Wolf Induction Cooktop (CTI) Series Installation Information

PRE-INSTALLATION SPECIFICATIONS

This section provides information for service technicians regarding the installation of Wolf Induction Cooktops. For further details, consult the Installation Guide or contact Wolf Appliance Customer Service.

Electrical Requirements - Induction

Maximum Connected Load

Wolf Induction Cooktops require a separate, grounded three-wire service with its own circuit breaker. Installation must comply with National Electrical Codes and all state, municipal, and local codes. A dedicated, grounded circuit protected by a properly sized circuit breaker or time delay fuse is necessary. The cooktops come with a 48" (1219 mm) conduit containing two insulated hot lead conductors (copper) and one insulated ground conductor (copper).

WARNING:

• The appliance must be properly grounded at all times when electrical power is applied.
• Do not ground the appliance with the neutral (white) house supply wire. Use a separate ground wire.
• If aluminum house supply wiring is used, splice appliance copper wire to aluminum house wiring using special connectors designed and certified for joining copper and aluminum. Follow the connector manufacturer's recommended procedure carefully. Improper connection can result in a fire hazard.
• To eliminate the risk of burns or fire from reaching over heated surface units, avoid cabinet storage space located above surface units. If cabinet storage is provided, install a range hood that protects horizontally at least 5" (127mm) beyond the bottom of the cabinets.

Site Preparation

NOTE: Installation of the Wolf induction cooktop must meet the following location requirements. All dimensions listed are minimum requirements for safe operation.

WARNING:

• Failure to locate the cooktop without proper clearances will result in a fire hazard.
• To eliminate the risk of burns or fire by reaching over heated surface units, cabinet storage space located above surface units should be avoided. If cabinet storage is to be provided, the risk can be reduced by installing a range hood that protects horizontally a minimum of 5" (127mm) beyond the bottom of the cabinets.

Location In Countertop (Refer to Figure 2-1)

• A. Minimum flat countertop surface. Must be equal to or greater than cooktop width.
• B. Minimum 1" (25mm) wide clearance from the cooktop side edge to any combustible surface up to 18" (457mm) above the cooktop (shaded area).
• C. Minimum 1" (25mm) from the rear wall.

Overhead Cabinet Dimensions

• D. Minimum 18" (457mm) vertical distance from the countertop to the bottom of side cabinets within minimum side clearance.
• E. Minimum vertical distance between the countertop and combustible materials above the cooktop must be 30" (762mm).
• F. Minimum spacing between overhead side cabinets must be greater than or equal to the nominal width of the cooktop unit(s).
• G. Maximum 13" (330mm) depth of overhead and side cabinets directly above and within side clearance (See letter B).

Figure 2-1. Installation Specifications.

INSTALLATION DIMENSIONS FOR CT15I

This cooktop is designed for a standard 24" (610 mm) width base cabinet with a 25" (635 mm) deep countertop. Verify clearance of the cooktop with the side walls of the base cabinet below before making the countertop cut-out. There should be at least 6" (152mm) clearance between the top countertop surface and any combustible surface directly below the unit. This includes upper edges of drawers located directly below the unit. If a shelf is installed below the unit, a 1" (25mm) gap at the rear of the cabinet shelf is necessary for proper ventilation. Failure to do so could result in decreased performance or product damage.

NOTES:

• Locate junction box within reach of 48"(1219 mm) conduit, so it is accessible when the cooktop is installed.
• Plastic or other utensils with low melting temperatures should not be located in drawers directly below the unit.

MULTIPLE COOKTOP INSTALLATIONS

If the induction cooktop is to be used with any combination of additional cooktop units or modules with a filler strip, the cut-out width is calculated by adding the corresponding units' cut-out dimensions plus 1-1/4" (32mm) for each additional unit (See Figure 2-2).

NOTES:

• For Model CT15I, the cut-out width should be increased from 13-3/8” (340mm) to 14” (356mm) when installed with multiple units.
• When multiple units are installed side by side, each unit must have its own separate recommended electrical circuit.
• It is recommended that you operate the Wolf induction cooktop with either a Wolf cooktop ventilation hood, downdraft system or Pro ventilation hood. Contact your Wolf dealer for information.

Figure 2-2. Multiple Cooktop Arrangements.

When two or more modules are installed together, an integrated module filler strip (IFILLER/S) is recommended. If a 30" (762mm) downdraft ventilation system is also installed, an integrated module support for downdraft ventilation (ISUPPORT) is also required. Contact your Wolf dealer for information on these accessory components.

Ventilation Options

NOTE: It is recommended that you operate the Wolf induction cooktop with either a Wolf cooktop ventilation hood, downdraft system or Pro ventilation hood. Contact your Wolf dealer for details.

The following is a list of ventilation units that can be used with the induction cooktops:

• Cooktop Wall Hood: 30"(762mm) or 36"(914mm) widths in classic stainless steel.
• Cooktop Island Hood: 42"(1067mm) width in classic stainless steel.
• Downdraft Ventilation System: 30”(762mm), 36”(914mm) or 45”(1143mm) widths, with top cover and control panel in classic, platinum and carbon stainless steel finishes. 45"(1143mm) downdraft available in classic finish only.

NOTE: When installing a ventilation hood, refer to the specific requirements of the hood for the minimum dimension to countertop.

COOKTOP INSTALLATION

Attach the foam strip to the underside of the cooktop frame. Gently lower the cooktop into the cut-out area in the countertop and center. Check that the front edge of the cooktop is parallel to the front edge of the countertop. Check that all required clearances are met.

Attach the brackets to the bottom of the unit, as shown in the illustration below. Install the clamping screws into the bracket and tighten until the screws contact the underside of the countertop. Do not over-tighten the screws (See Figure 2-3).

NOTE: Do not seal the cooktop to the countertop. The cooktop must be removable if service is necessary.

WARNING: IF THE CERAMIC GLASS TOP OF COOKTOP IS BROKEN, TURN OFF POWER TO UNIT. DO NOT OPERATE UNTIL GLASS HAS BEEN REPLACED BY A WOLF AUTHORIZED SERVICE CENTER.
