INSTALLATION NOTES
Refer to the illustrations and specifications
for overall dimensions and installation specifics.
Wolf Pro island ventilation hoods are recom-
mended for use with any Wolf cooking appli-
ance. The hood must overlap the cooking
surface by a minimum of 3" (76) on either side.
Installation of all Pro ventilation 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 on page 4.
Wolf Pro island hoods are shipped without a
blower assembly. Internal, in-line or 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 enough 120
V AC, 60 Hz power cable to make the electrical
connection. 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.

DUCTING CONSIDERATIONS
Wolf Pro island hoods are shipped without the
blower assembly. Internal, in-line and remote
blower assemblies are available.
IMPORTANT NOTE: Install this ventilation hood
only with a Wolf blower.
Pro island hoods have a vertical discharge
location with 10" (254) round duct. A transition
with backdraft damper is included. The hood will
operate most efficiently when ductwork does
not exceed 50' (15 m) in length.
Local building codes may require the use of
make-up air. Consult your local HVAC profes-
sional for specific requirements in your area.
IMPORTANT NOTE: Wolf Pro island hoods
must be vented to the outside. Use only metal
ductwork.
Refer to the illustration below for ducting
considerations for Pro island hoods.

WOLF BLOWER ASSEMBLIES
A ventilation system must include a blower
assembly. Wolf ventilation hoods 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 homeowner preferences.
Internal, in-line and remote blower assemblies
are available as sales accessories through your
Wolf dealer.
IMPORTANT NOTE: Use only a Wolf blower
with all Wolf ventilation products.
Internal blowers are mounted inside the hood
canopy. 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 illustra-
tions below for dimensions of Wolf in-line and
remote blowers.
Pro ventilation recommendation charts on the
following page provide minimum CFM recom-
mendations according to the cooking appliance
and ventilation hood used and blower options
for each specific Pro island hood.
