Description
The Fenwal 35‑725205‑017 Direct Spark Ignition Control Module is a reliable 120 VAC microprocessor‑based ignition control designed to manage burner ignition and flame sensing in gas‑fired heating equipment. This control module delivers precise timing, repeatable ignition sequencing, and robust safety monitoring for a wide range of HVAC and industrial applications. Specifically engineered for controlling gas valves and ignitors in LP or natural gas systems, the 35‑725205‑017 module ensures consistent spark generation and flame detection, helping heating systems start quickly and operate efficiently. The microprocessor‑based design provides adaptable ignition timing sequences—including inter‑purge and multiple ignition trials—while built‑in diagnostics support easier service and troubleshooting.
Key Features
- 120 VAC Direct Spark Ignition Control: Microprocessor‑based design for accurate and repeatable ignition timing.
- Multiple Ignition Trials: Supports single or three ignition attempts before lockout to improve reliability.
- Flame Sensing: Detects flame presence and shuts off spark upon successful ignition to enhance safety.
- Inter‑Purge Timing: Integrated inter‑purge interval helps clear combustion gases between ignition attempts.
- Durable Construction: Multi‑pin connectors and conformal coating help ensure stable performance in demanding environments.
