Weber 66306 Genesis Natural Gas Manifold Assembly

What Problem This Part Solves

The manifold distributes natural gas evenly from your home's gas supply to each burner while allowing precise flame adjustment through the control knobs. After years of grilling, heat, grease, moisture, and environmental exposure, internal valve components can wear or become damaged.

Common symptoms of a failing manifold include:

• Gas leaks around the valve stems
• Burners that won't ignite consistently
• Uneven flame height
• Low heat output
• Sticky or difficult-to-turn control knobs
• Inconsistent cooking temperatures
• Weak burner performance
• Gas odor near the control panel

Replacing the Weber 66306 restores proper gas delivery and dependable burner control, allowing your Genesis® II grill to operate safely and efficiently once again.

Frequently Asked Questions

Which grills does the Weber 66306 fit?

The Weber 66306 is designed for select Genesis® II E-210 and Genesis® II LX E-240 natural gas grills that originally used this manifold assembly. Always verify your model and serial number before ordering.

Is this manifold for propane or natural gas?

The Weber 66306 is manufactured specifically for natural gas (NG) grills. It should never be installed on a liquid propane model or used as a fuel conversion component.

Does this include the hose or regulator?

No. This product includes the manifold assembly only. The natural gas supply hose and quick-disconnect fitting are sold separately.

Is this a genuine Weber replacement part?

Yes. The Weber 66306 is an authentic Weber OEM replacement manufactured to Weber's original engineering specifications for fit, gas flow, and safe operation.

Should I leak-test the grill after installation?

Absolutely. Every gas connection should be tested with a soap-and-water solution before lighting the grill after replacing any gas-carrying component.
