ASH
REMOVAL
Ash
should
be
removed
from
the
firebox
every
two
or
three
days
of
full
time
heating.
Do
not
let
the
ash
build
up
in
the
firebox
because
it
will
interfere
with
proper
fire
management.
The
best
time
to
remove
ash
is
after
an
overnight
fire
when
the
wood
inbuilt
is
relatively
cool,
but
there
is
still
some
flue
system
draft
to
draw
the
ash
dust
into
the
wood
inbuilt
and
prevent
it
from
coming
into
the
room.
NOTE:
The
fan
should
be
turned
in
“OFF”
position
(2)
prior
to
ash
removal
to
avoid
ashes
to
be
pulled
towards
the
inbuilt
and
then
pushed
into
the
room.
After
ashes
have
been
removed
from
the
wood
inbuilt
and
placed
in
a
tightly
covered
metal
container,
they
should
be
taken
outside
immediately.
The
closed
container
of
ashes
should
be
placed
on
a
non
‐
combustible
floor
or
on
the
ground
well
away
from
all
combustible
materials
pending
final
disposal.
Ashes
normally
contain
some
live
charcoal
that
can
stay
hot
for
several
days.
If
the
ashes
are
disposed
of
by
burial
in
soil
or
otherwise
locally
dispersed,
they
should
be
retained
in
the
closed
container
until
all
cinders
have
thoroughly
cooled.
Other
waste
shall
not
be
placed
in
this
container.
NEVER
STORE
ASHES
INDOORS
OR
IN
A
NON
‐
METALIC
CONTAINER
OR
ON
A
WOODEN
DECK.
4.4.3
RAKING
CHARCOAL
Rekindle
the
fire
when
you
notice
that
the
room
temperature
has
fallen.
You
will
find
most
of
the
remaining
charcoal
at
the
back
of
the
firebox,
furthest
from
the
door.
Rake
these
coals
towards
the
door
before
loading.
There
are
two
reasons
for
this
raking
of
the
coals.
First,
it
concentrates
them
near
where
most
of
the
combustion
air
enters
the
firebox
and
where
they
can
ignite
the
new
load
quickly,
and
second,
the
charcoal
will
not
be
smothered
by
the
new
load
of
wood.
If
you
were
to
simply
spread
the
charcoal
out,
the
new
load
will
smoulder
for
a
long
time
before
igniting.
Remove
ash
first,
and
then
rake
charcoal
towards
the
front
of
the
firebox
before
loading
so
that
it
will
ignite
the
new
load.
