ORIFICE SIZE/ALTITUDE ADJUSTMENT
For altitudes above 2,000 feet (In Canada 4,500 FT/1370 M),the orifice
should be de-rated by 4% for every 1,000 feet to maintain the proper
ratio of gas to air. Improper orifice sizing may result in damage and
unsafe conditions. Changing the orifice should only be done by a quali­
fied service technician. Contact your Lennox Hearth Products dealer for
proper orifice sizes.
SMOKE DETECTORS
Since there are always several potential sources of fire in any home, we
recommend installing smoke detectors. If possible, install the smoke
detector in a hallway adjacent to the room (to reduce the possibility of
occasional false activation from the heat produced by the appliance). If
your local code requires a smoke detector be installed within the same
room, you must follow the requirements of your local code. Check with
your local building department for requirements in your area.

Venting
This appliance can be vented with Secure Vent™ direct-vent pipe by Security
Chimneys™*. Coaxial pipe diameters are 6-5/8” outer and 4” inner. The
combustion air for this stove is drawn from outside the house through
the outer DV (direct-vent) pipe. Room air is not required for combustion.
When planning your installation, select the correct length of vent pipe
for your particular requirements. Determine the minimum clearance to
combustibles from the rear of the unit to the wall. It is also important
to note the thickness of the wall. Before cutting the vent hole through
the wall make sure that ALL vent and termination clearances (see Page
17) will be met.
Electrical
The standard fan motor requires 120 Volts AC for operation. The stove is
not dependent on the fan or an outside electrical supply to operate.
WARNING - Electrical Grounding Instructions - This appliance is
equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a
properly grounded three-prong receptacle. Do not cut or remove
the grounding prong from this plug.
* Other approved chimney brand is Simpson Dura-Vent DV-GS.
RATINGS

All installations using a vertical termination cap must maintain one inch
clearance between the direct-vent pipe and combustibles. For horizontal
runs of pipe, one inch of clearance to combustibles on the sides and
bottom and two inches on the top of the pipe is required. See Pages 14,
15 and 16 for allowable pipe configurations.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Clearances to Combustibles
Alcove dimensions
Minimum clearances to combustible materials shown here are in inches
(millimeters). See Pages 8 and 9 for pipe clearances.
The minimum width between alcove side walls is 30-1/2” (775mm). The
glass door lifts up to access the firebox on the stove. Therefore, if the stove
is to be installed in an alcove, the alcove needs to be constructed to allow
for removal of the glass door. Option 1: The maximum alcove depth is
15” (381mm) (maintaining a 4” [102mm] rear clearance the stove will be
positioned partly into the room) and the remaining minimum dimensions
to combustibles are as shown in the Option 1 drawing below. Option 2:
The alcove is 43” (1092mm) high to provide sufficient space to remove

Log Installation Instructions
If logs are not installed according to the log installation instructions, flame impingement and improper combustion could
occur and result in soot and/or excessive production of carbon
monoxide (CO), a colorless, odorless, toxic gas.
Figure 11
The size and position of the log set is critical to achieve a safe,
reliable and attractive flame pattern. Any attempt to use a different log set in the fireplace will void the warranty and will result
in incomplete combustion, sooting and poor flame quality.
Parts list: rear log, left front log, right front log and straight twig
1) Remove the logs from the box and carefully unwrap them. The logs
are fragile so handle them with care.
2) Align the holes in the bottom of the rear log (the longest log in the set)
with the two pegs just to the rear of the rear burner tube and slide the
log down onto the pegs (Figure 10). The charred black surface of the
log should face the front.
3) The left front log has two pegs protruding from the top surface (Figure 11). The charred black with white highlights surface of the log
should be facing forward. Slide this log down onto the left front and
center front pegs.
4) The right front log (positioned with the black charred surface towards
the front) should be placed on the peg protruding from the right end
of the left front log and the remaining peg at the right end of the metal
log support panel (Figure 11).
5) The remaining straight twig has two holes in the bottom. Position the
twig so the black and white charring is to the front and slide the holes
over the peg in the left front log and the peg in the rear log (Figure
12). It may be necessary to roll the top of the rear log slightly forward
to put this twig on the pegs.
6) Figure 13 shows the entire log set assembled. The embers provided
may be placed one high in front of the front burner tube using care not
to cover all the burner ports. Any extra embers may be placed at the
ends of the front log, off the burner. Place small pinches of rockwool
on top of the embers.

Side-Insert Installation
Follow these steps to install the cast iron inserts or your own custom
stone inserts in this appliance:
1. Remove the cast iron top and set it aside.
2. Remove the cast iron upper piece A - see Figure 14. Complete this step
by unscrewing the (2) 5/32 hex-head screws labeled B in Figure 17.
Lift out the upper cast piece A with the retaining bracket D attached.
3. Slide the cast iron or stone side inserts (size 15.5” x 10.5”) (with the
desired surface facing out) in behind the lower retaining bracket E. See
Figures 15, 16 and 17. Note that the cast iron inserts are reversible
- both sides have different designs.
4. Slide the heatshield (with the bent edges toward the cast or stone
inserts - Figure 15) in between the cast or stone insert and the lower
retaining bracket E.
5. Put the cast iron upper piece A back in its original location while
making sure that the upper retaining bracket D is to the inside of the
heatshield pushing it up firmly against the cast or stone insert - Figure

If you prefer, tile can be used as the top and side inserts. The top inserts
are 10-3/4” x 4-3/8” and the side inserts are 15-1/2” x 10-1/2”. The stove
can accommodate tile up to 1/2” thick. If 12” x 12” tile are used to make
the side inserts, a seam will result. The tile and the heatshield should be
positioned so the seam between the two pieces of tile is located between
the two bends on the heatshield (see Figure 18). Also note that the seam
and the heatshield can be rotated 180 degrees so the seam and the
heatshield bends are on the bottom.

Venting:
This appliance has been tested and listed as a direct-vent heater
system by OMNI-Test Laboratories, Portland, Oregon and is rec­
ommended for use with Security™ Secure Vent pipe*.
Horizontal Termination Kit which includes:
Important:
• Read all instructions carefully before starting the installation.
Failure to follow these instructions may create a fire or other
safety hazard and will void the warranty. Be sure to check for
specific clearances to combustible requirements on Page 9.
Do not extend the venting system vertically or horizontally in
excess of the distance prescribed on Page 16. Consult your
local building codes before beginning the installation.
• Always maintain the proper air spaces between the vent pipe
and nearby combustibles to prevent a fire hazard. Do not fill
air spaces with insulation. Be sure to check the vent termina­
tion clearance requirements from decks, windows, soffits, gas
regulators, air supply inlets and public walkways, as specified
in these installation instructions on Page 17 and local building
codes.
• This gas appliance and vent system must be vented directly
to the outside of the building and never be attached to a
chimney serving a separate solid fuel or gas-burning appliance. Each direct-vent gas appliance must use its own separate
vent system. Common vent systems are prohibited.
• This appliance is recommended for use with Security™ Secure
Vent pipe*. The appliances and vent manufacturers warranties
will be voided and serious fire, health, or other safety hazards
may result from any of the following actions:
- Installation of any damaged direct-vent component.
- Unauthorized modification of the direct-vent system.
- Installation of any vent component part not approved or
manufactured by the approved vent manufacturer.
- Installation other than as instructed by Lennox Hearth
Products and vent manufacturers instructions.
Residential and Mobile Home Installations:
•1 6-5/8”x 6” Black Pipe
•1 Riser Vent Terminal
• 1 Wall Penetration Heat Shield (Wall Thimble) (2 pcs)
•1 Decorative Wall Trim (black)
• 1 Tube Mill-Pac
• Screws
Optional Components:
•45º Elbow
• Vinyl Siding Shield for Riser Vent Terminal
• Vent Guard
• Snorkel Termination (36”)
• Snorkel Termination (14”)
• Wall Penetration Heat Shield
Vent Considerations:
Twist-lock procedure: Four indentations on female ends of pipes and
fittings are designed to slide straight onto male ends of adjacent pipes
and fittings by orienting the four pipe indentations so they match and
slide into the four entry slots. Push pipe sections completely together,
then twist-lock one section clockwise approximately one-quarter turn
until the two sections are fully locked. The female locking lugs will not
be visible from the outside on the pipe or fittings. They may be located
by examining the inside of the female ends.
Supports: Horizontal runs of vent must be supported every 3 feet. Wall
straps are available for this purpose.
Pipe Sealing: If Simpson Dura-Vent pipe is used, the pipe must be sealed
as follows: seal both the inner and outer pipes with a high temperature
silicone sealant rated for at least 600ºF (commonly know as “RTV”). Run
a 1/8” bead of silicone around outside of male end of outer sleeve. Run
a 1/8” bead of silicone about 1/4” from the end of the male inner pipe,
which is found in the pipe to be attached above. Twist-lock the pipes or
fittings together.
These are the minimum pieces required. Other parts may be required for
your particular installation.

1. Set the unit in the desired location. Check whether or not wall studs
are in the way when the venting system is attached. If wall studs are
in the way, you may want to adjust the location of the unit.
2. Any stove that is horizontally terminated and has a vertical section
of pipe off the top of the stove, that first section of pipe must be a
minimum of 18” long.
3. All horizontally terminated vent installations may only use 6-5/8”x 4”
Security™ Secure Vent pipe*.
4. Assemble the desired combination of pipe and elbow(s) to the appli­
ance adapter with pipe seams facing down. Offsetting the pipe seams
as double seams in one place will cause the outer pipe to take an oval
shape.
5. When this pipe passes through a wall, a wall thimble - Simpson #942
or Security™ #SV4RSM - is required. The hole in the wall for the
wall thimble should be 9-1/4”x 10-1/4”. If the wall being penetrated
is constructed of non-combustible material (i.e. masonry block or
concrete), a 7” diameter hole is acceptable and a wall thimble is not
required.
6. Horizontal runs of vent pipe must be supported every 3 feet. Wall
straps - Simpson #988 or Security™ #SV4BM - are available for this
purpose.
7. If the vent passes through a ceiling or floor, a firestop - Simpson #963
or Security™ #SV4BF - is required.
8. Also note that venting terminals shall not be recessed into a wall or
siding. If installing the termination cap on a wall covered with vinyl
siding, a vinyl siding standoff - Simpson #950 or Security™ #SV4VS
- or furring strips must be used to ensure that the termination cap is
not recessed into the siding.
9. The horizontal run of vent should have a 1/4” rise for every 12” of run
toward the termination. Never allow the vent to run downward. This
could cause high temperatures and may present the possibility of a
fire.
10.If the wall being penetrated is constructed of noncombustible material,
such as masonry block or concrete, an 7” diameter hole is acceptable
and a wall thimble is not required..
11.The location of the horizontal vent termination on an exterior wall must
meet all local and national building codes and must not be blocked
or obstructed. For allowable external vent termination locations (see
Page 17).
12.Allowable clearances from the vent pipe to combustible materials must
be maintained. See Page 9 for these clearances.
13.Do not locate the termination cap where it may be blocked by shrub­
bery or snow.
* Other approved chimney brand is Simpson Dura-Vent DV-GS.
13
Snorkel Terminations
For installations requiring a vertical rise on the exterior of the building,
14-inch and 36-inch tall snorkel terminations are available. When us­
ing a snorkel, the stove can be vented directly out the back. There is a
vent starter collar fastened to the stove (to vent straight out the back),
remove the four screws securing the collar, rotate the collar 180 degrees
and refasten using the same four screws. Make sure the gasket between
the collar and the stove is properly positioned before refastening the
collar. After rotating the collar, it will be positioned horizontally. When
this pipe passes through a wall, a wall thimble - Simpson part number
942or Security™ part number SV4RSM is required. The hole in the wall
for the wall thimble should be 9-1/4” wide by 10-1/4” high. To vent out
the rear wall, add up to a 12” section of pipe and then the snorkel. When
the stove is located in a corner of the room, to vent horizontally first
add a 45 degree elbow, then up to a 12” section of pipe and lastly the
snorkel. Installations using a snorkel have no restrictor installed in the
pipe (see Pages 15 and 16 for restrictor positioning). Follow the same
installation procedures as used for standard horizontal terminations. If
the snorkel termination must be installed below grade, (i. e. basement
application), proper drainage must be provided to prevent water from
entering the snorkel. Do not attempt to enclose the snorkel within the
wall, or any other type of enclosure. On vinyl siding, furring strips may
be used to ensure that the snorkel is not recessed into the siding.

Vertical Vent Installation
Important Notes
1.All vertically terminated vent installations use 6-5/8”x 4” Se­
curity™ Secure Vent™ pipe*.
2.If the vent passes through a ceiling or floor, a firestop - Simpson
#963 or Security™ #SV4BF - is required.
3.If the vent passes through the roof, a roof flashing - Simpson
#943 or 943S or Security™ #SV4FA or SV4FB - and storm collar
- Simpson #953 or Security™ #SV4FC - are required.
4.A 1-inch clearance from the vent pipe to combustible materials
must be maintained.
5.A maximum of either two 45º elbows or two 90º elbows may
be used. See diagrams showing allowable offsets.
6.The maximum system height is 30 feet and the minimum is 10
feet.

Flue Restrictors
4 3 2 1
The flue restrictor settings shown in Figures 26 and 27 are for typical
installations and may need to be adjusted from standard to take into
account other variables in the installation to achieve proper combustion.
See Flue Restrictor Guidelines on this page to assist you in making a
proper flue restrictor adjustment.
This appliance uses balanced flue technology to ensure proper combus­
tion. A flue restrictor may need to be installed depending on the vent
configuration of your stove. The drawings on Page 16 show all the al­
lowable pipe configurations for this appliance. To properly install the flue
restrictor, find your pipe configuration in the drawings on Page 16 and
note which restrictor setting is recommended. The flue restrictor and two
black self-tapping 5/32” allen head screws can be found in the firebox
in a plastic bag. The restrictor should be placed over the flue opening
on the ceiling of the firebox. On the restrictor, two self-tapping 5/32”
allen head screws should be installed in either holes 1, 2, 3, or 4 in the
restrictor and screwed into the two holes in the firebox ceiling. See the
drawing to the right for the location of hole numbers on the restrictor. The
numbered holes in which the screws are inserted in the restrictor should
correspond to the restrictor position numbers found on the drawings for
your pipe configuration. Restrictor positions are based on tests run in
a laboratory. The optimum restrictor positions may need to be adjusted
slightly depending on the conditions surrounding the residential instal­
lation. Do not adjust restrictors to a point where the fireplace is sooting.
Restrictor

top of the firebox
Flue Restrictor Adjustment Guidelines
A
After the flue restrictors have been set to the standard settings as shown
in Figures 26 and 27 on Page 16, the burner flame appearance should be
evaluated to determined if the flue restrictors need to be set to a different
position to adjust for variables in your installation. Light the appliance
and allow it to burn for 20 minutes. See Flame Color and Behavior on
Page 21 to determine if you have a proper burner flame appearance. If
the proper flame appearance cannot be achieved, the flue restrictor may
need to be set to a different position. See the following guidelines to
determine if you need to readjust the flue restrictors.
Figure 24
Before proceeding, confirm the manifold and inlet gas pressure is correct,
primary air shutter is properly adjusted, venting system connections are
secure and not blocked and if you are at a high elevation, ensure unit has
been properly derated:
Symptoms - Lack of Combustion Air
If the symptoms listed below are present, you may need to adjust the
flue restrictor to a more open position.
• Flame appears yellow
• Floating Flames (lazy, ill defined, quiet, may roll)
• Sooting
• Pilot becomes yellow and appliance shuts down

Horizontal Terminations
Vertical Terminations
The shaded areas in the diagram below show all allowable combinations
of vent configurations with horizontal terminations. Horizontal sections
of pipe require 1/4” of rise for every 12” of run. A second 90 degree or
45 degree elbow (in addition to the first 90 degree elbow at the top of
the vertical length of pipe) is allowed as long as the overall length of
the horizontal run of pipe does not exceed those shown below. Use the
restrictor positions indicated. Note that if the termination cap falls in the
unshaded area below then no restrictor is installed in the stove.
The diagram below shows all allowable combinations of straight verti­
cal and offset to vertical vent configurations with vertical terminations.
The termination must fall within the shaded areas on the diagram. Use
the indicated restrictor positions. Offsets may consist of two 90 degree
elbows OR four 45 degree elbows. The minimum termination height is
10’ and the maximum is 30 feet.
To install the stove with pipe directly out the back (as shown in Figure
21 on Page 14), a snorkel is required for this appliance. See Page 14 for
snorkel installation instructions.

Gas Line Installation
This stove must be connected to the gas line in accordance with local
codes and/or the National Fuel Gas Code, ANSI Z223.1 (In Canada, the
current CAN/CSA B149.1 installation code).
The gas line screws into the gas valve at the back of the stove 5” in from
the right side of the stove and 4 3/16” up from the base of the unit. After
connecting the gas line, all joints in the line and connections at the valve
should be checked for leaks. After connecting the gas line, all joints in
the line and connections at the valve should be checked for leaks before
final positioning of the unit. Conduct a gas leakage test of the appliance
piping and control system downstream of the shutoff valve in the supply
line to the appliance.
If the pressure is not sufficient, make sure the gas supply line is large
enough, The supply regulator is properly adjusted and the total gas load
for the residence does not exceed the amount supplied.
Propane tanks are at pressures that will cause damage to valve com­
ponents. Verify that the tanks have step down regulators to reduce the
pressure to safe levels.
The appliance must be isolated from the gas supply piping system
by closing its equipment shutoff 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).
The appliance and its appliance main gas valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
Gas Pressure Requirements
A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS
APPLIANCES IS IMPROPER GAS PRESSURE!
The most important item to check during the initial installation
and the first thing to check when operating problems occur is
gas pressure! This appliance will not function properly unless
the required gas pressure is supplied. See the table on this
page for gas pressure requirements.
Two pressure taps are provided on the appliance’s valve to check gas
pressures. To access the taps remove the two socket head screws to
remove the valve control panel. The taps are located above the on/off/pilot
knob (see the Figure 30 on Page 21). The right tap is the inlet (supply)
pressure side. To check inlet pressure (with the appliance burning)
insert a small flat bladed screw driver into the tap and turn a half turn
counterclockwise. Cover the tap with the line from a manometer. Read
the pressure. Close tap gently but securely after completing the check.
The manifold (outlet) tap is to the left of the inlet tap. To check manifold
pressure (with the appliance burning at the high burn setting) insert a small
flat bladed screwdriver into the tap and turn a half turn counterclockwise.
Cover the tap with the line from the manometer and check the pressure.
Again close tap gently but securely after completing the check. Check the
taps for gas leaks with a gas leak test solution (retighten if necessary).

SIT Millivolt Gas Valve
Flame Color and Behavior
This appliance is designed for maximum heating efficiency. Therefore,
upon lighting of the main burner the flames will be semi-transparent or
“bluish.” After 10-20 minutes of operation the logs will heat up and the
flames will become a yellow/orange color.
Adjusting the appliance to cause the flames to turn orange sooner may
result in poor combustion, sooting and a hazardous situation. See Figure
31 showing proper flame appearance.
When testing for proper operation - If an optional thermostat is installed
adjust it to its highest temperature setting. Visually determine that main
burner gas is burning properly: i.e., no floating, lifting or flashback.
Adjust the primary air shutter(s) as required. Check for proper main
burner operation at both high and low flame.

Air Shutter Adjustment
The air shutter control lever is located on the bottom of the stove directly
to the left of the gas valve. The lever is linked to the primary air shutter on
the main burner. The air shutter regulates the amount of primary air the
burner receives and therefore how clean the stove burns. The air shutter
should only be adjusted by a qualified gas technician. The stove should
burn for about 15 minutes with the logs installed before adjusting the air
shutter. Moving the lever down will open the shutter and turn the flames
more transparent and blue. Moving the lever up will close the shutter
and turn the flames more orange.
CAUTION: The air shutter should never be set so as to make the
tips of the flames sooty or create sooting on the viewing glass,
logs, or firebox ceiling. If soot begins to form after burning,
the air shutter should be opened gradually until the sooting
condition stops. Gas quality and gas pressure may vary which
can affect the burning characteristics of the stove.
Close
Air Shutter Control Lever
Open
If the optional blower is installed, the sound of rushing air may be heard
when the blower is on. The blower sounds may be reduced by adjusting the
speed control located on the blower assembly. Also, a slight clicking sound
may be heard as the gas valve or blower switch come on and off.
Paint Curing
This appliance has been painted with a high temperature metallic paint. It
leaves the factory dry to the touch, but completes the curing process as
the stove is used. To cure the paint, burn the appliance four successive
times for ten minutes each time with a five minute cool down between
each firing. Also some parts of the appliance may be lightly coated with
machining oil. Ventilate the house during these first firings as the paint
and oil give off carbon dioxide and unpleasant odors. It is recommended
that persons sensitive to an imbalance in the indoor air quality avoid the
appliance during the curing process.
Optional Wall Thermostat
If an optional wall thermostat is to be installed, install the thermostat per
the manufacturers instructions (provided with the thermostat). Failure
to follow manufacturers instructions could result in a malfunction. Pay
special attention to the thermostat location requirements. If the loca­
tion requirements are not adhered to the appliance, erratic operation or
failure may occur.
Do not mount the thermostat where it may be affected by:
• Radiant heat from this appliance, fireplaces, sun or other heat
sources.
• Drafts or dead spots behind doors or in corners.
• Hot or cold air from ducts.
Optional Blower
End View of Gas Valve
An optional blower (part # 75194) may be installed on your stove to
maximize heat distribution. See your Lennox Hearth Products dealer for
blower information. The optional blower is equipped with a three-prong
(grounding) plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle. Do
not cut or remove the grounding prong from this plug.
Figure 33
Quiet Operation
As the appliance is burning, a number of normal operational sounds may
be heard. The flow of gas through the gas valve and orifice may make a
rushing or whistling noise. If this noise is objectionable, it can be reduced
by turning down the flame. Turning down the flame can reduce total heat
output by more than 30%.

Operating Options
Thermostat Wire
“On-Off” Switch, Thermostat Or Remote Control
Your stove comes equipped with an “On/Off” rocker switch used to turn
the burner on and off while the pilot light is on. The switch is a round
rocker switch located behind the main control panel door.
A millivolt wall thermostat, or a remote control, can be used to supple­
ment the rocker switch. The gas valve is powered by millivolts generated
by the pilot assembly. This millivolt system is very sensitive to electrical
resistance, therefore, make sure all connections are tight, clean and free
from corrosion. Do not splice any millivolt wires. Consult the table below
to determine the proper gage of wire for the thermostat or wall switch
connections. This table refers to the total length of the wire (out to the
switch and back). The thermostat must be a millivolt type. A 24-volt
furnace thermostat will not work. Never hook up household current - 120
Volts - to the millivolt system. It is not recommended to hook up any
more than two switches to the stove (for example a rocker switch and a
wall thermostat). Additional switches may affect the system resistance
and increase the chance of the burner not igniting.
Follow the instructions included with the thermostat or remote control
for wiring. The thermostat, remote control and rocker switch will turn the
burner on and off independently. Be sure to set the rocker switch to the
“Off” position when using the thermostat or remote control and set the
thermostat or remote control to the lowest temperature when you wish
to use the rocker switch only, otherwise one may override the other.

Millivolt Control System
This stove operates on a millivolt control system. As such, no additional
power supply is needed for the stove to heat. The pilot assembly contains
a thermocouple that, when heated by the pilot flame, generates electricity
(millivolts- mV=1/1000 of a volt) which opens a valve allowing gas to
continue flowing to the pilot assembly. The pilot assembly also contains a
thermopile that, when heated by the pilot flame, generates electricity that
flows to terminal #1 (labeled TPTH) on the gas valve. When the electricity
is conducted from terminal #1 through the on/off switch, thermostat,
or receiver of the remote control to terminal #3 (labeled TH) on the gas
valve, the main burner will ignite.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation.
ATTENTION: Au moment de l'entretien des commandes,
étiquetez tous les fils avant de les débrancher. Des erreurs

Proper Pilot Flame Appearance
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
1. Annual inspection should be made and the following checks
performed:
o
When unit is cool, open glass viewing door and inspect burner for
dirt, soot and lint accumulations and remove if necessary. If exces­
sive soot accumulation is present on burner, have a qualified service
technician adjust burner for proper combustion.
o
Clean inside of glass viewing door with gas fireplace glass cleaner.
NEVER attempt to open door or clean glass when unit is hot.
o
Check the hot air outlet vents for lint or other accumulations. Never
block or restrict vent openings or obstruct flow of ventilation air.
o
Check that direct-vent pipe, air intake and flue are open and free of
soot, blockage, or debris.
o
Check gaskets once a year. Gaskets must be tight. Replace if neces­
sary.
o
Inspect the pilot system for proper flame. NEVER ADJUST THE PILOT
until after the gas pressure has been checked and supply lines have
been completely bled (this may take an hour or more when bleeding
through the pilot). All pilots are checked and burned at the factory
prior to shipment. The pilot adjustment screw is located to the lower
left of the flame height control knob.
�� Adjust the pilot screw to properly size the flames. The flames
should completely surround the thermopile and thermocouple and
extend across the main burner tube ports. Be careful not to back
the screw out of its threads.
o
Check that the area around the stove is kept clear and is free of
combustible materials, gasoline and other flammable vapors and
liquids.
o
Check the millivolt system as per the table on this page.

Figure 35
General Vent Pipe Maintenance
Conduct an inspection of the venting system semi-annually. Recommended
areas to inspect are as follows:
1. Check areas of the venting system which are exposed to the ele­
ments for corrosion. These will appear as rust spots or streaks and
in extreme cases, holes. These component should immediately be
replaced.
2. Remove the cap and shine a flashlight down the vent. Remove any
bird nests or other foreign material.
3. Check for evidence of excessive condensate, such as water droplets
forming in the inner liner and subsequently dripping out at joints.
Continuous condensate can cause corrosion of caps, pipe and fit­
tings. It may be caused by having excessive lateral runs, too many
elbows and exterior portions of the system being exposed to cold
weather.
4. Inspect joints to verify that no pipe sections or fittings have been
disturbed and consequently loosened. Also check mechanical sup­
ports such as wall straps or plumbers’ tape for rigidity.
Glass Door

CAUTION: DO NOT abuse glass door by striking or slamming shut.
Glass Door Cleaning And Maintenance
Cleaning: When cooled, the glass may be cleaned with a clean, soft
cloth and a household glass cleaner. For cleaning white condensation
from the interior glass use a gas stove glass cleaner available from your
stove dealer. Use of caustic or abrasive cleaners may damage glass. Gold
or nickel plated trim must be cleaned with a household glass cleaner or
denatured alcohol and a soft cloth before firing or fingerprints and stains
will remain permanently. Never use abrasive polish to clean the gold or
nickel as it will ruin the finish. DO NOT spray commercial glass cleaner with
ammonia on the door and glass gasket as it may dissolve the gasket glue.
Glass Replacement: Should the glass be damaged, both the glass
and the gasket should be replaced. The replacement glass and gasket
are available from your Lennox Hearth Products dealer. The glass is
neo-ceramic and alternative types must not be used. To install the new
glass and gasket: Remove the old glass and gasket. The glass is held
in place by two metal tabs located on the sides of the glass door frame.
Using a flat-bladed screwdriver or pliers, bend the tabs up to release the
old glass from the frame. Should the old glass be broken, care should be
used in removing and discarding the glass so as not to injure yourself.
Install the new glass and gasket by positioning the frame with the bent
lips up and set the glass on the frame (the glass is square so there is no
top or bottom). Slide the glass so the gasket is down against the 1/8”
lip. Using pliers, bend the metal tabs firmly down onto the gasket on the
glass. The tabs must be bent into the gasket to ensure a tight seal of the
glass to the stove. Install the glass frame on the stove. See instructions
on this page for removing and replacing the glass door. Replacement
of the glass and gasket should be done by a qualified service technician.
NOTE: BE CAREFUL NOT TO SPRAY COMMERCIAL GLASS
CLEANER WITH AMMONIA ON GASKET AREA OF DOOR. AMMONIA WILL DISSOLVE GASKET GLUE.
NOTE: GOLD PLATED SURFACE MUST BE CLEANED WITH GLASS
CLEANER AND SOFT RAG BEFORE FIRING THE FIRST TIME OR
FINGER PRINTS AND STAINS WILL REMAIN PERMANENTLY.
NEVER USE BRASS POLISH TO CLEAN GOLD, THIS WILL REMOVE GOLD PLATING!
Do not remove glass door while the appliance is hot.

Opening and Removing Glass Door
The doors on the stove may be opened to provide an unobstructed view
of the fire or to provide greater access to the firebox. To open the doors,
when the stove is cool, simply pull on the right door and it will swing
open. The left door can then also be swung open.
Lift off the stove top to access the glass door. At the top of the glass door
are two spring-loaded “I” (looped) bolts. Pull each loop forward while
rotating at 90 degrees, releasing the top of the glass door. To remove
the door, grasp it firmly with both hands and lift it up. The glass door is
fragile so it is important to place it in a secure spot until reinstalled. To
reinstall the door, the bottom of the door must be inserted in the slot at

TROUBLESHOOTING
NOTE: When troubleshooting the gas control system, be sure the external gas shut off valve, located at the gas supply inlet is in
the “ON” position.
IMPORTANT: Call your gas supplier or plumber for additional help with any gas control problem. Valve system troubleshooting
should only be accomplished by a qualified service technician.
SYMPTOM
Thin black coating
(soot) forms on the
viewing glass, logs, or
firebox.
Humming or whistling
coming from fireplace.
A change in flame
appearance or burner
operation.
PROBABLE CAUSE
Improper log or ember
placement.
See Log Set and Ember Installation.
Blocked flue.
Check for obstructions in vent pipe, check for proper restrictor setting. See Flue Restrictors.
Improper air shutter
setting.
See Air Shutter Adjustment.
Normal operating noise.
See Quiet Operation. The noise may be reduced by slightly turning the flame down. Turning
the flame down will reduce the heat output of the fireplace.
Dirt in burner orifice.
Clean orifice.
A change in gas pres­
sure.
Have your gas supplier check for correct gas pressure (7” W.C. natural gas; 11” W.C. LP
gas).
Improper ember or log
placement.
Pilot will not light.
Pilot will not stay lit
after carefully following
lighting instructions.
Main burner will not
burn.
26
CORRECTIVE ACTION
See Log Set and Ember Installation.
No gas supplied to unit.
Turn on gas.
Air in line.
To purge, hold in control knob in pilot position for 1-2 minutes and light.
Defective igniter (no
spark at electrode).
Check for spark at electrode and pilot, if no spark and electrode wire is properly connected,
replace igniter.
The valve control knob
is not turned to “pilot”
and pushed in.
See Lighting Instructions.
Pilot flame is not sur­
rounding thermocouple.
Check pilot flame adjustment (see Maintenance and Servicing section).
Thermocouple not
generating sufficient
voltage.
Check the connection between the thermocouple lead and the valve. Turn control knob to
“pilot” and push in and light pilot. While lit, take millivolt reading at lead going into valve’s
CPU. Minimum reading should be 17 millivolts. If less, replace thermocouple.
Air in gas supply line.
Purge air in pilot gas line by holding in control knob at “pilot” and sparking igniter. The air
in the line may take up to several minutes to purge.
Pilot has gone out.
See Lighting Instructions.
Rocker switch or
thermostat wires are
defective.
Disconnect rocker switch and thermostat wires at terminals 1 and 3 on valve. Jumper
across from 1 to 3 with pilot lit. If burner comes on either rocker switch or thermostat wir­
ing is not functioning.
Thermopile may not be
generating sufficient
millivolts.
Make sure thermopile is fully engulfed by the pilot flame. Check thermopile with millivolt
meter. With pilot lit and the rocker switch and thermostat off, the millivolt reading with the
meter connected to valve terminals 1 and 2 should be after 2 minutes at least 325. If the
thermopile lead connections are good at terminals 1 and 2 and readings are less than 325,
replace faulty thermopile.
