General information NOTE: If you need to install ducts, note that the total duct length of 3 ¼˝ x 10˝ rectangular or 6˝ diameter round duct should not exceed 140 equivalent feet. Outside ventilation requires a HOOD EXHAUST DUCT. Read the following carefully. NOTE: It is important that venting be installed using the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages. Also, make sure dampers swing freely and nothing is blocking the ducts. Exhaust connection: The hood exhaust has been designed to mate with a standard 3 ¼˝ 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. Maximum duct length: For satisfactory air movement, the total duct length of 3 ¼˝ 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 lengths of all transitions and adaptors plus the length of all straight duct sections. The chart below shows you how to calculate total equivalent ductwork length using the equivalent length in feet of some typical ducts.

General information
NOTE
: If you need to install ducts, note that the total duct
length of 3 ¼˝ x 10˝ rectangular or 6˝ diameter round duct
should not exceed 140 equivalent feet.
Outside ventilation requires a HOOD EXHAUST DUCT.
Read the following carefully.
NOTE
: It is important that venting be installed using the
most direct route and with as few elbows as possible.
This ensures clear venting of exhaust and helps prevent
blockages.
Also, make sure dampers swing freely and
nothing is blocking the ducts.
Exhaust connection:
The hood exhaust has been designed to mate with a
standard 3 ¼˝ 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.
Maximum duct length:
For satisfactory air movement, the total duct length of
3 ¼˝ 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 lengths of all transitions and
adaptors plus the length of all straight duct sections. The
chart below shows you how to calculate total equivalent
ductwork length using the equivalent length in feet of some
typical ducts.

IMPORTANT
: If a rectangular-to-round
transition adaptor is used, the bottom
corners of the damper will have to be
cut to fit, using tin snips, to allow free
movement of the damper.

on actual tests and reflect the requirements
for good venting performance with any vent
hood.
