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

To install firestops for horizontal runs that pass through either interior or exterior walls:

•Cut a 10-inch by 12-inch (254mm 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 previously 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.
