Abstract
Upon a call for heat, gas flows to a pilot burner and a storage capacitor begins to charge. When sufficiently charged, the storage capacitor effects the opening of a valve controlling flow of gas to a main burner disposed in igniting relationship with the pilot burner. A hold-in circuit maintains the main burner valve open once it is opened. Circuit means connected in circuit with the storage capacitor and spark generating circuit means is responsive to the presence of charging current to the storage capacitor for preventing sparking until the storage capacitor is sufficiently charged to effect the pull-in of the main burner valve upon discharge, and is subsequently responsive to the presence of a hold-in current for terminating sparking.
