The FMI PRODUCTS, LLC chimney system is
a snap-lock, double-wall pipe. It consists of a
VWDLQOHVVVWHHOLQQHUÀXHSLSHVDJDOYDQL]HG
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 measurable length of a part
after two or more parts are connected.

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 together
(see Figure 13). 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 locking. The chimney will not come apart
if properly locked. It is not necessary to add
screws to keep the chimney together.
