‐
combustion
provides
a
good
usage
of
fuel
energy
and
an
almost
complete
combustion
of
the
toxic
and
harmful
substances
from
the
smoke.
Upon
lighting
the
air
flows
through
the
UCC
and
to
the
flue
pipe
(chimney).
When
the
stove
reaches
a
certain
temperature
the
air
flow
is
diverted
and
the
still
unburned
gasses
are
lead
from
the
UCC
through
an
opening
in
the
bottom
stone
plate
to
the
LCC
.
Over
the
opening
is
a
steel
dome
placed.
Flames
are
thus
lead
through
the
opening
to
the
LCC
for
post
‐
combustion
of
the
gases.
6.2.1
Automatic
regulation
for
combustion
air
The
stove
is
equipped
with
an
independent
and
self
‐
regulating
air
damper.
Hence
there
is
no
damper
handle.
The
primary
air
is
added
to
the
primary
combustion
zone,
i.e.
the
bed
of
glowing
embers.
The
cold
air
is
only
used
in
the
lighting
stage.
Secondary
air
is
added
in
the
gas
combustion
zone,
i.e.
air
which
contributes
to
the
combustion
of
the
pyrolysis
gases
(preheated
air,
which
is
used
for
the
cleaner
glass
system
and
the
combustion).
This
is
air
sucked
through
the
damper
and
is
pre
‐
heated
through
the
side
channels
and
then
emitted
as
hot
scavenging
air
onto
the
glass.
The
hot
air
rinses
the
glass
and
keeps
it
soot
free.
A
clean
combustion
is
indicated
by
clear
yellow
flames.
The
pilot
nozzles
are
placed
in
the
back
plate
of
the
upper
combustion
chamber.
They
ensure
that
the
bed
of
glowing
embers
is
fed
with
air
and
therefore
holds
a
high
temperature.
It
provides
a
quick
start
when
re
‐
fuelling
and
reduces
the
risk
of
fire
going
out.
Important!
‐
during
kindling
/
refuelling
If
an
ash
pan
is
use,
it
must
be
placed
at
the
bottom
on
lower
combustion
chamber.
