Wolf Pro wall hoods provide the ultimate in
ventilation. With standard elements like heat sentry
and dual setting halogen lighting, Wolf elevates the
need for ventilation to an enjoyable perk.
Pro 27" (686) deep wall hoods are 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 (R) models, platinum or brass rails are
available to match the bezels of our dual fuel ranges
and sealed burner rangetops.
The deepest of the Pro wall hoods, this 27" (686)
model provides an additional exclusive feature – heat
lamps.
Pro wall ventilation hoods are recommended for use
with all Wolf cooking appliances. For optimal perform-
ance, a Pro 27" (686) deep wall hood is recommended
for use with ranges and rangetops that contain a
charbroiler or griddle.
Wolf Pro 27" (686) deep wall hoods
are available in the classic stainless steel
finish. Rail option hoods (R) come with a
classic stainless steel decorative rail and
stand-offs. Optional platinum or brass
rails match dual fuel range bezels. Pro
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.
Wolf Pro wall ventilation hoods are recom-
mended for use with any Wolf cooking appli-
ance, and should be at least as wide as the
cooking surface. It is recommended that the
hood overlap the cooking surface by 3" (76) on
either side.
For optimal performance, a Pro 27" (686)
deep wall hood is recommended for use with
ranges and rangetops that contain a charbroiler
or griddle.
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 wall 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 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.
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.

CFM recommendations are based on total Btu/hr output. Wolf recommends 1 CFM per 100 Btu/hr (.03 kW). Additional CFM may be
required for long duct runs.
