Assembly comprising a building with vertical external wall and an inlet/outlet pipe system with mouthpiece of the horizontal type

摘要

The invention relates to an assembly (9) of a building with a vertical wall (3) and an inlet/outlet pipe system (2) with an inlet/outlet mouthpiece (1). The pipe system extends through the vertical wall and the mouthpiece lies on the outside of the wall. Inside the building the pipe assembly is connected to a combustion plant (4). The mouthpiece has a horizontally extending inlet pipe part (11) and a horizontally extending outlet pipe part (12). The outlet pipe part extends through the interior of the inlet pipe part and projects with an outflow part beyond the inlet pipe part. The bottom of the outlet pipe part extends at a slope in order to return water of condensation to the pipe system. The outflow part is provided with a diffuser which reduces the velocity of flue gases flowing through the outflow part.
