To provide a forced flue combustion device which has a compact-sized device main body, does not have a gap formed between a wall and the device main body due to connection piping of supply anti exhaust pipes and can be installed by closely fitting the main body to the wall.
Discharge of exhaust gas after combustion and supply of combustion air are executed from outdoor through a forced flue duct 1 having a double pipe structure. A terminal part 10 is a connection part connecting an exhaust pipe 16 of the device main body side 13 of the forced flue pipe 1 and an air supply pipe 17, is disposed in an approximately central position in a vertical direction at a side biased in one side in a frame 14 of the main body 13, and a combustion fan 26 is provided in an inclined posture in a front/rear direction. Therefore, the connection piping, i.e., the exhaust pipe 16 and the air supply pipe 17 is prevented from being exposed out of the frame 14, the main body 13 is fitted closely to the wall 2 and the combustion fan 26 can be installed in the most compact configuration so that the main body can be constituted in a compact and slim form.
