Navien’s new backlit control panel is simple and intuitive to use with its color‑coded plain text display, and an innovative click wheel that improves usability for all information input.
With Navien’s new PCB design you now have the ability to connect a boiler pump, 3 zone pumps or 3 zone valves, all integrated in the unit.
Navien’s NFB manifold kits are ideal for hydronic space heating applications. With these manifolds, we have done the piping work for you. Both primary and secondary loop manifold kits are designed to work on all NFB models for fast and clean installations. All you need to add is your own appropriately sized pump.

GFFM-MSOZUS-002
Secondary Manifold Kit
GFFM-SKTZUS-001
With our cascading technology, when a unit gets up to 80% capacity determined by the supply and return temperatures, the next unit will start to help meet the hydronic space heating requirements. This boiler sequence will continue until all units are generating the needed hydronic space heat up to the maximum cascaded capacity.
The Navien cascading system also balances out the workload of each unit for longer life. The NFB is dual certified for single and 2-pipe venting applications.
NaviLink makes it easy to communicate with your Navien systems anywhere internet service is accessible. The NaviLink module attaches easily to any new or existing* Navien tankless water heater, combi‐boiler and boiler.
* Existing installations may require the purchase of a new main PCB and front control panel.
