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 fi restop and the base of the termination cap.
There are two sections of the heat shield. One section
is factory-attached to the wall shield fi restop. The other
section is factory-attached to the cap. See Figure 8.12.
If the wall thickness does not allow the required 1-1/2 inch
(38mm) heat shield overlap when installed, an extended
heat shield (DVP-HSM-B) must be used.
Important Notice: Heat shields may not be fi eld constructed.
The extended heat shield (DVP-HSM-B) 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 8.12) 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.
