DIMENSIONS AND CLEARANCES

Provide enough clearances between the cooktop and adjacent combustible surfaces. These dimensions must be met for safe use of your cooktop.
The location of the electrical outlet and pipe opening may be adjusted to meet specific requirements.
The cooktop may be placed with 2 3/4” clearance to the back wall.

1. MAINTAIN THE FOLLOWING MINIMUM CLEARANCE DIMENSIONS
2. COOKTOP AND CUTOUT DIMENSIONS
3. RECOMMENDED GAS SUPPLY LOCATION FROM BACKWALL
4. MAKE SURE WALL COVERINGS, COUNTERTOP AND CABINETS AROUND COOKTOP CAN WITHSTAND HEAT(UP TO 200℉) GENERATED BY COOKTOP To ensure accuracy, it is best to make a template when cutting the opening in the counter

INSTALLING THE COOKTOP UNIT

1. LOCATE ELECTRICAL OUTLET AND GAS SHUT-OFF VALVE BENEATH CABINET Install a manual shut-off valve in the gas line in an easily accessible location outside the cooktop. Be sure you know how and where to shut off the gas supply to the cooktop. Install the electrical outlet 12˝ below the countertop.

2. INSERT COOKTOP INTO CUTOUT
   Insert the cooktop centered into the cutout opening. Be sure the front edge of the countertop is parallel to the cooktop. Make final check that all required clearances are met.

3. LOCATE RETAINER BRACKETS
   Remove the retainer brackets from the literature package.

4. INSTALL THE RETAINER BRACKETS
   Install the retainer brackets to the bottom of the cooktop unit. then snug the bolts against the bottom of the countertop as shown

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

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, 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 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 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 can be 3 feet max. in length for easy installation. In Canada, flexible connectors should be single wall metal connectors less than 6 feet in length.

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 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 male 1/2” flare union adapter to the 1/2” NPT internal thread at inlet of pressure regulator. Use a backup wrench on the pressure regulator fitting to prevent damage.
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 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 by using manometer.
   If a manometer is not available, turn the gas supply on 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.
Disconnect the cooktop and its individual shut-off valve from the gas supply piping system during any pressure testing of that system at test pressures more than 1/2 psig(3.5kPa).
Isolate the cooktop from the gas supply piping system by closing its individual shut-off valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psig(3.5kPa)
