UNIVERSAL ROOF SUPPORT INSTALLATION

This support has three possible uses:
1. For ASHT+ and S-2100+ chimneys, 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 feet (4.6 m.).
Table 7 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section (AC8SL) must be used every 40' (12 m) instead
of the ST.
For roof support installation, refer to the instructions provided with the support.
UNIVERSAL OFFSET SUPPORT INSTALLATION
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 7. 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" (460mm)
above the chase.
For installation where more than one chimney
is located in the same chase or within the same
general area, we suggest that their termina-
tions be separated by at least 16" (410mm)
horizontally and 18" (460mm) vertically. This
separation is to prevent smoke migrating from
one chimney to another (see Figure 23).
