ii . Install CPVC/PP/SS vent connector. Follow
instructions in “2. Field Installation of
CPVC/PP/SS Vent Connector” under “B.
CPVC/PVC Venting.”
iii. Apply provided dielectric grease to gasket
inside vent connector that will be in contact
with adapter.
iv.
Push and twist adapter into vent system
connector until adapter bottoms out.
v. Tighten clamp to secure adapter in CPVC/
PP/SS vent connector.
b. Combustion Air Connector (see Figure 18)
i. No adapter is required if using PVC
combustion air pipe. An adapter is required
for both M&G DuraVent PolyPro (see Table
17A), Centrotherm InnoFlue (see Table
17B) and Z-Flex Z-Dens (see Table 18)
combustion air pipes.
ii. Insert adapter into combustion air connector.
Adapter has gasket to seal against
combustion air connector.
3. System Assembly
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.
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.
See Figure 19 or Figure 20 for locking band
clamp installation.
nOTiCE
The venting system must be free to expand
and contract and supported in accordance
with installation instructions included by the
original 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.
4. Terminations
a. For standard horizontal sidewall terminations, see
Figures 7 and 8. For vertical roof terminations,
see Figures 10 and 11. Use UV resistant
components listed in Tables 17A, 17B and 18.
b. If using M&G duravent PolyPro pipe, install
screens per Figure 16. Remove gasket inside
termination and install screen in place of gasket.
If using Centrotherm InnoFlue or Z-Flex Z-Dens
end pipe, screen fits onto end of pipe.
c. For low profile sidewall termination, see Figure
9. Use low profile termination listed in Table 13
and adapter kit listed in Tables 17A, 17B and 18.
5. Running Flexible Polypropylene Vent
(Liner) Through Unused Chimney Chase
Warning
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.
