PURPOSE:To make it possible to perform a gas igniting operation and a hot water supplying operation by a single operation with a small operating force by opening a water plug to allow the titled heater to assume a water feeding state, and automatically pushing an electromagnetic valve to carry out attraction and opening. CONSTITUTION:When the water valve (V6) is opened, a diaphragm 6 moves to the side of a secondary chamber (2b) due to the supply water pressure, and an instrument valve V is separated from a valve seat 16 to open the upstream side of a gas supply passage 9. At the same time, since a diaphragm 19 moves to the side of a secondary chamber 3b, a gas valve V4 is pushed to the left, and the midstream part of the gas supply passage 9 is opened. Further, a switch S1 is manipulated to change over a capacitor to the side of an electromagnet M, attracting an iron piece 13 and opening an electromagnetic safety valve V1. Then, a switch S2 is manipulated, and gases supplied to primary and secondary pilot burners P1 and P2 are successively ignited. Thereafter, when the pushing force applied on a push button 29 is released, the push button 29 is locked by means of a locking device 39, and resetting valve V5 opens the downstream side of the gas supply passage 9, supplying gas to a main burner C and igniting the gas by a burner P2 which has been previously ignited. |
