WARNING
Improper installation, adjustment, alteration, service or maintenance can cause injury or property
damage. Refer to this manual. For assistance or
additional information consult a qualified installer
or service agency.

WARNING
Do not attempt to alter or modify the construction of
the appliance or its components. Any modification
or alteration may void the warranty, certification
and listings of this unit.
1. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING
ANOTHER APPLIANCE.
2. Do not connect this appliance to air ducts or any air distribution system.
3. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING
SYSTEM OF THIS UNIT.
4. Do not use class B venting intended for gas appliances as a
chimney or connector pipe on a pellet-fired appliance.
5. The minimum clearances must be maintained for all combustible surfaces and materials including; furniture, carpet,
drapes, clothing, wood, papers, etc. Do not store combustibles
within this clearance space (see Clearances on Page 5).
6. INSTALLATION DISCLAIMER - It is imperative that the exhaust
venting system be installed correctly and sealed gas-tight
(not allowing exhaust to leak). Follow the vent manufacturer's
instructions for proper installation. Since Lennox Hearth
Products has no control over the installation of your stove,
Lennox Hearth Products grants no warranty, implied or stated
for the installation or maintenance of your stove, and assumes
no responsibility for any consequential damage(s).
7. Burning any kind of fuel consumes oxygen. If outside air is
not ducted to the appliance, ensure that there is an adequate
source of fresh air available to the room where the appliance
is installed.
8. The appliance will not operate using natural draft, nor without
a power source for the blower and fuel feeding systems.
9. Never use gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or “freshen
up” a fire in this heater. Keep all such liquids well away from
the heater while it is in use.
10. The authority having jurisdiction such as municipal building
department, fire department, fire prevention bureau, etc.
should be consulted before installation to determine the
need to obtain a permit.

11. APPROVED FUEL: This appliance is designed specifically
for use only with pelletized wood fuels only. This appliance
is designed and approved for the burning of wood residue
pellets with up to 3% ash content. This appliance is NOT
approved to burn cardboard, nut hulls, cherry pits, corn, etc.
regardless if it is in pellet form. Failure to comply with this
restriction will void all warranties and the safety listing of
the stove. Consult with your Lennox Hearth Products dealer
for more information on approved pellet fuels.
12. CONTINUOUS OPERATION: When operated correctly, this
appliance cannot be overfired. Continuous operation at a
maximum burn can, however, shorten the life of the electrical components (blowers, motors, and electronic controls),
and is not recommended. Typical approved operation would
include running at the low to mid range setting with occasional
running on the maximum setting during the coldest periods
of the winter. DO NOT OVER-FIRE THIS STOVE. Follow all
instructions regarding the proper use of this stove.
13.CAUTION: NEVER PUT FINGERS NEAR AUGER. This appliance

OR BYPASSED THIS SWITCH FOR ANY REASON. Pellet fuel is fed
to the UltraGrate™ by a screw auger. This auger is driven by
a high torque motor. The auger is capable of doing serious
harm to fingers. Keep pellets in the hopper at all times and
keep fingers away from auger. The auger can start and stop
automatically at any time while the stove is running.
14. CAUTION: HOT WHILE IN OPERATION. An appliance hot
enough to warm your home can severely burn anyone touching
it. Keep children, clothing and furniture away. Contact may
cause skin burns. Do not let children touch the appliance.
Train them to stay a safe distance from the appliance.
15. FLY ASH BUILD-UP: For all wood pellet fuel-burning heaters,
the combustion gases will contain small particles of fly-ash.
This will vary due to the ash content of the fuel being burned.
Over time, the fly-ash will collect in the exhaust venting
system and restrict the flow of the flue gases. The exhaust
venting system should be inspected regularly and cleaned
as necessary.
16. SOOT FORMATION: Incomplete combustion, such as occurs
during startup, shutdown, or incorrect operation of the room
heater will lead to some soot formation which will collect in
the exhaust venting system. A precautionary inspection on
a regular basis is advisable to determine the necessity of
cleaning. The exhaust venting system should be inspected
regularly and cleaned as necessary.
17. DISPOSAL OF ASHES: Ashes should be placed in a metal
container with a tight-fitting lid. The closed container of ashes
should be placed on a noncombustible floor or on the ground, well
away from all combustible materials, pending final disposal. If
the ashes are disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed container until
all cinders have been thoroughly cooled.
18. The instructions must be strictly adhered to. Do not use
makeshift methods or compromise in the installation.
19. Do not abuse the door glass by striking, slamming or similar
trauma. Do not operate the stove with the glass removed,

PRODUCT IS SUBJECT TO CHANGE WITHOUT NOTICE
Planning Your Installation
Questions To Ask Local Building Official

A correct installation is critical and imperative for reducing fire hazards and
perilous conditions that can arise when wood pellet burning appliances
are improperly installed. The installer must follow all of the manufacturers’ instructions.

WARNING
Check all local building and safety codes before
installation. The installation instructions and appropriate code requirements must be followed exactly
and without compromise. Alterations to the stove are
not allowed. Do not connect the stove to a chimney
system serving another stove, appliance, or any air
distribution duct. Failure to follow these instructions
will void the manufacturers warranty.
The installation of this appliance must conform to local codes and applicable state and federal requirements. Familiarity with these requirements
before installation is essential. Important considerations to discuss with
local building officials include:
1. Applicable codes (i.e. Uniform Mechanical Code, State or Regional
Codes).
Electrical codes:
In USA, NEC, ANSI/NFPA 70 – Latest Edition
In Canada, CSA C22.1 – Latest Edition

Power Supply Requirements
These requirements must be met unless otherwise specified by state or
local authorities.
• Power Cord - The power cord must be plugged into a standard, 120
Volt, 60 Hz grounded electrical outlet with proper ground and polarity.
The power cord must be routed to avoid contact with any of the hot
or sharp exterior surface areas of the stove.
• Power Supply - 575 Watts, and will peak up to 782 Watts during the
30 minute cycle when igniter is operating.
• Manufactured Home Installations - When installed into a manufactured
home, the appliance must be electrically grounded to the steel chassis
(see Page 7, Manufactured Home Requirements).

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. Do not route power cord under or in
front of appliance.
2. Local amendments
3. Is a permit required - cost. You may wish to contact your insurance
company to ask if they require this.
4. If outside combustion air is required
5. Rooms where the installation is not allowed
Surge Protectors
A surge protector is recommended to ensure the stove’s electrical components are not damaged due to a surge in the electrical supply. Only
high quality protectors should be used - cheap ones do not provide the
protection needed.

CAUTION
These appliances are very heavy. The use of a heavy
duty escalara (stair step hand truck) is recommended
for lifting the appliance.
NEGATIVE PRESSURE WARNING
This appliance is not designed to be operated in a negative pressure. Very
airtight homes with large kitchen exhaust fans, or homes with furnace
cold air returns located in close proximity to the stove may create negative pressure in the same room as the heating appliance. This can create
dangerous condition, drawing combustion by-products into the home. Be
sure your home has adequate makeup air to eliminate negative pressures
caused by the above-mentioned sources. Outside air connected to the
appliance probably will not resolve such a problem as the stove is not the
source of negative pressure. Lennox Hearth Products accepts no liability
for damages resulting from negative pressures described here.
Ventilation Requirements - Provide adequate air for combustion. The fresh
air requirements of this appliance must be met within the space where it
will be installed. Ventilation is essential when using a solid-fuel-burning
heater. In well insulated and weather tight homes, it may inhibit the rate
the exhaust flows through the venting system (caused by a shortage of
air in the home). The lack of air is caused by many common household
appliances which exhaust air from the home (such as a furnace, heat
pump, air conditioner, clothes dryer, exhaust fans, fireplaces, and other
fuel burning appliances). Also, the combustion process of this heater
uses oxygen from inside the dwelling. If the available fresh air delivery
in the dwelling is insufficient to support the demands of these appliances, problems can result (i.e. excessive negative pressure will result
in performance problems. To correct this problem it may help to open
a window (preferably on the windward side of the house) or install an
outside combustion air duct to the appliance.

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 these appliances).
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.
Installation / Maintenance Standards
National Fire Protection Association – The primary NFPA standard that
refers to installation and maintenance of pellet stoves and venting is
NFPA 211 – Latest Edition: Chimneys, Fireplaces, Vents, and Solid Fuel
appliances.

SELECTING A LOCATION
The design of your home and where you place your stove will determine
its value as a source of heat. This type of appliance depends primarily on
air circulation (convection) to disperse its heat, and therefore, a central
location is often best. There are other practical considerations, which must
be considered before a final selection of locations is made.

• Existing Chimneys
• Pellet Fuel Storage
• Aesthetic Considerations
• Roof Design (rafter locations and roof pitch)
• Room Traffic
• Proximity to Combustibles
• Electrical Wiring

FLOOR PROTECTION
This appliance requires noncombustible floor protection (the hearth pad
or alternate floor protection material does not require a thermal rating).
A noncombustible floor protector must fully cover the area beneath the
appliance and extend 6” to the front, 6” to the sides, and up to 6” from
the back as illustrated in Figure 1.
If the floor protection is to be stone, tile, brick, etc., it must be mortared
or grouted to form a continuous noncombustible surface. If a chimney
connector extends horizontally over the floor, protection must also cover
the floor under the connector and at least 2” (51 mm) to either side. See
Clearances and Hearth Protection shown in Figure 1.

VENTING REQUIREMENTS
It is recommended that only an Lennox Hearth Products dealer install your
pellet stove. The specified installation requirements must be followed to
ensure conformity with both the safety listing of the appliance and local
building codes. All clearances, installation instructions and precautions
specified by the vent manufacturer must be followed.

Silicone sealant and 3 screws are required to secure the first vent connection to the appliance flue collar. Seal the remaining vent sections per
the vent manufacturers instructions and secure all sections with 3 screws
minimum per section. ALL horizontal joints must be sealed gas-tight (air
tight, sealed connection). Use RTV high temperature silicone or Interam,
if necessary, to provide a complete seal between vent sections.

Selecting a Location

Connection to Masonry Chimney through a Wall

Review the appliance clearance requirements before installing the
venting system (see Page 5). Position the appliance far enough away
from walls to allow adequate room for servicing. Choose the appliance
location with the least amount of interference with the house framing,
plumbing, wiring, etc.

Be sure to verify the construction of a masonry chimney, as it may have
combustible framing.

Preferred Vent Configuration

Approved liner when relining Masonry or Factory-Built Fireplaces is
2100HT (degree F.) liner listed to UL 1777 or ULC S635.
Connection to an Existing Class A Chimney

For the best performance, we recommend a vent run design which runs
vertically and terminates above the roof line. This design will allow natural
draft to improve the flow of flue gases and will aid in combustion and
stove performance.

A chimney adapter can be used to make the connection from 3” (75
mm) or 4” (100 mm) pellet vent pipe (listed to UL 641 or ULC S609) to
existing UL chimney system. Verify with the pipe manufacturer that your
pipe brands will interconnect.

Note: 30 feet maximum vertical vent allowed (6 inches minimum vertical).

Horizontal Vent Installations

Type of Pipe
This stove requires type “PL” vent pipe (pellet vent pipe, sometimes
referred to as “L-Vent pellet vent”), listed to UL 641 or ULC S609. Connect the pellet vent pipe or the “tee” to the flue collar using a minimum
of three screws and seal as specified in “Pipe/Liner Joint Requirements”
on this Page. Do not use class B gas chimney or single wall chimney
as a substitute.
Size of Pipe
These pellet stoves are approved for use with the following vent sizes: 3”
(75 mm) standard, or 4” (100 mm), see Page 13 - for determining correct
size vent). When 4” pipe is used: for horizontal vent installations use a 3”
(75 mm) to 4” (100 mm) adapter - available from vent manufacturer. For
vertical installations use a 3” (75 mm) to 4” (100 mm) “tee” - available
from vent manufacturer.
Offsets
In every installation, a single or double clean-out “tee” is recommended
for every ninety-degree offset (this tee will help collect ash residue and
will allow for routine cleaning without the need to disconnect sections
of pipe).
Pipe Clearances/Requirements
See pipe manufacturers instructions for installation of venting components
and clearances. Follow pipe manufacturers installation precautions for
passing pipe through a combustible wall or ceiling (i.e. use an approved
thimble).

Pipe/Liner Joint Requirements

Notes
• Offsets and horizontal runs accumulate fly-ash and soot which reduces
the exhaust flow and performance of the stove.
• Total Offsets in venting system should not exceed 270° total in direction change.
• Maximum Vertical Vent - 30 feet (9.14 M)
• Horizontal Runs - The maximum total horizontal run must not exceed
10 feet (3.1 meters).
• Horizontal run of pipe requires 1/4” (7 mm) rise per foot.
• Pellet vent pipe requires 3” (75 mm) clearance from outside of pipe
unless otherwise specified by vent manufacturer - all diameters: 3” (75
mm) and 4” (100 mm). A support bracket must be installed every 4
feet (1.2 m) of pellet vent pipe on the exterior wall of the house unless
otherwise specified by vent manufacturer.
• It is not recommended to terminate exhaust vent on the prevailing wind
side of the house.
• It is not recommended using a termination cap with a screen (fly-ash
can collect in a screen resulting in blockage).

On all horizontal vent installations (short, horizontal runs with no vertical
pipe); care should be taken when choosing a location for terminating the
vent. It is not recommended to directly vent the exhaust on the prevailing wind side of the house. It is recommended that when an appliance
is vented directly through a wall, a minimum of 8 feet (2.5 m) of vertical
pipe should be installed to create some natural draft. This will reduce
the possibility of smoke or odor entering the dwelling during appliance
shutdown or loss of power.
Vent Termination
Do not terminate vent in an enclosed or semi-enclosed area such as:
carports, garage, attic, crawl space, under a deck, porch, narrow walkway,
closely fenced area, or any location that can build up a concentration of
fumes such as a stairwell, covered breezeway etc.
Vent surfaces can get hot enough to cause burns if touched. Adults
should supervise children when they are in the area of a hot stove.
Non-combustible shielding or guards may be required.
Termination Cap
The termination of the outside chimney of the pellet stove shall be located
in accordance with the following:
A. Higher than 3 feet (.92 m) above any forced air inlet (air conditioner,
etc.) located within 10 feet (3 m).
B. Not less than 4 feet (1.2 m) below, 4 feet (1.2 m) horizontally from or
1 foot (3.1 m) above any gravity air inlet (door, window, etc.) which
flue gases could reenter the dwelling.
C. Not less than 2 feet (.6 m) from combustible materials such as an
adjacent buildings, fences, protruding parts of the structure, roof
overhang, plants and shrubs, etc. and not less than 7 feet (2.1 m)
above grade when located adjacent to the public sidewalks (access).
The final termination of the exhaust system must be configured so that
flue gases do not jeopardize the safety of people passing by, overheat
combustible portions of nearby structures or enter the dwelling.
D. Not less than 3 feet (.92 m) below an eave (maximum overhang of 3
feet (.92 m) or any construction that projects more than 2” (51 mm)
from the plane of the wall.
E. The distance from the bottom of termination to grade is 12” (305 mm)
minimum. This is conditional upon plants and nature of grade surface: Be
careful to choose a location for the vent termination which does not expose
people or shrubs to high heat from the exhaust gases. The exhaust gases
are not hot enough to ignite grass, plants and shrubs located in the vicinity
of the termination although they should be a minimum of 3 feet (.92 m)
away. The grade surface under the termination must not be a lawn.
F. Since sparks may escape from the exhaust pipe of any stove, use
caution when positioning the vent pipe. Refer to pipe manufacturer’s
instructions when installing and terminating the exhaust. The vent pipe
should be horizontal and never run the pipe in a downward direction
(recommend a 1/4” [7 mm] rise per foot horizontal).

Chimney Height Requirements - Site Built Residential Home
The vent termination height required is - USA, 1-foot minimum; Canada
3-feet minimum above the roof penetration point as illustrated below (Ref.
USA - National Standard, NFPA 211 and Canada National Standard CSA
B365-01. Check with your local building official for additional requirements for your area.

Termination When Connected to Masonry Chimney or Existing
Class A Chimney
A flexible corrugated chimney liner has much greater resistance to the
flow of flue gases than does a rigid liner. For this reason we recommend
that a larger, 4” liner be used on vertical runs exceeding 15 feet or that
rigid venting be used . See Figure 12.
If a flexible corrugated chimney liner is used, it must be fully extended
to eliminate any sagging and to improve the exhaust flow.

Determining Size Of Pipe To Install
To determine what diameter pipe to use in an installation (3” or 4”), first
find the “equivalent pipe length” using the following guidelines, then plot
this number and the altitude on the chart (Figure 13).
Fill out the installation chart, and calculate your total equivalent pipe
length. After you have the total equivalent pipe length, use the Pipe
Selection Chart below to determine if your installation requires 3” or 4”

3. Push the stove with pipe attached towards the wall (the pipe will go
through the wall thimble). Do not position the back of the stove closer
than 2” (51 mm) from the wall (see Clearances, Page 5).

Installing Montage™ 32FS
All PL Venting Components must be listed to UL 641 or ULC S609
1. Locate the proper position for the listed type “PL” wall thimble. Avoid
cutting wall studs when installing your pipe. Use a saber saw or keyhole
saw to cut the proper diameter hole through the wall to accommodate
the wall thimble. Use extreme caution to avoid cutting into power lines
within the wall of the home. The hole size will depend on the brand
of pellet vent that you are using. Install the wall thimble in the hole.
2. ALL INTERLOCKING PIPE CONNECTIONS MUST BE SEALED GASTIGHT AND SECURED TOGETHER PER VENT MANUFACTURERS
INSTRUCTIONS.
Position the stove approximately 12” (305 mm) from the wall on the
floor pad. Push the “PL” pipe through the wall thimble. Squeeze a
bead of high temperature silicone (RTV) sealer around the end of the
machined portion of the 3” (76 mm) pipe connector on the back of
the stove. Firmly push on a section of “PL” pipe until inner pipe liner
pushes into the bead of RTV sealer.

4. Install listed type “PL” 45 degree elbow with rodent screen or cap on
outside end of pipe. The rodent screen should be no less than 1/2” (13
mm) mesh and may clog with soot and ash if left unattended during
the burn season.
5. If the installation includes a source of outside combustion air; cut a
separate hole through the wall for the fresh air tube. This tube should
be 1-5/8” (42 mm) minimum diameter, steel only. Connect outside
air pipe to air inlet on stove. This tube must be terminated with a 45
degree elbow or hood.
Notes:
• Combustion air may also be drawn from a vented crawl space under
the home.
• All joints for connector pipe are required to be fastened together per the
vent manufacturers instructions. If vented horizontally, joints must be
made gas-tight (air tight, sealed connection) in a manner as specified
on this page (see instruction #2). INSTALL VENT AT CLEARANCES
SPECIFIED BY THE VENT MANUFACTURER.
• Greater back clearance will improve the ease of serviceability of the
stove.
• The end of the exhaust pipe must extend a minimum of 12” (305 mm)
from the outside of the building.

Silicone sealant and 3 screws required on the first vent connection.
Secure and seal the remaining vent sections per vent manufacturers instructions.

This free-standing model may be connected to an existing flue or by
installing listed type “PL” vent pipe. If a liner is run all the way to the
top of the existing chimney, the existing flue should be sealed with a
steel plate. Start a vertical run with a Tee at the back of the stove. Other
options are illustrated below.

This venting configuration allows for the best stove performance. The
vertical pipe promotes natural draft and with the chimney inside the
dwelling, the flue gases stay warm, thus rising at a consistent rate.

YOU ARE OVERFIRING. Immediately press the “STOP” button on the
control board.

Pre-lighting Instructions

General Operating Considerations

During an initial start-up, or in the case where the hopper has run out of
fuel, it will be necessary to prime the auger feed system.

Proper Burn Characteristics: Your flame should be bright yellow under
normal operations. If your flame becomes reddish/orange, your stove
probably needs routine maintenance. Excessive amounts of fly-ash buildup in the UltraGrate, clinkers in the UltraGrate, or leakage of air if the
UltraGrate is not properly seated, will starve the fire for air. (See Routine
Maintenance for information on cleaning the stove). If the problem persists, review the troubleshooting section at the end of this manual.

To prime the auger feed system:
1. Fill the hopper with recommended pellet fuel and plug the stove into
the wall outlet.
2. Press the "START" button on the control board to start the fuel feed.
Next, press the "HEAT OUTPUT" button to position #5 (maximum feed
rate).
3. Look through the combustion chamber door and when you see the first
pellets dropping into the UltraGrate™, the auger is then fully primed.
It will take 10 to 15 minutes to prime the auger.
4. Once the auger is primed, press the "STOP" button to turn off the auger
(LED will go off).

Starting Your Pellet Stove
1. Make sure the auger is primed (see Pre-Lighting Instructions on this
page), then simply push the "START" button on the control board to
activate the Fastfire™ igniter.
2. While the pellets will ignite on any heat output setting, it is recommended that the "HEAT OUTPUT" button be set to position #3. Pellets
will start feeding into the UltraGrate and should begin to ignite in
approximately seven minutes. The Fastfire igniter will automatically
shut off after fifteen minutes (on hot starts igniter will shut off after
seven minutes).
3. After the pellets are burning well, press the "HEAT OUTPUT" selector
to the desired setting. Combustion air and the pellet fuel feed rate will
adjust automatically as the "HEAT OUTPUT" button is pressed. The
flame should be bright yellow in color and there should be no evidence
of soot formation at the top of the flame. Press the "BLOWER" speed
button to increase or decrease the blower speed to the desired level
4. If operating your stove with the wall thermostat, adjust the "HEAT
OUTPUT" button to the desired demand mode (#1 through #5 on the
"HEAT OUTPUT" button). Next, adjust the wall mounted thermostat
to the desired room temperature and your stove will automatically
switch between a demand mode and stand-by mode.
Notes:
Cold Start - When the "START" button is pressed when the appliance
is cold, voltage will bypass its normal circuit through the low limit
thermal switch (for 25 to 35 minutes to allow adequate time for the low
limit thermal switch to heat [140° F min.] which will close the circuit).
The combustion and convection blowers will start at maximum speed.
After approximately 10 seconds both blowers will default to settings
they were at after the last shut down was completed (indicated by
LED's #1 to #5). The Fastfire igniter will operate for approximately 15
minutes. The auger will turn continuously for a predetermined duration at the respective Heat Output Settings, followed by the normal
operating mode.

Manual and Automatic Operation
Your pellet stove can be operated in either the manual or automatic mode.
The manual mode is used when operating without a wall thermostat. The
automatic mode is used when utilizing a wall thermostat. When utilizing the
thermostat capability, the burn time can be extended dramatically depending
on thermostat setting. Note: It is normal for some ash to build up on the
inner glass surface at the lower Heat Output settings.
Manual Operation
Pressing the "START" button will initiate the start-up cycle. The auger
LED will be green to indicate the “on” status. The blower speeds and
pellet feeds are fixed during this time to provide appropriate ignition.
The Fastfire igniter system will light the pellets fed to the UltraGrate, after
about 3 minutes. After the start-up cycle, your stove will be in the run
mode. At this point the stove will operate with the heat output ("HEAT
OUTPUT" button) and blower settings ("BLOWER" button) selected. These
settings can be selected either during or after the start-up cycle. Pressing
the "STOP" button during the run mode will initiate the shut down cycle
(feeding LED will go off). The pellets will stop feeding and the blowers
will run at a fixed speed for approximately 10 minutes. At this point your
stove is safely shut down. The stove can be restarted by pressing the
"START" button during the shut down cycle.
Automatic Operation
Your stove is capable of running in an automatic mode with the use of
a wall thermostat.
For the wall thermostat to control the operation of the stove, set it to a
temperature that will put it in the demand mode (calling for heat). The
thermostat will establish either a demand mode or a stand-by mode.
The thermostat should be set for the desired room temperature. If the
room temperature drops below the level on the thermostat the stove
will automatically begin the start-up cycle, as explained in the Manual
Operation section.
Once the start-up cycle is completed the stove will operate at whatever
heat and blower setting you have selected. For best operation under
thermostat control, the medium or high settings are recommended. When
the desired room temperature is reached the stove will automatically go
into the shut down cycle. The pellet feed will stop and the blowers will
continue for a controlled time allowing safe shut down of your stove. All
lights will remain on when the thermostat is open. The "HEAT OUTPUT"
and "BLOWER" settings can be changed at any time, but only take affect
during the run mode. When the temperature in the room drops to the
level set at the thermostat, the stove will again begin the start-up cycle
and resume automatic operation in the demand mode.
Note: If the "START" button is pressed while the thermostat is in the
standby mode the stove will not restart until the thermostat closes (calling for heat).

Turning Off Your Stove
Press the "STOP" button to initiate the shut down cycle (auger LED will
be red). The pellets will stop feeding and the blowers will continue to
run on a timed cycle. The stove will shut down safely upon completion
of the shut down cycle.
Shutdown Mode - When the thermostat opens (not calling for heat),
or the auger "STOP" button is pressed (feeding LED will be off), power
to auger motor will be discontinued. The blowers will continue at the
control board setting until the low limit thermal switch cools enough
(below 120° F) to open. For safety, the blowers will continue to run
for approximately 10 minutes before the unit shuts down.

Damper Operation
The damper assembly controls the amount of combustion air that is
delivered to the firebox. With the damper adjusted all the way in, the
airflow will be at its minimum. As the damper is moved outward, more
air is delivered (see Damper Location and Adjustment on Page 9).
It will be necessary to monitor the appearance of the flame during the first
4-8 bags of pellets. If the flame is smoky red or orange with evidence of
soot at the top of the flame, the damper will need to be adjusted to deliver
more combustion air (see Damper Location and Adjustment on Page 9).
If the flame is “short” at the higher burn rates, or if the pellets are burning
up in the UltraGrate™ before new pellets are fed into the fire, the damper
may need to be adjusted to deliver less combustion air.
After the damper is adjusted, re-evaluate the appearance of the flame. It
may be necessary to continue adjusting the damper in increments until
proper combustion is achieved (the flame should become yellow and
begin to “dance”).
Once the damper has been properly set (and if the routine maintenance
is performed as needed), the damper should not require re-adjustment
unless you are changing from a premium grade pellet to a standard or
high ash pellet, in which case the damper may need to be moved outward
to help prevent the accumulation of ash in the UltraGrate.

Damper Adjustment Guideline
Lack of Combustion Air:
By opening the damper, this will increase combustion air delivery. Symptoms of insufficient combustion air include; unburned fuel, lazy smoky or
red / orange flame, excessive ash or soot, excessive buildup on glass.
Contributing factors:
• High Altitude – Lack of oxygen
• Restrictive Venting (elbows, horizontal runs, cold external chimneys,
etc.)
• Dirty / Poor Quality Fuel
• Lack of Maintenance

Note: Excessive amounts of fly-ash built-up in the UltraGrate™, clinkers
in the UltraGrate or leakage of air (if the grate is not properly seated) will
starve the fire for air. See Routine Maintenance, on Pages 21 through 24
for information on cleaning requirements.
Excessive Combustion Air:
Adjusting the damper to a more closed position will reduce the combustion
air delivery. Symptoms of excessive air include; fuel burns too quickly
(results in smoking or smoldering pellets), white to yellow flame, etc. If
the damper is open too far, the burning pellets will lift off the grate and
fly up into the air much like popping corn does.
Note: Excessive combustion air reduces efficiency.
Contributing factor:
• Venting system providing excessive draft.
Correct Combustion Air / Proper Burn Characteristics:
When the damper is correctly set, the burning pellets should move (wiggle)
around slightly and the flame should be bright yellow.

Automatic Safety Features
Power Outage:
During a power outage, the stove will shut down safely. The stove will
automatically restart when power is resumed. The solid state control
board has an internal memory that will retain heat output and blower
speed settings through voltage interruptions.
A small amount of smoke may leak from the top of the window glass,
the hopper and from the combustion air intake, if the stove is vented
horizontally with no vertical pipe. This will not persist for more than 3
to 5 minutes and will not be a safety hazard. It may set off your smoke
alarm.
Note: If the area in which you live is prone to frequent power outages, it
is recommended that a minimum of 8 feet (2-1/2 meters) of vertical vent
pipe be included in a free-standing installation to induce a natural draft
in the event of a power failure.
Overheating:
High temperature thermal switches will automatically shut down the stove
if it overheats. Allow up to 45 minutes cooling time before re-lighting. Keep
enough convection air going through stove to keep it cooling properly
(adjust convection [room air] blower speed to a higher setting), this will
ensure long life of the stove. If the overheating continues, contact your
Lennox Hearth Products dealer for more information.

FUEL
Fuel Specifications - Using the Ultragrate™ burn system, this appliance
has been designed to burn wood residue pellets only (with up to 3% ash
content). Agricultural pellets (i.e. corn, alfalfa etc.) are not permitted to be
burned in the stove. Dirty fuel will adversely affect the performance of the
stove. The pellet fuel should meet P.F.I. (Pellet Fuel Institute) standards
for standard grade or premium grade residential pellet fuel. If the pellet
fuel meets these standards, it will be printed on the bag. Any questions
regarding pellet fuel can be answered at the Pellet Fuels Institute (PFI),
www.pelletheat.org.
Pellet Feed/Pellet Size - The pellet feed system is designed to handle a
wide range of pellet sizes up to a maximum of 5/16” diameter. Different
pellets may feed at considerably different rates. You may notice a difference in the burn if you change pellet fuel sizes. The longer the pellet, the
slower it will feed and vice versa. If the stove will not stay burning at the
minimum fuel feed setting, those particular pellets may not be feeding
fast enough. If this happens, reduce the amount of combustion air by
adjusting the damper. See Page 9 before adjusting the damper.
Clinkering - Silica (or sand) in the fuel, along with other impurities, can
cause clinkering. A clinker is a hard mass of silica formed in the burning
process. Clinkering is a function of the fuel, (not the stove), but adversely
affects the performance of the stove by blocking off the air passages in
the grate. Even P.F.I. approved pellet fuel may tend to clinker. A clinker
can be removed from the UltraGrate™ and placed in the ash pan with
the use of the grate scraper/ash pan tool furnished with your stove. See
Routine Maintenance (on Pages 21 through 24) for more information
on cleaning.
Ash - The frequency of removal of the ash and maintenance performed
on the stove is directly proportional to the ash content of the fuel and the
operation duration of your pellet stove. Low ash fuel may allow longer
intervals between cleaning, however, a stove burning high ash fuel may
need to be cleaned as often as everyday.
PLEASE NOTE: Lennox Hearth Products has no control over the manufacturing of pellet fuel and will not be held responsible for poor stove
performance or any damage caused by poor quality pellet fuels.
Note: See Fuel Delivery Rate on Page 18 for burn times.

CAUTION
The use of unapproved, dirty, wet and / or high salt
content fuel will void the warranty!

Wood pellets manufactured to the pellet fuels institute (P.F.I.) certification
standard are available in two grades, Standard and Premium. The primary
difference between the two is the ash content of the pellets.
The P.F.I. specification for standard grade & premium grade residential
pellet fuel is as follows:
• CHLORIDES (Salt): Less than 300 p.p.m. to avoid stove and vent
rusting.
• BULK DENSITY: 40 lb. / Cu. Ft. minimum
• MOISTURE CONTENT: 8% maximum
• ASH CONTENT: < 3% maximum (standard grade) < 1% maximum
(premium grade)
• FINES: 0.5% maximum through a 1/8” screen
• BTU CONTENT: There are a number of variations in pellet fuels that are
not included in PFI standards. For example, BTU (heat value) content
may range from just under 8,000 to almost 9,000 BTU, depending
upon species and region of the country and other variables.

FUEL FEED RATES
Different brands of pellets will feed at varying rates due to their size
and density (length and diameter). This may require a slight adjustment
in the damper adjustment (see Page 9) or the fuel feed trim control to
compensate (see Page 18).

Tool, pull the rod up and out towards the opening of the firebox. Continue pulling until the Tube Scraper reaches the top of the firebox. Pull
the tube scraper out, then repeat 2–3 times to remove fly-ash from the
heat exchange tubes.

Front

Baffle Plate

It may be easier to clean the tubes if the heat exchanger baffle plate is
removed first (located in the firebox below exchange tubes).
Baffle Removal - The baffle plate contains two keyhole slots (see Figures 24A and 24B), which allows the two retaining screws to remain in
place while removing the baffle plate. To remove baffle, loosen the two
screws holding the baffle in place (do not fully remove). Slide the baffle
plate to the left until the screw heads clear the open end of the key hole
slots. Remove the baffle plate diagonally through door opening. The tube
scraper rod can now be pulled in a more horizontal manner, which allows
the scraper to move more freely.
Note: The baffle plate should be removed at least once a year to allow
for a thorough cleaning.

Proof of Fire Switch
This switch needs to be removed and cleaned after every 100 bags of
fuel burned.
Cleaning Procedure:
1) UNPLUG STOVE!
2) Locate the switch behind the right side panel, mounted on the combustion blower.
3) Using a flat-head screwdriver, remove the 2 screws which secures the
switch to the blower housing.
4) Using a dry cloth, wipe off any flyash build-up on the sensor portion
of the switch.
5) Reinstall switch. Ensure wires are properly connected to the switch
and the connectors are not making contact with the blower housing.
Close side panel.
Note: Failure to clean the proof of fire switch when needed may result in nuisance shut-downs because the fly-ash build-up insulates heat from reaching
the switch.

1) Open firebox door.
2) Remove Firebrick Panel (see Figure 24A):
a. Remove the two firebrick retainer brackets using a 5/32" allen
wrench (located on the left and right side of the firebrick inside
firebox). Loosen the screws (do not remove) until screw heads
can be removed through the key hole slots in the brackets.
b. With the brick retainer brackets removed, lift firebrick panel up
and out.
3) Using an approved ash vacuum (a brush can also be used), remove
the ash build-up.
4) Reinstall firebrick panel.
5) Close firebox door.

Formation and need for removal - The products of combustion will contain
small particles of flyash. The flyash will collect in the exhaust venting
system and restrict the flow of the flue gases. Incomplete combustion,
such as occurs during startup, shutdown, or incorrect operation of the
room heater will lead to some soot formation which will collect in the
exhaust venting system. The exhaust venting system should be inspected
at least once every year to determine if cleaning is necessary.

UltraGrate™ (Burn Grate)

Ash Pan

Inspect the UltraGrate periodically so that the air holes don't clog with ash
or clinkers. The UltraGrate can easily be cleaned with the grate scraper
tool, or it can be removed. It is very important to monitor the ash build
up under the UltraGrate, as too much of ash will block combustion air
from entering the grate, causing pellets to pile-up in the grate. The ash
build-up under the grate is easily dumped into the ash pan by pulling out
the ash slide weekly (see Ash Slide Plate, Figure 30).

The ash pan will have to be emptied periodically, depending on amount of
fuel consumed. The ash pan is located in the pedestal. See Figure 31.

(Recommended Frequency
of 1 day – 2 weeks)

Ash Pan

UltraGrate
The grate scraper tool fits into
this slot for easy removal

Figure 29 - Inspect UltraGrate and Clean if Necessary
Ash Slide Plate
Ash that accumulates around the grate can be “dropped” into the ash
pan as follows:
1. Open the firebox door.
2. Pull open the ash release slide plate as shown in Figure 30.
3. Using a brush, sweep the ashes from the firebox through openings
to the ash pan.
4. Close the ash slide plate, then close the firebox door.
IMPORTANT NOTE: Make sure to fully close the ash slide plate when
complete. Failure to close the ash release slide plate completely may
cause the fuel to burn poorly (due to reduced air flow through the grate),
which may then cause pellets to “pile up” in the grate. The ash slide
must be fully closed for the firebox door to close.

(Recommended Frequency
of 1 day – 2 weeks)

Sweep ashes into

Creosote Removal
When wood is burned slowly, it produces tar and other organic vapors,
which combine with expelled moisture to form creosote. The creosote
vapors condense in the relatively cool chimney flue of a slow-burning fire.
As a result, creosote residue accumulates on the flue lining.
When ignited this creosote makes an extremely hot fire. The chimney
connector and chimney should be inspected at least once every two
months during the heating season to determine if a creosote buildup
has occurred.
If creosote has accumulated it should be removed to reduce the risk of
a chimney fire.
Exhaust Passages And Vent Pipe
Inspect frequently and clean when necessary. Fly-Ash will accumulate at
all bends in the exhaust system.
Note: Large amounts of fly-ash build-up will create a lack of combustion
air. Removing the clean-out tee cap on vertical installations will allow an
inspection of the ash build-up in the clean-out tee and will help you to
decide how frequently more extensive cleaning must be performed.

Door Rope Gasket

Motor Lubrication

The condition of the rope gasket around the door and windows should be
checked periodically and replaced or repaired if necessary. The door gasket
does not need to be “tight” in all areas, since a small amount of leakage is
not hazardous or detrimental to the performance of your stove.

The blowers are permanently lubricated by the manufacturer. Do not
apply oil to any part of the blower, doing so may cause damage.
Blower Cleaning
Clean the air holes on the motors of both the exhaust and room air blowers
annually. Remove the exhaust blower from the exhaust duct and clean
out the internal fan blades as part of your fall start-up.
Rear Stove Compartment
The rear stove compartment should be cleaned periodically (a minimum
of once a year). DISCONNECT ELECTRICAL CORD PRIOR TO CLEANING
STOVE. Any household dust, pet hair or sawdust should be vacuumed
or wiped out of the rear compartment of the stove, room air blower, and
combustion blower (paying special attention to vacuuming out the intakes
of both blowers). The electrical components should be wiped clean.

Door Gasket

Glass Cleaning
DO NOT CLEAN THE GLASS WHEN THE STOVE IS HOT. To clean glass,
use a mild non-abrasive cleaner when cool. Glass cleaners that are
designed for stove glass is recommended. Creosote builds up on glass
quickly when fire is burned at lowest settings. DO NOT use abrasive
cleaners on glass. Periodically clean out the door air wash (a groove at
the bottom of the door). This air wash directs air over the glass door to
minimize soot buildup on the door.

Opening Side Panels
The hinged side panels are held closed with magnets. To open, grab the
upper portion of the side panel (at front of stove) and pull each panel

Using one small piece of 320 grit sand paper and lightly sand the blemish so that the edges are “feathered” or smooth to the touch between
the painted and bare surfaces. Do not let the sand paper gum up with
paint, as this will cause scratches on the metal surface. If there are any
scratches, use 600 grit sandpaper instead. Mask off surfaces you do
not want painted. Paint lightly over the bare surface first as this will act
as an undercoat. Then paint over a larger area in smooth even strokes
to blend.

COMPONENT DEFINITIONS
• Air Wash
A small slot in the door that allows room air to be pulled into the
firebox and pours over the inside surface of the door glass to inhibit
the build up of soot.
• Auger
A motor powered screw device that transfers the fuel from the hopper
to the feed chute to deliver pellets to the UltraGrate™.
• Auger Motor
Drives the Auger. Motor specifications are: 0.5 Amp, 1.25 RPM
(revolutions per minute).
• Blower, Room Air (Convection)
The blower function is to transfer the heat from the appliance to heat
the room air.
• Blower, Exhaust (Combustion)
It has a radial impeller to deliver more air to the UltraGrate™. It pulls
air into the UltraGrate by creating a negative pressure. This is done
by extracting the exhaust gases out of the firebox and pushing the
exhaust downstream to the flue exit.
• Thermal Switches, High Limit
There are three of these high-limit thermal switches on this model.
If a temperature reaches the high limit temperature, the reset switch
will “trip” and stop the flow of electricity to the auger motor. The
thermal switches will not reset until they have cooled below low reset
temperature).
- Auto Reset Thermal Snap Switch for Room Air Blower (L25030F, N/C*) – This switch will trip at 250° F and will automatically
reset when it reaches a temperature of 220° F. This switch is
located on the room air blower jacket and is designed to detect
an overfire condition.
- Auto Reset Thermal Snap Switch for Combustion Air Inlet
(L250-30F, N/C*) This switch will trip at 250° F and will automatically reset when it reaches a temperature of 220° F. This
switch is designed to detect reversed flow or excessive heat
in the ashpan area. This switch is located on the firebox base
behind the convection jacket, directly above the ashpan. This
switch is most easily accessed by removing the ashpan

•

- Manual Reset Thermal Snap Switch for Feed Chute (L300-145F,
N/C*) This switch will trip at 300° F and will not be resettable
until it reaches a temperature of 155° F. This switch is designed
to detect if heat from the fire is approaching a path toward the
hopper. If this switch trips it must be manually reset. To reset,
open left side access door (facing stove), locate switch on the
side of the auger tube and press the red button in the center until
it clicks into the reset position.
Thermal Switch, Low Limit (Ceramic, F140-20F, N/O*) - This "proof
of fire" switch will close at 140° F and will not open until it reaches
a temperature of 120° F. This switch is located on the combustion
blower (behind the right side panel). It is designed to shut down the
stove (auger motor and both blowers) if it does not detect the heat of
a fire at the end of the initial startup period.
Hopper Lid Switch
It is located on the left hinge area inside the hopper. It detects whether
the hopper lid is open and will turn off the auger motor if the hopper
lid is not properly closed. When opening the hopper when refueling,
do not allow the hopper lid to remain open too long or the fire may
extinguish. NEVER DISCONNECT OR BYPASS THIS SWITCH FOR
ANY REASON.
Hopper
The hopper is where the pellets are stored.
Heat Output Button
It controls power to the feed system - auger motor and combustion
blower. Use the heat output button to adjust to any of the five feed
rate settings (which controls the burn rate).
Pressure Switch
A safety device used to shut off the feed system (auger motor) if there
is too much back pressure in venting system. Some possible causes
are as follows:
• The venting system is obstructed.
• High altitude or other misc. environmental conditions affecting
exhaust flow.
• Improper venting system.
The Pressure Switch is located inside the right access door right next
to the combustion blower.
UltraGrate (Burn Grate)
This is where combustion occurs and may be referred to as the “Burn
Grate”.

any wood products, so some build-up on the glass is
normal).

A)
• There is insufficient combustion air.
• Fuel feed rate is too high.

A1) Lack of maintenance (clean UltraGrate™, clean-out ports,
exhaust flow passages, venting system, combustion blower

• Remove any clinkers or ash from the bottom of the UltraGrate
that might be obstructing the primary air holes.
• Check that the heat exchange tubes are not coated with
ash.
• Clean internal exhaust ducts.
• Check gasket seal around the door. Use a thin strip of paper,
1 in. wide. Open the door and close it on the paper strip. A
slight friction should be felt when the paper strip is pulled.
Repeat this process at various locations around the door
gasket. Replace the door gasket if necessary.
• Check for blockage in the air inlet tube or exhaust pipe. Clean
as Necessary.
• Inspect glass seal to ensure that it is in good condition and
is properly seated to the door.
A2) Fuel trim may need to be adjusted down for faster feeding
fuels.
A3) Change to a better grade of fuel if necessary. Check that
the damper has been opened enough for the amount of fuel
fed.
A4) Have your Lennox Hearth Products dealer check your
combustion blower for proper operation.
A5) The venting system design is too restrictive (call your
Lennox Hearth Products Technician to evaluate how the
