NOTE: This illustration is not to scale. It represents how the chimney
must be supported. A 30 degree offset only is allowed in the USA
and a 45 degree maximum offset is allowed in Canada.
NOTE: In cold areas it is recommended 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.
