Fenwal 35-705506-023 Control
The Fenwal 35-705506-023 is a high-performance 120V Direct Spark Ignition (DSI) control engineered for precision sequence management in gas-fired appliances. Built with advanced microprocessor-based circuitry, this module provides reliable 120VAC ignition control for furnaces, commercial cooking equipment, and infrared heaters. This specific model is configured for a 0-second pre-purge, a 15-second inter-purge delay, and a 7-second trial for ignition (TFI) period. The integration of flame current test pins allows for immediate diagnostic signal measurement using a standard micro-ammeter, significantly reducing field troubleshooting time. With a robust temperature rating from -40°F to 175°F, it ensures consistent burner ignition sequencing and safety monitoring in demanding environments. This Fenwal ignition module is designed for polarity-insensitive flame sensing, minimizing potential wiring errors and streamlining installation for field contractors.
Key Benefits- Precision Timing: Microprocessor logic ensures repeatable 0s pre-purge and 7s TFI sequences for consistent burner starts.
- Diagnostic Support: On-board LED provides clear fault codes for rapid system status identification.
- Flexible Sensing: Supports local or remote flame sensing configurations to match specific appliance designs.
- Flame Safeguard: Detect-A-Flame technology provides reliable flame monitoring and automatic safety lockout.
- Contractor Friendly: Polarity insensitive sensing and standard 1/4" quick-connect terminals simplify the upgrade or replacement process.
What is the purpose of the 15-second inter-purge?
The 15-second inter-purge ensures that any unburned gas is cleared from the combustion chamber between ignition attempts, maintaining a safe environment for the subsequent spark.
How do I measure the flame signal on this control?
Utilize the dedicated on-board flame current test pins (FC+ and FC-) with a DC micro-ammeter. A stable signal of 1.0 μA or higher is required for reliable operation.
Can this module be used with both Natural Gas and LP?
Yes, the Fenwal 35-70 series is compatible with Natural, Manufactured, and LP gas types, provided the appliance regulator is correctly set.
