INSTALLATION STRATOSTEAM COUNTERTOP STEAMER

STEP 5: GAS CONNECTION

The data plate on the front of the base indicates the type of gas your steamer is equipped to burn. DO NOT connect to any other gas type.

Keep the appliance area free and clear from combustible substances. Do not obstruct the flow of combustion and ventilation air.

A 1/2" NPT (1.27 cm) threaded fitting is provide at the rear of the steamer for the gas supply connection (Fig. 6). Each steamer is equipped with an internal pressure regulator which is set at 4" W.C. (0.99 kPa) manifold pressure for natural gas or 10" W.C. (2.49 kPa) for propane gas.

An adequate gas supply is necessary. Undersized or low-pressure lines will restrict the volume of gas required for satisfactory performance. A steady supply pressure from 7" W.C. (1.75 kPa) for natural gas and from 10" W.C. (2.49 kPa) for propane gas is recommended. With all steamers and other gas appliances operating simultaneously, the manifold pressure on all appliances should not show any appreciable drop. Fluctuations of more than 25% on natural gas and 10% on propane gas will create problems and affect burner operation. Contact your gas company for correct supply line sizes.

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

Use pipe joint compound that is resistant to the action of liquefied petroleum or propane gases on all threaded connections.

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

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 steamer to the electrical supply until after the gas connection has been made.

TESTING THE GAS SUPPLY PIPING

When test pressures exceed 1/2 psig (3.45 kPa), the steamer and its individual shutoff 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 steamer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the system.
