through the wall.

F. Install Support Brackets
For Horizontal Runs - The flue system must be supported
every 5 ft. (1.52 m) of horizontal run by a horizontal pipe
support. To install support brackets for horizontal runs:
• Place the pipe supports around the flue pipe.
• Nail the pipe supports to the framing members.
For Vertical Runs - The flue system must be supported
every 8 ft. (2.44 m) above the fireplace flue outlet by wall
brackets. To install support brackets for vertical runs:
• Attach wall brackets to the flue pipe and secure the wall
bracket to the framing members with nails or screws.
For Vertical Runs - One firestop is REQUIRED at the hole
in each ceiling through which the flue passes.
To install firestops for vertical runs that pass through
ceilings:
• Position a plumb bob directly over the center of the
vertical flue component.
• Mark the ceiling to establish the centerpoint of the flue.
• Drill a hole or drive a nail through this center point.
• Check the floor above for any obstructions, such as
wiring or plumbing runs.
• Reposition the fireplace and flue system, if necessary,
to accommodate the ceiling joists and/or obstructions.
• Cut a 9 in. x 9 in. (229 mm x 229 mm) hole when using
SLP pipe. Use the firestop pipe opening as a guide.
• Frame the hole with framing lumber the same size as
the ceiling joists.
