INSTALLATION NOTES
Refer to the illustrations and specifications
for overall dimensions and installation specifics.
Wolf Pro island hoods are recommended for
use with any Wolf cooking appliance. The hood
must overlap the cooking surface by a minimum
of 3" (76) on either side.
Installation of all Pro island hoods should be
30" (762) to 36" (914) from the bottom of the
hood to the countertop. Follow the dimensions
shown in the Installation illustration.
Wolf Pro island hoods are shipped without a
blower assembly. Internal, in-line and remote
blower assemblies are available. Blower options
also vary with the volume of air that needs to
be moved and the length of the duct run. Refer
to the charts at the end of this section for Pro
ventilation recommendations and blower
options.
IMPORTANT NOTE: Install this ventilation hood
only with a Wolf blower.
Pro island hoods require a separate,
grounded 110/120 V AC, 60 Hz power supply.
The service should have its own 15 amp circuit
breaker. Placement of the electrical supply is
not critical, as long as you provide a minimum
of 6" (152) of 120 V AC, 60 Hz power cable.
Location of electrical is centered through the
top of the hood as shown in the Installation
illustration on page 4.
You must follow all National Electrical Code
regulations. In addition, be aware of local codes
and ordinances when installing your service.
Refer to the installation instructions shipped
with each Wolf product for detailed specifica-
tions. This information can also be found on
our website, wolfappliance.com.

WOLF BLOWER ASSEMBLIES
A ventilation system must include a blower
assembly. With a few exceptions where internal
blowers are included, Wolf ventilation hoods and
downdrafts are shipped without the blower
assembly. An internal, in-line or remote blower
assembly must be selected to accommodate the
cooking appliance, CFM requirements and home-
owner preferences. Internal, in-line and remote
blower assemblies are available as sales acces-
sories through your Wolf dealer.
Wolf internal, in-line and remote blowers are for
use with Wolf cooktop hoods, downdraft
systems and Pro ventilation hoods and hood
liners.
IMPORTANT NOTE: Use only a Wolf blower
with all Wolf ventilation products.
Internal blowers are mounted inside the hood
canopy or downdraft blower box. In-line blowers
are mounted in between the hood and the
exterior of the home. Remote blowers can be
mounted on the roof or in some cases, on an
exterior wall. Refer to the illustrations below for
dimensions of Wolf in-line and remote blowers.
Ventilation recommendation charts on the
following pages provide minimum CFM recom-
mendations according to the cooking appliance
and ventilation system used and blower options
for each specific ventilation hood or downdraft.
