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 spac
-
ers provide minimum required air space to chimney
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 re-
quired 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 insu-
lation shield is required
to prevent attic insulation
from contacting the chim-
ney section. Framing
dimensions for the chim-
ney hole should measure
14¹⁄₂" x 14¹⁄₂" (368 x
368mm). An attic shield
MUST be installed on top
of attic joists (above the
floor level). (Fig. 19)
