Quadra-Fire QV32-A Ceiling Firestop Ceiling Side, Hole & New Framing Members, Attic Firestop

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 11-inch X 11-inch (280mm X 280mm) for D-Series or a 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.

If the area above the ceiling is NOT an attic, position and secure the ceiling firestop on the ceiling side of the previously cut and framed hole.
