A hot-air furnace has a long-flame burner for combusting gas or liquid fuel with a combustion chamber connected to the burner and having its length (1) and width (W1) in relationship of w1<1. A heat exchanger is located above the combustion chamber and has internally a gas flow guide plate which guides combustion gas flow discharged from the combustion chamber to the heat exchanger. The heat exchanger has a width (w2) and length (1) in the relationship of W2<1. An exhaust port for exhausting the combustion gas flow is located at the front or rear of, right or left-hand side of or on the top side above said heat exchanger. A casing has a drum integrally connecting the combustion chamber and the heat exchanger, an air flow guide and directing plate which covers the drum, a radiant heat absorber plate outside the combustion chamber, and a blower above or below the drum. A discharge port is mounted in such a manner that the direction of discharging air flow corresponds to the up or down position of the blower.
