We just checked with our manufacturers representative and they confirmed you can actually use the cascade cable to cascade up to 15 NPE's with NFC or NCB. You can use these models together since the combi boiler already handles domestic, we're just giving them for capacity. And you can common vent them too! Thanks for looking out for us! 🙏
Love that Intro 😂😂😂

Navien only recommends using the cascade cable with similar heaters
