Fenwal 35-630501-003 Module
The Fenwal 35-630501-003 is a microprocessor-based intermittent pilot ignition control designed for precise spark-to-pilot sequences in gas-fired atmospheric burners. Engineered for 24VAC systems, this HVAC ignition module provides high-reliability timing via advanced digital circuitry, ensuring repeatable intermittent pilot sequences across residential and commercial heating applications. This specific Fenwal ignition module features a 30-second Trial for Ignition (TFI) and a 0-second pre-purge, making it an ideal OEM replacement part for equipment requiring immediate spark activation.
For technicians troubleshooting in the field, the unit includes onboard diagnostics with a built-in LED to rapidly identify system faults. With remote flame sensing capabilities, this 24-volt ignition control supports flexible electrode placement, utilizing DETECT-A-FLAME technology for superior flame rectification monitoring. The Noryl gray enclosure provides a durable, flame-retardant housing suitable for mounting on standard 4-inch junction boxes. Whether you are servicing a boiler, water heater, or commercial cooking range, this Fenwal 35-63 series module delivers the rugged performance required for high-duty cycle environments.
Key Benefits- Precise timing: Microprocessor logic manages 30-second TFI and ignition sequences without the drift associated with analog controls.
- Diagnostic LED: Simplifies field service by indicating lockout status and hardware errors through specific flash codes.
- Flexible Sensing: Supports both local and remote flame sensing to accommodate diverse burner configurations and flame rods.
- Environmental Protection: The IP classification and Noryl housing protect internal circuitry from typical mechanical room stressors.
- Safe Start: Integrated self-check routines verify internal component integrity before every call for heat.
- How do I resolve a 3-flash LED code on this Fenwal module? A 3-flash signal typically indicates an ignition lockout. Check the pilot gas supply, ensure the peak-to-peak spark gap is approximately 1/8 inch, and verify the flame sensor is clean and properly grounded.
- Can I use this module for both Natural Gas and Propane (LP)? Yes, the Fenwal 35-630501-003 is compatible with natural, manufactured, and liquefied petroleum gases when used with the appropriate gas valve and orifice settings.
- What is the minimum flame current required for operation? For reliable flame rectification on this 24VAC module, ensure a minimum flame current of 0.7 microamps DC is detected at the FC test points.
