The top of the obstacle is a tornado collar secured, not secured, to the chimney. Above the ceiling, the air and vapour barrier is covered around the drywall to contact the firestop sealant.


A collar-like ceiling trim plate is connected listed below the firestop. Job securely around electric wiring (transform off the power).
