Spring Shutdown.

 After the last burn in spring let the unit cool down. Remove all fuel from 

the Hopper and the Auger. Thoroughly clean the Burn Pot, Burn Pot box, Ash Pan and Ash 
Traps behind the ash pan. (To locate the ash traps see figure 28 on page 41) 

 

2.  The Exhaust System should be thoroughly cleaned at least annually. Call your dealer for this 

service. (See figure 29 on page 42)

 

 

3.

 

The Motor/Fan area behind the firebox and under the hopper should be vacuumed annually. 
(See figure 29 on page 42) 

 

4.

 

The  exhaust  fan  should  be  removed  and  cleaned  with  compressed  air  annually.  Call  dealer 
for this service. Annual oiling of the motors is not needed. (See figure 29 on page 42) 

 

5.

 

The Convection fans should be removed and cleaned with compressed air annually. Annual 
oiling of the motors is not needed. (See figure 29 on page 42)   

 

6.

 

Replace the Door Gaskets if needed. 

 

7.

 

Replace the Ash Pan Door gaskets if needed. 

 

8.

 

Replace the Hopper Lid Gaskets if needed. 

 
 

SAFE OPERATION. 

 

Fall  Startup. 

Prior  to  lighting  the  first  fire  check  the  outside  area  around  the  exhaust  and  air 

intake systems for obstructions. Try all controls to see that they are working prior to lighting a 
fire. 

 

1.

 

Disposal of Ashes. 

Ashes should be placed in a metal container with a tight fitting lid. The 

closed  container  of  ashes  should  be  placed  on  a  non-combustible  floor  or  on  the  ground,  well 
away  from  all  combustible  materials,  pending  final  disposal.  If  the  ashes  are  disposed  of  by 
burial  in  soil  or  otherwise  locally  dispersed,  they  should  be  retained  in  the  container  until  all 
cinders have thoroughly cooled. 

 

2.

 

Never use Gasoline, 

gasoline type lantern fluid. 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. 

 

3.

 

Creosote, Soot and Fly Ash: 

Formation and Need for Removal. The products of combustion 

will contain small particles of Fly Ash. The fly ash will collect in the venting system and restrict 
the flow of flue gases. Incomplete combustion, such as occurs during start-up and shut-down, or 
incorrect  operation  of  the  room  heater  will  lead  to  some  soot  or  creosote  formation  which  will 
collect  in  the  venting  system.  The  exhaust  system  should  be  inspected  regularly  during  the 
heating season to determine if creosote buildup has occurred. Check more frequently  at first to 
determine  a  schedule  for  cleaning  the  venting  system  based  on  individual  use  of  this  Stove.  If 
creosote has accumulated, it should be removed to reduce the risk of a chimney fire. 

 

4.  

Do  not  Overfire  this  unit  by  tampering  with  the  controls  on  the  unit. 

Follow  all 

instructions regarding the proper use of this heater.
