Beschreibung
Zusammenfassung:	A combustion device includes a solenoid valve configured to open and close an inflow port and an additional solenoid valve configured to open and close a communication port selectively mountable at an upstream end of a distribution flow passage with a small number of nozzles. When the additional solenoid valve is mounted, a state of supplying a fuel gas to only a distribution flow passage with a large number of the nozzles by opening the solenoid valve and closing the additional solenoid valve and a state of supplying the fuel gas to two distribution flow passages by opening the solenoid valve and opening the additional solenoid valve are mutually switchable. When the additional solenoid valve is not mounted, a state of supplying the fuel gas to the two distribution flow passages by opening the solenoid valve and a state of not supplying the fuel gas are mutually switchable.
