M. Install Horizontal Termination Cap
WARNING! Risk of Fire! The telescoping ue section of
the termination cap MUST be used when connecting vent.
• 1-1/2 (38 mm) minimum overlap of ue telescoping
section is required.
Failure to maintain overlap may cause overheating and
re.
Vent termination must not be recessed in the wall. Siding
may be brought to the edge of the cap base.
• Flash and seal as appropriate for siding material at
outside edges of cap.
• 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 in-
stallation 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 ashing kit and
HRC caps are available. When penetrating a brick wall, a
brick extension kit is available for framing the brick.
