Removing Ashes:

Fuel quality and moisture content will dictate how often it will 

be necessary to empty the ash pan. 

disposal of  Ashes
Ashes should be placed in a steel container with a tight 

fitting lid. The closed container of ashes should be moved 

outdoors immediately and placed on a noncombustible 

floor or on the ground, well away from all combustible 

materials, pending final disposal. If ashes are disposed 

of by burial in soil or otherwise locally dispersed, they 

should be retained in the closed container until all 

cinders have thoroughly cooled. Other waste shall not 

be placed in this container.

It is recommended that the stove is cold and shut down for 

removing the ash pan.
1. Open the front door of the stove and then open the ash 

door by pulling downward on the ash lip. Remove the ash 

pan (be sure to wear protective gloves if the stove is not 

cooled down). See Fig. 33.

2. Slide the ash pan back into the stove, seating it against 

the rear of the firebox. Lift the ash lip to close the ash door 

and then close the front door of the stove.

Cleaning:

The stove should be cleaned after burning approximately 1 

ton of pellets (50 bags).  The cleaner the stove, the more 

efficient it will be.   You will burn less pellets and heat output 

will be greater. 

Note: Higher ash content pellets will require more 

frequent cleaning.

1. Shut  down  the  stove  and 

disconnect power cord

    to 

insure that all motors are stopped.

2. Clean the heat exchanger with scraper as shown in fig 34.
3. Brush or scrape the inside of the stove to remove fly ash.
4. Scrape  the  burn  pot  with  the  flat  end  of  the  scraper 

provided with the stove. Inspect the holes on the burn pot 

surface. See Fig. 35.

5. Open the burn pot clean-out. Clean fly ash from the burn 

pot and replace the cover. See Figures 39 and 40 on page 

26.

6. Remove the ash pan and dispose of ashes in an approved 

manner, according to local codes.
