HIGH EFFICIENCY DECATHLON SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.1 Functional Description High Efficiency Decathlon (HD) Series gas fryers contain a welded stainless steel frypot heated by gas flames diffused evenly through tubes built into the frypot. Flames originate from orifices in a burner manifold positioned beneath cast-steel burners. The burners are positioned in the tube openings at the front of the frypot. The diameter of the orifices differs for natural

HIGH EFFICIENCY DECATHLON SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.1 Functional Description (cont.) Pilot System Configuration The pilot system is comprised of the pilot orifice, pilot hood, and a thermopile (some systems incorporate a thermocouple). The pilot serves two purposes: light the burner and heat the thermopile. In operation, the thermopile is in contact with the pilot flame and generates millivolts. The millivolt output energizes the gas valve pilot coil,

HIGH EFFICIENCY DECATHLON SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES Thermostats Different types of thermostats are used in High Efficiency Decathlon Series gas fryers, depending on fryer configuration. Fryers equipped with a Thermatron use a dial to adjust temperature. In this configuration, the probe resistance varies inversely with the temperature. As the temperature rises, resistance decreases at a non-linear rate. A chart is located at the end of this chapter. Frye

HIGH EFFICIENCY DECATHLON SERIES GAS FRYERS CHAPTER 1: SERVICE PROCEDURES Restraints Once the fryer has been positioned at the frying station, use a carpenter’s level placed across the top of the frypot to verify that the unit is level, both side-to-side and front-to-back. To level fryers equipped with legs, the bottom of the legs can be screwed out up to one inch for leveling. Legs should also be adjusted so that the fryer(s) are at the proper height in the frying station. For
