An apparatus for heating water comprises a main burner, a pilot burner, a valve assembly with a main valve and a pilot valve having a shutter, a magnetic thermoelectric safety assembly with a thermocouple device holding the pilot valve open in the presence of a flame in the pilot burner, a button member mounted on a rod that is slidingly guided in the valve assembly and an electrical ignition member supplied via an electrical connection circuit, a switch device in the circuit being designed to be switched by means of the button member so as to close the electrical circuit when said button member is pressed in order to carry out actuation of the magnetic assembly so as to open the passage of gas through the pilot valve towards the pilot burner and to ignite the pilot flame by means of the sparks generated by the ignition member.

Water-heating apparatus comprising combustible gas burner, in particular a storage water heater

Control system for controlling the pilot flame of a combustible gas device, which includes a pilot burner, a main burner, and a valve assembly, which includes a pilot valve that allows/intercepts a flow of gas directed towards the pilot burner, and a main valve that allows/intercepts a gas flow to the main burner, the valve assembly moveable between a closed OFF state, a PILOT state, and an ON state, where gas flows to the main burner. The control system includes a detection device that generates a state signal, and a control unit including a timer, the control unit is operatively connected to the detection device to receive a state signal and to an actuator to close the valve. The control unit starts the timer when the state signal represents the PILOT state, and actuates the actuator for the pilot valve to close it when the timer reaches a preset limit.
