The pipe sections must be assembled inde-
pendently as the chimney is installed. When
connecting chimney directly to the replace,
the inner ue pipe section must be installed rst
with the lanced side up. The outer pipe section
can then be installed over the ue pipe section
with the hemmed end up. Press down on each
pipe section until the lances securely engage
the hem on the replace starter. The wire will
assure the proper spacing between the inner
and outer pipe sections.
Continue to assemble chimney sections as
outlined above, making sure that both the
inner and outer pipe sections are locked to-
gether. When installing double wall snap-lock
chimney together, it is important to assure the
joint between the chimney sections is locked.
Check by pulling chimney upward after lock-
ing. The chimney will not come apart if prop-
erly locked. It is not necessary to add screws
to keep the chimney together (exception, see
Figure 17, page 8).

The FMI PRODUCTS, LLC chimney is a
snap-lock, double-wall pipe. It consists of a
stainless steel inner ue pipe(s), a galvanized
outer pipe and a wire spacer.
Each section of pipe comes in lengths of 12",
18" 36" and 48". The actual lineal gain for
each is measured after each section is fully
connected. Lineal gain is the actual measur-
able length of a part after two or more parts
are connected.
VENTING INSTALLATION
Continued
Chimney weight above offset rests on return
elbow. Straps must be securely nailed to raf-
ters or joists (see Figure 15, page 8).
To achieve desired offset, you may install
combinations of 12", 18", 36" and 48" length
of double wall pipe (see offset chart and
Figure 16, page 8).
The chimney support section is a 4" strap
and 12" length of pipe. A chimney support is
required every 30 feet above replace after a
straight chimney run or above a return elbow
after a straight chimney run (see Figure 17,
page 8). This support is designed to relieve
the extra weight load on replace and elbows
when high chimneys are installed.
