Installation Instructions
NOTE: If you need to install ducts, note that tile total
duct length of 3¼" x 10" rectangular or 6" diameter
round duct should not exceed 140 equivalent feet.
Outside ventilation requires a HOOD EXHAUST DUCT.
Read tile following carefllll>
NOTE: It is important that venting be installed using
tile 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:
Tile hood exhaust has been designed to mate with
a standard 3¼" x 10" rectangular duct.
If a round duct is required, a recmngula>to-round
uansition adaptor must be used. Do not use less than
a 6" diameter duct.
Maximum duct length:
For satisfactory' air movement, tile total duct length of
3¼" x 10" rectangular ov 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 tile total
duct length, add tile equivalent lengths of all transitions
and adaptors plus tile length of all straight duct sections.
Tile chart below shows you how to calculate total
equivalent ductwovk length using tile approximate feet
of equivalent length of some b'pical ducts.

IMPORTANT: If a rectangula>to-round transition
adaptor is used, the bottom corners of the damper
will have to be cut to fit, using the tin snips, in order
to allow fi"ee movement of the damper.
