4.5CHIMNEY SUPPORT INSTALLATION

Universal Roof Support

This support has two possible uses:

1.It may be used on a floor, ceiling or roof above an offset to support the chimney above the offset.

2.It may be used on a floor, ceiling or roof as a supplementary support

Table 6 gives maximum height of supported chimney.

NOTE: For the AC chimney, a support section may be used every 40 ft. (12 m) instead of the universal roof support (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.

4.6CHIMNEY 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 28).
