Universal Offset Support; Chimney Chase And Multiple Terminations - Valcourt ANTOINETTE FP7CB Installation And Operation Manual

4.7.2 Universal Offset Support

This support is used to support the chimney above an offset. When the chimney offset is used
to pass through a wall, this support may be used on the wall to support the chimney. For offset
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.

Chimney Chase and Multiple Terminations

For the purpose of this manual, a chimney chase is considered a part of the chimney system
rather than part of a building.
For installations where more than one chimney is located in the same chase or within the same
area, we suggest that their terminations be separated by at least 16" (410 mm) horizontally, and
18" (460 mm) vertically. This separation is to prevent smoke migrating from one chimney to
another (see Figure 37).
