SELECTING A VENTILATION SYSTEM
Selecting a Ventilation System
When selecting a ventilation system, start by choosing the
proper Wolf ventilation product, determined by the type of
cooking appliance used and the following considerations:
• Cooktop or pro ventilation
• Updraft or downdraft
• Width guidelines
• Hood mounting height
• Ceiling height
• Cooking space / cooking style
• Ventilation performance
• Internal, in-line, or remote blower
• Ducting considerations
• Electrical requirements
• Recirculating application
• Custom hood application
IMPORTANT NOTE: Wolf cooking products do not require
ventilation when installed according to the installation
instructions. Recommendations and suggestions in this
guide are for performance only.

SELECTING A VENTILATION SYSTEM
Selecting a Ventilation System
COOKTOP OR PRO VENTILATION
One of the primary considerations in choosing a ventilation
product is the type of cooking appliance used. Wolf offers
both cooktop ventilation and pro ventilation. Cooktop ventilation includes wall hoods, island hoods, ceiling-mounted
hoods, under-cabinet hood inserts, and downdraft systems.
Pro ventilation includes wall hoods, island hoods, hood
liners, and outdoor wall hoods.
Wolf cooktop ventilation hoods and downdrafts are
designed for use with induction, electric, and gas cooktops
Wolf pro ventilation hoods and liners can be used with all
cooking appliances, including ranges and rangetops.
A downdraft system can also be used with sealed burner
rangetop models SRT304 and SRT366. The outdoor wall
hood is specically designed for outdoor use.
An accessory trim kit is required for installation of a contemporary cooktop or sealed burner rangetop with a downdraft.
It is avail able through an authorized Wolf dealer. For local
dealer information, visit the nd a showroom section of our
website, wolfappliance.com.
and modules. Some exceptions apply for downdrafts.
The chart below provides a reference of Wolf ventilation
products recommended for use with specic Wolf cooking
appliances.

The choice between updraft ventilation and downdraft
ventilation will depend on several factors, most notably the
cooking appliance, type of installation, and location. Updraft
ventilation, or an overhead hood, is typically a more effective ventilation option. Cooking vapors naturally rise, making
it easier to collect and remove them from the cooking area.
With downdraft systems, a telescopic downdraft chimney
rises up from the countertop and draws cooking vapors
away from the cooking surface. Downdraft ventilation is a
great option in installations where an overhead hood is not
desired or is not a viable option.
WIDTH GUIDELINES
For wall installations, the width of the hood should be at
least as wide as the cooking surface. Where space is not
restricted, a wider hood can be used to increase the capture
area.
Island and peninsula installations require a greater capture
area. Island hoods should exceed the width of the cooking
surface by a minimum of 3"
(76) on each side.
For downdraft ventilation systems, the width of the downdraft should match the width of the cooktop.
HOOD MOUNTING HEIGHT
Proper mounting height is very important. If a ventilation
hood is mounted too low, access to the cooking surface
may be restricted. If a hood is mounted too high, performance may be compromised.
For optimal performance, pro hoods should be mounted
(762) to 36" (914) from the bottom of the hood to the
30"
counterop. The ceiling-mounted hood should be mounted
(914) to 84" (2114) from the bottom of the hood to the
36"
countertop. The cooktop hood and and under-cabinet hood
insert should be mounted 24"
(610) to 36" (914) from the
bottom of the hood to the countertop. The outdoor wall
hood should be mounted 36"
(914) to 42" (1067) from the
bottom of the hood to the countertop.
CEILING HEIGHT
Before selecting a Wolf ventilation hood, check the installation site for adequate ceiling height, or any extra space that
may remain after proper installation of the hood and cooking
appliance. This can be determined by adding the oor-tocountertop height, plus the recommended hood mounting
height (bottom of the hood to the countertop), plus the
height of the hood.
Excess ceiling height can be lled using an accessory ue
extension or a stainless steel duct cover for pro hoods. The
space can also be adjusted by raising or lowering the hood
within the specied mounting height.
COOKING SPACE / COOKING STYLE
The appropriate airow capacity is determined by the
cooking space and cooking style. If the cooking surface
is in an island or peninsula, a higher airow capacity hood
can provide better capture for cross currents, or if the hood
needs to be mounted higher. Downdraft ventilation may also
be an option.
Greater exhaust capacity is required to handle the moisture
generated by boiling large pots of water or the grease and
smoke from grilling or frying. Cooking with high heat or
cooking aromatic foods may require additional CFM and
increasing the capture area by using a hood that exceeds
the cooking surface by 3"
VENTILATION PERFORMANCE
(76) on each side.
Ventilation performance is measured in cubic feet per
minute, or CFM. The higher the CFM, the greater the
amount of air that is evacuated through the ventilation
system. CFM suggestions are based on the cooking appliance output.

Selecting a Ventilation System
INTERNAL, IN-LINE, OR REMOTE BLOWER
All Wolf ventilation products are shipped without the blower
assembly. An internal, in-line, or remote blower must be
selected to accommodate the cooking appliance and ventilation product.
The blower will vary in size (CFM), which is dictated by the
cooking surface, the volume of air that needs to be moved,
and the length of the duct run.
Internal blowers are mounted inside the hood canopy or
blower box and provide the least disruption to the exterior
of the home.
In-line blowers are connected to the duct run between the
hood and the exterior of the home. This is a great option if
mounting the blower inside the hood or on the exterior of
the home is not desired or is not a viable option.
Remote blowers can be mounted on the roof or, in some
cases, on an exterior wall. A remote-mounted blower will
minimize the amount of blower noise but will not eliminate
the noise completely. If noise is a concern, a remote blower
is recommended.
Internal, in-line, and remote blowers are available for all
Wolf cooktop and pro ventilation products except the undercabinet hood inserts which offer only an internal blower
option.
DUCTING CONSIDERATIONS
IMPORTANT NOTE:
Unless used in a recirculating application, Wolf ventilation hoods and downdrafts must be vented
to the outside. Use only rigid metal ducting.
Typically, wall-mounted ventilation hoods can be vertical
or horizontal discharge, while wall chimney hoods, island
hoods, hood liners, and outdoor wall hoods are vertical
discharge only. For some wall hoods, an accessory horizontal discharge kit is required. In a horizontal discharge
application, additional framework may be needed to accommodate the remote blower. Wolf downdraft systems have an
adjustable discharge that will allow you to negotiate ducting
around oor joists and other obstacles.
Depending on the specic installation, ducting can run
through the roof, external wall, or eave. A remote blower can
not be ducted through an eave.
A straight, short duct run with a limited number of elbows
and transitions will allow the hood or downdraft to perform
most efciently. Wolf ventilation hoods will operate most
efciently when the duct run does not exceed 50' (15 m) in
length, 40' (12 m) for downdrafts. To calculate the total duct
length, refer to page 8.
ELECTRICAL REQUIREMENTS
All Wolf ventilation products require a separate grounded
electrical supply. Installation must comply with all applicable
electrical codes.
6 | Wolf Customer Care 800.222.7820
For all hoods except the outdoor wall hood, a ground fault
circuit interrupter (GFCI) is not recommended and may
cause interruption of operation. For the outdoor wall hood, a
ground fault circuit interrupter is required to reduce the risk
of electrical shock.

SELECTING A VENTILATION SYSTEM
Selecting a Ventilation System
RECIRCULATING APPLICATION
Recirculating units recycle the air through a charcoal lter
and return it to the kitchen. This type of ventilation will not
remove heat, moisture, or combustion gases from the air.
It will also be less effective in reducing odors and smoke.
Recirculating units should only be used in applications
where ducting to the outside is not an option, and only if
local codes allow it.
Wolf recirculating units are for use with cooktop hoods and
downdrafts with an internal blower and some pro wall hood
models. Recirculating units should not be used with ranges
or rangetops that contain a charbroiler or griddle.
CUSTOM HOOD APPLICATION
A custom decorative hood, used with pro hood liners, can
be created out of wood, plaster, tile, or metal to match virtually any design theme. The shape of the decorative hood is
not critical as long as the hood liner ts completely inside
the hood. The decorative hood and liner must t together at
the bottom edge in both width and depth. The height of the
hood does not have to match the height of the liner.
Ventilation Made Easy
After choosing the proper ventilation hood or downdraft,
follow this three-step process to determine your blower
needs to complete the ventilation system:
• Step 1: Determine the Duct Run
• Step 2: Determine the CFM
• Step 3: Select a Blower

DETERMINE THE DUCT RUN
Step 1: Determine the Duct Run
IMPORTANT NOTE: Consult a qualied HVAC professional
for specic installation and ducting applications.
Check local codes: Consult a qualied HVAC professional
to ensure all applicable codes are followed. Refer to the
installation guide for your specic Wolf ventilation product.
Minimize the duct run: The length of the duct run and
number of elbows and transitions can have a signicant
effect on ventilation performance. Keep the duct run as
short as possible and limit the number of elbows and transitions. Do not use exible metal ducting.
Elbows and transitions: Do not place elbows and transitions back-to-back. Whenever possible, include a minimum
(381) straight ducting between elbows and transitions to
15"
increase ventilation performance.
Use recommended duct sizes: Depending on the specic
ventilation product, Wolf recommends 6"
(254) ducting. Smaller duct sizes will signicantly reduce
10"
(152), 8" (203), or
ventilation performance.
Cold weather installations: Cold weather installations may
require an additional backdraft damper to minimize backward ow of cold air. All Wolf ventilation hoods, except
low-prole wall hoods, come with a backdraft damper connected to the transition. Downdraft systems do not have a
backdraft damper.
Equivalent duct length: Determine the equivalent length of
the duct run using the equivalent duct lengths for commonly used ducting listed in the chart on the following
page. Follow these steps and use the chart to calculate the
equivalent duct length:
1 Compute the length of all straight ducting.
2 Compute the equivalent duct length of all elbows,
transitions and caps.
3 Add equivalent lengths for all sections of the duct run.
High altitudes: Ventilation systems are less effective at
altitudes above 5,000'
(1524 m). At these altitudes, you
should estimate a 20–25% reduction in CFM performance.
A higher CFM blower and increasing the duct size is
recommended.
Make-up air: Make-up air may be required to replace air
removed by the ventilation system. Consult a qualied
HVAC professional for specic applications.

DETERMINE THE CFM
Step 2: Determine the CFM
Ventilation performance is measured in cubic feet per
minute, or CFM. The chart below provides CFM suggestions specic to the Wolf cooking appliance and ventilation
system used. To maximize airow and performance, specify
a blower to match or exceed the CFM listed.
Additional CFM may be required for long duct runs and
ranges or rangetops with a charbroiler or griddle. When
determining the proper CFM for your installation, take into
consideration the equivalent duct length calculated in Step 1.
IMPORTANT NOTE: Consult a qualied HVAC professional
All Wolf ventilation products are shipped without the blower
assembly. An internal, in-line, or remote blower must be
selected to accommodate the cooking appliance and ventilation product. Wolf ventilation products must be installed
