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.
