What it is
The Viessmann Venturi Extension W Gasket is a flue component used on Vitodens gas boilers. It forms part of the combustion air and flue gas path, where the venturi influences airflow through the appliance. The assembly is supplied with its gasket, which seals the joint at the point of fitment.
Signs this part needs replacing
- Combustion readings outside the appliance's expected tolerance, pointing to incorrect airflow through the venturi
- Visible cracking, distortion or corrosion on the venturi extension
- A perished, hardened or torn gasket at the venturi joint
- Signs of leakage or staining around the flue connection
- Whistling or unusual noise from the flue or air intake under operation
Before you order
- Confirm the appliance model and serial number against the fits list above, as fitment is serial number specific
- Check the existing venturi extension and gasket for damage before ordering
- Verify the manufacturer part number 7827958 matches the component being replaced
- Ensure the boiler is isolated and any combustion work is carried out by a competent Gas Safe registered engineer
