INSTALLATION INSTRUCTIONS
1. PROVIDE ADEQUATE GAS SUPPLY
This cooktop is designed to operate at a pressure
of 5” of water column on natural gas or 10” of water
column on LP, propan or butane gas.
Make sure you are supplying your cooktop with the
type of gas for which it is designed.
This cooktop is convertible for use on natural or
propane gas. When using this cooktop on LP gas,
conversion must be made by a qualified LP installer
before attempting to operate the cooktop on that
gas.
For correct operation, the pressure of natural gas
supplied to the regulator should between 5” and
13” of water column.
For LP gas, the pressure supplied must be between
10” and 13” of water column.
When checking for correct operation of the regulator,
the inlet pressure must be at least 1” more than the
operating -manifold- pressure as given above.
The pressure regulator located at the inlet of the
cooktop manifold must remain in the supply line
regardless of whether natural or LP gas is being used.
A flexible metal appliance connector used to connect
the cooktop to the gas supply line must have an
I.D. of 5/8” and can be 3 feet in length easily for
installation. In Canada, flexible connectors should
be single wall metal connectors less than 6 feet
in length.
2. CONNECT THE COOKTOP TO GAS
Shut off the main gas supply valve before
removing the old cooktop and leave it off until the
new hook-up has been completed. Don’t forget to
relight the pilot on other gas appliances when you
turn the gas back on.
Because hard piping restricts movement of the
cooktop, the use of a CSA International-certified
flexible metal appliance connector is recommended
unless local codes require a hard-piped connection.
Never reuse an old connector when installing a new
cooktop. If the hard piping method is used, you must
carefully align the pipe; the cooktop cannot be moved
after the connection is made.
To protect gas leaks, put pipe joint compound on,
all male -external- pipe threads.
1 Install a manual gas line shut-off valve in the gas
line in an easily accessed location outside of the
cooktop. Be sure everyone operating the
cooktop knows where and how to shut off the
gas supply to the cooktop.
2
3 Install male 1/2” or 3/4” flare union adapter to the
NPT internal thread of the manual shut-off valve,
taking care to back-up the shut-off valve to keep
it from turning.
4 Connect flexible metal connector to the adapter
on the cooktop. Position cooktop to permit
connection at the shut-off valve.
5 When all connections have been made, be
sure all cooktop controls are in the off position
and turn on the main gas supply valve.
Check gas leaks by using manometer.
If a manometer is not available, turn the gas supply
on to the cooktop and use a liquid leak detector
at all joints and connections to check for leak.
Tighten all connections if necessary to prevent
gas leakage in the cooktop or supply line.
WARNING!
DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

3. ELECTRICAL CONNECTIONS
ELECTRICAL REQUIREMENTS
120 Volt, 60 Hertz, properly grounded dedicated
circuit protected by a 15 A or 20 A circuit
breaker or time delay fuse.
The power cord of this appliance should be equipped
with a three-prong (grounding) plug which mates with
a standard three-prong grounding wall receptacle to
reduce the possibility of electric shock hazard from
this appliance.
GROUNDING
The customer should have the wall receptacle and
circuit checked by a qualified technician to be sure
the receptacle is properly grounded.
IMPORTANT: FOR PERSONAL SAFETY,
THIS APPLIANCE MUST BE PROPERLY
GROUNDED.
PREFERRED
METHOD
When connecting the cord of this cooktop to a
standard two-prong wall receptacle, it is the
personal responsibility and obligation of the customer
to have it replaced with a properly grounded
three-prong wall receptacle.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR
REMOVE THE THIRD (GROUND) PRONG FROM
THE POWER CORD.
Ensure proper ground
exists before use
A word about Ground Fault Circuit Interrupters –
Ground Fault Circuit Interrupters are not required or
recommended for gas range receptacles.
Ground Fault Circuit Interrupters are devices that
sense leakage of current in a circuit and
automatically switch off power when a threshold
leakage level is detected.
These devices must be manually reset by the
customer.
The National Electrical Code requires the use of
Ground Fault Circuit Interrupters in kitchen
receptacles installed to serve countertop surfaces.
Performance of the cooktop will not be affected if
it is operated from a Ground Fault Circuit Interrupters
protected circuit but occasional nuisance can occur.

INSTALLATION INSTRUCTIONS
3. ELECTRICAL CONNECTIONS (continued)
CAUTION
The customer should have the circuit checked by
a qualified technician to make sure the receptacle
is correctly grounded.
DO NOT use an adapter plug because disconnecting of
the power cord places undue strain on the adapter
and causes eventual failure of the adapter ground
terminal.
The customer must have the two-prong wall
receptacle replaced with a three-prong (grounding)
receptacle by a qualified technician before using this
cooktop.
4. SEAL THE OPENINGS
Seal any openings in the wall behind the cooktop
and in the floor of the cabinet when hookups
are completed.
10
The installation of appliances designed for mobile
home installation should conform with the Manufactured
Home Construction and Safety Standard, Title 24
CFR, Part 3280 (formerly the Federal Standard for
Mobile Home Construction and Safety, Title 24, HUD,
Part 280) or, when such standard is not applicable,
the Standard for Manufactured Home Installations,
latest edition (Manufactured Home Sites,
Communities and Set-Ups), ANSI A225.1, latest
edition, or with local codes. In Canada, mobile home
installation must comply with the current
CAN/CSA Z240/MH Mobile Home Installation Code.

5. ASSEMBLE THE SURFACE BURNERS
Make sure the hole in the burner head is positioned
over the electrode.
CAUTION
DO NOT operate the burners without all parts in
place.

6. CHECK IGNITION OF SURFACE BURNERS
Operation of all cooktop burners should be checked
after the COOKTOP and gas supply lines have been
carefully checked for leaks.
ELECTRIC IGNITION
Select a top burner knob, push down and then turn
counterclockwise to the “LITE” position.
You can hear a clicking sound indicating proper
operation of the spark module.
Once the air has been purged from the supply lines,
burner should ignite within 4 seconds.
After burner ignites, rotate knob out of the “LITE”
position. Try each burner in succession until all
burners have been checked.
QUALITY OF FLAMES
The combustion quality of burner flames needs to be
confirmed visually.
A Yellow flames — Call for service
B Yellow tips on outer cones
— It is normal for LP gas
C Soft blue flames
— It is normal for natural gas
If burner flames look like A , call for service.
B or C is normal burner flames, depending on the
type of gas you use.
With LP gas, some yellow tipping on outer cones is
normal.
