Combustible Wall Penetration
Frame a hole in a combustible wall for an interior wall shield,
(Figure 6.2) whenever a wall is penetrated. Use same size
framing materials as those used in the wall construction.
The wall shield maintains minimum clearances and pre-
vents cold air infiltration.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by noncombus-
tible materials such as concrete, a hole with diameter one
inch greater than the pipe is acceptable.
