Use an approved <br />gas pipe sealant at <br />all external threaded <br />connections, gas <br />piping used on gas <br />connections must <br />avoid sharp bends <br />that may restrict the <br />flow of gas to the <br />appliance. if the <br />connected pressure <br />exceeds 14.0” W.C. (3.5 kPa), a step-down regulator is <br />required to be supplied by the owner/operator. <br />close the individual manual shut-off valve to <br />isolate the fryer from the gas supply piping system <br />during any pressure testing at test pressures equal <br />to or less than 1/2 psig. (3.4 kPa). The fryer and <br />individual shut-off valve must be disconnected <br />from the gas supply piping system during <br />any pressure testing at pressures in <br />excess of 1/2 psig. (3,4 kPa). <br />in the U.S.a., installation must conform to local <br />codes or, in the absence of local codes, with the <br />current edition of the National Fuel Gas Code, <br />NFPA-54 and ANSI Z83.11a CSA 1.8a 2004 (or <br />latest edition). In Canada, installation must be in <br />accordance with local codes, CAN/CGA-B149.1, <br />Installation for Natural Gas Burning Appliances <br />and Equipment (latest edition) or CAN/ <br />CGA-B149.2 Installation for Propane Burning <br />Appliances and Equipment (latest edition). <br />the inlet supply line must be properly sized <br />to accommodate all individual appliances <br />simultaneously used on the same line but must <br />never be smaller than 3/4” i.d. <br />LEAK TESTING <br />installation requires gas leak testing on all gas <br />piping and fittings. Use an approved electronic <br />leak device or a soap and water solution at all gas <br />connections. if bubbling appears when using a soap <br />and water solution, the connection must be refitted. <br />Never use an open flame to leak test. <br />INCORRECT CORRECT <br />A <br />B <br />C <br />D <br />E <br />F <br />G <br />H <br />GAS INTAKE <br /> A-G Installation elbow <br /> B Wall Valve <br /> C-D Three-piece union fitting <br />(minimum 1 per installation) <br /> E-F End connector for the flexible tube <br /> H Marking line <br />GAS CONNECTION <br />dANGER <br />Installation, air adjustment and/or <br />service work must be in accordance <br />with all local codes and must be <br />performed by a certifi ed service <br />technician qualifi ed to work on <br />gas appliances. <br /> dANGER <br />NEVER USE AN OPEN <br />FLAME TO LEAK TEST. <br />INSTALLATION <br />Gas Fryer Operation & Care Manual • 8
