DECATHLON SERIES GAS FRYERS (NON-CE)CHAPTER 3: INSTALLATION3-43.4 Gas Connections (cont.)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 arenot clear of all foreign matter, the orifices will clog when gas pressure is applied. Seal pipejoints with a sealant resistive to LP gas. When using thread compound on gas piping, usevery small amounts and only on male threads. Use a pipe thread compound that is notaffected by the chemical action of LP gases. DO NOT apply thread compound to the firsttwo pipe threads—doing so will cause clogging of the burner orifices and control valve.C. Manual shut-off valve: This gas service supplier-installed valve must be installed in the gasservice line ahead of the fryers in the gas stream and in a position where it can be reachedquickly in the event of an emergency.D. Regulating Gas Pressure: The fryer and shut-off valve must be disconnected from the gassupply during any pressure testing of the system.1. External gas regulators are not normally required on this fryer. A safety control valveprotects the fryer against pressure fluctuations. If the incoming pressure is in excess of½" PSI (3.45 kPa/35 mbar), a step-down regulator will be required.DANGERWhen pressure-testing incoming gas supply lines, disconnect the fryer from the gasline if the test pressure is ½" PSI [3.45 kPa (14 inches W.C.)] or greater to avoiddamage to the fryer’s gas piping and gas valve(s).
