F. Install Firestops
For Horizontal Runs -
Firestops are
REQUIRED
on both
sides of a combustible wall through which the flue passes.
To install firestops (heat shield) for horizontal runs that pass
through either interior or exterior walls:
• Cut a 25,4 cm X 25,4 cm hole through the wall.
• Position the firestops on both sides of the hole previously
cut and secure the firestops with nails or screws.
• The pipe opening of the firestops
MUST BE
placed
towards the bottom of the firestop.
• Continue the flue run through the firestop.

E. Install Support Brackets
For Horizontal Runs -
The flue system must be supported
every five (5) feet (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 eight feet (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 22,9 cm x 22,9 cm hole through the ceiling 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.
