About the Boiler 27
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 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 laundry tub,
as the alkali in laundry detergent will neutralize the acid in the
condensate. However, other suitable waste drain locations may be
used according to the local codes.
CAUTION
Ɣ
Do not cap or plug the integrated condensate line. If
prevented from draining, condensate can damage the boiler.
Ɣ
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.
2. Insert the condensate trap to the drain adapter at the bottom
of the boiler.
