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.
