IV. Venting C. Polypropylene Venting (continued)
g. Install the adapter connector PPS-PACL
(applicable to M& G/DuraVent vent system
only) to secure PVC to PP coupling adapter
to a coupling and a polypropylene rigid
pipe, either venting and/or air intake.
4. System Assembly
a. Plan venting system to avoid possible
contact with plumbing or electrical wires.
Start at vent connector at boiler and work
towards vent termination.
b. Follow all manufacturer instructions and
warnings when preparing pipe ends for
joining and when assembling the vent/
combustion air system.
c. Use locking band clamps at all vent pipe
joints.
a. Models ALP080B through ALP285B are
listed for vertical venting by installing
flexible vent in an UNUSED masonry
chimney/chase or B-Vent chase and
supplying combustion air through a
separate sidewall or roof combustion air
terminal.
b. Refer to Figures 16A or 16B for details of
masonry chimney chase or B-Vent chase
installation.
c. Flexible polypropylene pipe must be treated
carefully and stored at temperatures higher
than 41°F (5°C).
d. Do not bend or attempt to install flexible
pipe if it has been stored at lower ambient
temperature without allowing the pipe to
warm up to a higher temperature first.
WARNING
Asphyxiation Hazard. Vent
systems made by listed PP vent system
manufacturers rely on gaskets for proper
sealing. When these vent systems are used,
take the following precautions:
• Make sure that gasket is in position and un-
damaged in the female end of the pipe.
• Make sure that both the male and female
pipes are free of damage prior to assembly.
• Only cut vent pipe as permitted by the
vent manufacturer in accordance with their
instructions. When pipe is cut, cut end
must be square and carefully de-burred prior
to assembly.
• Use locking band clamps at all vent pipe
joints.
Asphyxiation Hazard.
Flexible polypropylene vent must be installed
only in an UNUSED chimney. A chimney, either
single or multiple flue type, is considered
UNUSED when none of the flues is being used
for any appliance venting. Where one of the
multiple flues is being used for an appliance
venting, the flexible vent installation is not
permitted through any of adjacent flues.
Asphyxiation Hazard.
Bending or attempting to install flexible pipe
if it has been stored at ambient temperature
below 41°F (5°C) will cause material to become
brittle and lead to cracks, resulting in flue gas
leaks.
Do not install flexible polypropylene pipe at
an angle greater than 45 degrees from vertical
plane when used for combustion product
venting. Failure to do so will result in improper
condensate drainage towards the boiler and
possible subsequent vent pipe blockage.
WARNING
WARNING
NOTICE The venting system must be free
to expand and contract and supported in
accordance with installation instructions
included by the listed polypropylene venting
component manufacturers, whichever
applicable. Polypropylene pipe sections must
be disengaged 1/4 to 5/8 in.
(6 mm to 16 mm) per joint to allow for thermal
expansion.
5. Running Flexible Polypropylene Vent(Liner)
Through Unused Masonry Chimney Chase or
B-Vent Chase
NOTICE Pressure drop for flexible
polypropylene liner is 20% greater than
from rigid pipe. Multiply measured flexible
polypropylene liner length by 1.2 to obtain
equivalent length. Maximum equivalent length
of flexible polypropylene liner is 48 ft. (14.6 m).
