Hood exhaust
When venting exhaust to the outside, hood exhaust
ducts will be required. 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.
The hood exhaust has been designed to mate with a
standard 3¼" x 10" (82 x 254 mm) rectangular duct. If a
round duct is required, a rectangular-to-round transition
adaptor must be used. Do not use less than a 6"
(152 mm) diameter duct.
For satisfactory air movement, the total duct length of
