IMPORTANT WARNINGS
CAUTION: Read this manual thoroughly before starting installation. For your safety, follow the installation, op-
eration and maintenance instructions exactly without deviation. Failure to follow these instructions may result
in a possible fire hazard and will void the warranty. If this appliance is not properly installed, a house fire may
result. Contact local building or fire officials about requirements and installation inspection in your area.
1. DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE CONNECTED TO 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 vent-
ing system of this appliance.
4. Do not use class B venting intended for gas appli-
ances 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 firewood within this clearance
space.
6. INSTALLATION DISCLAIMER - This stoves ex-
haust system works with negative combustion
chamber pressure and a slightly positive chim-
ney pressure. Therefore, it is imperative that the
exhaust system is gas tight and installed cor-
rectly. Since Lennox Hearth Products has no
control over the installation of your stove, Len-
nox 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 out-
side 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 stove 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. CONTINUOUS OPERATION: When operated cor-
rectly, this appliance cannot be overfired. Con-
tinuous operation at a maximum burn can, how-
ever, 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 set-
ting with occasional running on the maximum set-
ting during the coldest periods of the winter. The
blower speed control should be turned to high
when operating the stove on the high heat setting.
11. CAUTION: NEVER PUT FINGERS NEAR AUGER.
Pellet fuel is fed to the UltraGrate by a screw au-
ger. This auger is driven by a high torque motor.
The auger is capable of doing serious harm to fin-
gers. 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.
12. CAUTION: HOT WHILE IN OPERATION. An appli-
ance 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 unit.
13. APPROVED FUEL: This appliance is designed spe-
cifically for use only with pelletized wood fuels
only. With its advanced UltraGrate technology,
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. regard-
less 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 authorized
Lennox Hearth Products dealer for more informa-
tion on approved pellet fuels.
14. 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 sys-
tem and restrict the flow of the flue gases. The ex-
haust venting system should be inspected regu-
larly and cleaned as necessary.
15. 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.
16. DISPOSING OF ASHES: Any ashes removed from
the pellet stove must be deposited in a metal con-
tainer 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 combus-
tible materials, outside of the dwelling pending fi-
nal 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.
17. SAVE THESE INSTRUCTIONS.
