A restop spacer is used to keep pipe spaced properly
and required for safety.
Nail the restop spacer (at each corner) to the framing
members of the ceiling hole.  A restop spacer
is not required at the roof.
Hole sizes listed in Figure 9 for angled restop spacers
provide minimum required air space to chimney pipe for
ceiling thickness up to 8” (203 mm). When combined
thickness of ceiling material, ceiling joists and ooring
material exceeds 8” (203 mm), adjustments must be
made in framing to assure that minimum air spaces to
chimney are maintained.

Figure 18 shows different installation procedures for
both an area that is an attic and an area that is not an
attic.
If the area above the ceilingan attic, position the
restop spacer with the ange on the ceiling side and
the angled portion extending up into the hole.
If the area above the ceiling  an attic, position the
restop spacer with the ange on the top of the framed
hole and the angled portion extending down into the
hole.

In Canada, an attic insulation shield is required to
prevent attic insulaiton from contacxting the chimney
section.  If the attic insulation shield is used, the
restop is not required in the attic installation. Framing
dimensions fr the chimney hole should measure 17¹⁄₂” x
17¹⁄₂” (445 x 445 mm). An attic shield MUST be installed
on top of attic joists (above the oor level). (Fig. 19)
 In the U.S., it is a good idea, although not al-
ways required, to install an attic insulation shield where
blown-in insulation is planned to be used in the atic.

If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to adja-
cent structural framing, as shown on Figure 16. Bend
straps as necessary and make sure they are secure so
they will support the weight of the chimney. A chimney
support is 2¹⁄₂" (64 mm) long when installed. Consider
this dimension when determining how many straight
chimney sections are needed.
 Chimney supports are generally used in long
runs in a chase installation.
