What it is
The Navien packing is a sealing component that fits at the nozzle on NCB-CE series boilers. It forms the seal between the nozzle and its mating surface, preventing water or condensate from escaping at that joint. It is supplied under Navien part number 20030893A.
Signs this part needs replacing
- Water or condensate weeping from the nozzle joint
- Visible drips or damp staining around the nozzle area
- The packing is hardened, flattened or cracked
- Scale or debris build-up on the sealing face
