Genesis C1 3-burner LP manifold assembly

This Weber manifold assembly is a direct replacement part for Genesis C1 three-burner grills configured for liquid propane in the US and ZA markets. It restores the original gas distribution to the burners so the grill performs as designed. The part is supplied new and sold individually. It is not intended for natural-gas models or for Genesis series grills with a different burner count.

Normal-use thermals noise and power

The assembly is a passive metal component with no moving parts, electrical connections or fuel consumption of its own. It simply channels gas from the regulator to the burner tubes, so it generates no heat, noise or power draw beyond what the grill itself produces during cooking. No additional energy supply or ventilation is required for the part itself.

Build quality and day-to-day fit

Constructed from factory-specified materials to match the original equipment, the manifold aligns with the mounting points and burner inlets on compatible Genesis C1 units. The barbed and threaded connections accept the stock regulator hose and burner tubes without adapters, allowing a straightforward swap during routine maintenance. It fits model numbers 61060001, 61010001, 61010201 and 61000001 only.

Questions about this item

How do I install the Weber 66303 manifold assembly on my Genesis C1 3B LP grill, and what step is commonly missed?

Turn off the LP supply, remove the control panel and burner tubes, then unbolt the old manifold; the step often missed is re-seating each burner tube fully over the new orifices before tightening the panel screws.

What maintenance or replacement will the Weber 66303 manifold assembly need over time?

Inspect the brass orifices annually for blockage or corrosion and replace the manifold if gas flow becomes uneven; the LP hose and regulator should also be checked every season for cracks or leaks.

What limit appears first on the Weber 66303 manifold assembly during sustained high-heat grilling?

The brass orifices can carbonise under prolonged LP flare-ups, causing uneven flame patterns before the manifold body itself shows any distortion.
