For Vertical Runs - The vent system must be supported

For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVK-01TRD does not need an exterior
firestop on an exterior combustible wall.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
• Cut a 12-inch by 12-inch (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.
• Position the firestops on both sides of the hole previ-
ously cut and secure the firestops with nails or screws.
• The heat shields of the firestops MUST BE placed to-
wards the top of the hole.
• Continue the vent run through the firestops.
NOTE: There must be NO INSULATION or other
combustibles inside the framed firestop opening.
