relay (relay 22)
Upon the demand from the thermostat 10 being reached the relay 22 is opened thereby cutting off the voltage 25 to the thermal probe switch 20. Sequentially the electrical control circuit 50 opens the circuit providing voltage to the exciters 60; thereby shutting gas outlet valve 70 to terminate the flame 90. Thereafter the circuit.is ready for start-up again upon demand from the thermostat 10, as aforesaid.
