THE
FLUE
SYSTEM
8.1
GENERAL
The
flue
system
,
made
up
of
the
external
flue
system
and
the
internal
flue
is
the
important
draft
system
that
drives
your
wood
heating
appliance.
Even
the
best
wood
fire
will
not
function
safely
and
efficiently
as
intended
if
it
is
not
connected
to
a
suitable
flue
system.
The
heat
in
the
flue
gases
that
pass
from
the
wood
fire
and
flue
into
the
flue
system
is
not
waste
heat.
This
heat
is
what
the
flue
system
uses
to
make
the
draft
that
draws
in
combustion
air,
keeps
smoke
inside
the
wood
fire
and
safely
vents
exhaust
to
outside.
You
can
think
of
heat
in
the
flue
gas
as
the
fuel
the
flue
system
uses
to
make
draft.
