In cold climate locations, an insulated firestop may be
installed at the ceiling level. This will minimize heat loss
around the chimney at this location.
The insulated radiation shield should be installed from

This support has three possible uses:
1.
For ASHT+ / and S-2100+ / , 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.
Table 7 gives maximum height of supported chimney.
Note: For the AC chimney, a support section must be used every 40' instead of the roof support.
