Er02:
The
error
occurs
when
the
pressure
inside
the
flue
is
above
0.3
mbar
in
respect
to
the
atmospheric
pressure
:
The
pressure
inside
the
flue
MUST
ALWAYS
BE
LOWER
than
the
atmospheric
pressure
.
To
this
respect
it
is
important
to
underline
that
the
smoke
extractor
installed
on
the
heater
has
the
function
to
extract
the
fumes
from
the
heater
and
does
not
push
them
through
the
flue.
Er01/Er02:
They
occur
when
the
detector
probes
,
that
should
normally
be
closed
,
are
now
in
an
open
modus
caused
by
a
safety
device
activated
due
to
and
event
that
has
interrupted
the
circuit
causing
the
malfunction
of
the
probe.
Er03:
This
occurs
when
the
smoke
temperature
,
due
to
malfunction
,
goes
below
the
normal
values.
EnC0:
This
occurs
when
the
smoke
extractor
,
that
is
in
operation
and
always
under
control
,
has
a
sudden
stop
during
operation
=
0
rpms
EnC1:
This
occurs
when
the
heater
shows
a
different
speed
compared
to
the
selected
speed.
It
could
well
be
that
both
errors
are
displayed
at
the
same
time,
this
is
caused
if
the
three
cables
(
i.e.:
red,
black
and
white)
conveying
the
signal
to
the
board
are
accidentally
damaged
or
simply
the
cables
could
be
deteriorated
.

LIGHTING
THE
HEATER
FOR
THE
FIRST
TIME
We
recommend
that
the
pan
is
clean
before
beginning
the
procedure
of
lighting
and
that
the
ash
tray
positioned
just
below
the
pan
is
tightly
shut.
The
heater
will
perform
in
the
best
conditions
only
when
the
combustion
chamber
is
airtight
in
order
to
prevent
irregularities
in
the
combustion
process
.
Make
sure
that
the
gasket
is
tight
and
is
unbroken
.
Air
inlet
should
be
taken
only
by
the
openings
designated
by
the
project.
In
compliance
with
regulations
BS
EN
14785
and
UNI
10412
regulating
the
installation
of
water
heating
products
and
with
regulation
UNI
10683
on
wood
‐
fired
appliances
‐
they
state
that
the
base
of
the
flue
must
have
a
depression
of
10Pa.
It
is
therefore
necessary
that
particular
attention
is
paid
to
the
fume
evacuation
flues
.
If
the
flue
is
set
low
and
made
tortuous
the
natural
draught
will
be
less.
In
this
condition
the
inlet
air
to
the
combustion
chamber
of
the
heater
will
be
less
and
this
will
compromise
the
correct
combustion
.
The
slow
smoke
outflow
can
cause
in
some
events
,
a
temperature
increase
and
a
modulation
status
of
the
heater
.
It
is
possible
to
use
different
types
of
pellets
and
the
heater
must
be
adapted
to
the
different
types.
