What it is
The Viessmann ionization cable inside L=390, part 7822949, is a flame sensing lead used on Vitodens gas boilers. It carries the ionization signal from the burner electrode back to the boiler control, which uses that signal to confirm a flame is present. The cable is supplied at the L=390 length designation listed for this part.
Signs this part needs replacing
- The boiler locks out shortly after the burner lights, with a flame detection fault recorded.
- The ignition sequence runs but the burner shuts down because no flame signal reaches the control.
- Intermittent lockouts that clear when the lead or its connector is disturbed.
- Visible damage to the cable insulation, the connector or the electrode end of the lead.
Before you order
- Confirm the boiler model and serial number against the fit list above.
- Check the routing and the L=390 length designation against the cable being removed.
- Match the part number 7822949 to the number on the existing lead.
- Inspect the ionization electrode and its connector at the same time, in case they also need attention.
