• Before plugging in an electrical cord, be sure all controls are in OFF position.
Power Requirements and Electrical Grounding Instructions
• Power Supply: 120 Volts, 15 Ampere, 60 Hz. This appliance is factory
equipped with a 5-foot power supply cord with a 3-prong grounding plug (with
polarized parallel blades).
• To prevent electrical shock, the third ground prong should not under any cir-
cumstances, be cut or removed. It must be plugged into a matching grounding
type receptacle, connected to a correctly polarized 120-volt circuit.
• A separate circuit is recommended which is in compliance with the NEC. If
there is any doubt as to whether the wall receptacle is properly grounded, the
customer should have it checked by a qualified electrician.
Gas Requirements
• A manual valve must be installed in an accessible location in the gas line
external to the appliance for the purpose of turning on and shutting off the gas
to the appliance.
• Leak testing of the appliance shall be conducted according to manufacturer’s
instructions.

The propane gas tank must be equipped with its own high pressure regulator in
addition to the pressure regulator supplied with this unit. The cooktop is shipped

Leak testing of the appliance shall be conducted according to manufacturerís
instructions.
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.
1) Seal the Cooktop with Foam Tape
Apply the foam tape packaged with the cooktop to underside of the cooktop along
the perimeter before installing.
2) 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.

Section "A - A"
3) Attach Brackets to the Cooktop Attach clamps of the hold-down brackets packaged with the cooktop to the rough-
in box. Use the washer and screws provided.
Figure 4 - Attaching Hold-Down Brackets
4) Install the Cooktop Insert cooktop into the cutout. Adjust hold-down brackets to desired position and
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.
5) 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.

for 30” models - 12-5/8“ (320.8 mm)
for 36” models - 15-1/2“ ( 394 mm)
CAUTION: Do not attempt any adjustment of the pressure regulator,
except conversion to propane.
Connect the gas supply line to the unit pressure regulator using a 1/2" flex gas line
connector between wall shut-off valve and pressure regulator (see complete procedure in Figure 6.)
Figure 6 - Gas and Electrical Location
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:
• 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).
English 6
• 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).
6) 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.
7) 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 oper-
Before Calling Service 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.
Product Data Plate The data plate shows the model and serial number of your cooktop. It is located in
the center front area of the rough-in box, underneath the cooktop.
Keep your invoice or escrow papers for warranty validation if service is needed.
