What it is

The condensate trap is a Navien component used on NCB-CE system and combination boilers. It collects the condensate formed in the heat exchanger and flue, discharges it to the drainage point, and seals the flue path so combustion gases cannot escape through the condensate route. It is supplied under Navien part number 30019021A.

Signs this part needs replacing

  • Water collecting or dripping from beneath the boiler casing
  • Gurgling or bubbling noises from the condensate route during operation
  • Boiler locking out with a condensate or flue-related fault
  • Visible cracks, scale or sludge blocking the trap body or its outlet
  • Persistent drain smell or flue odour around the boiler

Before you order

  • Confirm the boiler model and serial number against the fit list above
  • Inspect the existing trap for cracks, blockages or a part number match
  • Check that the trap connections and orientation suit the installation
