Identifying Ignition Lockouts: What We Check First
Ferroli boilers, particularly the Modena and Optimax ranges, have a distinct lockout behaviour when ignition fails. This usually manifests as several attempts to ignite before a full lockout. Our initial checks focus on the ignition electrode and lead for damage or poor connection, and the flame sensing electrode for corrosion or incorrect positioning. We'll also verify adequate gas pressure at the boiler, as low pressure can prevent proper ignition, and ensure the fan is operating correctly to clear combustion products, allowing a stable flame.
- Verify ignition electrode condition
- Inspect flame sensing electrode
- Test gas pressure at boiler
- Confirm fan operation
