Laars Heating Systems E2313900 Ignition Module
The Laars Heating Systems E2313900 Ignition Module is a critical 24V electronic ignition control engineered for precision sequence timing in natural gas boilers. Designed for professional field replacement, this module features a 3-try, 4-second trial for ignition (TFI) protocol, ensuring safe burner startup and flame rectification. As a direct OEM replacement part, it replaces obsolete and legacy controls, including part numbers 35-679920-571 and 35-679928-561. This module manages the pilot and main burner valves while providing the necessary high-voltage spark for intermittent pilot ignition systems. Built for high-duty cycles in residential and light commercial hydronic applications, the E2313900 ignition control maintains system integrity by preventing gas buildup through its rigorous safety lockout timing. For contractors servicing Laars equipment, utilizing this genuine Laars replacement ensures exact electrical connector alignment and mounting footprint compatibility, reducing diagnostic time and installation labor on-site.
Key Benefits for the Technician
- Direct OEM Compatibility: Ensures seamless integration with existing Laars boiler wiring harnesses and factory bracketry.
- Standardized Sequence: Features 3-try ignition logic to minimize nuisance lockouts during cold starts or low gas pressure scenarios.
- Enhanced Safety Timing: The 4-second TFI windows are calibrated to meet stringent combustion safety standards for natural gas heating systems.
- Broad Cross-Reference: Consolidates inventory by replacing multiple Fenwal 35-67 series and legacy Laars ignition boards.
Common Questions
Is this module compatible with LP gas systems?
The E2313900 is specified for natural gas boilers. Verify the specific manifold pressure and gas valve requirements of your equipment before attempting use on propane applications.
What does the 3-try, 4-second TFI signify for troubleshooting?
It indicates the control will attempt to light the burner three times, providing a 4-second spark window for each attempt. If flame sensing is not confirmed via the flame rectification circuit, the module will enter safety lockout.
Does this replace the Fenwal 35-679920-571 specifically?
Yes, the Laars E2313900 is the designated replacement for 35-679920-571 and 35-679928-561, maintaining the same electrical parameters and terminal configurations.
