PROBLEM TO BE SOLVED: To reduce an offensive odor at the time of igniting or shutting down a warm air heater in a mounting structure of an adsorption oxidation catalyst sheet at a louver. SOLUTION: The warm air heater comprises a vaporizer for vaporizing a fuel supplied by a pump 13, a burner for burning a vaporized gas, a combustion cylinder 19 for guiding a combustion exhaust gas upward, a duct 21 for mixing the exhaust gas with an air flow in a room from a blower, an air outlet for exhausting warm air from a body, and a louver 24 for restricting an exhausting direction of the warm air to be exhausted from the outlet. In this case, the louver 24 has a plurality of holes each having a predetermined shape and a predetermined size arranged on its surface, adsorption oxidation catalyst sheet 25 having oxidation catalysts carried to sheet-like adsorbents each containing a prebaked sepiolite and inorganic fibers as main components integrally fixed on both surfaces of a metal plate having holders and carrying the oxidation catalysts is mounted from its rear surface. |
