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.
