appearance is achieved.
• If flame stays lowered blue, adjust the
air shutter, incrementally, to a more
closed position until the proper flame
appearance is achieved.

TROUBLESHOOTING
Note: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and wall switch, iff applicable), is
in the “ON” position.
Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
TROUBLESHOOTING GUIDE - MILLIVOLT GAS CONTROL SYSTEM
SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION
1. Spark igniter will not light pilot after
repeated triggering of igniter button.
WARNING: if the pilot will not light
after 1 minute of attempting, wait
for at least 5 minutes for gas to
clear before attempting again.
2. Pilot will not stay lit after
carefully following the lighting
instructions.
3. Pilot burning, no gas to burner, Valve
knob “ON,” and the (standard) burner
OFF/ON switch is “ON." Read important note below.
IMPORTANT NOTE: If an optional
*remote switch is used for burner
operation, if the standard burner
OFF/ON switch is still installed on
appliance it must be in the "OFF"
position.
*Optional remote switch kits - wall
switch, wall thermostat or remote
control.
4. Frequent pilot/burner outage prob-
lem.
A. Defective igniter
(no spark at electrode).
B. Defective or misaligned electrode at pilot
(spark at electrode).
C. Gas supply pressure errant. Check inlet gas pressure. It should be within the limits
D. Pilot orifice plugged. Clean or replace pilot orifice.
A. Defective pilot generator
(thermocouple).
A. Wall switch or wires defective. Check wall switch and wires for proper connections.
B. Thermopile may not be generating suf-
ficient millivolts.
C. Plugged burner orifice. Check burner orifice for blockage and remove.
D. OFF/ON Switch & *Remote Switch are in
the "ON" position resulting in excessive
resistance.
A. Pilot flame may be too low or blowing (high)
causing the pilot/valve safety to drop out.
Check for spark at electrode and pilot; if no spark and
electrode wire is properly connected, replace igniter.
Using a match, light pilot. If pilot lights, turn off pilot
and trigger the igniter button again. If pilot lights, an
improper gas mixture caused the bad lighting and a
longer purge period is recommended. If pilot will not
light – check gap at electrode and pilot – should be 1/8"
to have a strong spark. If gap measures 1/8", replace
pilot (see
as marked on the rating plate.
Check pilot flame, it must impinge on thermocouple
(see
adjust pilot for maximum flame impingement on
thermocouple. Ensure that the connection between
the valve and thermocouple are tight and secure.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch. If okay, jumper
wires across wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.
Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
325 millivolts minimum with optional wall switch
“OFF.” Replace faulty thermopile if reading is below
specified minimum.
When turning on the burner using a *remote switch,
ensure that the standard OFF/ON switch is in the "OFF"
position. If both switches are in the ON position, it
may result in excessive resistance (& millivolt drain
age) and the burner may not come on.
Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (see
13 on Page 12).
