Buying Guide
What model and gas line do you have?
Check your Weber grill model year, Genesis or Spirit II designation, and confirm compatibility with LP conversion hardware. Some kits target broad model families; others are more specific.
Do you need a complete kit in one box?
All-in-one kits simplify installation with regulator hose, LP orifices, fittings, and tools. If you already have some components, you may opt for a more focused option with just the missing pieces.
How important is BTU matching?
Orifices are drilled to match BTU output. Kits with multiple sizes let you fine-tune flame stability and heat distribution. Poor BTU matching can cause uneven cooking or flare-ups.
Model range and compatibility
Some kits list a wide range of Weber models; others specify Genesis or Spirit II sublines. Verify that your exact grill model is listed to avoid fit issues.
Safety and installation considerations
Follow included instructions and use the supplied sealing tape and wrenches. If you are unsure, consult a professional technician to perform the conversion.
