Navien NPE-240S external circulating pump

[54fred]

What do I need and how do I install a circulating pump on the Navien NPE-240S?

Check valve, pump, and a tee. Set the dip switches. I think. But the install manual should tell you everything you need to know.

Here's a service manual. Page 140 shows a built in pump but saw some info only the npe 240 A had a pump.

Bad idea. Trade out and get NPE A2 series.

The manual explains it.

To install an external circulating pump on the Navien NPE-240S, you'll need a few things. First, make sure you have the pump itself, along with any necessary fittings and piping. You'll also need a power source nearby.
