Quadra-Fire QV-ST, QV-PIER owner manual Continue Adding Vent Components

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 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.

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 10-inch X 10-inch (254mm x 254mm) hole through the ceiling, using the centerpoint previously marked.

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