VENT OPERATION TEST
A vent operation test is required as part of the
installation to verify that proper venting conditions exist and should be done periodically to
ensure nothing has changed that would affect
proper venting of the appliance.
Procedure:
1. ENSURE APPLIANCE IS OFF (PILOT ONLY)
AND COOL.
2. Open both latches on one of the glass
enclosure doors and slightly prop it open at
the bottom (approx. 1/4” gap). See Figure
6 on Page 12.
3. Turn on all the exhaust fans in the dwelling
(and any other appliances which remove
air from the dwelling, such as a furnace or
clothes dryer, etc.).
4. Ensure that all the doors and windows in
the room where the fireplace is located are
closed.
5. Light the appliance (see Lighting Instruc-
tions, Pages 22 to 25). Adjust flame height to
highest setting and operate for approximately
5-10 minutes. Do not leave appliance unattended.
6. Take a smoke producing device and move it
along the bottom edge of the glass door (where
it is cracked open). If smoke is drawn into the
firebox, the vent operation is adequate.
IF THE SMOKE IS NOT DRAWN INTO
THE FIREBOX, TURN THE APPLIANCE
OFF AND CALL A QUALIFIED SERVICE
TECHNICIAN.
SPILL SWITCH OPERATION
Manual-Reset (safety limit) Spill Switch
This appliance is equipped with a (safety limit)
spill switch that is designed to "trip" and discon-
nect the burner circuit if flue spillage occurs
(because of improper venting of combustion
products or vent blockage). If, during appliance
operation, the burner flame goes out (independently of the burner OFF/ON wall switch), it may
be due to the operation of this (safety limit) spill
switch. If this switch "trips" it will need to be
manually reset by pressing the reset button on
switch (see Figure 4).
Procedure to Reset (safety limit) Spill Switch
ALLOW APPLIANCE TO COOL COMPLETELY
BEFORE ACCESSING AND RESETTING
To access the spill switch:
1. Pull off the top louvered panel.
2. Locate and press the red reset button on

Outside Combustion Air Controls
Many appliances are equipped, when installed,
with an outside (make-up air) vent system
that is designed to provide the appliance with
outside make-up air for combustion when in
operation.
The outside air control lever for the outside
air system is standard on all appliances but
should not be operated if the complete system
is not installed. Refer to Figure 5. When the
complete outside air vent system is installed,
the installer will remove the securing screw
from the combustion air control lever located
on the right side of the fireplace opening.
If the securing screw has not been removed
and you have reason to believe that you have
a complete outside air system, contact your
distributor to have your appliance inspected for
the presence of the complete system. DO NOT
assume that you have this system in place.
WARNING
Do not operate the shutoff lever
unless a complete outside combustion air system has been
installed with your appliance.
To open the outside air shutter, open the bottom
control access panel, and pull the outside air
control lever all the way out. The outside air
shutter should be fully open when the fireplace
is in use and completely closed when the fireplace is not being used. Closing it when not in
use will prevent outside cold air from entering
the dwelling.
The hand operated outside air control lever is
located on the right side of the fireplace opening. See Figure 5.
To open the outside air , open the bottom control access panel, reach into the gap between
the firebox bottom and pull the outside air
control lever all the way out.
The outside air shutter should be fully open when
the fireplace is in use and completely closed
when the fireplace is not being used. Closing
it when not in use will prevent outside cold air
from entering the dwelling.
Operate the actuator through several cycles
including the closed position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the closed position.

MAINTENANCE
(See Maintenance Schedule, Page 26)
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 fireplace 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 relighting, refer to the lighting instructions
in this manual. Instructions are also found
on a pull-out panel located 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 technician
(inspection should include ensuring that exhaust
passage is unobstructed and vent components
are properly assembled and not damaged).
Homeowner must contact a qualified service
technician at once if any abnormal condition
is observed.
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 10)
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 a dry, soft towel as desired. Take
care not to scratch the glass surface.
IMPORTANT: 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 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 and water
• Gas 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 firmly.
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 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.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Replacing Logs
If the logs become damaged by accident or
improper handling and need replacement,
use only the proper replacement logs from
manufacturer (see Page 29 for ordering
information).
Re-Install Embers, Logs and Vermiculite
Carefully follow placement instructions on
Pages 12 to 15). All 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 Page 17.
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
• OFF/ON Switch
• (Optional Control Switch) Remote Control
or Remote Wall Switch Kit
Inspect Burner Flame Appearance
Ensure that the burner flame appearance
resembles the flame shown in Figure 15 and
as described in Flame Appearance and Sooting
on Page 15. The Homeowner must contact
a qualified service technician at once if any
abnormal condition is observed.
Small Area Paint Touch-up
Only use a factory supplied paint kit for touchups. Paint is available at your local authorized
Lennox Hearth Products dealer. Never attempt
to paint a hot fireplace.
If the surface later becomes stained or marred,
it may be lightly sanded and touched up with
spray paint.

Flame Appearance and Sooting
Proper flame appearance is a flame which is
E
D
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. After 15 minutes of
operation, if the flame is 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 opening is 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.
Air Shutter Adjustment Guidelines
• If there is smoke or soot present, rst
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.
• If there are offsets in the vent system, the air
shutter opening may need to be increased.
• 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.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
• 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.

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 Figure 15). If the
following conditions are present, adjust
accordingly.
• If ame appears weak or sooty, adjust
the air shutter, incrementally, to a more
open position until the proper flame
appearance is achieved.
• If ame 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 (and remote switches, if applicable).
5. When satisfied that the burner flame appear-
ance is normal, close the lower control

TROUBLESHOOTING THE MILLIVOLT CONTROL SYSTEM
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.
SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION
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.
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, the standard burner
OFF/ON switch on appliance must
be in the "OFF" position.
*Optional remote switch kits - wall
switch 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. Manual Reset Spill Switch has Tripped or is
defective.
B. Wall switch or wires defective. Check wall switch and wires for proper connections.
C. Thermopile may not be generating suf-
ficient millivolts.
D. Plugged burner orifice. Check burner orifice for blockage and remove.
E. 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 (igniter rod) and pilot –
should be 1/8" to have a strong spark. If gap measures
1/8", replace pilot (see Figure 17 on Page 16).
as marked on the rating plate.
Check pilot flame, it must impinge on thermocouple
(see Figure 17 on Page 16). Clean and/or adjust pilot
for maximum flame impingement on thermocouple.
Ensure that the connection between the valve and
thermocouple are tight and secure.
Follow Manual Reset procedure on Page 9. Once the
red reset button is fully depressed and clicks in, check
continuity with a multimeter between switch terminal
(Ohms). If it shows an open circuit, replace switch.
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 drainage) and the burner may not come on.
Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (see Figure 17 on
Page 16).
TROUBLESHOOTING GUIDE - ELECTRONIC IGNITION SYSTEM
SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION
1. Burner will not light. 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.” A. Burner orifice plugged. Check main burner orifice(s) for blockage. Clean
or replace.
B. Obstructed vent system. Check vent system for obstructions.
