What it is

The Navien 20058231A is a wall mounting bracket used to secure Navien NCB300 and NCB500 combi boilers to the wall. It forms the fixing interface between the appliance casing and the wall structure, holding the boiler at its correct position and load-bearing point. It is a Navien-manufactured part for the NCB300 and NCB500 combi families.

Signs this part needs replacing

  • Visible corrosion, rust staining or pitting on the bracket surface
  • Bracket distorted, bent or cracked, so the boiler no longer sits square
  • Boiler casing sitting proud of the wall or rocking on its mounting point
  • Fixing holes elongated or wall fixings no longer gripping through the bracket
  • Vibration or movement at the boiler when running

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the existing bracket part number before removing it, where it is still legible
  • Inspect the wall fixings and the wall itself for damage, as these are separate from the bracket
  • Confirm whether the bracket is supplied with any fixings before ordering, as pack contents are not stated here
