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" rect-
angular duct. If round duct is required, a rectangular-to-round transition adaptor must be used. Do not use
less than 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 constructed by leaving enough space between
wall studs to accommodate exhaust.
MAXIMUM DUCT LENGTH: For satisfactory air movement, the total duct length of 3 1/4" x 10" rectan-
gular or 6" diameter round duct should not exceed 140 equivalent feet.
ELBOWS, TRANSITIONS, WALL AND ROOF CAPS, ETC., present additional resistance to airflow 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. See Fig-
ure 2.
