Abstract: An ignition/reignition device for a gas burner which eliminates the isolation transformer of the prior art which includes a capacitive discharge curcuit which is connected to a high voltage transformer so as to provide ignition pulses to ignite a gas burner and which has a flame current amplifier and flame rectification sensors connected to the capacitive discharge circuit so as to control it so that spark discharges will occur if the burner has been turned on and such sparks will continue until ignition and wherein upon disappearance of the flame the sparks will again occur to reignite the burner.
