• Installation must conform with local codes or, in the absence of local codes
with the National Fuel Gas Code, ANSI Z223.1.
• The appliance must be electrically grounded in accordance with local codes
or, in the absence of local codes, with the National Electrical Code ANSI/
NFPA 70, latest edition. (in Canada, installation must be in accordance with
the CAN 1-B149.1 and .2 Installation Codes for Gas Burning Appliances and/
or local codes.)
• This appliance has been tested in accordance with ANS Z21.1, Standard for

Interim Reqt #58 Domestic Gas Cooktops (CANADA).
• Additional requirements and standards may apply in specific installations.
Equipment and Usage Safety Requirements
• The cooktop must be used in conjunction with a suitable ventilation system.
• 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. tf
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.

Gas Supply Pressure
•Natural Gas - 6 inches water column (14.9 Millibars) minimum.
• Propane Gas -11 inches water column (27.4 Millibars) minimum.
The maximum supply pressure to this appliance shall not exceed 14.0 inches
water column (34.9Millibars).
Gas Appliance Safety
WARNING: If the information in this manual is not
followed exactly, afire 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-

If parts are missing or damaged, call the number or write to the address listed
inside the back cover.
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.

NOTE: All measurements given have to be precisely followed. If nonstandard
cabinets are used, make sure they are installed with minimum dimensions shown
in fig. 1 and fig. 2.
Plan the installation of the unit so that the power cord, gas shut-off valve and gas
pressure regulator are accessible from the front of cabinet. If a drawer is installed
directly under the cooktop, its depth (front to back) should be no greater than 15"
(38cm).

Installation Procedure
1) Seal the Cooktop with
Foam Tape
2) Prepare the Countertop
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 TM 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.

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
5) Connect Gas Supply
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.
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.

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 pro-
cedure in Figure 6.)

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 connec-
tions.
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

6) Connect Electrical Supply
7) Final Check
• 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).
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 characteris-
tics. 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
Product Data Plate
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.
