Had to turn the pipeline cover 90 degrees to reach the ventilation duct access thus I have made few modification to MOLNIGT wall mounted extractor hood.
1) Cut a piece of the upper cover as per photo attached (24×25) – this will be the opening for the duct
2) Bend the edges and attach that square with the screws as per photo
