C. Installing Heat Shield and Horizontal Termination Cap
NOTE: Where required, an exterior wall ashing is
available.
When penetrating a brick wall, a brick extension kit
is available for framing the brick.
Heat Shield Requirements for Horizontal Termination
For all horizontally vented appliances, a heat shield MUST
be placed one inch above the top of the vent between the
wall shield restop and the base of the termination cap.
There are two sections of the heat shield. One section attach-
es to the wall shield restop with two screws. The remaining
section is attached to the cap in the same manner.
If the wall thickness does not allow the required 1-1/2
inch heat shield overlap, an extended heat shield must
be used.
The extended heat shield will need to be cut to the thick-
ness of the wall and be attached to the wall shield restop.
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 (see Figure 8.12).
Installing 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.
