INSTALLATION
INSTALL THE CHIMNEY SYSTEM
Start by attaching the first chimney section to the collar
on top of the fireplace.
Install the pipe as pictured in Figure 16. When you get
a good lock, you will hear the pipe clearly snap together.
Once sections are snap-locked in place, it is extremely
difficult to get them apart.
Make sure the pipe is firmly
snapped and locked together as each pipe section is
mounted.
When installing elbows, only outer pipe will snap- lock.
Middle pipes simply slide into position. Be sure to always
attach straps on upper elbow to a structural framing
member. (Fig. 17)
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer. Refer to Figure 18 for appropri-
ate spacer orientation.

INSTALL 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 12 for angled firestop 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 flooring
material exceeds 8" (203 mm), adjustments must be
made in framing to assure that minimum air spaces to
chimney are maintained.
PROPER FIRESTOP SPACER INSTALLA-
TION
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.
CONTINUE INSTALLING PIPE TO COM-
PLETE RUN
Continue attaching pipe sections to complete system
to next level always being careful that the pipe is firmly
snapped locked in place before proceeding to next pipe
section.
