What it is

The Potterton NXR3 rear top casing panel is a red outer casing component for the NXR3 range of Potterton Commercial boilers. It forms the rear section of the top casing assembly, closing off the upper rear of the appliance. The panel is supplied for use across the 4 to 9 section NXR3 variants.

Signs this part needs replacing

  • Visible corrosion, rust staining or pitting along the rear top panel
  • Dents, buckling or impact damage to the casing face
  • Paint flaking or deterioration exposing bare metal
  • Panel no longer seating correctly, leaving the boiler casing open or insecure
  • Distortion that interferes with the fit of adjoining casing sections

Before you order

  • Confirm the boiler is an NXR3 and check the section count (4 to 9 section) against the listing
  • Compare the existing panel shape, mounting points and colour with the part described
  • Check whether any adjacent casing components are also damaged and need replacing at the same time
  • Isolate the appliance and allow it to cool before removing or refitting casing panels
