Viessmann 7836815 Ignition Electr.

The Viessmann 7836815 Ignition Electrode is a critical service component engineered for high-output Vitodens 200-W B2HA series condensing gas boilers, specifically the 112, 150, 399, and 530 models. As a veteran technician, you know that consistent arc generation is paramount for efficient combustion cycles; this genuine OEM part ensures precise spark delivery to initiate the heating process without delayed ignition. The kit includes the high-temperature gasket (w/ gskt) necessary to maintain a pressure-tight seal at the burner door, preventing dangerous flue gas leakage into the cabinet. When diagnosing "no flame" signals or ignition faults, checking the porcelain insulator for cracks and the electrode tip for carbon buildup is standard protocol. Replacing this boiler ignition part during annual maintenance prevents emergency lockouts and optimizes the ionization current for the control board's flame sensing circuit. Always verify the 16-digit boiler serial number to confirm exact fitment for residential wall-mounted gas-fired condensing boilers.

• Direct OEM Replacement: Ensures full compatibility with Vitodens 200-W B2HA residential and commercial boiler manifolds.
• Leak-Proof Integration: Includes the sealing gasket required to maintain the integrity of the combustion chamber seal.
• Reliable Arc Generation: Specifically designed for gas-fired condensing boilers to provide stable ignition under high-efficiency operational parameters.
• Combustion Precision: Maintains proper electrode-to-burner spacing, critical for preventing flame rectification errors.

Which boiler models are compatible with this electrode?
This part is specifically designed for the Viessmann Vitodens 200-W B2HA series, particularly 112/150 and 399/530 MBH models. Always check your boiler serial number before installation.

Does the kit include the mounting gasket?
Yes, the 7836815 is supplied with the ignition electrode gasket to ensure a gas-tight fit upon reassembly.

Why is my boiler failing to ignite even with a new electrode?
If the electrode is new, inspect the ignition cable harness for continuity and ensure the control board is outputting the proper voltage for spark generation.
