GAS Connection, Testing the GAS Supply Piping

GAS CONNECTION

The data plate on the lower right side of the kettle indicates the type of gas your unit is equipped to burn. DO NOT connect to any other gas type.

A 1" NPT line is provided at the rear for the connection. Each kettle is equipped with an internal pressure regulator which is set for 4" W.C. manifold pressure for natural gas or 10" W.C. for propane gas. Use the 1/8" pipe tap on the burner manifold for checking pressure.

An adequate gas supply is necessary. Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance. A maximum supply pressure of 8" W.C. for natural gas and 13" W.C. for propane gas is recommended. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable drop. Fluctuations of more than 25% on natural gas, and 10% on propane gas, will create pilot problems and affect burner operating characteristics. Contact your gas company for correct supply line sizes.

Purge the supply line to clean out any dust, dirt, or any foreign matter before connecting the line to the unit.

Caution: The pipe thread compound used when installing pipes must be a type that is resistant to the action of liquified petroleum or propane gases.

Codes require that a gas shut-off valve be installed in the gas line prior to the kettle. Make sure the pipes are clean and free of obstructions, dirt, and piping compound.

TESTING THE GAS SUPPLY PIPING

When test pressures exceed 1/2 psig (3.45 kPa) the steam kettle and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the system. When test pressures are 1/2 psig (3.45 kPa) or less, the kettle must be isolated from the gas supply piping system by closing its individual shut-off valve during any pressure testing of the system.

WARNING: PRIOR TO START-UP, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

Do not connect the kettle to the electrical supply until after the gas connection has been made.
