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


A collar-like ceiling trim plate is connected listed below the firestop. Work safely around electrical circuitry (switch off the power).

A heavy polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling frames the electrical box.

Around the smokeshaft. Building regulations call for that air rooms between chimneys and flooring or ceiling settings up through which they pass be secured with a non-combustible fire stop (see Figure 5-3 and Number 5-4). Along the side of shared walls. There is frequently a gap in between the celebration wall (such as the shared wall between devices in duplexes, triplexes and row homes) and the edge of the attic flooring.


A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encases the electric box.

This proportion refers to unblocked vent area to the protected ceiling location.


Do not make use of electrical exhaust followers for attic room ventilation as these can draw extra air than can be provided with the soffit vents.
