Ventilation is an integral part of any kitchen. Proper ventilation provides a cleaner, more enjoyable cooking environment by removing the cooking vapors and odors from the cooking area. From downdrafts to 66" (1676) wide wall hoods, Wolf has ventilation products to satisfy all of your customers’ needs and preferences. The chart on the following page gives ventilation recommendations for each product line.

Installation instructions shipped with each Wolf ventilation product provide detailed specifications. These instructions can also be found on our website, wolfappliance.com. Work with a qualified installer or Wolf authorized service center technician to ensure that all local codes are followed. Consult a qualified HVAC engineer for specific installation and ducting applications.

Cooktop or Pro Ventilation

Wolf ventilation systems are divided into two categories: Cooktop ventilation and Pro ventilation. Wolf cooktop wall and island hoods are recommended for use with Wolf induction, electric, gas and integrated cooktops and should be at least as wide as the cooking surface. Wolf downdraft ventilation systems are recommended for use with Wolf framed induction, electric and gas cooktops and some integrated modules. They cannot be installed with unframed induction and electric cooktops and steamer and fryer modules. They are not recommended for use with the electric grill module. A Pro ventilation hood is recommended for use with Wolf dual fuel ranges, gas ranges, sealed burner rangetops and gas rangetops.

A downdraft can be used with sealed burner rangetop Models SRT304 and SRT366. An accessory trim kit (810215) is required for this installation. Contact your dealer for details.

The chart below provides a quick reference of recommended ventilation equipment for specific Wolf cooking products.

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 installation and installation location. Updraft ventilation, or overhead hood, will normally be a more effective ventilation option. Cooking vapors naturally rise, making it easier to collect and remove them from the cooking area.

Wolf downdrafts provide another effective option for ventilation. The 9" (229) telescope rises up from the countertop and draws cooking vapors away from the cooking surface. Downdraft ventilation is a great option in installations where updraft ventilation is either not wanted or is not a viable option.

CFM Recommendations

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 recommendations are based on the cooking appliance output. Wolf recommends 1 CFM per 100 Btu/hr.

The chart on page 53 provides minimum CFM recommendations for all Wolf cooking products.

Internal, In-Line or Remote Blower

A ventilation system must include a blower assembly. Most Wolf ventilation hoods and downdrafts are sold as a shell only. There are a few exceptions where internal blowers are included. An internal, in-line or remote blower assembly must be selected to accommodate the cooking appliance requirements and homeowner preferences.

The charts on pages 55–56 provide blower options for all Cooktop and Pro 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 are mounted on the roof, or in some cases, an exterior wall. Remote mounted blowers 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. Consult a qualified HVAC engineer for specific installation and ducting applications.

Width Guidelines

The minimum hood width recommended for wall installations should be equal to the width of the cooktop or range. If the space is not restricted, a wider hood should be used to increase the capture area.

Island installations require a greater capture area. It is recommended that Wolf island hoods overlap the width of the cooktop or range by a minimum of 3" (76) on either side.

The width of the Wolf downdraft system should match the width of the cooktop.

Ceiling Height

When selecting a Wolf ventilation hood, make sure there is enough ceiling height to accommodate the hood. This can be determined by adding the floor-to-countertop height plus the recommended spacing between the countertop and the bottom of the hood plus the height of the hood. Overall dimensions for all Wolf ventilation products are provided in this guide.

Installation of cooktop wall and island hoods should be 24" (610) to 30" (762) from the bottom of the hood to the countertop. For additional ceiling height guidelines for these chimney-style hoods, refer to pages 19–20.

Installation of Pro wall, wall chimney and island hoods and hood liners should be 30" (762) to 36" (914) from the bottom of the hood to the countertop.

Recirculating Ventilation

Recirculating ventilation units are installed on top of a ventilation hood; no ductwork is 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 Pro wall hood Models PW302210, PW362210, PW302418, PW362418, PW302718 and PW362718.

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.

Electrical Requirements

Wolf cooktop chimney wall and island hoods require a separate, grounded 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 12" (305) of 120 V AC power cable for the wall hood and 6' (1.8 m) for the island hood.

Locate electrical within the shaded area shown in the installation illustration for your model below and on the following page.

IMPORTANT NOTE: A ground fault circuit interrupter (GFCI) is not recommended and may cause interruption of operation.

You must follow all National Electrical Code regulations. In addition, be aware of local codes and ordinances when installing your service.

Blower Considerations

Wolf cooktop chimney wall and island hoods are shipped without the blower assembly. Internal, in-line and remote blower assemblies are available. For wall hoods, the remote blower can be mounted on the roof or an exterior wall. For island hoods, the remote blower will be mounted on the roof.

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.

A remote-mounted blower will minimize the amount of blower noise but will not eliminate the noise completely. All remote blowers will require a transition to a 10" (254) duct.

IMPORTANT NOTE: Install these ventilation hoods only with a Wolf blower.

Refer to the Cooktop Ventilation chart on page 55 for blower options.

Electrical Requirements

Wolf cooktop low-profile wall and island hoods require a separate, grounded 110/120 V AC,

60 Hz power supply. The service should have its own 15 amp circuit breaker.

Locate electrical within the shaded area shown in the installation illustration for your model below and on the following page.

IMPORTANT NOTE: A ground fault circuit interrupter (GFCI) is not recommended and may cause interruption of operation.

You must follow all National Electrical Code regulations. In addition, be aware of local codes and ordinances when installing your service.

Blower Considerations

Wolf low-profile wall and island cooktop hoods are available with an internal blower. Wall hood Models CTEWH36 and CTEWH45 can be used with an in-line or remote blower assembly.

IMPORTANT NOTE: Install these ventilation hoods only with a Wolf blower.

The blower will vary in size and is dictated by the cooking surface, the volume of air that needs to be moved and the length of the duct run. A straight, short duct run with a limited number of elbows and transitions will allow the ventilation hood to perform most efficiently.

A remote mounted blower will minimize the amount of blower noise, but will not eliminate the noise completely.

Refer to the Cooktop Ventilation chart on page 55 for blower options.

Hood Placement

Wolf cooktop wall and island hoods come with a telescopic chimney flue extension that allows you to reach a ceiling height of 8' (2.4 m) to 9' (2.7 m) with a finished look. A flue extension to accommodate 10' (3 m) ceilings is available as a sales accessory for cooktop chimney hoods only.

Installation of the cooktop wall or island hood should be 24" (610) to 30" (762) from the bottom of the hood to the countertop.

To determine placement of the wall or island hood, you must calculate the height of the telescopic chimney flue. Refer to the chart for the minimum and maximum flue extension for your specific hood. Also refer to the illustrations.

IMPORTANT NOTE: Both sections of the telescopic chimney flue must be installed in order for the chimney to be lifted for service.

IMPORTANT NOTE: If the height of the upper flue section is less than 1/2" (13), you will need to modify the flue to affix to the flue attachment brackets.

	CTEWH42I	281/4" (718)	411/2" (1054)

Calculate Chimney Flue Height

1)First measure the total kitchen height from finished floor to finished ceiling height (A). 8' (2.4 m) or 9' (2.7 m) ceilings are standard.

2)Next, measure the height from the finished floor to countertop (B). 36" (914) countertop height is standard.

3)Determine the desired distance from countertop to bottom of hood (C). This dimension must be between 24" (610) and 30" (762).

IMPORTANT NOTE: 8' (2.4 m) ceilings may not permit installation of the wall or island hood at 30" (762) above the countertop.

4)To calculate the chimney flue height (D): D = A – (B + C). This dimension must be between the minimum and maximum flue

extension for your specific hood as shown in the chart.

Ducting Considerations

IMPORTANT NOTE: All Wolf cooktop hoods must be vented to the outside. Use only metal ductwork.

Wolf cooktop wall and island hoods have an 8" (203) round vertical discharge. Ducting can run through the roof, external wall or eave. Ducting through an eave requires an internal blower.

Refer to the illustrations below for ducting considerations.

A straight, short duct run with a limited number of elbows and transitions will allow the ventilation hood to perform most efficiently. Wolf cooktop wall and island hoods will operate most efficiently when ductwork does not exceed 50' (15 m) in length. Refer to the chart on page 52 to calculate total duct length.

Refer to the illustrations below for ducting considerations for cooktop wall and island hoods. Consult a qualified HVAC engineer for specific installation and ducting applications.
