Ideal Logic Max L2 flame-loss lockout

What Does Error L2 Mean?

On the documented Ideal Logic Max Combi, L2 is a flame-loss lockout. It records failure to establish or retain valid flame through the supervised sequence; it does not prove a dirty electrode. Gas pressure, valve command, spark, electrode and lead, condensate, flue, flame signal, and control require qualified tests. Applies to: Logic Max Combi boilers in manual 237660 A01 This L2 interpretation is limited to Logic Max Combi models covered by Ideal manual 237660 A01. Vogue, older Logic, Logic Air, and commercial Ideal appliances use their own fault tables. Owner-safe checks: Save L2, the model, other gas-appliance status, and audible startup sequence from outside the sealed case without forcing repeated ignition. Qualified technician: Gas pressure, valve, spark, electrode, flame-current, combustion, flue, condensate, wiring, and sealed-case work require a Gas Safe registered engineer.
