Weil McLain 511-330-079 Ignition Module

Upgrade your system restoration with the Weil McLain 511-330-079 Ignition Module, a critical component for maintaining precise sequence control in CGA Series gas boilers. Engineered as a direct OEM replacement ignition control, this module (model UT-1107-2) operates on a 120V power supply to manage consistent spark-to-pilot ignition cycles. Designed for professional HVAC contractors, it replaces failing boards in residential hydronic systems to resolve boiler short cycling or ignition lockout issues. The integrated safety controls and solid-state construction provide stable flame monitoring, ensuring the main gas valve only opens upon verified pilot presence. This intermittent pilot ignition module is calibrated for seamless integration with existing wiring harnesses in Weil McLain hydronic boilers, delivering localized flame rectification that maximizes system uptime and reduces nuisance service calls.

• Direct Compatibility: Specifically engineered for Weil McLain CGA boilers of all sizes, ensuring a perfect drop-in fit for the UT-1107-2.
• System Reliability: Features solid-state construction to withstand the high-temperature environment of boiler cabinets for superior longevity.
• Reliable Safety Logic: Provides consistent spark ignition with built-in safety shutoff to prevent hazardous gas accumulation.
• Simplified Installation: Designed for standard 120V boiler ignition control module wiring, streamlining field replacement and troubleshooting.

• What causes a Weil McLain boiler to lockout on ignition? Common causes include a faulty 511-330-079 ignition module, a fouled pilot burner, or a degraded flame sensor that fails to send a rectification signal.
• How do I verify if my UT-1107-2 module is defective? Technicians should check for 120V input at the module and verify that the spark occurs during the trial for ignition; if power is present but no spark is generated, the module typically requires replacement.
• Is this module compatible with other Weil McLain series? This specific part is primarily cataloged for CGA boilers; always verify the part number on your existing board before installation.
