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 heater and flue system, if necessary, to
accommodate the ceiling joists and/or obstructions.
• Cut a 10 in. x 10 in. (254 mm x 254 mm) hole through
the ceiling when using DVP pipe, and a 9 in. x 9 in.
(229 mm x 229 mm) hole when using SLP pipe. Use
the firestop pipe opening as a guide.
• Frame the hole with framing lumber the same size as
the ceiling joists.
