POWER 'VT®WATER HEATER
CONDENSATE NEUTRALIZATION
&
DISPOSAL
The
POWER
~
water
heaters
produce
significant amounts of condensate because of
their high efficiency. Condensate occurs naturally
when water vapor in combustion gases is cooled
below the dew point. Although only slightly acidic,
POWER ~ condensate can be routed through
an optional neutralization system to become pH
neutral allowing for disposal into any drain or
sewer system without concern for corrosion. A
fitting should be provided in the venting to route
any vent condensate away from the corr,bustion
blower. This can be accomplished by
ins~alling
a
tee in the vent not more than 18" from the
combustion blower outlet.
Crushed
limestone
fills
the
condensate
neutralization bath,
Condensate slowly flows
through the limestone bed and is neutralized thus
avoiding chemical treatment or dilution using
substantial
quantities
of tap
water.
If the
condensate pH is lower than 4 when checked with
a pH meter or pH paper, consult the factory for
replacement
treatment
system.
Condensate
drainage from the POWER
~
will only occur
after a recovery run cycle. If no condensate is
drained during this time, the drainpipe should be
inspected for blockage. Should the heater not be
installed on a housekeeping pad to ensure gravity
drainage, a means of removing condensate, such
as a pump, should be supplied in the system.
