The BG1600M51E1AA is a microprocessor based ignition control. The microprocessor provides reliable software control of all timings and operates a diagnostic LED. It provides ignition sequence, flame monitoring, and safety shutoff for intermittent pilot boilers, furnaces and other heating appliances.
BASO has designed-in features to retrofit other universal direct spark ignition controls with spark ignition and flame rectification such as: Johnson Controls, Honeywell, White Rodgers, Fenwal, and Robertshaw.
It replaces controls with the following specifications:

• Flame detection using flame rectification technology
• Single rod (local sense) or dual rod (remote sense) flame sensing
• 100% shutoff/lockout with 5 minute continuous retry
• Trial times of 25 seconds or longer
• Prepurge period 1 second or less
• Main burner 400,000 BTU/hr maximum
• Pilot burners with flow rates of 1,500 Btu/hr or less
• With or without automatic vent damper
• Must be used with redundant gas valves and not subjected to temperatures below -40°F or above 170°F
  Direct replacement to Johnson Controls G779LHA.
