ADJUSTING BLOWER LIMIT CONTROL SET-
TINGS.
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 (See Fig. 12). These pointers
may be adjusted through their entire range of
settings to achieve the desired warm air output
from furnace. (See Fig. 15 below)
OPERATING INSTRUCTIONS
FUEL, Model 1537G
A) 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.
B) Hardwood, 18" to 26" should be split and air
dried (seasoned) for 6 months.
LIGHTING

Set the thermostat on "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 thermostat for desired temperature.
"MEDIUM" setting is normally satisfactory.
Set higher or lower for your comfort.
ADDING FUEL
When starting a fire, add small amounts of fuel
instead of adding large quantities of fuel. This will
give more complete combustion and less build-up
of tars or soot in the chimney.
Set thermostat 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 thermostat down
.
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.

Move both pointers towards the right (counter
clockwise) - 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 air cycle.
