Resumen del manual
If flowing pressure exceeds 50 psig, a pressure regulator (not supplied) must be installed in the supply line. If flowing pressure is 10 psig, use 1" piping; if over 10 psig, use 3/4" piping. Steam flow is controlled by solenoid valves. If machine is equipped with steam injector(s), one supply connection is required. For single-tank steam coil installations, two connections are required, one for supply and one for return. For two-tank steam coil installations, one common supply connection and two return connections (one per tank) are required. – 11 – GAS CONNECTION (WHEN EQUIPPED) GAS CONNECTION (WHEN EQUIPPED) The burner is not adjustable. If flowing gas pressure is above 7" W.C. (natural gas) or 11" W.C. (propane gas), an additional regulator valve (not supplied) must be installed in the supply line. Static incoming line pressure should not exceed 14.0" W.C. for either propane or natural gas. IMPORTANT: Make sure the installation meets the local code for your area.

For gas line pipe connections, use Loctite 565, Hobart part number 546292, or a flexible sealant suitable for use with Natural and Propane Gases. The appliance and its gas connections must be leak tested before placing the appliance in operation. Use soapy water for leak test. DO NOT use open flame. The installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (latest edition). Copies may be obtained from the American Gas Association, Inc., 1515 Wilson Blvd., Arlington, VA 22209. The appliance and its individual shutoff 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 psig (3.45 kPa). The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.45 kPa). Dissipate test pressure from the gas supply line before reconnecting the appliance and its manual shutoff valve to the gas supply line. CAUTION: Failure to follow this procedure may damage the gas valve. IMPORTANT: Gas heat machines must be provided with a means to exhaust the flue gases to the exterior of the building. Refer to Venting Requirements, pages 13 – 16. The dishwasher must be installed so that the flow of combustion and venti...
