Information About 35-725911-117
The 35-725911-117 is part of Fenwal’s Series 35-72 family of 120 VAC DSI controls for natural, LP, and manufactured gas appliances up to 400 K BTU. It supports common mounting formats (open board with stand-offs or potted) and offers thermostat/power-off lockout reset. The controller’s microprocessor manages pre-/inter-purge timing, multiple ignition attempts, and flame sensing, while on-board diagnostics and flame-current test pins simplify commissioning and service. Typical applications include commercial cooking equipment, ceramic/black-body infrared heaters, and construction heaters.
Key Features:
- 120 VAC DSI Control: Direct spark ignition for gas valves and burners on line-voltage appliances.
- Configured Sequence (This Model): 3-try ignition with 15 s trial-for-ignition for dependable light-off.
- Flexible Mounting: Open board with stand-offs or potted versions for harsh environments.
- Quick Wiring: Multi-pin connector speeds assembly and reduces wiring errors.
- Serviceability: Diagnostic LED with error codes and flame-current test pins for fast troubleshooting.
- Polarity Insensitive: Reduces risk of miswiring on installation.
- Certified Design: CSA/ANSI design certification for automatic ignition systems.
The 35-725911-117 delivers the reliability and precision required for commercial and industrial gas ignition control.
