Safety Precautions

IMPORTANT:  Read this entire manual before installing
and operating this product.  Failure to do so may result
in property damage, bodily injury, or even death.
Proper installation of this furnace is crucial for safe
and efficient operation.

Install vent at clearances specified by the vent
manufacturer.

Do not connect the pellet vent to a vent serving any
other appliance or furnace.

Do not install a flue damper in the exhaust venting
system of this unit.

Use of outside air is not required for this unit.  However,
fresh air and return air make-up is required for
maximum burn characteristics and heat distribution
throughout your house.

Contact your local building officials to obtain a permit
and information on any additional installation
restrictions or inspection requirements in your area.

Do not throw this manual away.  This manual has
important operating and maintenance instructions that
you will need at a later time.  Always follow the
instructions in this manual.

This heater is designed and approved as a multi-fuel,
such as corn or wood pellets, burning furnace.  Use
only dried shelled corn with a moisture content of 11%
or less (which provides the best results). A pellet type
fuel used should have an ash content of 1% or less.  If
not, efficiency will suffer, and your warranty may be
voided.

Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to
start or ’freshen up’ a fire in this furnace.  Keep all
such liquids well away from the furnace while it is in
use.

A working smoke detector must be installed in the
same room as this product.

Do not unplug the furnace if you suspect a malfunction.
Turn the ON/OFF SWITCH to ”OFF’ and contact your
dealer.

Your furnace requires periodic maintenance and
cleaning (see ”MAINTENANCE ”). Failure to maintain
your furnace may lead to improper and/or unsafe
operation.

Disconnect the power cord before performing any
maintenance!  NOTE: Turning the ON/OFF Switch to
”OFF” does not disconnect all power to the electrical
components of the furnace.

Never try to repair or replace any part of the furnace
unless instructions for doing so are given in this
manual.  All other work should be done by a trained
technician.

Allow the furnace to cool before performing any
maintenance or cleaning.  Ashes must be disposed in
a metal container with a tight fitting lid.  The closed
container of ashes should be placed on a non-
combustible surface or on the ground, well away from
all combustible materials, pending final disposal.

The exhaust system should be checked monthly during
the burning season for any build-up of soot or creosote.

Do not touch the hot surfaces of the furnace.  Educate
all children on the dangers of a high-temperature
furnace. Young children should be supervised when
they are in the same room as the furnace.

A power surge protector is recommended.  This unit
must be plugged into a 110 - 120V, 60 Hz grounded
electrical outlet. Do not use an adapter plug or sever
the grounding plug. Do not route the electrical cord
underneath, in front of, or over the furnace.  Do not
route the cord in foot traffic areas or pinch the cord
under furniture.

The furnace will not operate during a power outage. If
a power outage does occur, check the furnace for
smoke spillage and open a window if any smoke spills
into the room.

The feed door must be closed and sealed during
operation.

Never block free airflow through the open vents of the
unit.

Keep foreign objects out of the hopper.

The moving parts of this furnace are propelled by high
torque electric motors.  Keep all body parts away from
the auger while the furnace is plugged into an electrical
outlet.  These moving parts may begin to move at any
time while the furnace is plugged in.

Do not place clothing or other flammable items on or
near this furnace.

This appliance is not intended for commercial use.
