    Default 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)???
