Gas Appliance Safety
		WARNING: If the information in this manual is not
		followed exactly, a fire or explosion may result caus-
		ing property damage, personal injury or death.
		Do not store or use combustible materials, gasoline or other flam-
		mable vapors and liquids in the vicinity of this or any other appli-
		ance.
		• WHAT TO DO IF YOU SMELL GAS:

Propane Gas Installation (NGT Models only)

•Do not try to light any appliance. •Do not touch any electrical switch.

•Do not use any phone in your building.

•Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

Installation and service must be performed by a qualified installer, authorized service agency or the gas supplier.

NOTE: NGP models cannot be converted for propane use.

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 from the factory for use with natural gas. For use with LP, a conversion kit is required and must be purchased separately. Contact BSH or your retailer to obtain kit # NEZ1065. A qualified technician or installer must do the conversion.

Preparation

Electrical Requirements	This appliances requires a 60 Hz, 15 Amp, 120 VAC connection. Plan the installa-
	tion so that the power connection is accessible from the front of the cabinet.
Gas Requirements	Supply Pressure:

English 3

	• Natural Gas - 6 inches water column (14.9 Millibars) minimum.
	• Propane Gas -11 inches water column (27.4 Millibars) minimum.
	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
	from the factory for use with natural gas. For use with LP conversion kit – Model
	NEZ1065, must be purchased separately. A qualified technician or installer must
	do the conversion.
	Note: NGP model cooktops cannot be converted for LP use.
Cabinet Requirements	Dimension requirements in Figs. 1 & 2 are for combustible surfaces. When the
	surface is protected by a material listed by UL as a Floor Protector and Wall
	Shield covered with not less than No. 28 MSG sheet metal 0.015 inch (0.38mm)
	stainless steel, 0.024 inch (0.6mm) aluminum or copper, it is considered noncom-
	bustible and some dimensions may be reduced. For a noncombustible surface
	over the cooktop, the minimum clearance is 24" (61cm) rather than 30" (76cm) .
	• Instructions are based on standard American cabinets 36" high (91cm) x 24"
	deep (61cm) with a 25" (63cm) countertop.
	• Provide approximately a 10 square inch opening (65cm2) in the toe kick area
	or other cabinet area for adequate air inlet to the cabinet.

Installation

Procedure

Seal the Cooktop with Foam Tape

Prepare the Countertop

Attach Brackets to the Cooktop

Install the Cooktop

English 6

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.

Apply the foam tape packaged with the cooktop to underside of the cooktop along the perimeter before installing.

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.

Figure 4: Attaching Hold-Down Brackets

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.

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.

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.

Final Check

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).

•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).

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.

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.

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.
