CHIMNEY PIPE
WARNING: Label part number 900599-01 must
be applied by the installer to all chimney pipe
sections but is not required on sections that will
be visible after the installation is complete. Label
must wrap around the circumference of the pipe.
See accessories, page 20 for Kit F2659.
The IHP 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 fitting 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".
ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY
SYSTEM
SS-8DM starter section must be installed first.
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 the chimney is installed. When con-
necting chimney directly to the fireplace, the inner flue pipe section
must be installed first with the lanced side up. The outer pipe section
can then be installed 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 fireplace starter. The wire will assure the proper spac-
ing between the inner and outer pipe sections.
Note:
For Canada, use chimney parts designated HT.
Continue to assemble chimney sections as outlined, making sure
that both the inner and outer pipe sections are locked together. 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 (exception - see Figure 9, page 9).
The height of a vertical chimney pipe supported
ONLY
by the
fireplace, must not exceed 20 feet. Chimney heights above 20 feet
must be supported.
WARNING: The opening in collar around chimney
at top of fireplace must not be obstructed. Never use
blown insulation to fill chimney enclosure.
