Description
The Fenwal 35‑725205‑015 is a professional‑grade 120 VAC direct spark ignition (DSI) control module designed to reliably manage ignition sequencing and flame sensing in gas‑fired heating equipment and industrial appliances. Its microprocessor‑based design ensures precise and repeatable timing for ignition trials and flame monitoring, making it suitable for furnaces, heaters, boilers, and similar systems that require dependable ignition control.
Key Features
- 120 VAC direct spark ignition (DSI) control module with microprocessor‑based sequencing for precise ignition timing.
- Three ignition tries before lockout to improve start‑up reliability.
- No pre‑purge and 15‑second inter‑purge interval to clear gases between ignition sequences.
- 10‑second trial‑for‑ignition (TFI) period for consistent spark timing.
- Single‑spark flame sensing with thermostat/power‑off reset.
- Potted multi‑pin connector design for durability in demanding environments.
- Compatible with LP, natural, and manufactured gas‑fired systems.
