Weil McLain 511-330-148 Ignitor Replacement Kit

The Weil McLain 511-330-148 Ignitor Replacement Kit is a critical OEM component designed for high-performance ignition in Weil-McLain GV, GV90+, HE, HE II, and AHE series boilers. This comprehensive hot surface igniter (HSI) kit serves as a direct upgrade for the discontinued 511-330-145 and is essential for maintaining the 200-ohm resistance parameters required by United Technologies 1013-200 control boards. Utilizing a Norton 271Y silicon carbide igniter, this assembly provides the thermal durability needed for 120V reverse combustion systems. The package includes the 590-317-599 igniter gasket and mounting screws to ensure an airtight seal within the burner assembly, preventing combustion air leaks that compromise efficiency. This genuine Weil McLain boiler part is engineered to withstand the intense thermal cycling of residential gas boilers, ensuring reliable flame rectification and consistent light-offs for veteran service contractors.

• OEM Compatibility: Precision-engineered for Weil-McLain GV90+ Series 1 and 2, HE II, and AHE gas boilers.
• Complete Replacement Assembly: Includes a factory-spec Norton 271Y igniter, high-temperature gasket, and mounting hardware for immediate field installation.
• Optimized Resistance: Designed to meet the specific electrical load requirements of Weil McLain ignition modules, preventing premature component failure.
• Durable Construction: Features a high-silica ceramic base and specialized alloy leads to resist oxidation in high-heat environments.

• Does this kit work with the GV90+ series? Yes, this is the factory-authorized ignitor replacement kit for GV90+ boilers.
• Can I use a universal igniter instead? It is not recommended; this 511-330-148 kit maintains the specific 120V characteristics and mounting alignment required for OEM burner housing.
• Why does my igniter keep cracking? Igniters are fragile; ensure the included 590-317-599 gasket is seated properly and avoid touching the carbide element with bare hands during installation.
