ELECTRICAL REQUIREMENTS
All Wolf ventilation products require a separate, grounded
electrical supply. Refer to the electrical requirements for
your specific ventilation product on pages 14–41. Locate
the electrical supply within the shaded area shown in the
installation illustration.
You must follow all National Electrical Code regulations.
In addition, be aware of local codes and ordinances when
installing your service.
IMPORTANT NOTE:
A ground fault circuit interrupter
(GFCI) is not recommended and may cause interruption
of operation.
CUSTOM HOOD APPLICATIONS
A custom decorative hood, used with pro hood liners,
can be created out of wood, plaster, tile or metal to match
virtually any design theme. The shape of the decorative
hood is not critical as long as the hood liner fits com-
pletely inside the hood. The decorative hood and liner
must fit together at the bottom edge in both width and
depth. The height of the hood does not have to match the
height of the liner. Interior dimensions of the decorative
hood must exceed exterior dimensions of the liner. Refer
to specifications for pro hood liners on pages 40–41.

DUCTWORK CONSIDERATIONS
IMPORTANT NOTE:
Unless used in a recirculating applica-
tion, Wolf ventilation hoods and downdrafts must be
vented to the outside. Use only rigid metal ducting.
Typically, wall-mounted ventilation hoods can be vertical
or horizontal discharge, while wall chimney hoods, island
hoods and hood liners are vertical discharge only. For
some wall hoods, an accessory horizontal discharge kit is
required. In a horizontal discharge application, additional
framework may be needed to accommodate the remote
blower. Wolf downdraft systems have an adjustable
discharge that will allow you to negotiate ducting around
floor joists and other obstacles.
Depending on the specific installation, ductwork can run
through the roof, external wall or eave. Ductwork through
an eave requires an internal blower. Refer to individual
specifications for each ventilation hood on pages 14–41.
A straight, short duct run with a limited number of elbows
and transitions will allow the hood or downdraft to perform
most efficiently. Wolf ventilation hoods will operate most
efficiently when ductwork does not exceed 50'
(15 m)
in
length, 40'
(12 m)
for downdrafts. Refer to the chart on
page 9 to calculate total duct length.
IMPORTANT NOTE:
Consult a qualified HVAC professional
for specific installation and ductwork applications.
