2. Place the free end of the drain line into an
appropriate drain.
3. If you are using a condensate pump, ensure that
the pump allows for up to 3 GPH of drainage for
each boiler in the system.
4. If you are not using a condensate pump, ensure
that the drain line is pitched downward at a
minimum slope of

To prevent property damage, do not allow
condensate line to freeze or become obstructed
or condensate can flow from the drain.
5. Fill the condensate trap by pouring water into
the boiler's exhaust vent until water flows
through the condensate drain.

3.2.1 Condensate Neutralizer Kit
WARNING
To prevent serious injury or death:
DO NOT allow exhaust flue gases to vent
●
through the neutralizer. Inhalation of
flue gases can result in carbon monoxide
poisoning.
ALWAYS install the neutralizer so its inlet and
●
discharge are closer to the floor than the
condensate drain.
ALWAYS install an overflow bypass connection
●
between the appliance and the neutralizer to
prevent the backflow of condensate into the
appliance.
DO NOT connect more than one appliance to
●
the neutralizer.
If option 'b' (p. 23) is selected as the disposal
option, the Navien condensate neutralizer kit is
recommended. The condensate from the appliance
flows through the neutralizing media and increases
the pH of the condensate. An increased pH prevents
corrosion of the installation's drainage system and
the public sewer system.
Installation
The inlet has a center connection port and the
●
outlet has an offset connection.
Install the neutralizer on the wall or the floor and
●
secure it using the brackets supplied with the kit.
If the neutralizer is installed horizontally, rotate
●
the neutralizer to position the outlet at the
highest point (Figure 1).
If the neutralizer is mounted vertically, ensure that
●
the outlet is higher than the inlet (Figure 2).
Ensure that the condensate runs freely to the
●
drain.
Ensure all connections are made to prevent
●
the backflow of condensate. Use corrosion
resistant piping and secure all piping to prevent
movement.
Do not install condensate piping in
Note
areas where the temperature drops
below freezing point. Protect piping in
high pedestrian areas from damage and
vibration.
