Abstract

Control method for a circulating water heater (1) with a sealed combustion chamber (2) and removal by suction of the waste gases supported by a fan (10), the circulating water heater being fed from a gas pipe (28) provided with a valve (27, 29) and monitored by a flame sensor (31), and there being provided a control and regulating device (15) which governs the fan and the gas valve. According to the invention, in the event of non-closure of the gas valve (29) in spite of a corresponding command of the control or regulating device (15), the fan (10) is operated further, when the flame sensor (31) signals a flame. <IMAGE>
