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.
