Viessmann 7826516 Ignition Electr.
When you're servicing a Viessmann Vitodens 200 or 222-F unit, reliable ignition is the baseline for high-efficiency combustion. The Viessmann 7826516 Ignition Electrode is the OEM replacement designed specifically for the WB2B, B2HA, B2HB, B2TA, and B2TB burner assemblies. This kit includes the necessary high-temperature ignition electrode gasket, ensuring a gas-tight seal at the mounting flange after you’ve pulled the burner for a maintenance check. Over time, electrodes degrade due to thermal stress and carbon buildup, leading to weak spark generation or nuisance lockout codes like Fault F4 (No flame signal).
Replacing this gas boiler ignitor is a routine part of a full combustion service to prevent intermittent ignition failures. This component is engineered for precise spark indexing within the burner tube, providing the immediate arc required to light the gas-air mixture. As a genuine Viessmann part, this electrode maintains the exact tolerances required for the Vitodens series, preventing the electrode-to-ground shorting issues often seen with generic alternatives. Always verify your 16-digit boiler serial number before installation to confirm the replacement 7826516 electrode matches your specific burner generation.
Key Benefits- Compatible with Viessmann Vitodens 200-W (B2HA, B2HB, WB2B) and 222-F (B2TA, B2TB) residential condensing boilers.
- Includes the sealing gasket to prevent flue gas leakage and maintain proper combustion chamber pressure.
- Restores consistent spark ignition performance, reducing the risk of delayed ignition or burner lockouts.
- Durable ceramic insulator and heavy-duty metal tips designed to withstand the high-cycle thermal demands of modulating gas burners.
Can I use this electrode if my boiler shows a Fault F4 error?
Yes, the Viessmann 7826516 is a primary troubleshooting component for F4 faults. If the ionization rod and gas valve are functioning, a worn or cracked ignition electrode is often the cause of failed ignition sequences.
Does this part include the mounting screws?
This item typically includes the ignition electrode with gasket. It is common practice to reuse the existing 4mm Allen mounting screws unless they show signs of significant corrosion or stripping.
How often should I replace the electrode and gasket?
In a professional setting, we recommend inspecting the electrode during every annual service. The burner gasket and electrode gasket should be replaced if they show any signs of compression set or brittleness to ensure the assembly remains airtight.
