For Vertical Runs - One firestop is REQUIRED at the hole
in each ceiling through which the flue passes.
To install firestops for vertical runs that pass through
ceilings:
• Position a plumb bob directly over the center of the
vertical flue component.
• Mark the ceiling to establish the centerpoint of the flue.
• Drill a hole or drive a nail through this center point.
• Check the floor above for any obstructions, such as
wiring or plumbing runs.
• Reposition the fireplace and flue system, if necessary,
to accommodate the ceiling joists and/or obstructions.
• Cut a 9 in. x 9 in. (229 mm x 229 mm) hole through the
ceiling when using SLP pipe. Use the firestop pipe open-
ing as a guide.
• Frame the hole with framing lumber the same size as
the ceiling joists.
