Field fabricated firestops for b-vent?
My understanding is that you cannot not field fabricate firestops or other passages through ceilings for b-vent - that you have to use a UL listed component:

Someone recently directed me here:

see Fig 1.8.
Are you now allowed you do this (field fabricate and caulk directly to the b-vent)???
