So the Bosch DWB96DM50B comes with a 200 mm diameter ducting tube and external face plate.
It seems the neither the builder or electrician want to drill this. 200mm kit is specialist coring kit (expensive) and not something that is a regular sized kitchen hole. 152mm coring bit is simple to buy and solve (i have a 127mm bit already).
Looking on other sites the part comes with a 150mm ducting kit.
Normal airflow is 360m3 with an option for 580m3.
So the obvious question is - anyone had a similar issue? Did you simply switch from 200 to 150mm?
