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. The termination must be placed a minimum of 18" (460 mm) above
the chase.
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 44).
