4.10.6 Flexible Chimney Liner Venting
A masonry chimney may be used as a chase for
vertically venting the FT boiler. The parts and
instructions are available from DuraVent distributors.
Please refer to the Table 8. The vent parts used within
the chimney must all be PP Flex components and be
installed in accordance with the detailed Installation
Instructions provided with the parts. Those instructions
are for the installation of the vent from the top of the
chimney (including the Termination) to a point at the
bottom of the chimney. From this point, use single wall
PP pipe to connect to the exhaust connection on the
boiler.
For FT Boilers replacing boilers utilizing B Vent
chimneys, parts are also available to use the existing
B Vent chimney as a chase for the PP Flex. As with
the masonry chimney, the PP Flex is only used within
the chimney and must be connected to rigid PP pipe
from that point to the exhaust connection of the FT
Boiler. Three (3) 90 degree elbows and up to 15 ft feet
of rigid 3" PP pipe are allowed.
3" rigid PP pipe is required from the bottom of the PP
Flex liner to the exhaust connection of the FT Boiler.
The maximum allowable length of PP Flex pipe is 50
feet of three (3) inch diameter Flex pipe.
