• Adjust the termination cap to its final exterior position
on the building and interlock the flue sections.
WARNING: THE TERMINATION CAP MUST

BE POSITIONED SO THAT THE ARROW IS
POINTING UP.
• Use a high-temperature sealant gasket to seal be-
tween the pipe and exterior firestop.

Figure 30. Termination Cap
For Vertical Terminations - To locate the flue and
install the flue sections:
• Locate and mark the flue center point on the under-
side of the roof, and drive a nail through the center
point.
• Make the outline of the roof hole around the center
point nail.
• The size of the roof hole framing dimensions depend
on the pitch of the roof. There MUST BE a 1 in. (25
mm) clearance from the vertical flue pipe to combus-
tible materials.
• Mark the roof hole accordingly.
• Cover the opening of the installed flue pipes.
• Cut and frame the roof hole.
• Use framing lumber the same size as the roof rafters
and install the frame securely. Flashing anchored to
the frame must withstand heavy winds.
• Continue to install concentric flue sections up through
the roof hole and up past the roof line until you reach
the appropriate distance above the roof.

NOTE: This also pertains to vertical flue systems in-
stalled on the outside of the building.
To seal the roof hole, and to divert rain and snow from
the flue system:
• Attach a flashing to the roof using nails, and use a
non-hardening flexible joint sealant around the edges
of the flashing base where it meets the roof.
• Attach a storm collar over the flashing joint to form
a water-tight seal. Place non-hardening flexible joint
sealant around the joint, between the storm collar
and the vertical pipe.
• Slide the termination cap over the end of the flue
pipe and snap into place.
NOTICE: Failure to properly caulk the roof flashing and
pipe seams may permit entry of water.
• Caulk the gap between the roof flashing and the
outside diameter of the pipe.
• Caulk the perimeter of the flashing where it contacts
the roof surface. See Figure 31.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
