Angled Wall Radiation Shield - Lennox BRENTWOOD SP Installation And Operation Instructions Manual

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°
F / 0° C), we recommend that you use the insulated wall radiation shield
since it will maintain the home's thermal barrier.
