Description
The Fenwal 35‑615908‑223 is a high‑quality 24 VAC Direct Spark Ignition (DSI) control module with blower relay engineered to deliver reliable ignition control and flame monitoring in gas‑fired HVAC systems and industrial heating equipment. It is microprocessor‑based and designed to manage precise ignition sequencing, safe burner start‑up, and continuous flame sensing for optimal performance and system safety.
Key Features
- 24 VAC microprocessor‑based DSI control with integrated blower relay for coordinated combustion airflow.
- 30‑second pre‑purge and inter‑purge timing to safely prepare the combustion chamber before and between ignition attempts.
- Reliable flame sensing and diagnostics with LED status indicators and flame trial support.
- Remote or local flame sensing options and test points for flexible installation and monitoring.
- Designed for natural gas, propane (LP), and manufactured gas applications in HVAC and industrial systems.
