When
installed
behind
a
gas
hob,
the
airbox
should
be
positioned
so
that
the
bottom
of
the
intake
is
at
a
minimum
height
of
150mm
above
the
hob
to
prevent
the
gas
flame
being
drawn
into
the
intake.
For
optimum
performance
install
higher,
as
above.
When
installed
behind
an
electric
hob,
the
airbox
should
be
installed
as
for
gas
but,
can
be
positioned
so
that
the
bottom
of
the
intake
surround
is
at
bench
level.
However
for
optimum
performance
it
should
be
installed
250
‐
300mm
above
the
bench.
The
air
box
should
be
connected
to
the
motor
using
Supertube
and
all
joints
sealed
with
duct
tape
to
prevent
air
leaks.
To
install
Supertube
the
wall
noggins
or
dwangs
will
need
to
be
checked
out
60mm
to
allow
flush
fitting
before
the
wall
lining
is
fitted.
Alternatively,
the
nogs
can
be
removed
and
the
airbox
can
be
framed
as
for
a
window
and
ducting
can
be
mounted
between
“jack”
studs.
Ducting
required
for
this
unit
is
Supertube
and
must
be
sealed
to
the
airbox
using
Parmco
duct
tape.
Ensure
that
all
joins
in
the
suction
side
of
the
Motor
are
sealed.
If
it
is
necessary
to
use
flexi
‐
duct
in
this
connection,
care
should
be
taken
not
to
damage
or
cut
the
flexi
‐
duct
inside
the
wall.
The
wall
lining
fits
in
behind
the
flange
on
the
front
of
the
air
‐
box.
Ducting
from
wall
ducting
to
the
motor
can
then
be
installed
ensuring
all
joints
are
sealed.
If
a
splash
back
is
to
be
installed,
the
Grille
&
Surround
will
need
to
be
cut
into
the
splash
back
and
the
Surround
should
be
supplied
before
the
cut
is
made.
