Unsplit logs
(A) are loaded in the firebox and ignited with kindling and
paper.
-
As the fire
grows, fresh air flows in through the air intake manifold
(B), fanning the flames in the ceramic firebox. The gas
reaches 2000º F before flowing out of the firebox and down
the flame path toward the exhaust vent (C).
-
As the
superheated air moves toward the vent, its energy passes to
a fluid flowing through an internal
heat exchanger
(D). The heat
transfer fluid reaches 180º F before circulating to an
external heat exchanger (E) mounted on the back of the
furnace (heat exchanger shown is an optional add-on to the
furnace). Here, energy produced by the furnace passes to the
home heating system.
-
Dual aquastats (F) control
the operation of the furnace. One monitors the temperature
of the heat transfer fluid and controls the damper on the
air intake manifold (B). At the desired temperature, the
damper closes, shutting off the flow of fresh air and
extinguishing the fire. When more heat is needed, the
damper opens and the furnace re-fires. Heat stored in the
refractory walls of the firebox support automatic re-firing
for up to two days. The second aquastat is wired to
the home heating system so that it continues to run for a
short time after the furnace shuts down and dissipates
residual heat from the fire.
