Fenwal 35-655005-013 Control

The Fenwal 35-655005-013 is a specialized 24VAC direct spark ignition (DSI) control designed for precise dry steam boiler applications. This microprocessor-based module manages the ignition sequence, flame monitoring, and safety shut-off functions with a 15-second trial for ignition (TFI). Engineered for single rod flame sensing, it utilizes a local sense configuration to maintain reliable operation in high-moisture environments. The control board features a diagnostic LED for rapid troubleshooting of lockout conditions, reducing downtime during field service. Its robust construction ensures stable performance against voltage fluctuations and mechanical vibration. When replacing older ignition modules, this unit provides a direct fit for compatible Fenwal series, ensuring the intermittent pilot or direct spark system operates within OEM specifications for steam generation equipment.

• Voltage Input: 24VAC (18-30 VAC) 50/60Hz for standard HVAC control circuits.
• Ignition Type: Direct Spark Ignition with a 15-second TFI for reliable burner light-off.
• Flame Sensing: Integrated local sense circuitry for accurate flame rectification feedback.
• Safety Logic: Automatic 100% shut-off upon flame failure to prevent gas buildup.
• Diagnostic Support: On-board LED indicator facilitates immediate fault code identification.
• Application Specific: Optimized for dry steam systems requiring specific timing profiles.

Is the Fenwal 35-655005-013 compatible with remote sense applications?
No, this specific model is configured for local (single rod) sensing. Ensure your electrode assembly matches this configuration before installation.

What does a steady flash on the diagnostic LED indicate?
A steady flash typically indicates a lockout condition due to a failure to ignite or a loss of flame signal. Always verify gas pressure and electrode gap before replacing the module.

Can this module replace other 35-65 series controls?
While the footprint is similar, timing and trial periods vary. You must match the specific dash number (-013) to ensure the purge and ignition timings meet the appliance's safety requirements.
