Whenever adding coal to the hopper, take the opportunity to
clean the heat exchanger surfaces. After all, the cleaner the
surface, the better the heat transfer capability.
C. General Maintenance Procedures
1. Ash Removal

Wear Leather Gloves To Prevent Skin Burns!
Open the ash removal door by lifting upward on the latch
handle, then swing the door open. Pull the ash pan out of
the firebox, using the lip on the front of the pan. Once the
ash pan is removed from the stove, you can flip the carry
handle up for convenience.
Ashes must 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 closed container until all cinders have thoroughly
cooled. Do not use the ash container for other debris
or yard waste.
Remove the hopper lid and set aside. Grasp the cleaning
scraper knob and pull it toward the back of the hopper. Push
the knob back in, toward the front of the hopper, and repeat
a few times. This motion drags a chain across each of the
heat exchange surfaces, and will knock any loose ashes
down into the ash pan.
