Wolf Pro wall hoods provide the ultimate in ventila-
tion. With standard elements like heat sentry and dual
setting halogen lighting, Wolf elevates the need for
ventilation to an enjoyable perk.
This 22" (559) deep model is the low-profile version,
42" (1067) wide and available in the classic stainless
steel finish. You also have the option of a decorative
rail. While a classic stainless steel rail is standard on
the (R) model, a platinum or brass rail is available as a
sales accessory.
For optimal performance, a Pro 27" (686) deep wall
hood is recommended for use with ranges and range-
tops that contain a charbroiler or griddle.
Wolf Pro low-profile wall hoods are
10" (254) high by 22" (559) deep and
come in the classic stainless steel finish.
Rail option hoods (R) include a classic
stainless steel decorative rail and stand-
offs. Optional platinum or brass rails
match dual fuel range bezels. These Pro
low-profile wall hoods are sold as a shell
only; internal, in-line and remote blower
options are available.

INSTALLATION NOTES
Refer to the illustrations and specifications
for overall dimensions and installation specifics.
For optimal performance, a Pro 27" (686)
deep wall hood is recommended for use with
ranges and rangetops that contain a charbroiler
or griddle.
The hood should be as least as wide as the
cooking surface. It is recommended that the
hood overlap the cooking surface by 3" (76) on
either side.
Installation of all Pro wall 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 low-profile wall hoods are shipped
without the 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 end of this section for
Pro ventilation recommendations and blower
options.
IMPORTANT NOTE: Install this ventilation hood
only with a Wolf blower.
Pro wall 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. Locate electri-
cal within the shaded area shown in the Instal-
lation illustration. Note that the location of the
electrical supply will differ between vertical and
horizontal discharge blowers.
You must follow all National Electrical Code
regulations. In addition, be aware of local codes
and ordinances when installing your service.
Vertical or horizontal discharge is applicable
on the low-profile wall hoods.
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.

Models W302210I and W362210I come with
internal blowers, all other Wolf Pro low-profile
wall hoods are shipped without the blower
assembly. Internal, in-line or remote blower
assemblies are available. The remote blower can
be mounted on the roof or an exterior wall. Refer
to the illustration below for ducting options.
Pro low-profile wall hoods have an adjustable
discharge location that can run vertically or
horizontally. Horizontal discharge is applicable on
low-profile wall hoods (excluding Models
W302210I and W362210I) using a remote
blower.
Refer to the Pro ventilation charts at the end of
this section for recommendations and blower
options.

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.

product. Always consult a qualified HVAC Engineer for specific applications.
