PURPOSE:To permit the uniform blow-off of warm-air into a room and contrive the shortening of the lateral width of the titled machine by a method wherein a warm-air blow-off port is formed long in the lengthwise direction of the blow-off port and an air passageway, communicating with a combustion chamber, is connected to the tongue section of a crossflow fan with a smooth curve. CONSTITUTION:A warm-air blow-off port 12, provided on the front surface of the main body 8 of the titled machine formed so as to have a narrow width and a long length as well as a shape slender in the vertical direction of the blow off port, is allowed to communicate with a fan case 14a and another fan case 14b, constituting an air passageway 10a and the airflow passage way of a crossflow fan 13, used as a circulating fan and provided in vertical direction. Accordingly, the delivery port 15 of the crossflow fan 13 becomes the warm-air blow-off port 12 and the suction direction of a suction port 16 is curved with a curve by the fan case 14a constituting integrally the tongue section 17 of the crossflow fan 13 and is constituted so as to communicate with the air passageway 10a. Accordingly, the flow direction of air in the air passageway 10a becomes the same as the flow direction of the air in the warm- air blow-off port 12.
