What it is

The Satronic MZ770S is a 40mm photocell used for flame detection on oil-fired burners. It monitors the flame during the burner run cycle and signals the control box when the flame is present or lost. It is listed for EOGB Satronic oil boiler applications.

Signs this part needs replacing

  • Burner locks out shortly after ignition
  • Repeated lockouts even when a flame is visibly present
  • Intermittent or erratic flame detection during the run cycle
  • Soot or contamination on the photocell window
  • Burner fails to complete its cycle and trips to lockout

Before you order

  • Confirm your burner or boiler model against the manufacturer's parts list
  • Check the existing photocell is marked MZ770S
  • Verify the 40mm body length matches the part being replaced
  • Inspect the photocell holder and window for contamination before fitting a replacement
