Fenwal 35-652500-001 Ignition Module
The Fenwal 35-652500-001 Ignition Module is a high-performance 24VAC Hot Surface Ignition (HSI) Control engineered for gas-fired appliances including commercial burners, boilers, and furnaces. Designed with a robust microprocessor-based architecture, this module provides precise, repeatable timing for critical ignition sequences. It features a 4-second Trial for Ignition (TFI) and a 20-second HSI element heat-up period, ensuring reliable light-offs even in demanding environments. This specific configuration operates with 0-second pre-purge and 0-second inter-purge timings, making it an ideal choice for systems requiring immediate ignition response upon a call for heat.
For field diagnostics, the unit incorporates an on-board LED indicator that simplifies troubleshooting by communicating system status and fault codes. It utilizes DETECT-A-FLAME® technology for full-time flame sensing, effectively monitoring the burner from start-up through the entire heating cycle. The 35-652500-001 is built to withstand operating temperatures from -40°F to 176°F and supports remote flame sensing configurations. Its compact footprint and 120/240V field-selectable line voltage capability for the ignitor relay provide the versatility needed for various HVACR direct replacement applications.
Key Benefits:
- Broad Compatibility: Supports Natural, LP, and Manufactured gas types for versatile application across different heating platforms.
- Advanced Diagnostics: The integrated diagnostic LED provides rapid identification of airflow faults, ignition lockouts, and false flame signals.
- Precision Timing: Microprocessor control ensures consistent 4-second ignition timing and eliminates mechanical drift found in older controllers.
- Reliable Flame Sensing: Utilizes a 1.0 microamp minimum flame rectification signal to prevent nuisance shutdowns and ensure safe operation.
Common Questions:
What does a steady LED light mean on the 35-652500-001?
A steady LED typically indicates an internal control failure. Technicians should verify 24VAC input and ground integrity before determining if the module requires replacement.
Can I use this module with a 120V hot surface ignitor?
Yes, the Fenwal 35-652500-001 features field-selectable line voltage, allowing it to control either 120VAC or 240VAC ignitors via the L1 and L2 terminals while the board itself operates on 24VAC power.
How do I measure the flame current on this unit?
You can measure the flame current by connecting a DC micro-ammeter to the FC+ and FC- test pins. A strong, stable reading should be at least 1.0 microamp DC.
