Description
The Fenwal 35 705500 005 is a high performance 120 VAC direct spark ignition (DSI) control module designed to provide reliable burner ignition and flame sensing for gas fired heating systems and combustion applications. Its microprocessor controlled logic and built in diagnostics ensure precise sequencing, repeatable ignition performance, and safer operation in a wide range of gas burner equipment.
Key Features
- Direct spark ignition control for natural gas, propane (LP), and manufactured gas applications, eliminating the need for a standing pilot light.
- Designed for standard 120 VAC operation (102–138 VAC, 50/60 Hz) with robust current handling.
- Microprocessor based timing and ignition sequencing for consistent starts and safer combustion cycles.
- Ten second Trial for Ignition (TFI) with a single ignition attempt before lockout.
- No pre purge and no inter purge required, simplifying ignition logic.
- Built in LED diagnostics help identify system status and troubleshoot faults quickly.
- Detect A Flame flame sensing technology improves safety by confirming flame presence before continuing operation.
- Conformal coating for moisture resistance and reliable performance in tough environments.
