PROBLEM TO BE SOLVED: To provide a gas combustion apparatus capable of adjusting a gas flow rate to multiple steps with motor driving. SOLUTION: There are provided flow rate control means 28 driven by a motor such that the amount of supply of gas supplied to a burner 1 is controlled, reating power setting means for selecting heating power from a plurality of heating powers previously set to an instrument, and central control means 25 for controlling the flow rate control means 28 such that fire of the burner 1 becomes set heating power set by the heating power setting means. The flow rate control means 28 includes a flow rate adjustment section for adjusting a flow rate and closing means for opening and closing a gas passage. The low rate adjustment section is slindably moved to vary the flow rate, and further minimum flow rate gas is supplied from an independent flow rate restriction hole. |
