This  Multi-Fuel  heater  needs  periodic  inspection  and  repair  for  proper  operation.  It  is 
against federal regulations to operate this Multi-Fuel heater in a manner inconsistent with 
operating instructions in this manual. 

 

The Stove is not warranted against damage caused by using poor quality fuel or other fuels 
not approved for use in this Stove, incorrect operation, improper maintenance, or incorrect 
installation. 

 

CAUTION: 

Operate this unit only with the fuel hopper lid closed. Failure to do so may result in 

emission of products of combustion from the hopper under certain conditions. Maintain hopper 
seal in good condition. The auger will be prevented from operating by a hopper lid switch. Close 
lid immediately after filling hopper with fuel.

 

 

This unit requires 120-volt AC power to operate. In the event of a power failure the unit will shut 
down. 

DO NOT ATTEMPT TO RUN THE UNIT DURING A POWER FAILURE. 

 

When burning corn, wheat or rye, care should be taken in how the venting system is installed. To 
burn  corn,  wheat  or  rye  the  moisture  content  should  be  15%  or  less.  This  can  result  in 
condensation forming in the venting system in certain installations. The chimney system should 
stay within the warm envelope of the house as much as possible. Only penetrate the exterior of 
the home where the exhaust system will terminate.  

 

REMEMBER: 

Condensation from burning Corn, Wheat, Rye or Distillers Grain is detrimental 

to the venting system. Only buy Venting Systems that are warranted with burning corn.

 

 

PREVENTING  CHIMNEY  FIRES

  -

 

Chimney  fires  can  be  prevented  by  properly  operating 

the  Ashby-MF  and  by  periodic  inspection  and  cleaning  of  the  chimney.  When  burning  these 
fuels tar and other organic vapors are produced, which combine with expelled moisture to form 
creosote.  The  creosote  vapors  condense  in  the  relatively  cool  chimney  flue  associated  with  a 
slow burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this 
creosote can result in an extremely hot chimney fire.

 

 

The chimney and chimney connector should be inspected at least once every two months during 
the  heating  season  to  determine  if  a  creosote  build-up  has  occurred.  If  a  significant  layer  of 
creosote has accumulated (3 mm or more) it should be removed to reduce the risk of a chimney 
fire.  Use  of  an  appropriately  sized  chimney  brush  or  the  services  of  a  professional  chimney 
sweep are recommended.

 

 

The chimney and chimney connector should be inspected at least once every two months during 
the heating season to prevent the system  from  getting plugged with Fly  ash. Clean the exhaust 
system if needed. Use of an appropriately sized chimney brush or the Services of a Professional 
chimney sweep are recommended. 

 

ASHBY-MF APPROVED FUELS 

 

SHELLED  CORN  - 

Shelled  corn  must  be  15%  or  less  moisture  content.  The  keys  to 

satisfactory  performance  are:  proper  operation  of  the  stove,  diligent  maintenance  and  burning 
only dry, clean, quality corn. Corn dust must be screened prior to using.
