PROBLEM TO BE SOLVED: To provide a technology capable of accurately measuring an air supplying temperature by using a single air supplying temperature sensor when a combustion device is installed under a double-pipe system and also when the combustion device is installed through a two-pipe system.SOLUTION: A combustion device comprises a supply/exhaust port formed in such a way that a supply passage encloses an outside of an exhaust passage and a supply port where a supply passage is formed. The supply passage of the supply/exhaust port and the supply passage for the supply port are communicated with a space in a casing. When the combustion device is installed through the double-pipe system, the supply passage for the supply port is closed, and when the combustion device is installed through the two-pipe system, the supply passage for the supply/exhaust port is closed. There are provided a supplying temperature sensor for measuring a supplying temperature in the space in the casing and a guide member for guiding air flowing into the space in the casing to the supplying temperature sensor near the supply passage for the supply/exhaust port and/or near the supply passage for the supply port. |
