Model IH4227 Cooktop Island Hood

Dimensions in parentheses are in millimeters unless otherwise specified.

9/06

When your dream kitchen calls for a centralized

cooking surface, the Wolf cooktop island hood is the ideal ventilation companion. The sculpted classic stainless steel shape not only provides the power you expect from Wolf, but also the beauty you have come to appreciate as well.

This ceiling mount cooktop hood is 42" (1067) wide by 27" (686) deep. It has a telescopic chimney flue 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.

The Wolf cooktop island hood is recommended for use with Wolf electric and gas cooktops and integrated modules. For Wolf dual fuel ranges, gas ranges, sealed burner rangetops and gas rangetops, a Pro ventilation hood should be used.

The Wolf cooktop island ventilation hood is available in the classic stainless steel finish. It is 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.

The Wolf cooktop island hood is recommended for use with Wolf electric and gas cooktops and integrated modules. The hood should be at least as wide as the cooking surface.

IMPORTANT NOTE: Wolf Pro ventilation hoods should be used with Wolf dual fuel ranges, gas ranges, sealed burner rangetops and gas rangetops.

The Wolf cooktop island hood comes 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.

Installation of the cooktop island hood should be 30" (762) to 36" (914) from the bottom of the hood to the countertop. Follow the dimensions shown in the Installation illustration.

IMPORTANT NOTE: 8' (2.4 m) ceilings will not allow for a 30" (762) maximum height above the countertop. Based on a 36" (914) high countertop, an 8' (2.4 m) ceiling will allow for a maximum height above the countertop of 26

/16" (672).

The Wolf cooktop island hood is shipped without a blower assembly. Internal, in-line and 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 ventilation recommendations and blower options.

IMPORTANT NOTE: Install this ventilation hood only with a Wolf blower.

The Wolf cooktop island hood requires a separate, grounded 110/120 V AC, 60 Hz power supply. The service should have its own 15 amp circuit breaker. Placement of the outlet is not critical, as long as you provide a minimum of 12" (305) of 120 V AC, 60 Hz power cable. Locate electrical supply on the ceiling through the top of the hood.

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

The Wolf cooktop island hood has an 8" (203) round vertical discharge.

Refer to the installation instructions shipped with each Wolf product for detailed specifications. This information can also be found on our website, wolfappliance.com.

COOKTOP HOOD PLACEMENT

The Wolf cooktop island ventilation hood comes with a telescopic chimney flue 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 accesory.

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

/16" (672).

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

To determine placement of the cooktop island hood, you must calculate the height of the telescopic chimney flue. Refer to the illustration and chart below.

To calculate the height of the telescopic chimney flue:

1) First measure A (total kitchen height from finished floor

to finished ceiling height).

2) Next measure B (height from finished floor to countertop).

3) Then determine the minimum C value (distance from countertop to bottom of hood). Refer to the chart for ceiling heights from 8' (2.4 m) to 9' (2.7 m). Dimension C must be greater than 24" (610) and less than 30" (762).

4) To determine the upper flue section height: E=A-(C+B+D).

IMPORTANT NOTE: If dimension E falls between 0" (0) and

/2" (13), you will need to modify the flue to affix to the flue attachment brackets. For ease of installation, Wolf recommends that dimension E be no less than

/2" (13).

Ducting considerations for the Model IH4227 cooktop island hood.

DUCTING CONSIDERATIONS

The Wolf cooktop island hood is shipped without the blower assembly. Internal, in-line or remote blower assemblies are available. The remote blower will be mounted on the roof.

The cooktop island hood has an 8" (203) round vertical discharge. The ventilation hood will operate most efficiently when ductwork does not exceed 40' (12 m) in length. Ducting can run through the roof or through an eave as shown in the illustration below.

Wolf Ventilation Recommendations

Dimensions in parentheses are in millimeters unless otherwise specified.

Remote BLOWER-60REM and BLOWER-90REM

WOLF BLOWER ASSEMBLIES

A ventilation system must include a blower assembly. With a few exceptions where internal blowers are included, Wolf ventilation hoods and downdrafts 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.

Wolf internal, in-line and remote blowers are for use with Wolf cooktop hoods, downdraft systems and Pro ventilation hoods and hood liners.

IMPORTANT NOTE: Use only a Wolf blower with all Wolf 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 can be mounted on the roof or in some cases, on an exterior wall. Refer to the illustrations below for dimensions of Wolf in-line and remote blowers.

Ventilation recommendation charts on the following pages provide minimum CFM recommendations according to the cooking appliance and ventilation system used and blower options for each specific ventilation hood or downdraft.
