What it is
The Viessmann Gas Solenoid Valve 7828721 is an electrically operated valve used to control the flow of gas into the burner assembly on Viessmann gas boilers. It is listed by Viessmann under part number 7828721 and sits within the gas valve group of gas boiler spares. The valve opens and closes on command from the boiler's control sequence, regulating gas supply to suit demand.
Signs this part needs replacing
- The boiler fails to light or locks out because gas is not being admitted to the burner
- The burner lights intermittently or drops out during a demand for heat or hot water
- Gas is not shut off cleanly when the boiler ends a firing cycle
- Fault codes or lockout behaviour pointing to a gas valve or ignition sequence fault
- Audible clicking from the valve area without the burner firing
Before you order
- Confirm the boiler model and serial number against the fit list above, as the valve is matched to specific Vitodens 100-W WB1B and 100W Compact variants
- Check the existing valve for the Viessmann part number 7828721 before ordering
- Gas-carrying components must be fitted and commissioned by a Gas Safe registered engineer, with tightness testing and combustion analysis carried out afterwards
- Verify the boiler is not showing a fault relating to another component in the ignition or gas train before replacing the valve
