What it is
The 5121477 bottom panel is a casing component manufactured by Main for use on selected Main and Potterton gas boilers. It forms the lower section of the appliance casing, closing off the underside of the boiler and protecting the internal components beneath the combustion and hydraulic assemblies. It is supplied as the panel only.
Signs this part needs replacing
- Visible corrosion or rust-through on the lower panel face
- Dents, buckling or distortion that prevents the panel sitting flush
- Panel edges bent so the fixings no longer align or hold
- Paint loss or surface damage exposing bare metal
- Panel fouling adjacent casing sections or the boiler's lower connections
Before you order
- Confirm the appliance model against the fit list above
- Check the serial number prefix and ending where the fit line specifies one
- Verify the panel position required — this part is the bottom panel only
- Inspect the existing fixings and surrounding casing for damage before fitting
