Foreign material in the burner and gas controls willcause improper and dangerous operation.A. The gas supply (service) line must be the same size or greater than the fryer inlet line. This fryeris equipped with a 22 mm (3/4") male inlet. The gas supply line must be sized to accommodateall the gas-fired equipment that may be connected to that gas supply. Consult your contractor,gas company, supplier, or other knowledgeable authorities.Recommended Gas Supply Line SizesGas Types Number of Fryers1 2 to 3 4 or more (*)G20 and G25 22 mm (3/4") 28 mm (1") 35 mm (1-1/4")G31 15 mm (1/2") 22 mm (3/4") 28 mm (1")(*) When exceeding 6 meters (18 feet) for a configuration of more than four fryers, it is necessaryto provide a 35 mm (1-1/4") rigid gas connection.DANGERAll connections must be sealed with a joint compound suitable for the gas beingused and all connections must be tested with a solution of soapy water beforelighting any pilots.Never use matches, candles, or any other ignition source to check for leaks. If gasodors are detected, shut off the gas supply to the appliance at the main shut-offvalve and immediately contact the local gas company or an authorized serviceagency for service.DANGER"Dry-firing" your unit will cause damage to the frypot and can cause a fire. Alwaysensure that melted shortening, cooking oil or water is in the frypot before firing theunit.B. Rigid Connections: Check any installer-supplied intake pipe(s) visually and clean threadingchips, or any other foreign matter before installing into a service line. If the intake pipes are notclear of all foreign matter, the orifices will clog when gas pressure is applied. Seal pipe jointswith a sealant resistive to G31 gas. When using thread compound on gas piping, use very smallamounts and only on male threads. Use a pipe thread compound that is not affected by thechemical action of G31 gases. DO NOT apply thread compound to the first two pipe threads—doing so will cause clogging of the burner orifices and control valve.
