The Wolf Induction Cooktops require a separate, grounded three-wire service with their own circuit breaker. These
appliances must be installed in accordance with National Electrical Codes, as well as all state, municipal and local
codes. The correct voltage, frequency and amperage must be supplied to the appliance from a dedicated, grounded
circuit which is protected by a properly sized circuit breaker or time delay fuse. The proper voltage, frequency and
amperage ratings are listed on the product rating plate. The cooktops are provided with a 48” (1219 mm) conduit
consisting of two insulated hot lead conductors (copper) and one insulated ground conductor (copper).
• THIS APPLIANCE MUST BE PROPERLY GROUNDED AT ALL TIMES WHEN ELECTRICAL POWER IS
APPLIED.
• DO NOT GROUND APPLIANCE WITH NEUTRAL (WHITE) HOUSE SUPPLY WIRE. A SEPARATE GROUND
WIRE MUST BE UTILIZED.
• IF ALUMINUM HOUSE SUPPLY WIRING IS UTILIZED, SPLICE APPLIANCE COPPER WIRE TO ALUMINUM
HOUSE WIRING USING SPECIAL CONNECTORS DESIGNED AND CERTIFIED FOR JOINING COPPER AND
ALUMINUM. FOLLOW THE CONNECTOR MANUFACTURES RECOMMENDED PROCEDURE CAREFULLY.
IMPROPER CONNECTION CAN RESULT IN A FIRE HAZARD.
•TO ELIMINATE RISK OF BURNS OR FIRE BY REACHING OVER HEATED SURFACE UNITS, CABINET STOR-
AGE 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 HORIZONTAL-
LY A MINIMUM OF 5''(127mm) BEYOND BOTTOM OF THE CABINETS.

• FAILURE TO LOCATE THE COOKTOP WITHOUT THE PROPER CLEARANCES WILL RESULT IN A FIRE HAZ-
ARD.
•TO ELIMINATE RISK OF BURNS OR FIRE BY REACHING OVER HEATED SURFACE UNITS, CABINET STOR-
AGE 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 HORIZONTAL-
LY A MINIMUM OF 5''(127mm) BEYOND BOTTOM OF THE CABINETS.

or greater than cooktop width.
B. Minimum 1” (25mm) wide clearance from the cook-
top side edge to any combustible surface up to 18”
(457mm) above the cooktop (noted by shaded
area).
C. Minimum 1” (25mm) from rear wall.

INSTALLATION DIMENSIONS FOR CT15I
(Refer to Illustrations to the right & below):
This cooktop is designed to fit a standard 24” (610 mm)
width base cabinet with a 25” (635 mm) deep counter
top. Before making the counter top cut-out, verify that
the cooktop will clear the side walls of the base cabinet
below. There should be at least 6” (152mm) clearance
between the top counter top surface and any com-
bustible surface directly below the unit. This includes
upper edges of drawers located directly below unit. If a
shelf is installed below the unit, a 1” (25mm) gap at the
rear of the cabinet shelf is necessary to allow 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 unit.
