ANGLED WALL RADIATION SHIELD
(RSM+, RSMI30, RSMI45)
When traversing a combustible wall with the chimney at a 30° or 45°
angle, an angled firestop and/or wall radiation shield must be installed.
Only one is required (Figure 27). Table 6 gives recommended hole size
for installing a wall radiation shield.
Note: 45° angle installation for Canada only.
In cold climate locations (climates where temperatures will fall below
32° F / 0° C), we recommend that you use the insulated wall radiation
shield since it will maintain the home’s thermal barrier.
