When traversing a combustible wall with the chimney at a 30º or 45º angle, an angled firestop and / or wall radiation
shield must be installed. Only one is required.
NOTE: 45º ANGLE FOR CANADA ONLY.
In cold climate locations (such as Canada and Northern USA), we recommend that you use the insulated wall
radiation shield since it will maintain the home's thermal barrier.
