Description
The Fenwal 35 705506 023 120V DSI Ignition Control Module and its equivalent listings are professional grade ignition control boards engineered for gas fired appliances and heating systems requiring reliable combustion initiation and flame safeguarding. This 120 VAC microprocessor based Direct Spark Ignition (DSI) control delivers consistent performance and advanced diagnostics for furnaces, boilers, water heaters, commercial cooking equipment, and other gas burner applications.
Key Features
- Direct Spark Ignition (DSI) Logic: Uses electronic spark ignition to reliably light burners without a standing pilot system — improving ignition efficiency and safety.
- 120 VAC Input Power: Designed for systems with standard line voltage, providing robust ignition control for larger appliances.
- Microprocessor Based Timing: Ensures precise, repeatable sequence control for ignition, inter purge, and flame sensing.
- Trial for Ignition (TFI): Includes approximately 7 second trial for ignition timing before lockout, enhancing safety.
- Inter Purge Control: Built in 15 second inter purge delay helps ensure proper combustion air conditions.
- Remote or Local Flame Sensing: Supports flexible installation and reliable flame verification.
- On Board Diagnostics: LED output simplifies troubleshooting and reduces service time.
- Multi Try Ignition Options: Capable of multiple ignition attempts before lockout for added reliability.
