What it is

The Valor mains block insulation is a piece of Nomex 410 insulating material with a 0.25 mm thickness, listed by the manufacturer under part number 85057. It is fitted at the mains block on Valor boiler appliances, where its purpose is to insulate the block. It is a service item rather than a functional boiler component.

Before you order

  • Confirm the appliance is a Valor boiler and that mains block insulation is the item required.
  • Check the thickness of the insulation being removed against the 0.25 mm stated here.
  • Cross-check part number 85057 against the manufacturer's documentation for the appliance.
  • Isolate the electrical supply to the boiler before removing or fitting insulation at the mains block.
