Firestops
For Vertical Runs - One ceiling firestop is
REQUIRED at the hole in each ceiling through which
the vent passes.
To install firestops for vertical runs that pass through
ceilings:
• Position a plumb bob directly over the center of the
vertical vent component.
• Mark the ceiling to establish the centerpoint of the
vent.
• Drill a hole or drive a nail through this centerpoint.
• Check the floor above for any obstructions, such as
wiring or plumbing runs.
• Reposition the stove and vent system, if necessary,
to accommodate the ceiling joists and/or obstruc-
tions.
• Cut an 10” x 10” (254mm X 254mm) hole through
the ceiling, using the centerpoint previously marked.
• Frame the hole with framing lumber the same size
as the ceiling joists.
1. Cut the 10” x 10” hole.

members.
