Installing the System Piping
2. Insert the condensate trap to the drain adapter
at the bottom of the boiler.
3. Attach the clip to the condensate trap.
4. Ensure that the condensate trap is firmly fixed to
the bottom of the boiler.
3.2 Connecting the Condensate
Drain
The Navien NFB-H boiler creates condensation
when it operates. This condensation has an acidic
pH of 3-5. Follow all local codes and regulations
when disposing of condensate from the boiler. We
recommend draining the condensate into a suitable
external drain. However, other suitable waste drain
locations may be used according to the local codes.
CAUTION
●
Do not cap or plug the integrated condensate
line. If prevented from draining, condensate
can damage the boiler.
●
The condensate line must have a negative
slope to drain properly.
To attach the condensate trap to the boiler:
1. Check the components of the condensate trap.
