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 specically 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.

SELECTING A VENTILATION SYSTEM
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, 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 specied mounting height.
COOKING SPACE / COOKING STYLE
The appropriate airow capacity is determined by the cooking space and cooking style. If the cooking surface is in an island or peninsula, a higher airow 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
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 specic 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 efciently. Wolf ventilation hoods will operate most efciently 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 qualied HVAC professional
for specic installation and ducting applications.
Check local codes: Consult a qualied HVAC professional to ensure all applicable codes are followed. Refer to the installation guide for your specic Wolf ventilation product.
Minimize the duct run: The length of the duct run and number of elbows and transitions can have a signicant 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 specic ventilation product, Wolf recommends 6"
(254) ducting. Smaller duct sizes will signicantly 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-prole 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 qualied HVAC professional for specic 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 specic to the Wolf cooking appliance and ventilation system used. To maximize airow 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.
