F.380 — Burner in a fault state (Flame loss immediately after flame formation)

What does F.380 mean?

The burner loses its flame immediately after it has formed, during the safety time. This can be due to gas supply issues, flue gas problems, or issues with the ionization electrode.

• Insufficient gas supply (low gas pressure)
• Flue gas recirculation in balanced flue system
• Clearance issues or contamination of ionization electrode and flame body assembly
