  Electrical Code ANSI/NFPA No. 70, latest edition.

1.  Providing Adequate Gas Supply

This cooktop is designed to operate at a pressure of 5” of water column with natural gas or 10” of water column with LP, propane 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 with natural or propane gas. When using this cooktop with LP gas, the conversion must be made by a qualified LP installer before attempting to operate the cooktop using that gas.
For correct operation, the pressure of natural gas supplied to the regulator should be 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 must be a maximum of 3 feet in length for easy installation. In Canada, flexible connectors should be single wall metal connectors less than 6 feet in length.

2. Connecting 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 prevent gas leaks, put pipe joint compound on all male (external) pipe threads.

• Install a manual gas line shut-off valve in the gas line in an easily accessed location outside of the Be sure everyone operating the cooktop knows where and how to shut off the gas supply to the cooktop.
• Install a male 1/2” flare union adapter to the 1/2” NPT internal thread at the inlet of the pressure Use a backup wrench on the pressure regulator fitting to prevent damage.
• Install a 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
• Connect a flexible metal connector to the adapter on the Position the cooktop to permit connection at the shut-off valve.

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 for gas leaks using a manometer. If a manometer is not available, turn the gas supply to the cooktop on and use a liquid leak detector at all joints and connections to check for leaks. 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
• The appliance and its individual 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 psi (3.5 kPa).
• The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

.3 .Electrical Connections

Electrical Requirements

This cooktop requires a 120 Volt, 60 Hertz, properly grounded dedicated circuit protected by a 15 A or 20 A circuit breaker or time-delay fuse.
The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, NFPA70 or the Canadian Electric Code, CSA C22.1-02.

Grounding

IMPORTANT: FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.
Preferred Method

Ensure proper ground exists before use.

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.
The customer should have the wall receptacle and circuit checked by a qualified technician to be sure the receptacle is properly grounded.
When connecting this cooktop, it is the personal responsibility and obligation of the customer to have a standard two-prong wall receptacle 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.
A word about Ground Fault Circuit Interrupters – A Ground Fault Circuit Interrupter (GFCI) is not required or recommended for gas range receptacles.

GFCIs 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 GFCIs in kitchen receptacles installed to serve countertop surfaces.
Performance of the cooktop will not be affected if it is operated from a circuit protected by a GFCI, but resetting the circuit can become a nuisance.

• If needed, have the circuit checked by a qualified technician to make sure the receptacle is correctly

DO NOT use an adapter plug because disconnection of the power cord places undue strain on the adapter and causes eventual failure of the adapter ground terminal.
If only a two-prong wall receptacle is available, it must be replaced with a three-prong (grounding) receptacle by a qualified electrician before plugging in the cooktop.
The installation of appliances designed for manufactured (mobile) home installation must 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 with local codes where applicable.
