FOR YOUR SAFETY:
A WARNING - Before beginning the
installation, switch power off at service panel and lock the
service disconnecting means to prevent power from being
switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent
warning device, such as a tag, to the service panel.
A WARNING - To REOUCE THE RISK
OF FIRE, ELECTRICSHOCKOR INJURY TO PERSONS,
OBSERVETHE FOLLOWING:
A. Installationwork and electricalwiring must be done by
qualifiedperson(s)inaccordancewith all applicablecodes
and standards,includingfire-rated construction.
B. Sufficientair is neededfor proper combustion and
exhaustingof gasesthrough the flue (chimney)of fuel
burning equipment to prevent back drafting. Followthe
heating equipment manufacturer'sguideline and safety
standardssuch as those publishedby the National Fire
ProtectionAssociation(NFPA), the American Societyfor
Heating,Refrigerationand Air ConditioningEngineers
(ASHRAE) and the localcode authorities.
C. When cutting or drilling into wall or ceiling,do not damage
electricalwiring and other hidden utilities.
D. Ductedfans must always be vented to the outdoors.

DUCTWORK REQUIREMENTS
NOTE:Read the ductwork sections only if you do not have
existing ductwork. If you have existing ductwork, skip to
the "Damage" section end proceed.
The venting system must exhaust to the outside,
This hood can be vented vertically through upper cabinets
or horizontally through an outside wall. Ductwork is not
included.
Exhaust connection:
The hood exhaust has been designed to mate with
standard 3¼" x 10" rectangular ducting.
If a 7" round duct is required, a rectangular-to-round
transition adaptor must be used*. Do not use less then a
7" diameter duct.
Maximum duct length:
For satisfactory air movement, the total duct length of a
3¼" x 10" rectangular should not exceed 65 equivalent feet.
NOTE:It's important that ducting 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.
Elbows, transitions, wall and roofcaps, etc.,
present additional resistance to airflow and are equivalent
to a section of straight duct 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 charts on the
following pages show you how to calculate total equivalent
ductwork length using the approximate feet of equivalent
length 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 the tin snips, in
order to allow free movement of the
damper. Equivalent lengths of duct
pieces are based on actual tests and
reflect requirements for good venting
performance with any hood.
