Description
The Supco FLS013 Flame Sensor is a safety control component used to verify the presence of a burner flame in gas-fired heating equipment. It operates by detecting ionization current generated when a flame is present allowing the control system to confirm safe ignition and continued combustion. It is applied in HVAC systems within furnace assemblies to monitor burner operation and signal the control board when flame conditions change. It is positioned directly in the flame path to provide detection during heating cycles, supporting controlled ignition sequences and consistent system operation.
