Heat Shield Requirements for Horizontal Termination
For all horizontally vented appliances, a heat shield MUST
be placed 1 in. above the top of the vent between the wall
shield and the base of the termination cap.
There are two sections of the heat shield. One section at-
taches to the wall shield with two screws. The remaining
section is attached to the cap in the same manner. See
Figure 2.16.
If the wall thickness does not allow the required 1-1/2 in.
heat shield overlap, an extended heat shield must be used.
The extended heat shield will need to be cut to the thickness
of the wall and be attached to the wall shield. The small leg
