ENERGIZATION SYSTEM WITH SAFETY PROVISION FOR FAULTY RECTIFIER

摘要

A fail-safe spark ignition system for gas burners includes a spark energy monitoring circuit for controlling the gas valve and bimetal spark gap disabling means for eliminating radio interference. Two circuit arrangements are shown for protection against short circuit failure of rectifiers energizing the gas-valve solenoid or other load from an AC power source, using a second rectifier and a fuse or fusible resistor for circuit disconnection.
