CHIMNEY SUPPORT INSTALLATION
Universal Roof Support
This support has three possible uses:
1. For ASHT+ * / *, S-2100+ * / * and DuraTech ® DTC**,
it must be used on a roof to support the chimney.
2. It may be used on a fl oor, ceiling or roof above an offset to support
the chimney above the offset.
3. It may be used on a fl oor, ceiling or roof as a supplementary sup-
port.
Table 6 gives maximum height of supported chimney.
NOTE : For the AC * chimney, a support section must be used every forty
(40) feet (12 m) instead of the universal roof support (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 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) verti-
cally. This separation is to prevent smoke migrating from one chimney
to another (see
Figure 31 ).

CHIMNEY ADAPTOR * (S-2100+ / ) CANADA ONLY
The fi replace is normally supplied with a chimney adaptor suitable for
the ASHT+
* / * chimney. If you want to install a S-2100+ *
/ * chimney, an adaptor is available (6UCA * ) ( Figure 32 ) . A
separate starter section will also be required if AC * chimney is installed.
