Provide Adequate Gas Supply; Connect The Cooktop To Gas - LG LSCG306ST Service Manual

INSTALLATION INSTRUCTIONS

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
5
an I.D. of / " and can be 3 feet in length easily for installation. In Canada, flexible connectors
8
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 protect gas leaks, put pipe joint compound on, all male -external- pipe threads.
❶ 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.
