Only when the coal is burned down to half its original depth it
is time to add fresh coal. When doing so, open the stove pipe
damper and turn the thermostat damper to high, which will
allow the fire to burn off any accumulated gases. Open the
feed door, and with a small rake, hoe, or hooked poker pull
the glowing coals to the front of the firebox. Try not to disturb
the fire too much. Next, add a fresh charge to the back being
careful not to seal off the top. Close the feed door, but leave the
spin damper (or thermostat) open for a few minutes until the
volatile gases have burned off. It is not necessary to shake down
the ashes each time you refuel the furnace. Experience will be
your best teacher.
BANKING THE FIRE:
For extended operation, such as overnight, the fire will need to
be banked. To do so heap coal up along the sides and back of
the firebox so that the fire gradually burns it over a longer pe
-
riod of time. The intensity of the fire will also be reduced with
-
out letting it go out. Follow the same procedure as for refueling.
If possible, avoid shaking, as a heavier layer of ash will help
reduce the intensity of the fire during this time. After loading,
let the fire establish itself for about 30 minutes. Then close your
damper and automatic control to the point where the house
does not become too cold. It is important that you begin bank
-
ing early enough before retiring or leaving that you can make
necessary adjustments after the fire is well established.
To revive a coal fire that is almost out, (1) open the ash door
and stove pipe damper and close the spin damper under the
door to get a good draft through the grate. (2) place a thin layer
of dry coal over the entire top of the fire. DO NOT POKE OR
SHAKE THE FIRE AT THIS TIME! (3) after the fresh coal has
become well ignited shake the grate (just a little), refuel.
