What it is
The Navien 30031683A is the top case panel for the LCB 700 range of external boilers. It forms the upper section of the appliance casing, enclosing and protecting the components beneath. It is supplied as the top case only.
Signs this part needs replacing

- Dents or deformation that stop the case seating correctly
- Cracks or splits allowing water ingress to the components below
- Paint flaking or impact damage to the panel
- Broken edges or fixing points so the panel no longer secures
Before you order

- Check whether the appliance is a Regular External or System External variant
- Inspect the fixings and seals around the top case for damage
- Check the existing part number where it is visible on the old panel
