A gas flow control circuit comprises a serial combination of SCR, an intermediate resistance (RF) which is preferably fusible and a gas control solenoid (SOL). A diode is connected in parallel with the solenoid (SOL). The anode of the SCR is connected to one end of the resistance (RF) and the anode of the diode is connected to the other end of the resistance (RF). <IMAGE> |
