8.4 Shaking
Shaking should be done only when
there is a hot fire.
The frequency of shaking will
depend on the type of stove and the
degree of burning. Shaking should be
done at least once a day, and prefer-
ably twice a day.
Best results from shaking with
Harman grates will occur if short “chop-
py” strokes are used rather than long,
even strokes.
The amount of shaking is critical.
Too little or too much, either can result
in the extinguishing of a fire due to
blocked air flow. The proper amount
normally occurs when red coals first
start to drop through onto the bed of
ashes.
8.5 Draft Controls
The heat output of the coal is con-
trolled by the primary draft control on
bottom door. Experience will dictate the
proper settings for heat requirements.
Coal responds very slowly to
changes in the draft settings. Because
of this slow response time, over-cor-
recting is a common problem. When
changes in heat output are needed,
make only small changes in the draft
setting and wait for the temperature to
stabilize.
8.6 Ashes
Ashes should never be allowed to
accumulate in the ash pit so that they in
any way impede the flow of combustion
air to the fire. Excess ash accumulation
can cause the fire to go out and also
can cause severe damage to the grates
because of the absence of a cooling
flow of air beneath them.
Ashes should be placed in a metal
container with a tight fitting lid. The
closed container of ashes should be
placed on a noncombustible floor or on
the ground, well away from all com-
bustible materials, pending final dis-
posal. If the ashes are disposed of by
burial in soil or otherwise locally dis-
persed, they should be retained in the
closed container until all cinders have
thoroughly cooled outside the dwelling.
CAUTION! ASHES SHOULD NEVER
BE ALLOWED TO A C C U M U L AT E
ABOVE THE TOP OF THE ASH PAN.
ASHES IN CONTACT WITH THE BOT-
TOM OF THE GRATES ACT AS AN
I N S U L ATOR, INTENSIFYING T H E
HEAT ON THE GRATES, AND COULD
CAUSE THEIR WARPAGE. WITH AN
EXCESSIVE ASH BUILDUP, PRIMA-
RY COMBUSTION AIR IS RESTRICT-
ED, THUS, THE UNIT’S OUTPUT
COULD BE REDUCED.
GRATES DAMAGED IN THIS WAY
ARE EASILY RECOGNIZED BY THE
EXTREME DAMAGE CAUSED TO
THE GRATES.

Coal produces considerably more
ash than wood, so the intervals
between emptying are much shorter.
For equal heat output, coal will produce
seven to ten times more ash than
wood.
8.7 Safety
Whenever a loading door is
opened, it always should be cracked
slightly to allow oxygen to enter and
burn any combustion gases that are
present before fully opening. Failure to
do this could result in sudden ignition of
the unburned gases when the door is
opened.
A stove never should be filled with
excess coal so that the flue gas exit is
blocked or impeded in any way.
Burning coal generates carbon monox-
ide. If the flue gas exit is blocked, the
carbon monoxide can be forced out of
the stove into the room, with possible
fatal consequences.
WITH THE EXCEPTION OF THE
S TA RT- U P PERIOD, THE ASH PIT
DOOR SHOULD NEVER BE LEFT
OPEN. ALSO NOTE THAT A STOVE
SHOULD NEVER BE LEFT U N AT-
TENDED WITH THE ASH PIT DOOR
OPEN.
Serious damage to the stove can
occur from overheating.
Coal stoves should not be installed
in any chimney that has had a history of
back-drafting or flow reversal. These
conditions can cause improper draft,
resulting in carbon monoxide entering
the house rather than being drawn up
the chimney. REMEMBER! COAL
GASES ARE TOXIC!
Sulfur dioxide, sulfur trioxide and
other ions released from coal burning
may corrode stainless and masonry
chimneys, and even terra cotta chim-
ney liners and brick in nearby buildings.
Coal with high sulfur content will
destroy chimneys especially fast if soot
sits in the flue for extended lengths of
time. It is important to clean chimneys
regularly.
