Cooktop” on page 5 for further details.
Ventilation Recommendations
We strongly recommend the installation of a ventilation
hood above this appliance. The hood must be installed
according to instructions furnished with the hood.
Installation Procedure
WARNING:
To avoid electrical shock hazard, before
installing the cooktop, switch power off at the
service panel to prevent the power from being
switched on accidentally.
Prepare the Countertop
Cut out the countertop per the dimensions shown in
“Cabinet Requirements” on page 3.
Some solid surface materials, such as Surell™ and
Corian®, require different cutting methods. Consult with the
solid surface manufacturer for the correct cutting method
needed. Apply heat reflective tape such as Scotch
Aluminum Foil Tape #425 or #427 (not included) around
the cutout so that it folds over on the top and sides. Do not
wrap the tape underneath the cooktop. Be sure the tape
extends beyond the outermost flange of the cooktop. All
corners should be covered with tape.
Seal the Cooktop with Foam Tape
Apply the self adhesive foam tape in one continuous
rectangle directly to the counter around the perimeter of the
cutout as shown by the dotted line in Figure 4: “Counter
