Section 2 - Operating Instructions
Radiant heat from glowing ember bed dries
and cleans air channels, and
also will ignite new wood load
Before reloading, use the
cleaning rod to loosen the ash and coals
as directed in the Owner’s Manual

It is best to burn the wood
load down to a glowing coal
bed as often as possible
to dry the firebox,
air channels and ashes.
These illustrations provide a summary of how to properly load and reload your downdraft outdoor furnace. Be sure to read the Owner’s Manual for other important safety
and operational information. Over time, you will become familiar with your particular conditions, and you will learn how best to load the wood so it burns down to a
glowing coal bed as often as possible before reloading. ©2015 Central Boiler • 1-MAY-2015
Low humidity
A dry firebox lasts
longer, requires less
maintenance and
operates with more
efficiency than a
wet firebox.
A firebox with high humidity requires more maintenance, operates with less efficiency and will shorten the life of the furnace.
Loading more wood than is needed between
fills increases condensation – the firebox
and air channels will not dry
NO DRYING
Very little radiant heat
to dry air channels
High humidity
Reloading at this level can restrict airflow and
create excessive coals or too deep of a coal bed,
while making it impossible to run the cleaning
rod through to loosen the ash and coals
Repeating this type of reloading pattern, along with
not following other procedures described in the
Owner’s Manual and instructional videos,
will diminish the efficiency, performance and life
of the furnace
Adding more wood than is needed between loads increases condensation and reduces efficiency.
Coal bed is too deep
to allow enough air
to keep the bottom of
bed glowing, which
is needed for
proper operation.
Coal bed will continue to
deepen and
operating efficiency
will continue to diminish
Here, wood is added before
remaining wood is allowed
to burn down.
DRYING
Radiant heat dries
and cleans air channels
High humidity
Load enough wood to maintain the fire until next reloading,
preferably about 12 hours

High humidity
OR
Operating for a 12-Hour Burn
Run the rod through
the coal bed in a
number of places once
every 8-12 hours to
avoid bridging and
to help optimize
combustion.
Wood between 4" and 8" (10-20 cm)
across and approximately
60-70% of the length of the
firebox works well in most cases.
