d. Installing the Interior Wall Shield (WS6)
Frame a hole in a combustible wall for an interior
wall shield, as shown in Figure 10, whenever a
wall is penetrated. This shield maintains
minimum clearances and prevents cold air
infiltration.
Secure the wall shield to the framing as shown
in Figures 11-12.
The termination cap height must meet all local
and national codes and not be easily blocked
or obstructed.
If the hole being penetrated is of
noncombustible materials, a 9 diameter hole
is acceptable.
Note:
Exterior wall thickness must be a minimum of
4 to a maximum of 23 1/2.
