•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 circumstances, 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.

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	Apply the foam tape packaged with the cooktop to underside of the cooktop along
Foam Tape	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 roughin 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 cook-
		top 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 pres-
		sure 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 sup-
		ply 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 characteris-
		tics. Flame should be blue with no yellow tip.

Yellow Flames:

Further adjustment is required.

Yellow Tips on Outer Cones:

Before Calling Service

Product Data Plate

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-

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.

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.
