2. Continue Adding Vent Components
Refer to Termination Cap installation instructions.
• Continue adding vent components, locking each suc-
ceeding component into place using the PV-connect.
• Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system. Securing pipe sections with three screws
is recommended.
3. Install Support Brackets
Refer to 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 PV-HORZ CAP does not need an exte-
rior firestop on an exterior combustible wall. The
firestop is built into the cap.
To install firestops for horizontal runs that pass through
interior walls:
• Cut a 9” x 9” (229mm X 229mm) hole through the wall.
• Position the firestop on one side of the hole previously
cut and secure the firestop with nails or screws.
• Continue the vent run through the firestop.
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 ver-
tical 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 a 9-inch X 9-inch (229mm x 229mm) hole through
the ceiling, using the centerpoint previously marked.
• Frame the hole with framing lumber the same size as
the ceiling joists.

B. Installing Vent Components
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars
of the fireplace:
• Slide the first vent section of pipe onto the starting col-
lar until it covers the entire starting collar.
• Tighten the hose clamp to secure the pipe to the start-
ing collar.
• Using self tapping screws secure the pipe to the collar
with three screws.
