C. Flue Termination
For Horizontal Terminations -
To attach and secure
the termination to the last section of horizontal flue:
• Rotate and interlock the ends as described at the
beginning of the Installing Flue 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 flue 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 flue pipe and exterior
firestop.
