PLANNING DUCTWORK
INSTALLATION
(This
section
for
F30WV
hoods
only.
F30WR
and
F24WR
hoods
skip
this
section
and go on to "Prepare
the Hood'.')
Begin
planning
ductwork
by deciding
where
the duct
will run
between
the range hood and the outside.
For best performance,
use the shortest
possible
duct
run and a minimum
number
of
elbows.
There
are several
choices
shown
- FIGS.
A - F below.
FIG.
A. Ducting
directly
through
the wall
(for
range
hoods
mounted
on an exterior
wall).
Shown
are two ways
to duct
through
an outside
wall.
If a wall
cap is used
directly
off the
back of the hood,
special
care must be taken
to make
sure that
the damper
in the damper/duct
connector
on the hood
and
damper
in the wall
cap do not interfere
with
each
other
when
the hood is operating.
This could
result in either
inadequate
air
delivery
or backdrafts.
If this condition
does
exist,
remove
the
hood
damper
flap. Sometimes
when using a wall cap it is easier
to duct vertically
and then
use an elbow
as shown
in FIG. B.
In more
complex
ducting
situations,
a 3-1/4"
x 10"
rec-
tangular
ducting
range
hood
(F30WV
hood)
can be converted
to a round duct
by means
of a transition.
FIG.
C.
Ducting
straight
up
through
the
roof
using
3-1/4"
x 10" rectangular
duct
(for single
story
installations
-
F30WV
hood
only).
FIG. D. Ducting
between
the ceiling joists
(for multi-story
instal-
lations)
or through
the soffit space
above
the cabinets
(where
the soffit connects
to an outside
wall).
FIG.
E. Straight
up through
the roof
using
6" round
duct
(for
single-story
installations).
