Fenwal 35-665913-119 Module
The Fenwal 35-665913-119 is a sophisticated 24VAC microprocessor-based gas ignition control designed for precise combustion management in commercial and industrial HVACR applications. This direct spark ignition (DSI) module features a 15-second pre-purge period to ensure the combustion chamber is clear of residual gases before the ignition sequence initiates. Engineered for reliability, this Fenwal ignition module utilizes a multi-trial for ignition logic, providing three trials for ignition to prevent nuisance lockouts in demanding environments. The 35-66 series control is built with a ruggedized design to withstand heavy-duty cycles, making it a critical replacement furnace control board or boiler ignition module for heating systems requiring a 100% shut-off safety lockout function. Its compact footprint and standardized wiring terminals facilitate direct field replacement, ensuring minimal downtime during critical service calls. This HVAC control module delivers consistent spark energy to ensure reliable burner light-off across varying pressure and gas flow conditions.
Key Benefits for Technicians- Microprocessor Control: Delivers precise timing for pre-purge, inter-purge, and ignition trial sequences to optimize burner efficiency.
- Safety Lockout: Features a robust 100% shut-off mechanism that immediately terminates gas flow if flame rectification is not sensed.
- LED Diagnostics: Includes onboard troubleshooting indicators to rapidly identify system faults and reduce diagnostic time on the job site.
- Direct Compatibility: Form-fit-function replacement for specific Fenwal 35-66 series models, utilizing standard 1/4-inch quick-connect terminals.
- Flame Sensing: High-sensitivity remote flame sensing circuit ensures stable operation even with marginal flame signals.
What is the purpose of the 15-second pre-purge on the 35-665913-119?
The 15-second pre-purge is a safety requirement that allows the inducer fan to evacuate any unburned gas from the heat exchanger before the spark electrode is energized, preventing delayed ignition or "rumbling" starts.
Can this module replace a single-trial ignition control?
While functionally similar, replacing a single-trial unit with this three-trial ignition module provides additional attempts to establish a flame before hard lockout, which is often preferable in environments with fluctuating gas pressure or cold starts.
How do I troubleshoot a 'No Spark' condition with this Fenwal module?
First, verify 24VAC at the input terminals. If power is present, inspect the high-voltage cable and spark electrode gap. Ensure the module is properly grounded, as Fenwal DSI controls require a solid chassis ground for successful flame rectification.
