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.
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 an electronic
intermittent pilot system provides safe, efficient
operation. 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-31-5) to
ANSI ZZ21.88b-2003 (in Canada, CSA-2.33b2003), 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,
CSA C22.1 - latest editions.

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.
Test gauge connections are provided on the
front of the millivolt gas control valve, identified
IN for the inlet and OUT for the manifold side
(see Figures 4 or 5 on Page 5 ). A 1/8" NPT
Test gauge connection is provided at the inlet
and outlet (manifold) ports on the electronic gas
control valve (see Figure 3 on Page 5 ).
Depending on your use, the burn-in period may
take a few hours or a few days.
These appliances must be isolated from the
gas supply piping system (by closing their
individual manual shut-off valve) during any
pressure testing of the gas supply piping
system at test pressures equal to or less than
1/2 psig (3.5 kPa).
These appliances and their individual shut-off
valves must be disconnected from the gas
supply piping system during any pressure
testing of that system at pressures greater
than 1/2 psig (3.5 kPa).
If an optional blower is installed, Do not turn it
on during the Burn-In period.
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 ).
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.
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).

Inspect Venting System
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician
(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.
5
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.
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 22 & 23 for ordering information).
Cleaning Glass
(see Front Glass Enclosure Panel, Removal
and Installation on Page 7) 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.
Inspect Wiring
Refer to wiring diagrams on Page 13.
The viewing glass should be cleaned periodically 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 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 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 handling 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.
6
Re-Install Embers, Logs and Vermiculite
- Carefully follow placement instructions on
Pages 8 to 10 ). All logs should fit onto corresponding pins and/or log stoppers. This will
ensure a proper flame and safe combustion.
WARNING
Label all wires prior to disconnection when servicing 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 10 &
11 and as described in Flame Appearance and
Sooting on Page 11. 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 (cat. no. 90L74). 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.
Front Glass Enclosure Panel, Removal

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 operated 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.
During this appliance checkout and adjustment period, a potential safety hazard exists
- EXERCISE EXTREME CAUTION to prevent
the occurrence of any burn injuries from the
exposed flames or hot surfaces. Also note, that
while the front glass enclosure panel (or any of
the panels) is removed, the flame appearance
will appear to be smaller than normal.

not use all that is in a new bag at one time. For
best glowing effect, replace the ember material
annually.
6. Placement of Logs and Twigs All logs that have locating notches or slots to
help ensure that they are properly positioned.
All top logs that rest on lower logs, do so
over notches, indents or pins. Proper twig
placement is critical to prevent sooting. Twigs
should be placed in the gaps between the flame
peaks and should be positioned so they do not
impinge the flames.

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. Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the
air shutter opening. To achieve a warm yellowish-orange flame with an orange body that does
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.
Figure 11 - Burner Flame Appearance Model LMDV-4035
• 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
normalizes 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.
Air Shutter Adjustment Guidelines:

Burner Air Shutter Adjustment Procedure
1. Locate adjustment rod and adjust air shutter
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. Light appliance (follow lighting procedure on
lighting label in control compartment or see
homeowners manual).
3. Allow the burner to operate for at least 15 minutes while observing the flame continuously
to ensure that the proper flame appearance
has been achieved (see Figures 10 or 11). If
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.
4. Leave the control knob (off/pilot/on) in the
ON position and the burner OFF/ON switch
OFF (& remote switches, if applicable).
5. When satisfied that the burner flame appearance is normal, close the lower control
compartment door.
WARNING
Air shutter adjustment should
only be performed by a qualified
professional service technician.
WARNING
Ensure front glass panel is in place
and sealed during adjustment.
CAUTION
Carbon will be produced if the air
shutter is closed too much. Any
damage due to carboning resulting from improperly setting the
air shutter is not covered under
the warranty.

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
1. Spark igniter will not light pilot after
repeated triggering of igniter button.
2. Pilot will not stay lit after
carefully following the lighting
instructions.
CORRECTIVE ACTION
A. Defective igniter
(no spark at electrode).
Check for spark at electrode and pilot; if no spark and
electrode wire is properly connected, replace igniter.
B. Defective or misaligned electrode at pilot
(spark at electrode).
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 Figures 13 or 14 on Page 12).
C. Gas supply pressure errant.
Check inlet gas pressure. It should be within the limits
as marked on the rating plate.
D. Pilot orifice plugged.
Clean or replace pilot orifice.
A. Defective pilot generator
(thermocouple).
Check pilot flame, it must impinge on thermocouple
(see Figures 13 or 14 on Page 12). Clean and/or
adjust pilot for maximum flame impingement on
thermocouple. Ensure that the connection between
the valve and thermocouple are tight and secure.
3. Pilot burning, no gas to burner, Valve A. Wall switch or wires defective.
knob “ON,” and the (standard) burner
OFF/ON switch is “ON." Read important note below.
Check wall switch and wires for proper connections.
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.
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.
B. Thermopile may not be generating sufficient millivolts.
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.
C. Plugged burner orifice.
Check burner orifice for blockage and remove.
*Optional remote switch kits - wall
switch, wall thermostat or remote
control.
D. OFF/ON Switch & *Remote Switch are in
the "ON" position resulting in excessive
resistance.
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 drainage) and the burner may not come on.
A. Pilot flame may be too low or blowing (high)
causing the pilot/valve safety to drop out.
Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (see Figures 13 or
14 on Page 12).
4. Frequent pilot/burner outage problem.
TROUBLESHOOTING GUIDE - ELECTRONIC IGNITION SYSTEM
SYMPTOM
1. Burner will not light.
POSSIBLE CAUSES
CORRECTIVE ACTION
A. Faulty Valve System.
See Below.
B. “OFF/ON” or wall switch defective.
Disconnect the two black wires from the wire nuts.
Test switch(s) for continuity with a multimeter. If
continuity is not indicated, switch(s) is defective and
must be replaced.
Note: Before replacing “OFF/ON” switch, Ensure to
check wiring for loose connections or broken wires
and repair as needed.
2. Burners come “ON,” then turns “OFF.”
