Note:
When using termination caps with factory-supplied
heat shield attached, no additional wall shield firestop is
required on the exterior side of a combustible wall.
L. Install Horizontal Termination Cap
WARNING! Risk of Fire!
The telescoping flue section
of the termination cap MUST be used when connecting
vent.
• 1-1/2 (38 mm) minimum overlap of flue telescoping
section is required.
Failure to maintain overlap may cause overheating and
fire.
• When installing a horizontal termination cap, follow
the cap location guidelines as prescribed by current
ANSI Z223.1
and
CAN/CGA-B149
installation codes
and refer to Section 6 of this manual.
CAUTION! Risk of Burns!
Local codes may require
installation of a cap shield to prevent anything or anyone
from touching the hot cap.
NOTICE:
For certain exposures which require superior
resistance to wind-driven rain penetration, a flashing kit and
HRC caps are available. When penetrating a brick wall, a
brick extension kit is available for framing the brick.
