Installation Procedure
WARNING: To avoid electrical shock hazard, before installing the
cooktop, switch power off at the service panel and lock the panel to
prevent the power from being switched on accidentally.
Seal the Cooktop with Foam Tape
Apply the foam tape packaged with the cooktop to underside of the cooktop along
the perimeter before installing.
Prepare the Countertop Cut out the countertop per the dimensions shown in section Countertop Cutout
Dimensions above. For solid surface material installations such as Surell™ and
Corian®, consult with solid surface manufacturer. Apply heat reflective tape such
as Scotch Aluminum Foil Tape #425 or #427 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.

tighten screws to rough-in box. Insert adjusting screw into clamp and secure cooktop to countertop.
For solid surface material installations: Insert a wooden block between the end of
the screw and the bottom of the countertop. Do not overtighten adjusting screw.
Trim excess aluminum tape around cooktop flange.

Connect Gas Supply The gas inlet to the unit is located at the right rear of rough-in box. After installing
a gas shut-off valve in an easily accessible location under the unit, install the pressure regulator (supplied) to manifold pipe using Teflon tape on threads of manifold
pipe. To prevent possible damage to the gas pressure regulator, install it after the
rough-in box is in its permanent position.

Secure regulator to cooktop gas inlet using approved Teflon tape. Turn to hand
tighten plus 1/4 turn, not exceeding 1 turn for alignment.
Check supply line connections for leaks using a soap solution. Do not use a flame
of any sort.
1) Turn on gas.
2. Apply a non-corrosive leak detection fluid to all joints and fittings in the gas
connection between the shut-off valve and the range. Include gas fittings and
joints in the range if connections may have been disturbed during installation.
Bubbles appearing around fittings and connections indicate a leak.
3. If a leak appears, turn off supply line gas shut-off valve and tighten connections.
4. Retest for leaks by turning on the supply line gas shut-off valve. When leak check is complete (no bubbles appear), test is complete.
5. Wipe off all detection fluid residue.

Important Notes for Gas Connection:
e
• The appliance and its individual gas shutoff valve must be disconnected from
the gas supply piping system during any pressure testing of that system at
test pressures in excess of 1/2 psig (3.5kPa).
• The appliance must be isolated from the gas supply piping system by closing
its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5kPa).
Connect Electrical Supply
Before connecting 5-foot (1.5 m) supply cord to wall receptacle, make certain that
gas shutoff valve and all burner controls are in OFF position.
Final Check After electrical connection is complete, place each burner cap in correct sized
notched position and check operation of electric igniters. Check flame characteristics. Flame should be blue with no yellow tip.
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow,
verify that the regulator is set for the correct fuel. After adjustment, retest.
Some yellow streaking is normal during the initial start-up. Allow unit to operat
4-5 minutes and re-evaluate before making adjustments.
Service
Before Calling Service
Figure 7: Checking Flame Characteristics
If the elements do not heat or if the indicator “on” light does not glow, check the
power source to see if a fuse has blown or if the circuit breaker has tripped.
Refer to the Warranty in the Use and Care Manual. See Use and Care manual for
troubleshooting information.
