OEM Lennox Igniter Kit DKVLT-150/200 — Y5351

The genuine OEM Lennox Y5351 igniter kit is designed specifically for Lennox wall-mounted condensing gas boilers, including the DKVLT-150 and DKVLT-200 models. The igniter heats to a high temperature to reliably light the burner on each call for heat, making it one of the most critical components in your boiler's ignition sequence. The kit includes the igniter and mounting hardware needed for a clean, correct installation.

Common failure symptoms: A failing igniter is one of the most frequent causes of no-heat calls. Watch for a boiler that ignites intermittently or not at all, repeated ignition-failure lockouts on the control board, a visibly cracked or discolored igniter element, or longer-than-normal delays before the burner lights. Because igniters are brittle and degrade with thermal cycling, they are a common wear item.

Why OEM matters: The Y5351 is matched to the exact voltage, resistance, and physical geometry of the DKVLT burner assembly. Generic igniters can seat improperly, draw incorrect current, or fail prematurely. Choosing the factory Lennox part ensures dependable ignition, protects your boiler's control system, and keeps your unit within its original specifications.
