Location Requirements

IMPORTANT : Observe all governing codes and ordinances. When installing the cooktop, use the minimum dimensions given.

  • To eliminate the risk of burns or fire by reaching over the heated surface units, cabinet storage space located above the surface units should be avoided. If cabinet storage is to
    be provided, the risk can be reduced by installing a range hood that projects horizontally a minimum of 5″ (12.7 cm) beyond the bottom of the cabinets.

  • The cooktop must be a specified cooktop that is approved to be installed either alone or over an under-counter built-in oven. Check the cooktop base for an approved installation label. If you do not find this label, contact your dealer to confirm that your cooktop is approved.

  • The cooktop must be installed on a level countertop.

  • Ovens approved for this type of installation will have an approval label located on the top of the oven. If you do not find this label, contact your dealer to confirm that your oven is approved. Refer to oven manufacturer’s Installation Instructions for approval for built-in undercounter use and proper cutout dimensions.

  • The cooktop should be installed away from strong draft areas, such as windows, doors, fans, or strong heating vents. The cooktop should be located for convenient use in the kitchen.

  • Use the countertop opening dimensions that are given with these Installation Instructions. Given dimensions are minimum clearances and provide 0″ (0 cm) clearance.

  • A grounded electrical supply is required. See “Electrical Requirements” section.

IMPORTANT: To avoid damage, check with your builder or cabinet supplier to make sure that the materials used will not
discolor, delaminate or sustain other damage.

Electrical Requirements

WARNING



Electrical Shock Hazard
Disconnect power before servicing.
Use 8 gauge copper wire.
Electrically ground cooktop.
Failure to follow these instructions can result in death, fire, or electrical shock.

If codes permit and a separate ground wire is used, it is recommended that a qualified electrical installer determine that the ground path and wire gauge are in accordance with local codes.
Check with a qualified electrical installer if you are not sure the cooktop is properly grounded.
Make sure that the electrical connection and wire size are adequate and in conformance with the National Electrical Code, ANSI/NFPA 70-latest edition or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No. O-M91-latest edition, and all local codes and ordinances.

A copy of the above code standards can be obtained from:

Before You Make the Electrical Connection:
To properly install your cooktop, you must determine the type of electrical connection you will be using and follow the instructions provided for it here.

  • A 3-wire or 4-wire, single-phase, 120/240 volt, 60-Hz., AC-only electrical supply is required on a separate, 40-amp circuit fused on both sides of the line. The model/serial number rating plate is located on the metal cabinet underneath the cooktop. See the following illustration.

ELECTRIC COOKTOP - Model-serial number plate

  • The cooktop is rated 120/240 volt. Some models have a neutral (white) wire.
  • The cooktop should be connected directly to the junction box through flexible, armored or nonmetallic sheathed, copper cable. The flexible, armored cable extending from the fuse box or circuit breaker box should be connected directly to the junction box.
  • Locate the junction box to allow as much slack as possible between the junction box and the cooktop so that the cooktop can be moved if servicing becomes necessary in the future.
  • Do not cut the conduit. Use the length of a conduit provided.
  • A UL-listed or CSA-approved conduit connector must be provided at each end of the power supply cable (at the cooktop and at the junction box). A listed conduit connector is already provided at the cooktop.
  • If the house has aluminum wiring, follow the procedure below:
    1.Connect a section of solid copper wire to the pigtail leads.
    2.Connect the aluminum wiring to the added section of the copper wire using special connectors and/or tools designed and UL listed for joining copper to aluminum. Follow the electrical connector manufacturer’s recommended procedure. Aluminum/copper connection must conform with local codes and industry accepted wiring practices.

INSTALLATION INSTRUCTIONS

Prepare Cooktop for Installation

WARNING

Excessive Weight Hazard

Use two or more people to move and install the cooktop.

Failure to do so can result in back or another injury.

Decide on the final location for the cooktop. Avoid drilling into or severing existing wiring during installation.

  1. Using 2 or more people, place the cooktop upside down on a covered surface using the foam end posts from the packaging. Make sure that the knobs are not resting on the foam.
  2. Remove foam strip roll from the package containing literature. The roll contains four ¼” (0.64 cm) strips of foam. Remove one strip at a time and apply foam strip adhesive-side down around the bottom of the cooktop glass.
    NOTE : The foam strip helps avoid damage to the underside of the cooktop glass from debris and helps the cooktop sit flat on uneven counters.
