Abstract:
A device for controlling the supply of gas to gas burners, comprising:a main supply duct for supplying gas,a safety valve disposed in said main supply duct and having an actuator with a manual arming member for manual arming of the actuator,a regulation valve disposed in said main supply duct downstream of the safety valve for supplying gas to a main burner,a tapping duct connected to said main supply duct between the safety valve and the regulation valve for supplying gas to a pilot burner,a flame detector associated with the pilot burner and connected to the actuator of the safety valve for supplying the actuator of the safety valve with sufficient energy to hold the safety valve open after the manual arming by said manual arming member, when a flame is present in the pilot burner,a branch duct connected to said main supply duct between the safety valve and the tapping duct for supplying gas to a secondary burner, and an on/off valve disposed in the branch duct and having operating means for controlling the supply of gas to the secondary burner, mechanical means for coupling the operating means to the manual arming member of the actuator of the safety valve for maintaning closing of the on/off valve during manual arming to prevent the supply of gas to the secondary burner, until the main burner is lit.
