RIES GAS RETHERMALIZERS CHAPTER 6 SERVICE PROCEDURES 6 1 Functional Description These rethermalizers contain a welded stainless steel cookpot that is directly heated by a high effi ciency burner system requiring approximately 4396 less energy than conventional burner systems to heat the same volume of water Two self contained combustion chambers referred to as burners are located beneath the cookpot Each combustion chamber is fitted with special ceramic tiles that are heated by the burning of a forced air gas mixture The tiles transfer their heat to the cookpot by means of infrared radiation providing much more constant and uniform heat dispersion over the surface of the cookpot than do conventional burners Because relatively less heat is lost to the atmosphere in the process compared to open burner designs less fuel is required to achieve and maintain a given cookpot temperature Gas flow to both of the burners is regulated by one electromechanical gas valve THE ELECTRONIC IGNITION SYSTEM Ignition modules located in the component box are connected to ignitor assemblies at each burner An ignition module performs four important functions it provides fuse protection for the 24 volt circuit provides EN an ignition spark supplies voltage to the gas valve and proofs the burner flame The module contains 4 second time delay circuit and a coil that activates the gas valve Inside the Ignition Module
