PROBLEM TO BE SOLVED: To reduce the number of parts of a combustion air conditioner and build it up using a steel plate, which can be worked at a lower cost, for fixing combustion parts thereto by providing the steel plate for fixing combustion parts with a space which is communicated with a blowing chamber and a machine chamber. SOLUTION: A blowing chamber side space 11a is formed in a longitudinal direction at a front surface portion of a steel plate 5 for fixing combustion parts located at an upper portion of a blowing chamber 4a, while a machine chamber side space 11b is formed in a longitudinal direction at a front surface portion of the steel plate 5 located at an upper portion of a machine chamber 2a. Opening areas of the individual spaces are in a relation, space 11b < space 11a. A combustion blower 6 mounted in a combustion chamber 7a sucks air flowed from the machine chamber 2a and the blowing chamber 4a to the combustion chamber 7a through the space 11a and the space 11b, respectively, and blows the air to a combustor 7. Since the machine chamber 2a does not comprise an inlet port for directly taking outside air because of plate metal parts, the amount of air sucked in the individual spaces is in a relation: space 11b < space 11a.
