What it is
The Potterton 5142346 is a blanking plate for Potterton Commercial Sirius 2 and Sirius 3 boiler ranges. It seals an unused tapping or port on the appliance, closing the connection so the boiler casing and waterways remain sealed in service. It is a service component rather than a functional control or sensor.
Signs this part needs replacing
- A weep or drip tracked to a blanked-off tapping or port
- Visible corrosion or pitting on the plate face or its sealing face
- The plate is missing or has been left off after servicing
- The plate is loose or does not sit square against the mating face
- Staining or scale build-up around the blanked connection
Before you order
- Confirm the appliance model and range against the fit list above
- Check the part number 5142346 matches the number on the existing plate or in the boiler documentation
- Confirm whether the blanking plate is supplied with a sealing washer or gasket, as the plate alone may not be sufficient to reseal the port
- Inspect the mating face for damage before refitting a new plate
