ANGLED WALL RADIATION SHIELD
When traversing a combustible wall with the chimney at a 30º or 45º
angle, an angled firestop or wall radiation shield must be installed. Only
one is required.

In cold climate locations (climates where temperatures will fall below 32°

since it will maintain the home's thermal barrier.
