A device for automatically controlling the operation of a burner comprises an electric control unit which controls the ignition and the flame of the burner and which opens a normally-closed solenoid valve disposed in a first fuel-supply line to the burner, and a pilot burner for the burner supplied by manually-operable second regulation and safety valve means operatively associated with the control unit and disposed in a second fuel-supply line to the burner, the second valve means being openable manually and being kept open by a current I generated by a thermocouple in the presence of a flame of the pilot burner when the control unit is de-activated and advantageously being closable by the control unit against the action of the current I when the control unit is activated. |
