- PROBLEM TO BE SOLVED: To prevent heat loss of an electronic control unit 6 and a fan motor 52 without causing a problem of noise and restricted by an installation position and a combustion capacity, in a forced air supplying/exhausting type combustion device including a combustion box 2 accommodated in a housing 1 and incorporating a burner 3, an inner and outer double air supplying/exhausting pipe 7 constituting an exhaust passage 7a communicated with the combustion box, and an air supply passage 7b around the exhaust passage, and a combustion fan 5 for supplying the air flowing into the housing from an outdoor side through the air supply passage as combustion air of the burner.SOLUTION: A control chamber 1b partitioned to a main space 1a accommodating a combustion box 2 and a fan casing 51 of a combustion fan 5, is disposed in a housing 1. An air supply passage 7b is communicated with the main space 1a, and an electronic control unit 6 and a fan motor 52 are accommodated in the control chamber 1b.
