3. Each condensate drain must contain a siphon/
pigtail to prevent flue gas flow through the
condensate piping.
4. A common condensate pump/sump may
be used. Run separate piping from each
condensate drain to the sump. A common drain
may be used to discharge condensate from
the sump. Consult pump/sump manufacturer
for compatibility of pump/sump materials of
construction. If a common sump is used,
individual drain lines should be connected such
that one drain cannot back feed into another
drain.
5. Consult local authorities regarding disposal of
flue gas condensate into public waste water
system. Some jurisdictions require that the
condensate be buffered before discharge. This
buffering is commonly achieved by draining the
condensate through a limestone bed. Consult
a chemical treatment company for buffering
systems.
CAUTION
Do not use material that is not approved for use
with flue gas condensate.
