Angled 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 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.

Chimney Support Installation
4.7.1 Universal Roof Support
This support has three possible uses:
1. It must be used on a roof to support the chimney.
2. It may be used on a floor, ceiling or roof above an offset to support the chimney above the
offset.
3. It may be used on a floor, ceiling or roof as a supplementary support.
For roof support installation, refer to the instructions provided with the support by the chimney
manufacturer. Many manufacturers will provide the maximum height of chimney that can be
supported by the support. Make sure you respect those parameters.
