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

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:
Applicable codes (i.e. Uniform Mechanical Code, State or Regional
1.
Codes).
Electrical codes:
In USA, NEC, ANSI/NFPA 70 – Latest Edition
In Canada, CSA C22.1 – Latest Edition
3
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.
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
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.
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.
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

Manufactured Home Exhaust Vent Pipe Installation Guidelines
Use only “PL” pellet vent pipe listed to UL 641 and ULC S609. The pipe
should extend at least 3 feet above the part of the roof through which it
passes. The top of the pipe should be at least 2 feet above the highest
required elevation of any part of the manufactured home within 10 feet
of the pipe (see Page 12, Manufactured Home Chimney Height Require-
ments).
If the exhaust vent exits the manufactured home at a location other than
the roof, and exits at a point 7 feet or less above the ground level on which
the manufactured home is position a guard or method of enclosing the
pipe shall be provided at the point of exit for a height of up to 7 feet. The
openings, if any, in this guard shall not allow a 3/4” rod to pass through.
A 1/2” rod could pass through but should not be able to touch the pipe
when inserted through the opening a distance of 4 inches.

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.
Selecting a Location
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.
Preferred Vent Configuration
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.
Note: 30 feet maximum vertical vent allowed (6 inches minimum vertical).
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).
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 direc
tion 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).

Pipe/Liner Joint Requirements
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.
Connection to Masonry Chimney through a Wall
Be sure to verify the construction of a masonry chimney, as it may have
combustible framing.
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
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.
Horizontal Vent Installations
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).
