摘要

The chimney assembly (300) comprises a drainage relief channel (23) with an output mouth (25) and a flue gas discharge channel (22) provided with an outflow mouth (24) or particularly a ventilation air discharge channel. The output mouth of the drainage relief channel is open in the gas flow (18) during use through the gas discharge channel. The chimney assembly has a chimney placed on the roof of a building, in which the outflow mouth is provided. The gas discharge channel is provided with a fan, which during operation is effective in the direction of the outflow mouth of the gas discharge channel. The chimney is also provided with an inlet mouth of an air inlet channel. The outflow mouth of the gas discharge channel is directed upwards. The drainage relief channel has a channel end (26) which issues into the outflow mouth and is located in the gas discharge channel, at least in the area flowed through by the gas current during operation.
