PROBLEM TO BE SOLVED: To easily set the control conditions of an altitude and an extension pipe in a control mode setting device of a combustion machine. SOLUTION: The control mode setting device of the combustion machine comprises a central control part 9 having a plurality of control conditions such as combustion air/fuel corresponding to the altitude and the extension pipe, a storage means 16 selecting one of the plurality of control conditions of the central control part 9 and writing as mode selection information, and set switches 6 and 7 installed on an operating part 1. When the set switches 6 and 7 on the operating part 1 are specifically operated differently from normal operations, the device comes into a mode setting state in which the control conditions corresponding to the altitude and the extension pipe can be set in order, and the mode selection information corresponding to the altitude and the extension pipe is selected from among the plurality of the control conditions. In the mode selection information corresponding to the altitude and the extension pipe, limiters are installed at the lower limits of a fuel supply amount and a combustion air supply amount in an altitude mode and the long pipe mode other than standard modes to prevent the combustion amount from being lowered to a specified limit or below.
