the fire has started to die. This will
cause  the  reloading  process  to  be
much  longer,  and  there  is  a  good
possibility of losing the fire.

Do not shake or stir with a low fire.

Open the draft control wide or open
the  ash  cleanout  door  to  get  the
maximum draft.

Run the stove with the draft control
or ash door fully open until the fire
is reasonably hot.

Start adding small amounts of coal.
Follow  the  same  procedure  as  in
paragraphs 3 and 4 in Section 11.2

When  the  new  coal  is  thoroughly
ignited or there is a substantial bed
of hot coals, the stove may be shak-
en  thoroughly.  Be  sure  to  shake
down  all  ashes  (but  do  not  over-
shake).

After  shaking,  keep  the  bottom
draft control open until you are sure
the  fire  is  continuing  to  burn  hot,
then turn the draft control down to
the proper operating level. IF THE
ASH DOOR HAS BEEN OPENED,
BE SURE TO SHUT IT (SERIOUS
DAMAGE  CAN  RESULT  IF  THE
STOVE IS RUN FOR EXTENDED
PERIODS WITH THE ASH DOOR
OPEN).

Count  the  exact   number  of  turns
from full shut to the normal operat-
ing positions so that you can adjust
the stove to the exact level of heat
output  and  length  of  burn  you
desire.

11.5 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
preferably twice a day.

Best  results  from  shaking  with
Harman  grates  will  occur  if  short
“choppy”  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.

11.6 Draft Controls

The heat output of the coal is con-
trolled by the primary draft control
on bottom door. Experience will dic-
tate  the  proper  settings  for  heat
requirements.

Coal  responds  very  slowly  to
changes  in  the  draft  settings.
Because of this slow response time,
over-correcting  is  a  common  prob-
lem. When changes in heat output
a re  needed,  make  only  small
changes in the draft setting and wait
for the temperature to stabilize.

11.7 Secondary Air

The  two  draft  controls  on  the  top
door are used to allow secondary air
to pass over the fire when burning
coal.

This  adds  oxygen  to  the  unburned
gases  (primarily  methane  and  car-
bon monoxide) and aides in burning
them. The setting for normal burn-
ing is from 1/2 to 1 turn open from
closed position. Adjust both controls
equally.  NOTE:  THESE  SAME
CONTROLS  PROVIDE  THE  PRI-
M A RY  AIR  WHEN  BURNING
WOOD.

11.8 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
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 outside the
dwelling.

CAUTION!  ASHES  SHOULD
NEVER BE ALLOWED TO ACCU-
MULATE  ABOVE  THE  TOP  OF
THE  ASH  PAN. ASHES IN CON-
TACT  WITH  THE  BOTTOM  OF
THE GRATES ACT AS AN INSU-
L ATOR,  INTENSIFYING  THE
HEAT  ON  THE  GRATES,  AND
COULD  CAUSE  THEIR  WA R -
PAGE.  WITH  AN  EXCESSIVE
ASH  BUILDUP,  PRIMARY  COM-
BUSTION AIR IS RESTRICTED (IN
COAL  MODE);  THUS,  THE
UNIT’S  OUTPUT  COULD  BE
REDUCED!

Coal  produces  considerably  more
ash  than  wood,  so  the  intervals
between emptying are much short-
er.  For  equal  heat  output,  coal  will
produce  seven  to  ten  times  more
ash than wood.

11.9 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 pres-
ent before fully opening. Failure to
do  this  could  result  in  sudden  igni-
tion 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 monoxide. If the flue gas
exit  is  blocked,  the  carbon
monoxide  can  be  forced  out  of
the  stove  into  the  room,  with
possible  f a t a l

c o n s e q u e n c e s .

WITH THE EXCEPTION OF THE
START-UP PERIOD, AN ASH PIT
DOOR SHOULD NEVER BE LEFT
OPEN.
