Installing 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 13. 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.

Install pipe, listening for the snap-lock to fasten.
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 mem-
ber. (Fig. 14)
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 10 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 Installation
Figure 15 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.
