56 Rinnai M - Series Condensing Boiler Combi Manual
•
Do not plumb the condensate drain
with the pressure relief valve; both
must be plumbed independently to
drain.
•
All condensate must drain and be
disposed of according to local codes.
•
Use only corrosion resistant materials
for the condensate drain lines such as
PVC pipe or plastic hose.
•
The condensate drain pipe (along its
entire length) must be at least 1/2 in.
•
Condensation drain lines installed in
areas that are subject to freezing
temperatures should be wrapped with
an approved supplemental heat
source. Install per manufacturer
’ s
instructions.
•
Slope the condensate drain lines
toward the inside floor drain or
condensate pump.
•
The end of the condensate drain pipe
should be open to the atmosphere.
The end should not be under water or
other substances.
•
If the condensate drain pipe is closed or
stuck, the drain water will come out from the
side hole on the condensate drain pipe
connection.
•
If a floor drain is not available or the drain is
above the level of the condensate drain, a
condensate pump should be installed.
•
A condensate neutralizer kit is available from
Rinnai. The kit allows condensate to flow
through neutralizing media that raises the
pH of the condensate to a level that will help
prevent corrosion of the drain and public
sewer system. Refer to section
“ 3.6
Accessories ” for more information.
•
The condensate drain pipe should be as short
as possible and have a downward pitch.
•
Before operation of the boiler, the
condensate collector must be filled with
water.
