CHIMNEY SUPPORT INSTALLATION
Universal roof support
This support has three possible uses :
1.
For ASHT+/ and S2100+/, 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 when the chimney height exceeds 15 ft.
(4.6 m.).
Table 6 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section must be used every 40 ft. (12 m) instead of the
ST.
For roof support installation, refer to the instructions provided with the support.
Universal offset support
This support is used to support the chimney above an offset. When the chimney offset is used
to traverse a wall this support may be used on the wall to support the chimney. The maximum
heights are given in Table 6. For offset support installation, refer to the instructions provided
with the support.

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 34).
