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 venting
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; fur-
niture, carpet, drapes, clothing, wood, papers, etc.
Do not store firewood within this clearance space.
6. INSTALLATION DISCLAIMER - This stoves exhaust
system works with negative combustion chamber
pressure and a slightly positive chimney pressure.
Therefore, it is imperative that the exhaust system
be gas tight and installed correctly. Since Lennox
Hearth Products has no control over the installa-
tion of your stove, Lennox Hearth Products grants
no warranty, implied or stated for the installation or
maintenance of your stove, and assumes no re-
sponsibility 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. Continu-
ous operation at a maximum burn can, however,
shorten the life of the electrical components (blow-
ers, 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. 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 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 fin-
gers 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
specifically for use only with pelletized wood fu-
els only. With its advanced UltraGrate technol-
ogy, 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
authorized Lennox Hearth Products dealer for
more information on approved pellet fuels.
14. FLYASH BUILD-UP: For all wood pellet fuel-
burning heaters, the combustion gases will con-
tain 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.
15. SOOT FORMATION: Incomplete combustion can
occur during startup, shutdown, or incorrect op-
eration of the room heater. This can lead to some
soot collecting 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 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, outside of
the dwelling pending final disposal. If the
ashes are disposed of by burial in soil or oth-
erwise locally dispersed, they should be re-
tained in the closed container until all cinders
have been thoroughly cooled.
