ANGLED WALL RADIATION SHIELD
When passing through a combustible wall with the chimney at a 30
°
or 45
°
angle (30
°
or 45
°
in Canada and
30
°
only in the USA), an angled firestop or wall radiation shield provided by the chimney manufacturer
must be installed. Only one is required. Follow the chimney manufacturer’s installation instructions.
In cold climate locations, it is recommended that you use the insulated wall radiation shield since it will
maintain the home’s thermal barrier.
