PROBLEM TO BE SOLVED: To effectively and inexpensively prevent temperature rising in the rear of a stove body. SOLUTION: A hot air suction port 12 is installed in the upper vicinity of a burner 4, and a fan air supply cylinder 13 for introducing combustion gas in a blast fan 11 is installed in the rear of the burner 4. An upper cold air suction port 14 for sucking air for cooling sending combustion gas to appropriate temperature with no danger of a burn or the like is installed in the rear upper part of the fan air supply cylinder 13. The inside of the fan air supply cylinder 13 is divided into a hot air passage 19 on the body front side communicating with the hot air suction port 12 and a cold air passage 20 on the body rear side communicating with the upper cold air suction port 14 with a partition plate 18 to the midway. Heat conduction from high temperature combustion gas to the body rear side is blocked with the cold air passage 20, the temperature rising on the body rear side is prevented, and safety is enhanced.
