For Vertical Runs
The fl ue system must be supported every 2.4 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.

4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on
both sides of a combustible wall through which the
fl ue passes.
Frame a hole in a combustible wall for an interior wall
shield fi restop, whenever a wall is penetrated. Use
same size framing materials as those used in the wall
construction. The wall shield fi restop maintains mini-
mum clearances and prevents cold air infi ltration. a
wall shied fi restop must be placed on each side of an
interior wall. A minimum 38 mm overlap of attached
heat shield must be maintained. See Figure 35.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by non-
combustible materials such as concrete, a hole with
diameter 25.4 mm greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the
wall shield fi restop is only required on one side and no
heat shield is necessary.

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 obstruc-
tions.
• 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.
