Weil McLain 512-200-079 Burner

When you are troubleshooting a Weil McLain CG, CGa, or CGi boiler with ignition failures or roll-out issues, the Weil McLain 512-200-079 Burner is the specific OEM replacement burner required for a precise fit and reliable combustion. This stainless steel burner is engineered for high-temperature resistance and features an integrated spark bracket (also referred to as a pilot bracket) to ensure stable electrode positioning and consistent flame crossover. Measuring approximately 14.94 inches in length, this component is essential for maintaining the correct natural gas or propane combustion profile within the heat exchanger. Utilizing genuine Weil-McLain parts like the 512-200-079 prevents the common harmonics and delayed ignition "bang" often associated with inferior universal alternatives. Designed for professional contractors, this assembly facilitates rapid installation during routine maintenance or full manifold rebuilds to restore peak thermal efficiency and safety in residential hydronic systems.

• Direct Compatibility: Exact OEM replacement for Weil-McLain CG series boilers, ensuring proper venturi alignment and orifice spacing.
• Corrosion Resistance: High-grade stainless steel construction prevents premature oxidation and clogging of the burner ports.
• Integrated Spark Bracket: Securely holds the pilot or spark igniter in the factory-spec position for reliable light-offs.
• Optimized Combustion: Precision-drilled ports provide a stable, blue flame to maximize fuel efficiency and minimize carbon monoxide production.

Does this burner support both Natural Gas and Liquid Propane systems?
Yes, the Weil McLain 512-200-079 is designed to operate with both NG and LP fuel types, provided it is used with the correct manifold orifices for the specific gas pressure of the appliance.

Will this resolve a "delayed ignition" or "booming" sound at startup?
If the existing burner ports are warped or the spark bracket is bent, it can cause delayed crossover. Replacing the assembly with this stainless steel burner often corrects these combustion timing issues.

Is the spark electrode included with the burner?
This SKU includes the burner tube and the attached bracket. The igniter/electrode itself is typically sold separately or can be transferred if it remains in serviceable condition.
