Read these instructions completely and carefully.

Connect the Range to Gas

The house piping and connector used to connect the range to the main gas supply must be clean, free of metal shavings, rust, dirt or liquids (oil or water). Contaminants in the supply lines can work their way into the range manifold and cause failure of gas valves or controls and clog burners or pilot orifices.

If the range is to be connected to house piping with flexible or semi-rigid metal appliance connector, connector nuts MUST NOT be connected directly to pipe threads.

The appliance connector must be installed by using the proper flare union adapters with the connector. Cutoff valve, appliance connector and adapters are not supplied with the range. Because hard piping restricts movement of the range, the use of a CSA International-certified flexible metal appliance connector is recommended unless local codes require a hard-piped connection. In Canada, flexible connectors must be single wall metal connectors no longer than 6 feet in length.

Install a manual shutoff valve in the gas line in an easily accessible location outside of the range. Be sure you know how and where to shut off the gas supply to the range.

Check for leaks. After connecting the range to gas, check the system for leaks with a liquid leak detector at all joints and connections.

Tighten all connections as necessary to prevent gas leakage in the range or supply line.

CAUTION: Do not use a flame to check for gas leaks.

Check alignment of valves after connecting the range to the gas supply to be sure the manifold pipe has not been moved. A misalignment could cause the valve knob stem to rub on the control panel, resulting in a gas leak at the valve.

Disconnect the range and its individual shut-off valve from the gas supply piping system during any pressure testing of the system at test pressures greater than 1/2 psig.

Isolate the range from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig.

Checking Manifold Gas Pressure

If it should be necessary to check the manifold gas pressure, connect manometer (water gauge) or other pressure device to the top burner orifice farthest from the manifold inlet and turn burner valve on.

For an accurate pressure check, have at least

2 other top burners burning. Be sure the gas supply inlet pressure is at least one inch above specified range manifold pressure.

The gas supply pressure should never be over 14 inches W.C. When properly adjusted for natural gas, the W.C. pressure is 4 inches; for LP gas, the W.C. pressure is 10 inches. The range was factory adjusted for use with natural gas. It may have been converted for use with LP gas in step 3.
