C. Vent Termination
For Horizontal Terminations -
To attach and secure
the termination to the last section of horizontal vent:
Rotate and interlock the ends as described at the
beginning of the Installing Vent Components sec-
tion.
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.
WARNING
THE TERMINATION CAP MUST BE
POSITIONED SO THAT THE ARROW IS
POINTING UP.
For roundcap termination kits:
Use the exterior pipelock hole provided on the round
flange of the wall firestop to secure the vent pipe in
place.
For trapezoidal cap termination kits:
Using screws, secure the cap to the exterior wall
through the flanges built into the cap.
Use a high-temperature sealant or fiberglass rope
gasket to seal between the vent pipe and exterior
firestop.
