ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY
SYSTEM
Each double wall chimney section consists of a galvanized outer
pipe, a stainless steel inner 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 designated HT.
Opening in collar around chimney at top of
fireplace must not be obstructed. Never use blown
insulation to fill chimney enclosure.
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 together, 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 together
(exception - see Figure 11, page 10).
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 Figure 11/
offset chart, page 10).
Note: For systems with 2 elbow sets, minimum 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 10, details A and
B, page 8).
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 9, page 9).
4. All pipe connections between offset and return must be secured
with two screws on outer pipe only (see Figure 11, page 10). Do
not penetrate inner stainless.
