PLANNING DUCTWORK
INSTALLATION
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.
1A-
1E.
In more complex
ducting
situations,
a 3-1/4"
rectangular
ducting
range
hood
can be converted
to a round
duct
by means
of a
transition.
FIG.
IA.
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 oper-
ating.
This could
result
in either
inadequate
air delivery
or back
drafts.
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. lB.
FIG.
lC.
Ducting
straight
up
through
the
roof
using
3-1/4"
x 10" rectangular
duct.
(For single
story
installations.)
FIG. 1D. 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.
1E. Straight
up through
the roof
using
3-1/4"
x 10" to 6"
round duct transition
and 6" round duct (for single-story
installa-
tions).
FIG. 1F. Straight
up through
the roof using
7" round
duct
(for
single-story
installations).
Requires
optional
damper
