What it is
The Navien Endvent Packing is a sealing component used at the end vent assembly on Navien LCB 700 boilers. It is supplied under part number 20043645A and forms part of the flue terminal sealing arrangement on the appliance. The packing maintains a sealed joint at the end vent, preventing leakage of flue gases or condensate at that connection point.
Signs this part needs replacing
- Visible deterioration, cracking or hardening of the packing material at the end vent
- Staining or discolouration around the end vent joint indicating a seal has failed
- Condensate or flue gas leakage at the terminal connection
- Vibration, movement or looseness at the end vent assembly where the packing no longer seats correctly
Before you order
- Confirm the appliance is a Navien LCB 700 and identify whether it is combi, regular or system
- Check the model output rating (21KW, 28KW or 36KW) and whether the boiler is internal or external
- Verify the serial number against the fitment list before ordering
- Inspect the end vent assembly to confirm the packing, rather than another component, is the failed item
