PROBLEM TO BE SOLVED: To prevent a concentration of carbon monoxide contained in combustion gas from becoming high.SOLUTION: A first combustion gas passage 24a is provided at one side in the outer lateral face of an oil tank 22, and a second combustion gas passage 24b is provided at the other side in the outer lateral face of the oil tank 22. The first and second combustion gas passages 24a and 24b are spatially communicated to a first exhaust duct 25 through a first flow port 59. A partition member 70 which partitions the first combustion gas passage 24a and the second combustion gas passage 24b is provided between an opening of the first flow port 59 and a lower rear plate part 40e of the oil tank 22. Combustion gas which moves in the first combustion gas passage 24a and combustion gas which moves in the second combustion gas passage 24b move without being merged to the first exhaust duct 25 from the first flow port 59 thanks to the partition member 70.SELECTED DRAWING: Figure 6 |
