PRIOR
TO
INSTALLATION
Step
1:
EXHAUST-AIR
MODE
The
exhaust
air
is
discharged
upwards
through
a
duct
or
directly
through
the
outside
wall
into
the
open.
xx
Exhaust
air
should
neither
be
directed
into
a
smoke
or
exhaust
flue
that
is
currently
used
for
other
purposes,
nor
into
a
duct
that
is
used
for
ventilating
rooms
in
which
stoves
or
fireplaces
are
also
located.
Exhaust
air
may
be
discharged
in
accordance
with
official
and
statutory
regulations
only
(e.g.
national
building
regulations).
Local
authority
regulations
must
be
observed
when
discharging
air
into
smoke
or
exhaust
flues that are
not
otherwise
in
use.

When
the
hood
is
operated
in
exhaust-air
mode
simultaneously
with
a
different
burner
which
also
makes
use
of
the
same
chimney
(such
as
gas,
oil
or
coal-fired
heaters,
continuous-flow
heaters,
hot-water
boilers)
care
must
be
taken
to
ensure
that
there
is
an
adequate
supply
of
fresh
air
which
will
be
needed
by
the
burner
for
combustion.
Safe
operation
is
possible
provided
that the
underpressure
in
the
room
where
the
burner
is
installed
does
not
exceed
4
Pa
(0.04
mbar).

This
can
be
achieved
if
combustion
air
can
flow
through
non-lockable
openings,
é.g.
in
doors,
windows
and
via
the
air-intake/
exhaust-air
wall
box.
If
the
air
intake
is
inadequate,
there
is
a
risk
of
poisoning
from
combustion
gases
which
are
drawn
back
into
the
room.
A
WARNING
-
Avoid
risk
of
poisoning
—
If
the
air
intake
to
the
room
is
inadequate,
there
is
a
risk
of
poisoning
from
combustion
gases
which
can
be
drawn
back
into
the
room.
Note:
When
assessing
the
overall
requirement,
the
combined
ventilation
system
for
the
entire
household
must
be
taken
into
consideration.
This
rule
does
not
apply
to
the
use
of
cooking
appliances,
such
as
hobs
and
ovens.
If
the
exhaust
air
is
going
to
be
discharged
into
the
open,
a
telescopic
wall
box
should
be
fitted into
the
outside
wall.
