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) hole through the ceiling, using the centerpoint previously marked.

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