Condensate Neutralizer Kit; Horizontal Installation; Vertical Installation - Navien NPE-180A2 Installation Manual

3.5.1 Condensate Neutralizer Kit

WARNING
To avoid damaging the appliance, the
●
neutralizer inlet and discharge must be lower
than the condensate drain.
Do NOT allow exhaust flue gases to vent
●
through the neutralizer. Leakage can cause
injury or death from carbon monoxide.
The connection between the appliance
●
and the neutralizer must be installed to
prevent the backflow of condensate into the
appliance.
Do not connect more than one appliance to
●
the neutralizer.
If option 'b' is selected for condensate disposal, 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.
Optional
overflow bypass

[Horizontal installation]

If the neutralizer is mounted vertically, ensure that
●
the outlet is higher than the inlet.
Optional
overflow bypass

[Vertical installation]
