Hood Exhaust Duct
Outside ventilation requires
HOOD EXHAUST DUCT.
Read the following carefully.
EXHAUST CONNECTION:
The hood exhaust has been
designed to mate with a
standard 3-1/4” x 10”
rectangular duct.
If round duct is required, a
rectangular-to-round
transition adapter must be
used. Do not use less than a 6”
diameter duct.
REAR EXHAUST: If rear or
horizontal exhaust is to be
used, care should be taken to
align exhaust with space
between studs, or wall should
be prepared at the time it is
comstructed by leaving enough
space between wall studs to
accommodate exhaust.
NOTE: Reference wall
template.
MAXIMUM DUCT LENGTH:
For satisfactory air movement,
the total duct length of 3-1/4” x
10” rectangular or 6” diameter
round duct should not exceed
140 feet of epuivalent duct run.
ELBOWS, TRANSITIONS,
WALL AND ROOF CAPS, etc.,
present additional resistance to
air flow and are equivalent to a
section of straight duct which is
longer than their actual
physical size. When calculating
the total duct length add the
equivalent lengths of all
transitions and adaptors plus
the lengths of all straight duct
sections. The diagram below
shows the approximate feet of
equivalent length of some
typical ducts.
