DO NOT BURN WET COAL
mAINTENANCE
With each hopper of coal that is burned,
approximately one ashpan full of ashes must be
removed. Failure to remove the ashes will result in a
blocked up grate and the fire will not burn properly.
Remember, the ashpan will be hot, so always wear
protective gloves.
weekly:
The small tray in the side of the stoker should be
removed and emptied.(see illustration on previous
page)
The spring handle located at the rear of the flue-
pipe 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.
Every 3 months:
The grate "clean-out" slide should be opened and
re- closed as shown in drawings at left.
In the "closed" position, be sure the "grate clean-
out" 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 fly ash
build-up, from under the grate, fall into the ashpan.
This operation can be performed while the unit
is burning. However, you should first lower the
thermostat to lower the stove temperature and be
sure you are wearing protective gloves.
This cleaning can also be performed when the unit
is cold, by lifting out the grate inserts and removing
the ash with a vacuum cleaner.
