SUPER MARATHON SERIES GAS FRYERSCHAPTER 2: IMPORTANT INFORMATION2-22.2 General (cont.)Dean Super Marathon Series gas fryers are energy efficient, open frypot, gas-fired units. All unitsare shipped completely assembled, with accessories packed inside the frypot. All units are adjusted,tested, and inspected at the factory prior to crating for shipment.WARNINGThe on-site supervisor is responsible for ensuring that operators are made aware ofthe inherent dangers of operating a hot-oil fryer/filter system, particularly theaspects of fryer operation, oil filtration, and draining/cleaning procedures.2.3 Principles of OperationThe incoming gas flows through orifices and is mixed with air in the burners to create the correctratio for proper combustion. The mixture is ignited at the front end of each heat tube by the pilotlight. Internal diffusers slow the flame as it goes through the burner tube. This slower and moreturbulent flame gives much better heat transfer to the walls of the tubes, thereby heating the oil moreefficiently.2.4 Rating PlateDANGERFryers MUST be connected ONLY to the gas type identified on the attached ratingplate.The rating plate can be found on the inside panel of the fryer door. Information on this plateincludes the model and serial numbers, kW/hr (BTU/hr) of the burners, outlet gas pressure in mbars(inches W.C.), and configuration: natural or propane gas. Rating plate data is essential for properunit identification, communicating with the factory or requesting special parts and/or information.
