Fenwal 35-615955-997 Board
The Fenwal 35-615955-997 is a 24 VAC microprocessor-based Direct Spark Ignition (DSI) Control engineered for high-reliability performance in gas-fired heating equipment, including commercial boilers, furnaces, and water heaters. As an intermittent ignition control, this module replaces traditional pilot systems by generating a high-voltage spark to initiate combustion only when the thermostat calls for heat. This specific Fenwal 35-61 series board features a 45-second pre-purge and a 45-second inter-purge cycle to clear the combustion chamber of residual gases, ensuring a safe 15-second trial for ignition. Built-in on-board diagnostics with a dedicated LED simplified field service by providing clear flash codes for airflow faults, flame signal errors, and ignition lockout. Designed with a compact footprint, this OEM ignition board includes an integrated inducer blower relay (rated for 120/240 VAC) for streamlined system wiring and robust pressure switch monitoring to verify proper venting before the gas valve is energized.
Key Benefits for Contractors:
- Advanced Microprocessor Logic: Continually analyzes flame current and system safety parameters to prevent nuisance lockouts.
- Integrated Blower Control: Built-in relay manages the combustion inducer, reducing the need for external components.
- Maintenance Efficiency: Features flame sense test pins for easy troubleshooting of the microamp signal without breaking the circuit.
- Universal Application: Compatible with various gas-fired appliances in industrial and commercial cooking environments.
- Safety Compliance: Includes automatic one-hour reset and non-volatile lockout options to protect the equipment and end-user.
Common Questions & Troubleshooting:
- Why is the LED flashing 3 times? A three-flash code typically indicates an ignition lockout due to the system failing to prove flame after multiple tries; check gas supply and the spark electrode gap.
- What is the minimum flame current for this board? This module requires a minimum flame rectification signal of 0.7 microamps to maintain the gas valve circuit.
- Can this board be used for remote sensing? Yes, the 35-615955-997 supports both local and remote flame sensing configurations to match your specific burner assembly.
