2. Continue Adding Vent Components
Refer to Cinch Pipe and Termination Cap installation in-
structions.
• Continue adding vent components, locking each succeed-
ing component into place.
• Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system. Securing pipe sections with a maximum of
two screws is recommended.
• 90° elbows may be installed and rotated to any point
around the preceding component's vertical axis. If an el-
bow does not end up in a locked position with the pre-
ceding component, attach with a minimum of two (2)
sheet metal screws.
3. Install Support Brackets
Refer to Cinch Pipe and Termination Cap installation in-
structions.
4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVP-TRAP does not need an exterior
firestop on an exterior combustible wall. The firestop is
built into the cap.
To install firestops for horizontal runs that pass through either
interior or exterior walls:
• Cut a 10" x 12" (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 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.
