Rail Option
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 as least as wide as the
cooking surface. It is recommended that the
hood overlap the cooking surface by 3" (76) on
either side.
IMPORTANT NOTE: 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 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 wall 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 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 enough 120 V AC, 60 Hz
power cable to make the electrical connection.
Locate electrical within the shaded area 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 27" (686) deep wall 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 27" (686) deep wall hoods have a vertical
discharge. A horizontal discharge kit is available
as a sales accessory.
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 27" (686) deep
wall hoods must be vented to the outside. Use
only metal ductwork.
Refer to the illustration below for ducting
considerations for Pro 27" (686) deep wall
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 27" (686) deep wall hood.
