The Fenwal Series 05-14 ignition/proof-of-flame system is adaptable to all types of gas equipment. This versatile unit eliminates the need for gas consuming pilot burners by providing positive ignition of main burners when heat is required. The ignition spark operates until the flame is established and then immediately shuts off. Flame sensing is achieved through the flame rectification principle and is positive. If, after a try-for-ignition, a flame is not present, the unit then automatically removes power from the gas valve. The flame sense electrode can he mounted remotely from the high voltage electrode assembly to assure that the proper flame envelope has been developed or mounted locally as an integral part of the high voltage electrode assembly. The unit may be connected either to retry for ignition or to lockout immediately in the event of a loss of flame. Resetting, after a lockout, may be accomplished by either cycling the thermostat or by manually resetting a thermally actuated circuit breaker, depending upon the model selected. The circuit breaker is present in all models to protect the unit from malfunctions. The unit is potted in a plastic case using a clear plastic resin and provides increased resistance to damage caused by shock and vibration and the detrimental effects of severe environ
