I have now reached the phase of connecting the kitchen fan to the exhaust duct. I have two options depending on how the actual duct in the chimney looks...
Option 1) Connect the kitchen fan to the duct as it is (make a hole and seal it, etc.)
or
Option 2) Connect the kitchen fan to an insert pipe if the existing duct is not sufficiently sealed
How do I handle fire and condensation protection?
Insert pipe, what type and where from?

Own villa or condominium apartment?
An exhaust duct only needs fire protection insulation on the part that is outside the room it starts in (starting from the wall/ceiling penetration), if the exhaust duct shares a channel with another kitchen fan, it should be fire-protected along its entire length except for the connection hose between the kitchen fan/exhaust duct.
I have written several posts regarding fire protection of exhaust ducts, search the forum for "imkanal" and me as the author, and you will find many suitable links to informative documents.

villa built in 1943
...then I interpret your response as that since the chimney itself is fireproof insulated, it should be okay?! What if you have a liner pipe? Condensation?
