CABINET PREPARATION AND
CLEARANCES
C
CAUTION
To eliminate the risk of burns or fire by reaching
over 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 in. (127
mm) beyond the bottom of the cabinets. See C,
Page 2.
This unit is designed for installation in the counter top
with zero clearance to adjacent walls and projecting
surfaces constructed of combustible materials. A 30inch minimum clearance is required between the top
of the cooktop and the bottom of an unprotected
cabinet. A 24-inch minimum distance is necessary when
the bottom of the wood or metal cabinet is protected
by not less than 1/4 inch of a flame retardant material
covered with not less than No. 28 MSG sheet steel,
0.015-inch (0.4 mm) thick stainless steel, 0.024-inch
(0.6 mm) aluminum, or 0.020-inch (0.5 mm) thick
copper. Flame retardant materials bear the mark:
UNDERWRITERS LABORATORIES INC.
CLASSIFIED
MINERAL AND FIBER BOARDS
SURFACE BURNING CHARACTERISTICS
Followed by the flame spread and smoke ratings, these
designations are shown as “FHC (Flame Spread)/
(Smoke Developed).” Materials with “O” flame spread
ratings are flame retardant. Local codes may allow other
flame spread ratings.
The minimum horizontal clearance from the sides and
back edge of the cooktop to the adjacent vertical
combustible walls is zero inches.
COUNTERTOP CUTOUT
DIMENSIONS
The cutout dimensions depend upon whether the
installation is for replacement, new construction, or
installation in a solid surface countertop material, such
as Surel™, Corian
cutouts, use of heat reflective tape and rounded
corners. Drawings G and H provide some guidelines
only (see Page 4 and 5). Always consult the countertop
manufacturer for specific installation instructions.

Seal with foam tape
A foam tape is provided to seal the cooktop edges to
the countertop (see page 4). Turn cooktop upside down
and apply tape approximately 1/16” from the glass
edges. Use tape around the entire glass perimeter cut
off excess where tape ends butt.
Secure Cooktop to countertop

Solid Surface Countertops H
Always consult the countertop
manufacturer for specific instructions.
Countertops made from natural (i.e. granite and
marble) or SOLID SURFACE MATERIALS, such as
Surell™ and Corian
preparation and installation procedures. Follow the
guidelines below and on pages 2-4 for preparing the
cutout.
Install the cooktop as follows:
1. Round the cutout corners according to
instructions from the countertop manufacturer.
2. Apply heat reflective tape (such as Scotch
Aluminum Foil Tape #425 or #427) around the
cutout so that it folds over the top and side
surfaces. Be sure the tape extends beyond the
outermost flange of the cooktop. All corners
should also be covered with tape.

, require special cutout
ELECTRICAL CONNECTION
1. Attach flexible conduit to the junction box.
2. Connect the cooktop lead wires to the junction
box supply wires in proper phase:
For all models, connect black (L1) to
black, red (L
2) to red, white wire to
neutral and green wire to ground.
NOTE: If the cooktop is installed and connected as
specified above, it will be completely grounded in
compliance with the National Electrical Code.
3. Remove everything from the cooktop surface and
®
apply Cooktop Cleaning Creme (packaged with
cooktop) as directed in Use & Care Manual, Page
9.
4. Turn on power supply.
3. Attach brackets to the burner box using washers
and screws provided. Use a wooden block
underneath the countertop before tightening the
bracket screws.
4. Center cooktop in the cutout to ensure adequate
clearance between the burner box and countertop
edge. (A light pencil mark along the center of front
edge and side edge of cooktop and counter will
aid in the positioning of the cooktop in the center.)
5. Trim excess aluminum tape from along the frame
edges. BE CAREFUL not to scratch the countertop.
5. Test operation.
NOTE: Your cooktop surface needs to be cleaned
daily. Refer to the Use and Care section before using
it for the first time.
