Ash Removal

With each hopper of coal that is burned, approximately one ash pan full of ashes must be removed. Failure to re- move ashes will result in a blocked grate and the fire 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 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.

Weekly:

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.

Every 3 months:

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.

Baffle slideThe 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 first lower the thermostat to lower the stove temperature and be sure you are wearing protective gloves.
