Universal Roof Support

When installing a support, slightly lift the chimney system so the weight

will lie on the support, not on the fireplace to reduce expansion noises.

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 sup-

port.

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

on the wall to support the chimney. The maximum heights are given in

Table 6. For offset support installation, refer to the instructions provided

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 32).
