Safety Instructions

Installation of the range (cont.).

Provide Adequate Gas Supply

Your range is designed to operate at a pressure of 4 ″ of water column on natural gas or, if designed for LP gas (propane or butane), 10 ″ of water column.

Operating Instructions

Make sure you are supplying your range with the type of gas for which it is designed.

This range is convertible for use on natural or propane gas. If you decide to use this range on LP gas, conversion must be made by a qualified LP installer before attempting to operate the range on that gas.

For proper operation, the pressure of natural gas supplied to the regulator must be between 4″ and 13″ of water column.

For LP gas, the pressure supplied must be between 10″ and 13″ of water column.

When checking for proper operation of the regulator, the inlet pressure must be at least 1″ greater than the operating (manifold) pressure as given above.

The pressure regulator located at the inlet of the range 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 range to the gas supply line should have an I.D. of 1/2″ and be 5 feet in length for ease of installation. In Canada, flexible connectors must be single wall metal connectors no longer than

6 feet in length.

Instructions

Connect the Range to Gas

Shut off the main gas supply valve before disconnecting the old range 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.

Troubleshooting Tips Installation

Customer Service

Because hard piping restricts movement of the range, the use of an A.G.A.-certified flexible metal appliance connector is recommended unless local codes require a hard-piped connection.

Never use an old connector when installing a new range. If the hard piping method is used, you must carefully align the pipe; the range cannot be moved after the connection is made.

To prevent gas leaks, put pipe joint compound on, or wrap pipe thread tape with Teflon* around, 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 range. Make sure everyone operating the range knows where and how to shut off the gas supply to the range.

Install male 1/2″ flare union adapter to the 1/2″ NPT internal thread elbow at inlet of regulator. On models equipped with standard twin burners, install the male pipe thread end of the 1/2″ flare union adapter to the 1/2″ NPT internal thread at inlet of pressure regulator. Use a backup wrench on the regulator fitting to avoid damage.

When installing the range from the front, remove the 90° elbow for easier installation.

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.

Connect flexible metal appliance connector to the adapter on the range. Position range to permit connection at the shut-off valve.

When all connections have been made, make sure all range controls are in the off position and turn on the main gas supply valve. Use a liquid leak detector at all joints and connections to check for leaks in the system.

CAUTION: DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

When using test pressures greater than 1/2 psig to pressure test the gas supply system of the residence, disconnect the range and individual shut-off valve from the gas supply piping. When using test pressures of 1/2 psig or less to test the gas supply system, simply isolate the range from the gas supply system by closing the individual shut-off valve.
