SECTION 6 Condensate Drain Trap
This appliance creates condensation as a by-product
of high combustion e
ciency. The condensate must
be drained from unit and from the vent system.
A combination condensate drain trap is included with
the unit for on-site assembly. This condensate drain
trap must be installed to prevent the accumulation of
condensate. Connect a ¾” PVC pipe between the
drain connection and a oor drain. The PVC pipe must
continuously slope downward toward the drain, with no
spiraling. If there is no accessible oor drain, or if the
drain pipe cannot be installed with the proper slope,
a condensate pump will be needed to ensure that the
condensate is removed.
The condensate that forms in the vent pipe should also
be drained to help prevent excessive condensate from
entering the unit at the vent. The vent condensate
is typically drained at a drain tee located in the rst
section of vent pipe, as this should be the lowest
section of the vent pipe.
Consult local codes for direction on disposal of
condensate. In some cases (given code requirements
or drain material), condensate will need to be
neutralized. A condensate neutralizer is not included
with the unit, but is available from Mfgr as an
accessory. If a neutralizer is required, it is helpful to
install the boiler on a raised 4” concrete platform. This
will generally allow sufficient elevation for the
condensate neutralizer to be installed below the
condensate trap. See Figure 16.
If the unit is installed outdoors in a location that
may experience freezing temperatures, precautions
must be taken to prevent condensate from freezing.
Damage due to freezing condensate is not covered by
this units warranty.

CAUTION
Condensate is mildly acidic (pH=5) and may harm
some oor drains and/or pipes, particularly those
that are metal. Ensure that the drain, drainpipe,
and anything that will come in contact with the
condensate can withstand the acidity, or neutralize
the condensate before disposal. Damage caused
by failure to install a neutralizer kit or to
adequately treat condensate will not be the
manufacturer’s responsibility.
