INTERIOR RESUPPORT

The interior resupport is comprised of a support band with

attached straps. The interior resupport part may be used for

all sizes of chimney.

The Model TLC interior resupport allows for two different

methods of chimney resupport.

The first method is used when an immediate section of

chimney above the upper offset passes through a joist area.

With the appropriate firestop/joist shield in place, clamp the

interior resupport support band around the chimney, using two

¼” x ½” long carriage bolts and two ½” x 2” long carriage bolts

and hex nuts. Attach support band to the pipe with six sheet

metal screws as shown in Figure 6.

The interior resupport straps are then nailed to the framing

joists with at least two 8 penny nails per strap. The maximum

length of chimney that may be supported is 18 feet, which

includes the offset lengths below, any vertical run to the

resupport, and the vertical run above the interior resupport.

It does not include the length below the lower elbow/offset,

which is supported from below (Figure 6).

The second means of support is used primarily when the

immediate sections of the upper offset do not pass through a

joist area and resupport is necessary. The band is clamped

around the chimney, using two ¼” x ½” long carriage bolts

and two ¼” x 2” long carriage bolts and hex nuts. Install

band immediately below a locking band, and the straps are

nailed to the framing with at least two 8 penny nails per strap

(see Figure 7). Observe the 2” airspace minimum clearance

between the chimney and framing. The same 18-foot limit of

supportable chimney length applies to this resupport method.
