Fenwal 35-605605-113 Control

The Fenwal 35-605605-113 is a microprocessor-based 24V direct spark ignition (DSI) control engineered for precision timing and robust flame supervision in gas-fired appliances. This 35-60 series ignition module is designed for contractors requiring a reliable solution for residential and commercial furnaces, boilers, and water heaters. It features a 15-second pre-purge (15SecPP) to clear the combustion chamber and a 7-second trial for ignition (7SecTFI) to ensure safe flame establishment. Utilizing DETECT-A-FLAME® technology, the unit provides continuous flame rectification sensing with a minimum sensitivity of 0.7 µA. In the event of a flame failure, includes a 3-trial ignition sequence with 15-second inter-purge cycles before entering a secure lockout state. The on-board diagnostic LED simplifies troubleshooting by flashing specific fault codes, allowing for rapid field diagnostics without complex metering. Built with a Noryl enclosure, this control operates reliably in ambient temperatures ranging from -40°F to 176°F and is compatible with natural, LP, and manufactured gases.

• Precise Microprocessor Control: Delivers repeatable 15-second pre-purge and 7-second ignition timings for consistent system performance.
• Enhanced Safety Diagnostics: Integrated LED fault codes allow technicians to quickly identify ignition lockout or internal hardware errors.
• Multi-Try Reliability: Features 3 trials for ignition to improve startup success in challenging environments before requiring a manual reset.
• Flexible Sensing Options: Supports both local and remote flame sensing configurations to accommodate diverse burner geometries.
• Compact Noryl Enclosure: Designed for easy mounting in tight vestibular covers while providing resistance to moisture and vibration.

How do I reset the Fenwal 35-605605-113 after an ignition lockout?
Lockout can be cleared by cycling the 24 VAC power. Reset the thermostat or remove power from the control for at least 5 seconds to initiate a new ignition sequence.

What does a steady-on diagnostic LED indicate?
A steady-on LED typically points to an internal microprocessor or hardware failure. If power cycling does not clear the light, the control module likely requires replacement.

Can this module be used with both Natural Gas and Propane?
Yes, this direct spark ignition control is rated for use with natural, LP, and manufactured gases, provided the burner and orifice are correctly configured for the fuel type.
