PURPOSE:To enable natural circulation of air to be made easily and accurately by a method wherein a circulation pipe is passed through between the ridge and the ridge tiles. CONSTITUTION:A cold water pipe 9 for connecting pipe introducing ports 8 of a tank 6 to collectors 5, respectively, and a hot water pipe 10 for connecting the pipe introducing ports 8 to the collectors 5, respectively, are made to pass through between the ridge 1 and the ridge tiles 4 in such a manner that the part of each of the pipes 9 and 10 on the side of the tank 6 is made higher than the part on the side of each of the collector 5. In this case, it is possible to make the pipes 9 and 10 pass through between the ridge and the ridge tiles by cutting a part of the top of the batten 3 bridging the rafters 2. Numeral 11 designates a water-proof plate covering the cutout part. |
