4.4 ANGLED WALL RADIATION SHIELD
(RSM+, RSMI30, RSMI45)
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.
Note: 45º angle for Canada only
In cold climate locations, we recommend that you use the insulated wall radiation shield
since it will maintain the home’s thermal barrier.
