5.0 Installing Vent/Combustion Air & Condensate Drain
664A0100 - Rev. A
The drain line materials must be an
approved material by the authority hav-
ing jurisdiction. In absence of such
authority, PVC and CPVC piping must
comply with ASTM D1785 or D2845.
The cement and primer used on the pip-
ing must comply with ASME D2564 or
F493. For installations in Canada, use
CSA or ULC certified PVC or CPVC
pipe, fittings and cement/primer.
8. Continue the pipe from the drain assembly
to a floor drain or condensate pump.
When selecting and installing a conden-
sate pump, ensure the pump is approved
for use with condensing boilers and fur-
naces. The pump should be equipped
with an overflow switch to prevent prop-
erty damage from potential condensate
spillage.
9. The PRESTIGE Excellence will typically
produce a condensate that is considered
slightly acidic with a pH content below 3.0.
Install a neutralizing filter if required by
authority having jurisdiction.
The condensate drain must remain filled
and unobstructed and allow unrestricted
flow of condensate. The condensate
should not be subject to conditions
where freezing could occur. If the con-
densate is subjected to freezing or
becomes obstructed , it can leak, result-
ing in potential water damage to the boil-
er and surrounding area.
