IV. Venting C. Polypropylene Venting (continued)
1. Components
a. Listed polypropylene vent system manufacturers
are shown in Table 8. It is the responsibility of
the installing contractor to procure polypropylene
vent system pipe and related components.
i. All listed polypropylene vent system
manufacturers comply with the requirements
of ULC-S636-08 ‘Standard for Type BH
Gas Venting Systems’.
ii. Centrotherm Eco Systems InnoFlue SW
Rigid Vent and Flex Flexible Vent comply
with the requirements of UL 1738 ‘Standard
for Safety for Venting Systems’.
b. See Table 9A for specic M&G Duravent
components.
c. See Table 9B for specic Centrotherm Eco
Systems components.
d. See Table 9C for specic Z-Flex Z-Dens™
components.
e. See Table 9D for specic Selkirk Polyue
components.
2. Field Installation of CPVC/PVC Two-
Pipe Vent System Connector and PVC to
Polypropylene Adapter - Floor Mounted
Builds
a. Install CPVC/PVC two-pipe vent system
connector. Follow instructions in “2. Field
Installation of CPVC/PVC Two-Pipe Vent
System Connector” under “B. CPVC/PVC
Venting.” See Figures 9 and 14.
b. Models ALP080BF through ALP210BF (oor
mounted) and ALP285B only: Apply provided
dielectric grease (grease pouch taped to the vent
system connector) all around to the vent or air
connection inner red silicon gasket.
c. Push and twist boiler male adapter, PVC to PP,
into two-pipe vent system connector vent port
until bottomed out.
d. Tighten the worm band clamp screw to secure
male PVC to PP adapter.
e. Do not install PVC to PP adapter at the lower
combustion air supply port of the two-pipe vent
system connector when using PVC pipe for
combustion air supply to boiler.
3. Alpine Boiler Two-Pipe Vent System
Field Installation Procedure to Accept
Polypropylene Vent Piping - Wall Mounted
Boiler Builds
Alpine wall mounted boiler builds have a factory
installed vent connector 90° elbow inside air box and
air box top located combustion air collar.
Wall hung boilers having 3” vent connection 90°
elbow inside air box (ALP080, ALP105, ALP150 and
ALP210) can accept Z-Flex Z-Dens™ extended boiler
male adapter, PVC to PP (part number 2ZDCPVCG3L,
see Table 9C) followed by the balance of Z-Flex
Z-Dens™ polypropylene vent piping including vent
termination. Using of factory provided 30” CPVC
pipe and 90° CPVC elbow is not required if Z-Flex
Z-Dens™ polypropylene vent system is used.
No other polypropylene vent system manufacturer -
M&G/DuraVent (Polypro), Centrotherm (Eco) and
Selkirk (Polyue) - offers such extended boiler male
adapter at this instruction release time.
To accept polypropylene piping manufactured by
M&G/DuraVent (Polypro), Centrotherm (Eco) and
Selkirk (Polyue) for venting and/or combustion air
(see Figure 15 “Field Installation Procedure to accept
Polypropylene Vent Piping - Wall Mounted Boiler”):
a. Install supplied 30 in. long CPVC pipe into a
factory installed vent connector 90° elbow and
secure with the elbow band clamp.
b. When using polypropylene pipe for combustion
air intake, install a 4 in. long stub of an
appropriate diameter PVC air intake pipe
(contractor supplied) onto air box top located
combustion air collar. Seal the stub to air box
top with silicon all around.
c. Attach and cement an appropriate diameter
CPVC coupling (contractor supplied) to
previously installed 30 in. long CPVC pipe
exposed end.
d. If using polypropylene pipe for combustion
air intake, attach and cement an appropriate
diameter PVC coupling (contractor supplied) to
exposed end of PVC air intake stub.
e. Lubricate CPVC coupling adapter, PVC to PP,
(see Tables 9A thru 9C as applicable) outer seal
with water (or approved water based lubricant),
then insert and push lubricated adapter end into
CPVC coupling open end until bottomed out.
f. If using polypropylene pipe for combustion air
intake, repeat the above step installing the PVC
to PP coupling adapter into PVC air intake.
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.
