PURPOSE:To enable a changing-over ignition between a hot water burner and a bath burner to be carried out by a method wherein a hot water feeding valve may form a supplying passage for the hot water burner with the water being passes through a hydraulic responding device, a bath valve may shut off the supplying passage for the bath burner, a closing element may rotate an operating shaft to form a supplying passage for the bath burner. CONSTITUTION:A hot water feeding valve 20 and a bath valve 20 are provided for changing-over and forming a gas supplying passage for a hot water feeding burner and a bath burner. They are pushed and operated to cause a pilot burner to be ignited and an operating shaft 13 to be held at a predetermined operating position has a tapered hollow closing element 19 which can be pivoted around this operating shaft. The hot water feeding valve 20 and the bath valve 21 are supported and fixed at their one ends to an elongated pushing lever 19 fixed to the hydraulic responding device 18 by hydraulic pressure applied by passing water coaxially and spaced apart by a predetermined spacing. In turn, the bath valve may shut off the supplying passage for the bath burner, and the closing element 19 may rotate the operating shaft 13 to form the supplying passage for the the bath burner. |
