INSTRUCTIONS
FOR
INBUILT
WOOD
HEATERS
Although
it
is
important
to
fire
each
new
load
hot
to
prepare
for
a
clean
burn,
do
not
allow
the
fire
to
burn
at
full
intensity
for
more
than
a
few
minutes.
DO
NOT
LEAVE
THE
WOOD
INBUILT
UNATTENDED
WHILE
A
NEW
LOAD
IS
BEING
FIRED
HOT.
DO
NOT
OVERFIRE.
When
you
burn
a
new
load
of
wood
hot
to
heat
up
the
wood,
the
wood
inbuilt
and
the
flue
system,
the
result
will
be
a
surge
of
heat
from
the
wood
inbuilt.
This
heat
surge
is
welcome
when
the
room
temperature
is
a
little
lower
than
desirable,
but
not
welcome
if
the
space
is
already
warm.
Therefore,
allow
each
load
of
wood
to
burn
down
so
that
the
space
begins
to
cool
off
a
little
before
loading.
Letting
the
space
cool
before
loading
is
one
of
the
secrets
to
clean
burning
and
effective
zone
heating.
4.3.5
TURNING
DOWN
THE
AIR
SUPPLY
Once
the
firewood,
firebox
and
flue
system
are
hot,
you
can
begin
to
reduce
the
air
supply
for
a
steady
burn.
As
you
reduce
the
air
supply
to
the
fire,
two
important
things
happen.
First,
the
firing
rate
slows
down
to
spread
the
heat
energy
in
the
fuel
over
a
longer
period
of
time.
Second,
the
flow
rate
of
exhaust
through
the
wood
inbuilt
and
flue
slows
down,
which
gives
more
time
for
the
transfer
of
heat
from
the
exhaust.
You
will
notice
that
as
you
reduce
the
air
setting,
the
flames
slow
down.
This
is
your
indication
that
the
wood
inbuilt
is
burning
at
its
peak
efficiency.
If
the
flames
get
small
and
almost
disappear
when
you
turn
down
the
air,
you
have
turned
down
the
air
too
early,
or
your
firewood
is
wetter
than
it
should
be.
With
good
fuel
and
correct
air
control
use,
the
flames
should
slow
down,
but
should
stay
large
and
steady,
even
as
the
air
supply
is
reduced.
