ChIMNEY PIPE
The DESA Heating, LLC chimney system is
a snap-lock, double-wall pipe. It consists of a
stainless steel inner flue 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 measurable length of a part
after two or more parts are connected.

PIPE INSTALLATION

The pipe sections must be assembled indepen-
dently as the chimney is installed. When connect-
ing chimney directly to the firebox, the inner flue

pipe section must be installed first with the lanced
side up. The outer pipe section can then be in-
stalled over the flue pipe section with the hemmed
end up. Press down on each pipe section until the
lances securely engage the hem on the firebox
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 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.
