Wolf Ventilation 3
wolfappliance.com/specs
Wolf Ventilation. Ventilation is an integral part of any kitchen. Proper ventilation provides a cleaner, healthier, more
enjoyable cooking environment by removing moisture, odor and unhealthy by-products of combustion, including carbon
monoxide. Proper ventilation is essential for maintaining a healthy indoor environment and minimizing airborne health risks.
Ventilation can provide a dramatic focal point for your kitchen or it can be concealed for an integrated look. Wolf ventilation
systems are precisely crafted for both function and design.
Choosing the proper ventilation system is one of the most important decisions you can make when designing your kitchen.
Wolf has ventilation products to satisfy all needs and preferences. When selecting a ventilation system, it is important to
note that Wolf ventilation systems are divided into two categories: cooktop ventilation and pro ventilation.
Cooktop ventilation. Pro ventilation.

COOKTOP OR PRO VENTI ATION
Wolf cooktop ventilation hoods can be used with Wolf
induction, electric and gas cooktops and integrated
modules. Wolf downdraft systems can be used with Wolf
framed induction, framed electric and gas cooktops and
some integrated modules. Downdrafts cannot be installed
with unframed induction and unframed electric cooktops,
and steamer and fryer modules. They are not recom-
mended for use with the grill module.

Selecting a Ventilation System 5
wolfappliance.com/specs
Selecting a Ventilation System
UPDRAFT OR DOWNDRAFT
The choice between updraft ventilation and downdraft
ventilation will depend on several factors, most notably
the cooking appliance being used as well as the type of
installation and installation location. Updraft ventilation,
or an overhead hood, will typically be a more effective
ventilation option. Cooking vapors naturally rise, making it
easier to collect and remove them from the cooking area.
Wolf downdraft systems provide another effective ventila-
tion option. The 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 either
not wanted or is not a viable option.
WIDTH GUIDE INES
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 down-
draft 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, perform-
ance may be compromised.
For optimal performance, cooktop hoods should be
mounted 24" (610) to 30" (762) from the bottom of the hood
to the countertop. For optimal performance, pro hoods
should be mounted 30" (762) to 36" (914) from the bottom
of the hood to the countertop. Refer to individual specifi-
cations for each ventilation hood on pages 14–41.
CEI ING HEIGHT
Before selecting a Wolf ventilation hood, check the instal-
lation 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
floor-to-countertop height, plus the recommended hood
mounting height (bottom of the hood to the countertop),
plus the height of the hood. Refer to individual specifica-
tions for each ventilation hood on pages 14–41.
Excess ceiling height can be filled using an accessory
flue extension (available for some cooktops hoods) or a
stainless steel duct cover (pro hoods). The space can also
be adjusted by raising or lowering your hood within the
specified mounting height for your hood.
For additional ceiling height guidelines for cooktop wall
and island hoods, refer to page 15.

Selecting a Ventilation System 6
INTERNA , IN- INE OR REMOTE B OWER
With the exception of some cooktop low-profile hoods
and some downdrafts, Wolf ventilation products are
shipped without the blower assembly. An internal, in-line
or remote blower must be selected to accommodate the
Wolf cooking appliance.
The blower will vary in size, which is dictated by the
cooking surface, the volume of air that needs to be moved
and the length of the duct run.
RECIRCU ATING VENTI ATION
Recirculating ventilation units are installed on top of a
ventilation hood with no ductwork required. Recirculating
units recycle the air through a charcoal filter and return it
to the kitchen. Wolf recirculating units are for use with
cooktop low-profile hoods with an internal blower and
some pro wall hood models. Recirculating units should
not be used with ranges or rangetops that contain a char-
broiler or griddle. Refer to specifications for recirculating
ventilation on pages 42–43.
IMPORTANT NOTE: 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.
Selecting a Ventilation System
COOKING STY E
The appropriate airflow capacity is determined by the
cooking space and cooking style. reater exhaust
capacity is required to handle 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 increas-
ing the capture area with a hood that exceeds the cooking
surface by 3" (76) on each side.
If the cooking surface is in an island or peninsula, a higher
airflow capacity hood can provide better capture for cross
currents, or if the hood needs to be mounted higher.
Downdraft ventilation systems are also a good alternative.
VENTI ATION PERFORMANCE
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 are based on the cooking appliance output.
Wolf suggests 1 CFM per 100 Btu (.03 kW).
The chart on page 10 provides CFM for all Wolf cooking
appliances.

E ECTRICA REQUIREMENTS
All Wolf ventilation products require a separate, grounded
electrical supply. Refer to the electrical requirements for
your specific ventilation product on pages 14–41. Locate
the electrical supply within the shaded area shown in the
installation illustration.
You must follow all National Electrical Code regulations.
In addition, be aware of local codes and ordinances when
installing your service.
IMPORTANT NOTE: A ground fault circuit interrupter
( FCI) is not recommended and may cause interruption
of operation.
CUSTOM HOOD APP ICATIONS
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 fits com-
pletely inside the hood. The decorative hood and liner
must fit 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. Interior dimensions of the decorative
hood must exceed exterior dimensions of the liner. Refer
to specifications for pro hood liners on pages 40–41.

Selecting a Ventilation System
DUCTWORK CONSIDERATIONS
IMPORTANT NOTE: Unless used in a recirculating applica-
tion, 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 and hood liners 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
floor joists and other obstacles.
Depending on the specific installation, ductwork can run
through the roof, external wall or eave. Ductwork through
an eave requires an internal blower. Refer to individual
specifications for each ventilation hood on pages 14–41.
A straight, short duct run with a limited number of elbows
and transitions will allow the hood or downdraft to perform
most efficiently. Wolf ventilation hoods will operate most
efficiently when ductwork does not exceed 50' (15 m) in
length, 40' (12 m) for downdrafts. Refer to the chart on
page 9 to calculate total duct length.
IMPORTANT NOTE: Consult a qualified HVAC professional
for specific installation and ductwork applications.

Ventilation Made Easy
After choosing your ventilation hood or downdraft, follow
this three-step process to determine your blower needs:
Step 1) Determine the Duct Run
Step 2) Determine the CFM
Step 3) Select a Blower Assembly
Step 1: Determine the Duct Run
Check local codes. Consult a qualified HVAC professional
to ensure that all local codes are followed. Always refer to
installation instructions for your specific Wolf ventilation
product.
Minimize the duct run and number of elbows and transi-
tions. The length of the duct run and number of elbows
and transitions can have a significant effect on ventilation
performance. Keep the duct run as short as possible and
limit the number of elbows and transitions.
Do not place elbows and transitions back-to-back.
Whenever possible, include a minimum 15" (381) straight
ducting between elbows and transitions. Elbows and
transitions placed too close to each other will cause a
decrease in ventilation performance.
Use recommended duct sizes. Depending on the specific
ventilation product, Wolf recommends 8" (203) or 10" (254)
ducting. Smaller duct sizes will significantly reduce
ventilation performance. Refer to individual specifications
for each ventilation product on pages 14–41.
Do not use flexible metal ducting. Flexible metal ducting
will increase air resistance and is not recommended by the
National Uniform Mechanical Code Standards.
Do not use butt joints. Whenever possible, use male and
female connections with the male end pointing in the
direction of the airflow. Tightly tape joints to maximize
ventilation performance.
Cold weather installations. Cold weather installations
may require an additional backdraft damper to minimize
backward flow of cold air. It should be placed as close to
the roof or wall cap as possible. All Wolf ventilation hoods,
except low-profile wall hoods, come with a backdraft
damper connected to the transition. Downdraft systems
do not have a backdraft damper.
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 perform-
ance. Solutions include using a higher CFM blower and
increasing the duct size.
Make-up air may be required. Most newer homes have
tightly sealed doors and windows. Make-up air may be
needed to replace the air removed by the ventilation
system. Many heating and air conditioning systems
provide make-up air. Opening a window or door can be
an option but may be less effective. Consult a qualified
HVAC professional for specific applications.
Recirculating ventilation. Recirculating units recycle the
air through a charcoal filter 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 ductwork to the
outside is not an option, and only if local codes allow it.
Refer to specifications for recirculating ventilation on
pages 42–43.

Step 1: Determine the Duct Run
Determining the equivalent duct length. Determine the
equivalent duct length for your installation using the
equivalent duct lengths for commonly used ducting. Refer
to the chart on the following page. The equivalent duct
length is calculated as follows:
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.

Step 3: Select a Blower
WO F B OWER ASSEMB IES
With the exception of some cooktop low-profile hoods
and some downdrafts, Wolf ventilation products are
shipped without the blower assembly. An internal, in-line
or remote blower must be selected to accommodate the
Wolf cooking appliance. Wolf blower assemblies are
available through your authorized Wolf dealer. For local
dealer information, visit the find a showroom section of
our website, wolfappliance.com.
IMPORTANT NOTE: Wolf ventilation products must be
installed only with a Wolf blower.
The chart on the following pages provides blower options
for all cooktop and pro ventilation products.
Installation instructions shipped with each Wolf blower
assembly provide detailed specifications.
INTERNA B OWERS
Internal blowers are mounted inside the hood canopy or
downdraft blower box and provide the least disruption to
the exterior of the home.
Internal blowers are available for all Wolf cooktop and pro
ventilation products. Refer to specifications for Wolf
internal blowers on pages 44–48.
IN- INE B OWERS
In-line blowers are mounted between the hood and the
exterior of the home. Ductwork runs from the hood and
connects to the blower. More ductwork is attached to the
other side of the blower and runs to the exterior of the
home. This is a great option for those who do not want the
blower mounted inside the hood but cannot, or prefer not
to mount a remote blower on the exterior of the home.
In-line blowers are available for all Wolf cooktop and pro
ventilation products. Refer to specifications for Wolf in-line
blowers on pages 49–50 with additional planning informa-
tion on pages 58–59.
REMOTE B OWERS
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.
Some blower noise is considered normal while the blower
is operational. If noise is a concern, a remote blower is
recommended. To reduce noise further for remote blower
applications, an attenuator may be necessary.
Remote blowers are available for all Wolf cooktop and pro
ventilation products. Refer to specifications for Wolf
remote blowers on pages 51–57 with additional planning
information on pages 60–62.
