30 Installing the Water Heater
3.5 Connecting the Condensate Drain
The Navien Condensing Water Heater creates condensation when
it operates. This condensation has an acidic pH of 3-5. Follow
all local codes and regulations when disposing of condensate
from the water heater. Check local codes for suitable waste drain
locations if applicable.
CAUTION
Ɣ
Fill the condensate trap with water after installing the
condensate drain pipe.
Ɣ
Do not cap or plug the integrated condensate line. If
prevented from draining, condensate can damage the water
heater.
Ɣ
The condensate line must have a negative slope to drain
properly.
Ɣ
Do not use condensate for drinking or for consumption by
animals.
Before connecting the condensate drain, choose one of the
following disposal options:
To the
laundry tub
Direct to the
external drain
External drain
To the laundry tub via
a condensate pump
To the
drain via a
neutralizer
a. From the water heater directly into an external drain.
b. From the water heater, through a neutralizing agent, and then
into an external drain.
Note
If you choose this option, the neutralizing agent
must be replaced periodically. Depletion of the
neutralizing agent will vary, based on the usage
rate of the water heater. During the first year of
operation, the neutralizer should be checked every
few months for depletion and replaced as needed.
c. From the water heater into a laundry tub.
Note
The bottom of the water heater must be higher
than the top of the laundry tub to use this option.
The condensate line must have a negative slope to
drain properly.
d. From the water heater into a condensate pump, and then into a
laundry tub.
Note
A pump can be used when there is a long distance
between the water heater and the laundry tub or
when the bottom of the water heater is lower than
the top of the laundry tub.
To connect the condensate drain:
1. Connect a drain line to the

water heater.
Use only corrosion-resistant material for the drain line, such as
PVC or CPVC. Do not reduce the size of this fitting or the drain
line to less than
