Operation
BURN AIR-DRIED WOOD, OR ANTHRACITE OR BITUMINOUS COAL ONLY
All home chimneys and hookups are different. After a few fires, you will find the best way to start a
fire in your ENERGY KING Wood/Coal Boiler.
You will get the best efficiency when you add only the amount of coal needed for a 6 to 8 hour burn.
A full load is not always the best solution for your needs.
Burning Coal
Burning coal will provide a lesson in patience.
Take the time necessary to experiment and
understand the operation of your ENERGY
KING Wood/Coal Boiler.
Please keep the following points in mind
when burning coal:
1. A Barometric draft control in the chimney
connector
must
be used when burning
coal.
2.
Never
completely cover the live fire with
fresh coal. Always leave a generous area
of burning coal at the top and rear of the
fire.
3. Always keep the ash pan clean. Coal firing
produces much more ash than wood.
These ashes must be removed often
(possible daily) in order to avoid piling up
too closely to the grates.
Removal of the coal ash will allow for
passage of primary air to the coal bed and
prevent damage or warpage to the grates.
4. A coal fire should not be poked or broken
up, as this tends to bring ash to the surface
of the coal bed where it may fuse. If the
ash fuses, clinkers will form. It may be
necessary to remove all unburned material
and ash from the burn chamber to remove
the clinkers. These should be carefully
removed using tongs, and always put into
an airtight metal container.
5. If the fire goes out or does not hold
overnight, check for the following:
a. Poor Draft
b. Incorrect damper settings.
c. Improper firing methods for the coal
being used.
d. Coal is not sized to the boiler (see
Fuel
Requirements – Coal).
e. Ashes, if allowed to accumulate in the
ash pan, will not allow the passage of
required air for combustion. Keep the
ash pan clean.
Dispose of ashes with care:
Ashes should be placed in a metal
container with a tight fitting metal lid.
The closed container of ashes should
be placed on a noncombustible floor
or on the ground, well away from all
combustible materials, pending final
disposal.
All coal contains small amounts of
dangerous elements. Therefore it is
essential that your coal ash be
disposed of in municipally designated
areas.
