3) Tighten the worm band clamp screw to secure PVC
to PP boiler adapter.
4) Do not install PVC to PP boiler 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.
5)
APX800 model
- Apply a coating of supplied red
RTV silicon sealant, at least 1” wide, to PVC to PP
boiler adapter (6PPS-06PVCM-6PPF) male end,
when used for combustion product venting.
If polypropylene pipe is also used for combustion air
supply, application of the silicon sealant to PVC to
PP boiler adapter (6PPS-06PVCM-6PPF) male end
is not required.
6)
APX800 model
- Push and twist PVC to PP boiler
adapter (6PPS-06PVCM-6PPF) into two-pipe vent
system connector vent port or air supply port until
bottomed out.
7) Tighten the worm band clamp screw to secure PVC
to PP boiler adapter.
8) Do not install PVC to PP boiler 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.
When using
Centrotherm Eco
polypropylene pipe
for combustion product venting and/or air supply PVC
to PP boiler adapter (ISAA0404 or ISAAL0404 and
ISAA0606 or ISAAL0606 as applicable) is installed
into the two-pipe vent system connector vent or
combustion air supply port as follows (see Figure 14):
9)
APX399 and APX500 models
- Apply provided
dielectric grease (grease pouch taped to the vent
system connector) all around to the vent or air
connection inner red silicon gasket.
10)
APX399 and APX500 models
- Push and
twist PVC to PP boiler adapter (ISAA0404 or
ISAAL0404) into two-pipe vent system connector
vent connection or air supply port until bottomed
out.
11) Tighten the worm band clamp screw to secure PVC
to PP boiler adapter.
12) Do not install PVC to PP boiler 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.
13)
APX800 model
- Apply a coating of supplied red
RTV silicon sealant, at least 1” wide, to PVC to PP
boiler adapter (ISAA0606 or ISAAL0606) male
end,
when used for combustion product venting.
If polypropylene pipe is also used for combustion air
supply, application of the silicon sealant to PVC to
PP boiler adapter (ISAA0606 or ISAAL0606) male
end is not required.
14)
APX800 model
- Push and twist PVC to PP boiler
adapter (ISAA0606 or ISAAL0606) into two-pipe
vent system connector vent port or air supply port
until bottomed out.
15) Tighten the worm band clamp screw to secure PVC
to PP boiler adapter.
16) Do not install PVC to PP boiler 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.
Optional Two-pipe Vertical Venting Installation –
Running Flexible Polypropylene Vent (Liner)
Thru Unused Chimney Chase (see Figure 15).
Apex APX399 and APX500 boilers are approved for
vertical venting by installing Flexible Vent in an UNUSED
masonry chimney/chase and supplying combustion air
thru a separate wall or roof air intake terminal.
