
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.
CORRECT
Pipe open to

NOT
CORRECT
Pipe submerged


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.
DO NOT

DO NOT connect the condensate drain
line with an air conditioning
evaporator coil drain.

Boilers have an integrated condensate
trap. DO NOT install an external
condensate trap.
