SR/SC Series "A" Woodburning Fireplace
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.
Installing the Firestop Spacer
in the Ceiling Hole
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer (at each corner) to the framing
members of the ceiling hole. NOTE: A firestop spacer
is not required at the roof.
Hole sizes listed in Figure 13 for angled firestop
spacers provide minimum required air space to chim-
ney pipe for ceiling thickness up to 8" (203mm). When
combined thickness of ceiling material, ceiling joists
and flooring material exceeds 8" (203mm), adjustments
must be made in framing to assure that minimum air
spaces to chimney are maintained.
Proper Firestop Spacer Installation
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 is not an attic, position the
firestop spacer with the flange on the ceiling side and
the angled portion extending up into the hole.
If the area above the ceiling is an attic, position the
firestop spacer with the flange on the top of the framed
hole and the angled portion extending down into the
hole.
Firestop spacers are not available for nor are they
required on vertical walls.
DO NOT put any sealant around the area where the
outer pipe slides through the firestop spacer. If you
seal this area, it may cause a fire hazard.
Canadian Requirements
for Insulation Shield
In Canada, an attic
insulation shield is
required to prevent attic
insulation from contact-
ing the chimney sec-
tion. Framing dimen-
sions for the chimney
hole should measure
14 " x 14 " (368 x
368mm). An attic shield
MUST be installed on
top of attic joists (above
the floor level). (Fig.
