INTRODUCTION (Continued)
HOW IT WORKS
The Control Board manages the rate
of
combustion
(<.Iran
fan), fuel delivery/heat output (auger gear
motor), and heat circulation (room air fan).
Draft Fan Operation
)
The draft fan pulls air into the appliance by
extracting the exhaust out
of
the firebox. This
creates a negative pressure.
It
first enters through a
flexible hose to a plenum behind the fire chamber,
then through a tube to the back
of
the firepot and
through the bottom and sides
of
the firepot
combustor plate out into the fire area. Some air
also comes through the secondary air manifold.
During combustion the .super heated exhaust
rises
in the fire chamber.
It
is drawn out at the top
of
the
fire chamber through a penthouse box.
It
then
moves downward through a channel behind the fire
chamber. The hot combustion air is drawn out by
the draft fan
and
is then forced along through the
inner pipe
of
a double duct system and exits
through the flue at the top back
of
the stove.
Though not shown, air is also forced across the
window (at the top and bottom
of
the front door
opening) to inhibit the buildup
of
soot. An optional
exhaust plate adapter allows the stove to be fitted
to
an existing
6"
stove pipe chimney system, or 3 "
pellet vent pipe. A 4" outlet
is
standard.
