FORGE OUTDOOR COAL FURNACE • OWNER'S MANUAL
The recommended method is to develop a loading schedule that corresponds
to when there is a call for heat. This will allow the outdoor furnace to run for
an extended period of time after being loaded with new coal and allow time for
the volatiles to be burned off. It also helps to reduce the buildup of flammable
gases that can cause a flashback when the firebox door is opened or a puff back
when the outdoor furnace starts.
Loading Anthracite
NOTE: Anthracite burns best when there is a demand for heat. If extended times with a
low demand for heat are expected, it may be necessary to utilize the alternate method
of heating.
1. Using the Firebox Door Opening procedure, open the firebox door.
2. Run the ash bed maintenance rod under the ash bed to loosen it and break
up clinkers.
3. Observe the coal bed to make sure all the coals are glowing. Dark spots
in the coal bed indicate a blockage of air that needs to be cleared. Use the
rake to gently stir the area and break up the ash. Hardened areas that will
not break up are clinkers that should be removed. Use the rake to work
the clinker to the top of the coal bed and remove it with the shovel.
CAUTION
Always wear the appropriate personal protective gear when removing ash and clinkers
from the firebox.
CAUTION
Dispose of ash and clinkers in a steel container with a tight-fitting lid. The container
should be placed on a noncombustible floor or on the ground, well away from
combustible materials, pending final disposal.
CAUTION
If ash and clinkers are disposed of by burial in soil or otherwise locally dispersed, they
should be retained in the closed container until thoroughly cooled. Other waste shall
not be placed in this container.
When removing ash or clinkers, be careful not to spill any outside of the noncombustible
container.
4. Use the rake to even out the coal bed.
