M. Install Horizontal Termination Cap
WARNING! Risk of Fire! The telescoping fl ue section of
the termination cap MUST be used when connecting vent.
• 1-1/2 (38 mm) minimum overlap of fl ue telescoping
section is required.
Failure to maintain overlap may cause overheating and
fi 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 fl ashing kit and
HRC caps are available. When penetrating a brick wall, a
brick extension kit is available for framing the brick.
