fireplace must not be obstructed.
Never use blown insulation to fill
chimney enclosure.
ASSEMBLY AND INSTALLATION OF
DOUBLE WALL CHIMNEY SYSTEM
Each double wall chimney section consists of
a galvanized outer pipe, a stainless steel in-
ner flue pipe and a wire spacer. Pipe sections
must be assembled independently as chimney
is installed. When connecting chimney directly
to fireplace, inner flue pipe section must be
installed first with lanced side up. Outer pipe
section can then be installed over flue pipe
section with hemmed end up. Press down
on each pipe section until lances securely
engage hem on fireplace starter. Wire will
assure proper spacing between inner and
outer pipe sections.
Note: For Canada, use chimney parts des-
ignated HT.
Opening in collar around
chimney at top of fireplace must
not be obstructed. Never use
blown insulation to fill chimney
enclosure.

Continued
Continue to assemble chimney sections as
outlined, making sure that both inner and
outer pipe sections are locked together. When
installing double wall snap-lock chimney to-
gether, it is important to assure joint between
chimney sections is locked. Check by pulling
chimney upward after locking. Chimney will
not come apart if properly locked. It is not
necessary to add screws to keep chimney to-
gether (exception - see Figure 12, page 9).
USING ELBOW OFFSETS (30E-8DM)
1. To achieve desired offset, you may install
combinations of 12", 18", 24", 36" and 48"
length of double wall pipe (see offset chart
and Figure 10).
Note: For systems with 2 elbow sets, mini-
mum height is 22 feet. Maximum height
for any system is 50 feet.
2. Chimney weight above offset rests on
return elbow. Straps must be securely
nailed to rafters or joists (see Figure 11,
details A and B on page 9).
3. Maximum length of pipe between supports
(return elbow or 12S-8DM) is 6' of angle
run. Maximum of two 6' angle run sections
per chimney system (see Figure 10).
4. All pipe connections between offset and
return must be secured with two screws
on outer pipe only (see Figure 12, page
9). Do not penetrate inner stainless.
