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 verti-
cal 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 wir-
ing or plumbing runs.
• Reposition the fireplace and vent system, if necessary,
to accommodate the ceiling joists and/or obstructions.
• Cut an 11-inch X 11-inch (280mm X 280mm) hole through
the ceiling, using the centerpoint previously marked.
• Frame the hole with framing lumber the same size as the
ceiling joists.

ously cut and secure the firestops with nails or screws.

wards the top of the hole.

For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.

firestop on an exterior combustible wall.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
• Cut a 12” x 12” (305mm x 305mm) hole through the wall.
NOTE: The center of the hole is one (1) inch (25.4mm)
above the center of the horizontal vent pipe.
