What it is

This is the radial fan gasket for Viessmann Vitodens gas boilers, supplied under part number 7829796 and the product name GASKET (RADIAL FAN) WBXB. It sits at the radial fan mounting joint and seals that connection against flue gas and air leakage. The gasket is a service item used when the fan is removed or refitted during repair and servicing work.

Signs this part needs replacing

  • The gasket is brittle, hardened, crushed or visibly split when the fan joint is opened
  • Flue gas or condensate staining around the radial fan mounting face or housing joint
  • Whistling, popping or unstable combustion readings that point to air being drawn in at the fan joint
  • The fan has been removed for cleaning or replacement and the old gasket will not reseal

Before you order

  • Match the boiler model and serial number on the data badge against the fit list above
  • Confirm the existing gasket profile and position on the radial fan mounting face
  • Check the radial fan itself for wear, noise or contamination before refitting
  • Have the fan joint faces clean and undamaged before fitting the new gasket
