2. Screw Positions

NOTE

• The retainer brackets MUST be installed to meet local codes or, in their absence, the National Electrical Code ANSI/NFPA No. 70, latest edition.

 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.

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.

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. Install a male 1/2” flare union adapter to the 1/2” NPT internal thread at the inlet of the pressure regulator. Use a backup wrench on the pressure regulator fitting to prevent damage. Make sure that the access cap on the gas regulator is facing the front of the cabinet and is easily accessible through the cabinet doors.
3. 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 turning.
4. Connect a flexible metal connector to the adapter on the cooktop. Position the 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 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 LEAKS.
• 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).
