Each double wall chimney section consists of a
galvanized outer pipe, a stainless steel inner ue
pipe and a wire spacer. The pipe sections must be as-
sembled independently 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 re-
place 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. When install-
ing 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 (exception,
see Figure 9, page 10).

The installation of an outside air kit should be per-
formed during the rough framing of the replace
due to the nature of it's location. Outside combus-
tion air is accessed through a vented crawl space
(AK4F) or through a sidewall (AK4).

The DESA chimney system consists of 12", 18",
24", 36"' and 48" snap-lock, double-wall pipe
segments, planned for maximum adaptability
to individual site requirements. Actual lengths
gained after tting overlaps must be taken into
consideration (lineal gain) and are given in the
lineal gain chart (see Figure 6). Lineal Gain is the
actual measurable length of a part after two or more
parts are connected. For Canada, use chimney parts
designated "HT".
