IV. Venting C. Polypropylene Venting (continued)
1) Remove external worm band clamp from upper
vent connection port of the two-pipe vent system
connector.
2) Using needle nose pliers grasp one of three spot
welded band clamp straps, close to a spot weld, and
reverse bend towards vent system connector body.
3) Repeat the same with two remaining clamp straps.
4) Apply provided dielectric grease (grease pouch
taped to the vent system connector) all around to
the vent connection inner red silicon gasket.
5) Lubricate PVC to PP boiler adapter (3PPS-AD or
4PPS-AD as applicable) outer seal with water, than,
push and twist the adapter into the vent connection
port until bottomed out.

6) Install boiler adapter connector PPS-PAC to secure
PVC to PP boiler adapter to the vent connection
port of boiler two-pipe system connector.
7) Attach modied two-pipe system adapter to boiler.
See Figure 5 for details.
8) Lubricate PVC to PP boiler adapter inner seal with
water, than, push and twist a rigid PP pipe male
end into PVC to PP boiler adapter female end until
bottomed out.
9) When also using M&G/DuraVent polypropylene
pipe for combustion air supply to boiler repeat the
step 1 to modify the lower combustion air supply
port of the vent system connector to accept PVC
to PP boiler adapter.
10) Do not modify the lower combustion air supply port
of the two-pipe vent system connector when using
PVC pipe for combustion air supply to boiler.
When using Centrotherm Eco polypropylene pipe for
combustion product venting and/or air supply PVC to PP
boiler adapter (ISAA0303 or ISAA0404 as applicable) is
installed into the two-pipe vent system connector vent or
combustion air supply port as follows:
