OFFSET CHIMNEY INSTALLATION WITH WALL PENETRATION

NOTE: In cold areas it is recom-
mended to protect the chimney
in a insulated chase.
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.
NOTE: 45º angle for Canada only (
RSMI45
*
/ 6DTC-S45
**
)
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.
