General Safety Precautions
Information contained in this manual is intended for use by a qualified service
technician. The technician is required to be familiar with proper and safe
procedures
to be followed when repairing electric, gas, and microwave appliances.
All tests and repairs are
to be performed using proper tools and measuring devices
designed
for appliance diagnosis and repair. All component replacements should
bemade using only factory approved replacement parts.
Electrical shock and
injury can result if service or repairs are attempted by an
unqualified individual.
Improper disassembly, assembly or adjustments can
create hazardous
conditions.
Even for askilled technician, arisk of injury or electrical shock exists while
performing service or repairs. Electrical injury can be serious or fatal.
Extreme caution must taken when performing voltage checks on individual
components of an appliance.
NOTE:
Except as necessary to perform a particular step in servicing a
product, the electrical power supply should always be disconnected
when servicing a product.
To avoid possible injury, the appliance must be properly grounded. Never plug
in
or direct wire an appliance unless it is properly grounded in accordance with
all local and national codes. See the installation instructions that originally

extreme caution must be taken.
To avoid possible injury, the appliance must be properly grounded. Never plug
in
or direct wire an appliance unless it is properly grounded in accordance with
all local and national codes. See the installation instructions that originally
accompanied the product for proper grounding procedures.
In
our continuing effort to improve the quality and performance of our cooking products, it
may be necessary to make changes to the appliance without revising this manual.
The model and serial
number can be found on the data plate located on the underside of the
cooktop. The model number identifies features, sizes and engineering changes. The model
number assist the technician in establishing the proper service procedures for the different
variations
of cooking products.

Model/Serial Plate
The Model/Serial plate is located on the
bottom of the cooktop towards the back. For
downdraft models, the model/serial plate is
located on
the side of the plenum under the
cooktop. The model number is very
important to the technician for ordering parts
both in and
out of warranty. Always be sure
to use the complete model number when
ordering parts.
A IMPORTANT
UniqlJe product information for specific
models is found in the
wiring and model specific information
section of this manual.

Wiring Information
A wiring diagram /schematic is supplied
with the unit. It is attached to the underside
of the cooktop. Please return the diagram to
the storage compartment for future use.

Wiring information in this manual was ac-
curate
at the time of manual production.
Wiring information is subject to change at

Electrical Wiring Information
Electrical Wiring Information
The neutral of this unit is grounded to the
frame through the solid copper grounding
wire. If local codes
do not permit grounding
of the neutral, untwist or disconnect the solid
copper
wire and connect the solid copper
wire to ground in accordance with local
codes. Connect
the white neutral to the
service neutral.
Proper Electrical Supply
You must provide an adequate electrical
supply system
as required for your cooktop.
All
wire connections must be in accordance
with local codes and properly insultated.
Check
with local utility for governing
electrical codes and ordinances.
In the
absence of local electrical codes, the National
Electrical Code, NFPA No. 70, governing
eletric range installations
must be followed.
A
copy of the National Electrical Code, NFPA
No. 70, can be obtained
by writing to:
National Fire Protection Association
Batterymarch Park
Quincy, Massachusetts 02269
Athree-wire, single phase, A.C. 120/240
volt
60 cycle electrical system (properly circuit
protected
to meet Local Codes of NFPA No.
70)
must be provided. Unit must be properly
grounded in accordance with local wiring
code. The chart below recommends the
minimum circuit protector and wire size if
the appliance is the only unit on the circuit. If
smaller sizes
of wire are used, the unit
efficiency will be reduced and afire hazard
may be created. It is advisable that the
electrical wiring and hookup be
accomplished
by a competent electrician.

WARNING
ELECTRICAL GROUNDING INTRUCTIONS
THIS APPLIANCE IS EQUIPPED WITH A
THREE PRONG GROUNDING PLUG FOR
PROTECTION AGAINST SHOCK HAZARD
AND SHOULD
BE PLUGGED DIRECTLY
INTO A
PROPERLY GROUNDED
RECEPTACLE. DO NOT CUT
OR REMOVE
THE GROUNDING PRONG FROM THIS
PLUG.
WARNING
THIS APPLIANCE MUST BE
DISCONNECTED FROM ITS ELECTRICAL
SUPPLY AT THE WALL RECEPTACLE
BEFORE SERVICING THE APPLIANCE.
The non-vented units are provided with 1/2"
(1.3 em) flexible cable, 45" (114.3 em)
long
with 6" (15.2 em) wire leads at end, furnished
and installed
by manufacturer (connect to
240/120 volt electrical service). Cable is lo-
cated at
the center rear of the cooktop. Refer
to owner's installation manual if needed.
ProperServiceProcedure
When testing, removing, replacing compo-
nent or components or performing service:
1. Disconnect the appliance from power
source.
2. Note the location of electrical wiring
attachments and disassembly order for
ease in reassembly.
3. Reassemble in the reverse order of re-
moval unless specified otherwise.
4. Ensure that electrical connections are
attached and secure.
5. Ensure that wiring is secured away from
sharp edges and moving parts.
6. Do not bypass or disconnect any part or
device designed into the appliance.

7. Ensure that ground wiring is connected
and secure.
8. Ensure that access panels, covers, tape,
and seals are installed.
Ignition/Spark Module
The ignitor wires are color coded to match
the input wiring color. If the polarity gets
reversed (the
power cord is indexed at both
ends, reverse polarity can
only occur at the
outlet). The ignitor will continue to spark
after
burner lights. If the ignitor module is
mis-wired,
the same thing will occur.
Wiring, polarity, and grounding are critical
to
proper operation. Connections at the
module and at the ignitor should be snug. A
loose connection is added resistance
to the
circuit.
Spark Module
Gas Components
NOTE: Before replacing any component,
check the following:
• Be sure 120 VAC power is supplied to
unit.
• Be sure correct gas fuel, at correct pres-
sure, is supplied
to manifold inlet. The gas
supply line is open and air has been bled
from gas lines.
• When an electrical component is non-
operative, check
to be sure the correct
electrical leads are securely attached
to it.
Wire leads are color-coded and identified
with stampings.
• When an electrical malfunction cannot be
readily located, use a continuity tester
to
trace circuit. Check wire harness for
separated wires, splices, etc.
• If ducting and wall cap are not connected
to blower vent, be sure deflected drafts are
not causing ignition failure or other burner
flame disturbance.
Provides 14,000
to 16,000 VDC to ignitors. Do Gas Leaks
not check output.
Check for 120 VAC between Land N. Ensure
tight connections at 1, 2, and at ignitors.
Ensure sure
proper product grounding.
16010242
CAUTION:
Never check for gas leaks with an open
flame. Check for leaks using a soap and
water solution.
