burning coal on 1/-inch oPening grates
(Optional)
general inforMation
This information contains the instructions for burning various types
of coal, storage of coal, and the cleaning of the furnace.
Some coal is oil-treated at the mine and some users have indi-
cated that it tends to make the coal more difficult to start.
Burning coal requires some patience and a regular procedure.
With improper tending, a coal fire can go out in a short time. Once
the fire starts to go out, it is almost impossible to reverse. After a
coal fire goes out, all the coal must be removed from the furnace
before the starting process can be repeated.
Our coal burning instructions are general, as coal comes in various
sizes and types. Anthracite coal is most recommended as it burns
with little smoke when burning properly.

ignition teMPerature of coal and Wood
How hot does coal have to get to ignite? Following are examples
of the ignition points of various materials:
Paper ignites @ 350º F
Wood ignites @ 435º F
coal:
Western lignite ignites @ 630º F
Low volatile bituminous ignites @ 765º F
High volatile bituminous ignites @ 870º F
Anthracite ignites @ 925º F
What siZe coal should i burn?
The air space between the furnace grates is 1/2 inch; therefore,
coal smaller than 1/2 inch can fall through the grates into the ash
pan.
Pea size coal ranges from 9/16 to 11/16 inches.
Nut size coal ranges from 1-3/16 to 1-5/8 inches.
Stove size coal ranges from 1-5/8 to 2- 7/16 inches.
Nut size is preferred by most people and is recommended for use
in this furnace.
Anthracite coal is hard and burns like the charcoal that is used
in your barbecue grill. The coals must touch each other to ignite.
Therefore, the smaller the coal, the easier to ignite. Stove coal is
not as likely to touch each other because of its size.
Bituminous coal is soft and not as desirable as hard coal. It creates
dust when handled and produces large amounts of smoke and
soot when burned at a slow rate. Also, soft coal from some areas
of the country contains higher sulfur content, but a large portion of
it may be removed if the coal is cleaned .
hoW to start a coal fire
caution
Do not use kerosene, gasoline, thinners, etc. to start a coal fire.
To start a coal fire, place a small amount of crumpled paper and
sticks of kindling wood on the ash-covered grates.
Ignite the paper and after the wood is burning briskly, cover with
a thin layer of coal. As the first layer of coal becomes ignited, add
more coal gradually until the fire bed is built up to approximately
6 inches deep. As fresh coal is added always leave some of the
glowing coal uncovered.
Draw the top red coals toward the front of the firebox and pile fresh
coals toward the back.
The grates must be protected from direct contact with the fire by
a layer of ash, one (1) or two (2) inches thick. The ash left on the
grate will help prevent overheating of the cast iron grates and coal
from falling through the grate's opening.
Maintaining a coal fire
Bituminous coal should be built into a cone shape once the fire
has started. When refiring, break up the cone a little using a poker,
especially if it has caked over to form a crust. Be careful not to mix
the coal as this increases the chance of forming clinkers.
Western lignite coal should be burned the same way you would
burn wood. (Refer to wood burning instruction.)
