Natural Gas Grills - Connecting to Natural Gas

(for specially equipped natural gas grills only)

DANGER: EXPLOSIVE AND FLAMMABLE! If the appliance is for connection to natural gas, the gas connections should be made by a qualified installer or a licensed plumber. The gas-supply line must not be installed by the consumer.

The valve-orifices and fuel supply hose system necessary for use with natural gas is different than the system required for L.P. gas. Modification to the burner valve/orifices allow the use of natural gas. An L.P. cylinder is not needed.

WARNING: Do not use liquid propane (L.P.) gas in an appliance designed for natural gas. Use only natural gas in an appliance designed for natural gas.

INSTALLATION FOR NATURAL GAS

The maximum inlet supply pressure is 11.0" w.c. for propane gas and 7.0" w.c. for natural gas.

The specified supply pressure is 11.0" w.c. for propane gas and 7.0" wc. for natural gas.

The piping system should be installed by a qualified service technician in accordance with the National Fuel Gas Code (NFPA 54/ANSI

Z223.1) in the U.S.A., including:

1.The appliance and its individual shut-off 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).

2.The appliance must be isolated 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 psi (3.5 kPa).

A quick-connect coupling sleeve with 3/8” female end is provided. Install the connector socket at the pipe end, after the shut-off valve. This must be installed where the grill will be in use.

It is important to observe the safety guidelines for choosing a safe location. The gas supply must be shut off prior to installation of the quick connector socket. Use only a matching factory authorized quick-connect plug with the quick-connect socket.

Natural-gas units are equipped with a 12- footlong quick-connect fuel hose in place of the shorter hose/regulator attached to the burner valve.

Prior to inserting, turn on gas supply and test all connections with an ammonia-free soap and water solution. Apply this solution to the stem of the shut-off valve and opening of the socket to detect leaks. (See Leak Testing Natural Gas Connections on the following page).
