one ash pan full of ashes must be removed. Failure to re-
move ashes will result in a blocked grate and the re will
not burn properly. Remember, the ash pan will be hot, so
always wear protective gloves.
Ashes should be placed in a metal container with a tight
tting lid. The closed container of ashes should be placed
on a non-combustible oor or on the ground, well away
from all combustible materials, pending nal 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.

The small tray in the side of the stoker should be removed
and emptied.
The spring handle located at the center of the unit should
be cycled in and out several times. This action cleans the
interior of the heat exchanger and causes the dust to fall
into the ashpan.

The grate “clean-out” slide should be opened and reclosed
as shown in drawings below.
In the “closed” position, be sure the “grate clean-out”
plate slide is straight across as shown.
The easiest way to handle this slide is through the ash
door with a poker inserted into the hole at the end. The
purpose of this operation is to let any ash build-up, under
the grate, fall into the ash tub.
This operation can be performed while the unit is burn-
ing. However, you should rst lower the thermostat to
lower the stove temperature and be sure you are wearing
protective gloves.
