What it is
The Navien heat exchanger middle elbow pipe, part number 30013744A, is a formed pipe section that sits within the heat exchanger assembly on Navien NCB-CE ERP boilers. It carries water through the middle elbow position of the heat exchanger circuit. It is a service component intended for replacement when the existing elbow is leaking, corroded or restricted.
Signs this part needs replacing
- Water weeping, dripping or staining around the middle elbow joint
- Visible corrosion, pitting or heavy scale build-up on the pipe
- Falling system pressure that needs frequent topping up with no other obvious cause
- Kettling or gurgling noises from the heat exchanger area
- Localised overheating or heat exchanger fault codes linked to restricted flow
Before you order
- Confirm your boiler model against the fit list above
- Check the serial number of your appliance, as fitment is listed by model and serial range
- Inspect the middle elbow position on the heat exchanger to confirm this is the section required
- Check whether associated seals, washers or adjacent pipe sections also need replacing at the same time
