For Gas-Fired Steam Generators: Post in a prominent location, instructions to be followed in the event the user smells gas. This information shall be obtained by the consulting the local gas supplier.

Install a sediment trap (drip leg) in the gas supply line, and then connect gas supply piping to the boiler gas valve piping. GAS-FIRED EQUIPMENT IS DESIGNED FOR INSTALLATION ONLY IN NONCOMBUSJJBLE LOCATIONS. THIS INCLUDES THE FLOOR-INC THAT WILL BE DIRECTLY UNDER THE EQUIPMENT Location, plumbing size, and pressure data are shown on the specification sheet. Boilers rated at less than 225,000 Btu require 3/4-inch 'PS gas supply piping, and boilers rated at 225,000 Btu or more require 1-inch II'S gas supply piping. Natural gas pressure must be between 4" -14" water column and LP gas supply pressure must be between 12"

-14" water column. NEVER EXCEED 14" WATER COLUMN (1/2 psi) GAS PRESSURE. If the gas supply pressure exceeds 14" water column, a pressure-regulating valve must be installed in the gas plumbing to reduce the gas pressure to less than 14" water column. Installation must be in accordance with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1-1984. Installation in Canada must be in ac- cordance with Installation codes for Gas Burning Appli- ances and Equipment B149.1 and B149.2. Use a gas pipe joint compound, which is resistant to LP gas. Turn the gas valve control knob to ON (the word "on" the knob will be opposite the index on the valve's body). Test all pipe joints for leaks with soap and water solutions. Never obstruct the flow of combustion and ventilation air Observe all clearance requirements to provide adequate air openings into the combustion chamber. The appliance and it's indi- vidual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 14" water column (1/2 psi or 3.45 k}'a). The appliance must be isolated from the gas supply piping system at test pressures equal to or less than 14" water column (1/2 psi or 3.45 kpa). A perma- nent 115-volt electrical connection is required at the junc- tion box. The junction box location is shown on the speci- fication sheet. The installer must electrically ground the unit.

For Electric-Powered Steam Generators: Connect

electric power: location and data are shown on the specification sheet. Provide connection as required by the unit, either directly to the single contactor, or to the terminal block (when equipped with multiple contactors). Electric supply must match power requirements specified on the data plate inside the base cabinet. The copper wiring size must be adequate to carry the required current at the rated voltage. A separate fused disconnect switch must be supplied and installed. The installer must electrically ground the unit

For Steam Coil Steam Generators: Connect steam supply piping to the input side of the steam coil. Location

and pressure data are shown on the specification sheet. Incoming steam pressure must be regulated between 35 and 45 psi. A 3 /4inch strainer, equipped with a 20 mesh stainless steel screen, must be supplied and installed at the incoming steam connection point. Flush the steam line thoroughly before connecting it to the boiler. To ensure an adequate volume of steam, the branch steam supply line must be 3/~inch 'PS minimum. Connect the inverted bucket trap to the outlet end of the steam coil. Pill the trap with water before installing it. A permanent 115-volt electrical connection is required at the junction box. The junction box location is shown on the specification sheet. The installer must electrically ground the unit.

For Direct-Steam Connected Steamers and Kettles:

Connect steam supply piping to the input side of the line strainer. Location and pressure data are shown on the specification sheet. Flush the steam line thoroughly before connecting it to the steamer. To ensure an adequate volume of steam, the branch steam supply line must be 3/4 inch 'PSI 'minimum. Direct-steam-connected kettles require 1 /2-inch 'PS pipe if the kettle total capacity is 20 gallons or less, and 3/4-inch 'PS pipe if the total capacity exceeds 20 gallons.) A permanent 115 volt electrical connection is required at the junction box. The junction box location is shown on the specification sheet. The installer must electrically ground the unit

Proper operation of the Cleveland Convection Steamer is dependent upon proper installation. After the steamer has been installed, a few quick checks could save unnecessary service calls.

1.The unit must be level.

2.The Convection Steamer requires a cold water connec- tion for proper efficient operation. DO NOT USE HOT WATER. The cold water must be connected to the line strainer, located at the front lower right of the steamer base.

3.Check that the manual water supply valve is open.

4.Check all water supply lines and valves for leaks.

5.Check that the water supply pressure and water quality meets the requirements of installation paragraphs.

6.On electrical units, verify that the supply voltage meets the voltage requirements on the rating plate inside the base cabinet and the voltage shown on the packing slip. Verify that the unit is protected with a separate fused disconnect and is properly grounded in accordance with the National Electric Code.
