OPERATION
Burning Coal
Your furnace is capable of burning both Bituminous and
Anthracite coal. Anthracite is perhaps the best coal fuel
because its long even burn time, high heat output, and
cleanliness make it a good choice for the home. However,
keep in mind it is a much more dif
fi
cult fuel to use, requires
more care and patience, is not so widely available, and is
usually much more expensive than bituminous.
Size Of Coal
Most sizes of Bituminous Coal will work in your New
Furnace, for best results we recommend large nut coal
to small egg coal (1-3/4” dia. to 4” dia.). When burning
Anthracite, use egg or broken with sizes between 2-5/16”
thru 4-3/8”. Note that it is important to the long life of your
furnace to buy coal which has been sized and cleaned.
Cleaning insures removal of rocks and other materials.
Never use coal smaller than 1” or larger than 5” in diam-
eter. Small sized coal will smother the
fi
re. Too large a
size of coal will not burn well.
Stove Operation
All coal
fi
res should be started with wood which will allow
the
fi
re to get hot enough to ignite the coal. The best
ignition
fi
res utilize dry pine or other resinous soft woods
as kindling, with hard wood (oak, hickory, ash) added to
increase the heat prior to addition of the coal.
Burning Bituminous
Once your kindling and wood
fi
re has produced a bed of
well established coals, start adding coal in layers allow-
ing each to ignite before adding more. Bituminous has
a high volatile content and, as a result, should be
fi
red
with the “conical method” - with the highest portion of your
fi
rebed in the center of the
fi
rebox. The
fi
rst
fl
ames will be
long and generally orange or yellow and produce quite a
bit of smoke. As the gases burn off the
fl
ames become
shorter, change colorand produce less smoke. Once the
fi
re is WELL ESTABLISHED add coal to the center of the
fi
rebox forming the cone. Burning in this fashion allows
heat to drive off the volatile gases, and turbulence created
increases the burn ef
fi
ciency. You will have to experiment
with your particular setup as no two chimney’s or installa-
tions are going to be the same. Just remember to allow
enough secondary air to enter the
fi
rebox and keep your
stove pipe damper open so that volatiles are properly
burned. Before refueling, take the time to break up the
cone a little with a poker, especially if it has caked over or
formed a crust. But, be careful not to mix the coal as this
increases the chances of forming clinkers. When shaking
the grate(s) be gentle. Just a few short movements is
better than a lot of agitation. The objective is to remove
a small amount of the ashes without disturbing the
fi
re.
Stop when you see a glow in the ashes or the
fi
rst red
coals fall into the ash pan. Excessive shaking wastes fuel
and can expose the grate(s) to very high temperatures
which can cause warpage or burnout.
For overnight operation (long duration burn time) shake
the
fi
re and add coal, retaining your center cone. Once
the volatiles are burned off, close the feed door and adjust
your stove pipe damper. Then adjust your thermostat to
the desired heat level.
You will have more MAINTENANCE with bituminous than
with anthracite coal as more soot will collect on heating
surfaces and in pipes, requiring more frequent cleaning.
Anthracite
Before starting the
fi
re open - the stove pipe damper, open
the ash pit door and feed door, place newspaper,
fi
nely
split kindling on the grate, and light the paper. Add larger
hard wood after kindling is burning brightly.
CAUTION:
Never use gasoline, lantern fuel, kerosene, charcoal
lighter
fl
uid, or other
fl
ammable liquids to start or
freshen up a
fi
re in this heater.
Place the larger pieces
of wood on the
fi
re so that they are slightly separated and
form a level for the addition of coal. It will take 10 to 20
minutes before this wood is thoroughly ignited. Adding
coal too soon will cut the air supply and smother the
fi
re.
Add a thin layer of coal (preferably smaller chunks) to the
wood
fi
re, being careful not to disturb it too much or cut
off the draft. Then, add a second heavier layer after the
coal is ignited and burning well. If necessary, add a third
layer to bring the coal up to the top of the front liner (not
above!). Be sure you have closed your ash door.
Before adding further fuel, be sure you leave a red spot of
glowing coals in the center of the
fi
rebox to insure that you
have not smothered the
fi
re and to help ignite thegases
given off by the new charge. A deep charge will give a
more even heat and a longer
fi
re, but it may take one to
two hours before the whole bed is fully ignited.
When the
fi
re is well established and the room is becom-
ing warm, partially close the dampers. You will have to
experiment with your particular setting of the damper and
controls as your chimney provides the draft necessary to
not only exhaust the smoke, but to pull combustion air
into the heater as well - and no two chimney’s perform the
same. Leave the ash pit damper at least partially open
to prevent the
fi
re from going out. Adjust the stove pipe
damper to reduce the draft on the
fi
re. With anthracite you
will see short blue
fl
ames above the coal, except when
the
fi
re is started or a new charge is added. If, however,
there is no
fl
ame then the
fi
re needs more air from the
bottom (unless it is near the end of its burn cycle and
needs to be recharged).
Only when the coal is burned down to half its original
depth is it time to add fresh coal. When doing so, open
your stove pipe damper, which will allow the
fi
re to burn
off any accumulated gases. Open the feed door, and with
a small rake, hoe or hooked poker pull the glowing coals
