Dimension Information (in inches)
Hood Exhaust Duct
Outside ventilation requires a 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 a round duct is required, a rectangular-to-round transition adaptor must be used.
Do not use less than a 6” diameter duct.
REAR EXHAUST:
If a rear or horizontal exhaust is to be used, care should be taken to align exhaust
with the space between studs, or wall should be prepared at the time it is constructed
by leaving enough space between the wall studs to accommodate exhaust.
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 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 length of all transitions and adaptors plus
the length of all straight duct sections. The chart below
shows the approximate feet of equivalent length of some
typical ducts.
