CAUTION
GASES THAT ARE DRIVEN BY FRESH COAL MUST BE
BURNED OR THEY WILL ACCUMULATE AND EXPLODE.
NEVER SMOTHER A FIRE WHEN ADDING FRESH COAL.
CAUTION
DO NOT OPERATE WITH THE FEED AND/OR ASH DOOR
OPEN. THIS FURNACE IS DESIGNED FOR THERMO-
STATIC OPERATION. OPERATION WITH ANY OF THESE
DOORS OPEN WILL OVERHEAT AND DAMAGE THE
FURNACE.
CAUTION
NEVER USE GASOLINE, GASOLINE-TYPE LANTERN
FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR
FLAMMABLE LIQUIDS TO START OR "FRESHEN UP" A
FIRE IN THE FURNACE.
CAUTION
NEVER STORE FLAMMABLE LIQUIDS, ESPECIALLY
GASOLINE, IN THE VICINITY OF THE FURNACE.
OPERATING INSTRUCTIONS
The temperature in the plenum of the warm air furnace at
which the blower turns on or turns off is controlled by the
setting of the pointers in the blower limit control. These
pointers may be adjusted through their entire range of
settings to achieve the desired warm air output from the
furnace. (See Fig. 15)
1.

3.
Move both pointers towards the right (counter clock-
wise) - this increases the temperature setting at which
the blower will turn on and off.
Move both pointers towards the left (clockwise) - this
decreases the temperature setting at which the blower
will turn on and off.
Move pointers away or apart from each other- this
increases the time that the blower will run on each
warm cycle.

COAL FUEL
Egg size (1-3/16" or larger) bituminous coal for residential
furnaces, or any of the specially packed fireplace coals can be
used. Coal with a low ash content (2% to 6%) is recommended.
WOOD FUEL
Hardwood, 18" to 26" should be split and air dried (seasoned) for
6 months.
LIGHTING

4.
Open the draft controls to "HIGH" for maximum draft.
Open the feed door and place paper and kindling on the grate
for starting the fire.
Light the fire and close the feed door.
Add wood or about 15 lbs. of coal (depending on which
model) after fire is burning briskly.
Set draft control for desired temperature.
ADDING FUEL
When starting a fire, add small amounts of fuel instead of adding
large quantities of fuel. This will give more complete combus-
tion and less build-up of tars or soot in the chimney.
Set draft control to HIGH before opening feed door.
Wood fire
Add wood to a convenient level.
Coal Fire
Never smother the fire when adding coal (See Caution).
Gas accumulation and a mild smoky explosion will occur.
Add fresh kindling if the bed of coals has cooled.
Add up to 20 lbs. of coal per loading. Never add coal above
the bottom of feed door opening.
Stir the coal and watch the fire. Be sure the new coal is
burning briskly before you close the doors and turn the lower
the drat control setting down. 1.

Shake grates vigorously 1/2" left to right to spill
ashes into the ash pan. Do this at least once every
12 hours of operation. Empty ash pan regularly.
Do not allow ashes to build-up to grate as grate will
warp and burnout, and you might spill the ashes
when removing the pan.
Dispose of hot ashes properly (See note 12 on
page 4).
Rotation of the handle (5 o'clock to 7 o'clock)
position will agitate coals and spill ashes into ash
pan.
It is advisable for you to get familiar with the shaker
grate operation before firing. d.
