What it is
The Potterton 5000857 is a fan inlet gasket used on Suprima gas boilers. It seals the joint between the fan inlet and the surrounding flue or air path components, preventing leakage of combustion air or flue gases at that connection. The gasket is a consumable sealing component and is normally renewed whenever the fan or the inlet joint is disturbed.
Signs this part needs replacing
- Visible cracking, hardening or flattening of the gasket material
- Traces of soot staining or condensate seepage around the fan inlet joint
- Combustion readings that drift or fail to settle after servicing the fan
- The gasket is disturbed, damaged or torn during fan removal or refitting
- Audible whistling or leakage at the fan inlet on a running boiler
Before you order
- Confirm the boiler model is a Suprima 30 L, 40 L or 50 L
- Check the existing gasket or the appliance data badge against part number 5000857
- Verify the gasket seating faces are clean and undamaged before fitting
- Confirm the fan and inlet assembly are otherwise serviceable, as the gasket is a sealing item only
