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

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
•Frame the hole with framing lumber the same size as the ceiling joists.
