G. Install Firestops
For Horizontal Runs -
Firestops are
REQUIRED
on both
sides of a combustible wall through which the fl ue passes.
To install fi restops (heat shield) for horizontal runs that pass
through either interior or exterior walls:
• Cut a 10 inch by 12 inch (254 mm X 305 mm) hole
through the wall.
• Position the fi restops on both sides of the hole previously
cut and secure the fi restops with nails or screws.
• The pipe opening of the fi restops
MUST BE
placed
towards the bottom of the fi restop.
• Continue the fl ue run through the fi restop.

F. Install Support Brackets
For Horizontal Runs -
The fl ue system must be supported
every fi ve (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 fl ue pipe.
• Nail the pipe supports to the framing members.
For Vertical Runs -
The fl ue system must be supported
every eight feet (2.44 m) above the heater fl ue outlet by
wall brackets. To install support brackets for vertical runs:
• Attach wall brackets to the fl ue pipe and secure the wall
bracket to the framing members with nails or screws.
For Vertical Runs -
One fi restop is
REQUIRED
at the hole
in each ceiling through which the fl ue passes.
To install fi restops for vertical runs that pass through
ceilings:
• Position a plumb bob directly over the center of the
vertical fl ue component.
• Mark the ceiling to establish the centerpoint of the fl ue.
• Drill a hole or drive a nail through this center point.
• Check the fl oor above for any obstructions, such as
wiring or plumbing runs.
• Reposition the heater and fl ue system, if necessary, to
accommodate the ceiling joists and/or obstructions.
• Cut a 254 mm X 254 mm hole through the ceiling when
using DVP pipe, and a 229 mm x 229 mm hole when
using SLP pipe. Use the fi restop pipe opening as a
guide.
• Frame the hole with framing lumber the same size as
the ceiling joists.
