In the vicinity of the inside of the filling material, we installed a piping support standing on the bottom plate,
A hot water introducing section is provided by penetrating a filler material adjacent to the one louver section across the supporting table and a pipe pillar on the supporting table side, and an inlet pipe communicating with the hot water introducing section is provided above the water receiving tank. Through the other end of the filling material to the pipe struts in the vicinity of the inside of the other filling material, and the diameter is reduced and extended, and the lower ends are connected to the large diameter portion and the small diameter portion of the inlet pipe near the inside of the two pipe struts. A rising pipe is provided, and an upper portion of the rising pipe is bent so that the inside of the filling material communicates with a sprinkler tank disposed above each filling material.
