1.3 Compatible Products & Pump
Requirements
The NaviCirc is most compatible with Navien NPE-A Series water
heaters.
NPE-A models may utilize the built-in pump along with the
appropriate piping to create a hot water recirculation loop. If
the NaviCirc is used on a non-Navien appliance, consult the
manufacturer for compatibility and size the pump with the
following head requirements:
Pump MAX head approx. 15 ft (4.6 m) – 23 ft (7 m)
Note
Navien does not guarantee the performance of the
NaviCirc when used on a non-Navien appliance.
CAUTION
If the selected external pump does not meet the recommended
specications provided in this manual, the NaviCirc may not
operate properly.
