• Overlap pipe slip sections at least
1-1/2 in. (38 mm).
• Use pilot holes for screws.

joined.

• Maintain a 1-1/2 in. (38 mm) minimum
overlap on telescoping

WARNING
Install the Horizontal Termination Cap
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.
Heat Shield Requirements for Horizontal Termination
For all horizontally vented appliances, a heat shield MUST
be placed 1 in. (25 mm) above the top of the vent between
the wall shield
fi
restop and the base of the termination cap.
There are two sections of the standard heat shield. One sec-
tion is factory-attached to the wall shield
fi
restop. The other
section is factory-attached to the cap. See Figure 3.1.
If the wall thickness does not allow the required 1-1/2 in.
(38 mm) heat shield overlap when installed, an extended
heat shield must be used.
The extended heat shield may need to be cut to length. You
will attach the cut heat shield to the existing cap heat shield
or wall shield
fi
restop heat shield (refer to Figure 3.1) using
the supplied screws. You MUST maintain a 1-1/2 in. (38 mm)
overlap of the extended heat shield and the existing shields
(both ends of the heat shield). The small leg on the extended
heat shield should rest on the top of the vent (pipe section)
to properly space it from the pipe section.
Imporant Notice
: Heat shields may NOT be field
constructed.
