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

firestop on an exterior combustible wall.

through either interior or exterior walls:
• Cut a 12-inch by 12-inch (305 mm X 305 mm) hole
through the wall. The center of the hole is one (1)
inch (25.4 mm) above the center of the horizontal
vent pipe.
