Fuel - Lennox Bella Installation And Operation Manual

Shut Down - Normal - To turn the stove off, turn the heat control dial to
off. The blowers will continue to operate until the control board completes
the shut down cycle.
Power Outage - If the stove has a momentary electrical power loss of
less than ten seconds the stove will continue to operate normally when
power resumes. If electrical power is interrupted for more than ten sec-
onds the stove will automatically re-enter the start-up mode provided the
heat control dial is still in the "On" position. If the stove is connected to a
thermostat, the stove will enter the start-up mode when the thermostat
calls for heat.
Paint Curing - Stove components have been painted with a high tem-
perature paint. It leaves the factory dry to the touch, but completes the
curing process as the stove is used. The paint will cure during the first
few times the stove is burned. 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 stove during the curing process.
Convection Blower Operation - Your Bella™ pellet stove comes equipped
with a temperature activated convection blower that extracts heat from
the stove. After the stove warms up, a heat activated switch will turn the
blower on. The speed of the blower varies with the burn rate of the stove,
but the speed is adjustable with the convection blower speed control knob,
as well. The blower will continue to extract heat after the stove shuts off
and until it is cooled down.
Operating Sounds - As the Bella pellet stove is burning, a number of
normal operational sounds may be heard. Pellets can be heard sliding
down the auger tube and into the burn pot. Also, the motor powering the
auger can be heard as the control board calls for pellets. Occasionally
a loud noise can be heard as the auger cuts a pellet in half. When the
blowers come on, the sound of rushing air may be heard. The lower the
burn rate the slower the blower operates. Hourly, the combustion blower
will blow at a high speed to clean ash from the burn pot.
CAUTIONS
INSTALLATION AND REPAIR SHOULD ONLY BE PERFORMED
BY A QUALIFIED SERVICE TECHNICIAN. DO NOT ATTEMPT TO
SERVICE THE APPLIANCE YOURSELF.
Avoid overfiring the stove - do not hand feed pellets to the
appliance.
Never use gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or fresh up a
fire in this heater. Keep all such liquids well away from the
heater while it is in use.
For your safety, do not install or operate your Bella pellet stove
without first reading and understanding this manual. Any instal-
lation or operation of the appliance deviating from that which
is stated in this instruction manual WILL void the warranty and
may be hazardous.

Due to high temperatures, the stove should be located out of
traffic areas and away from furniture and draperies. Children
and adults should be alerted to the hazards of high surface
temperature and should stay away to avoid burns or clothing
ignition. Young children should be carefully supervised when
they are in the same room as the Bella pellet stove. Clothing or
any other flammable material should not be placed on or near
the stove. Any grill, panel, or glass removed for service MUST
be replaced prior to operating the stove.
Do not operate appliance with the glass front removed, cracked,
or broken. Replacement of the glass should be done by a quali-
fied service technician.
Lennox Hearth Products, its employees, or any of its represen-
tatives assume no responsibility for any damages caused by
an inoperable, inadequate, or unsafe condition as a result of
any improper operation, service, or installation procedures,
whether direct or indirect.
The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70 - latest edition
or the Canadian Electrical Code, CSA C.1 - latest edition.

FUEL

The use of unapproved, dirty, wet and / or high salt
content fuel will void the warranty!
This stove is designed to burn wood pellet fuel. In addition, a corn/wood
pellet mixture, with a maximum of 50 percent corn can be burned. Burning
any other fuel that is not approved for use with this appliance will void
the appliance warranty. IMPORTANT: The corn/wood mix needs to be
mixed evenly before being put in the pellet stove hopper.
Wood Pellet Specifications
This appliance has been designed to burn wood residue pellets with up
to 3% ash content. Dirty fuel will adversely affect the performance of the
stove. Any questions regarding pellet fuel can be answered at the Pellet
Fuels Institute (PFI), www.pelletheat.org.4r
Pellet fuel is made from sawdust and scrap wood from many different
species of wood. Pellets are either 1/4" or 5/16" in diameter and vary
in length. The Bella stove will burn either diameter pellets. Pellets made
from hardwoods contain more ash than those made from softwoods.
Minerals from ash and sand in the pellets form clinkers under the extreme
temperatures in the burn pot. Try burning various brands of pellets until
you find one that burns with minimum ash and clinkers. Once you find
a pellet brand that burns well, continue using this brand. High ash fuel
increases the frequency of stove cleaning. Fuel with an excessive moisture
content may jam the auger assembly.
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 burn pot. Even P.F.I. approved pellet fuel may tend to clinker. See
Routine Maintenance (on Pages 25 through 31) for more information
on cleaning.
