4.4.4 Vertical Firestops
Firestops are required for safety whenever the vent system passes through an interior wall, an exterior
wall, or a ceiling. These firestops act as a firebreak heat shield and as a mean to insure that minimum
clearances are maintained to the vent system.
Vertical runs of this system which pass through ceilings require the use of ONE ceiling firestop at the hole
in each ceiling through which the vent passes.
Position a plumb bob directly over the center of the vertical vent component and mark the ceiling to
establish the center point of the vent. Drill a hole or drive a nail through this center point and check the
floor above for any obstructions such as wiring or plumbing runs.
Reposition the fireplace and vent system, if necessary, to accommodate ceiling joists or obstructions.
Cut a 10-5/8 inch x 10-5/8 inch hole through the ceiling, using the center point previously marked. Frame
the hole with framing lumber the same size as the ceiling joists.
