Tech Tip: Flame Rectification and Signal Measurements

Flame rectification is commonly measured in Microamps DC, which is used to detect the presence of a flame in the system. A strong flame signal typically ranges from 1.5 to 6 Microamps DC, depending on the AC voltage output from the control board.

If the flame signal drops below 0.7 Microamps DC, most control boards will trigger a fault for flame loss. Monitoring and maintaining proper flame signal strength ensures the reliable operation of your system.
