Figure 27. Ceiling Firestop (Ceiling Side)
If the area above the ceiling IS an attic, position and
secure the firestop on top of the previously framed hole.
C. Flue Termination
For Horizontal Terminations using the DVP-TRAP
To attach and secure the termination to the last section
of horizontal flue:
• The rear flue heat shield MUST be placed one inch
above the top of the flue between the wall shield and
the base of the termination cap.
• One section of the heat shield is attached to the
wall shield. The other is attached to the termination
cap in the same manner (see Figure 29).

• The termination kit should pass through the wall
firestops from the exterior of the building.
• Adjust the termination cap to its final exterior posi-
tion 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.
If the area above the ceiling is NOT an attic, position
and secure the ceiling firestop on the ceiling side of
the previously cut and framed hole.
Figure 29. Venting through the Wall
• The heat shield sections will overlap to match the
wall thickness (depth).
• If the wall thickness does not allow the required 1-1/2
inch heat shield overlap, an extended heat shield
must be used. The extended heat shield will need
to be cut to the thickness of the wall and be at-
tached to the wall shield.
• The small leg in the shield rests on top of the flue to
properly space it from the pipe section (see Figure
29).
