CHIMNEY CHASE AND MULTIPLE TERMINA-
TIONS
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 migration from one chimney
to another (see Figure 29).
CHIMNEY ADAPTOR (S2100+)
The fireplace is normally supplied with a chimney
adaptor suitable for the ASHT+ chimney. If you
want to install a S2100+ chimney, an adaptor is
availible (7UCA) (see Figure 30). If installing
ACBI, adaptor H3805 (ACBISB) or offset adaptor
H3806 (ACBISB30) is required.

CHIMNEY SUPPORT INSTALLATION
Universal Roof Support
This support has two possible uses:
1. For ASHT+ 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
above as a supplementary support when
the chimney height exceeds 15 feet (4.6
m).
Table 6
gives maximum height of supported
chimney.
Figure 30
NOTE: For the ACBI chimney, a universal sec-
tion must be used every 20 feet (6 m) instead
of the universal roof support (ST).
For roof support installation, refer to the instruc-
tions provided with the support.
Universal Offset Support
This support is used to support the chimney
above an offset. Or it may be used on the wall
to support the chimney. The maximum heights
are given in Table 6. For offset support instal-
lation, refer to the instructions provided with
the support.
