The air is drawn into the air by an induced blower 12 provided in the air conditioner 1 and released into the atmosphere. Furthermore, a ninth heat exchanger 13 is provided in the middle of the exhaust pipe 11 to achieve heat exchange between the oxygen-enriched air downstream of the induced blower 8 in the first air supply pipe 7 and the combustion exhaust gas. The oxygen-enriched air is thus supplied to the burner 2 in a preheated manner.
