What it is

The Viessmann wall bracket, part number 7834990, is the mounting bracket used to secure Vitodens 100-W boilers to the wall. It carries the weight of the appliance and holds the boiler in its correct position for flue and pipework connections. This bracket is listed for use across a range of Vitodens 100-W system and combi models.

Signs this part needs replacing

  • The bracket is bent, distorted or no longer holds the boiler square to the wall.
  • Visible corrosion, heavy rust or material loss around the bracket body or fixing points.
  • The boiler sits loose, rocks or has dropped out of its original alignment.
  • Cracks or fractures in the bracket, particularly at bends or fixing holes.

Before you order

  • Confirm the boiler model and serial number against the fit list before ordering.
  • Check the existing bracket for damage and confirm the part number matches 7834990.
  • Inspect the wall fixings and boiler mounting points at the same time, as these may also need attention.
  • Confirm whether the boiler must be isolated and drained before the bracket is removed or refitted.
