Buying Guide
What to consider when choosing a propane-to-natural-gas conversion kit:
- Model compatibility: Ensure the kit explicitly supports your grill’s model family (Weber Genesis, Spirit, Spirit II, Genesis II, etc.).
- Hose length and regulator: Longer hoses reduce move-around limits, and a regulator helps maintain steady gas pressure.
- Orifice options: Multiple orifice sizes ensure BTU matching and flame stability for different grills and fuels.
- Fittings and accessories: Look for included wrenches, tape, and quick-connect fittings for easy install and a leak-tight seal.
- Safety and certification: CSA or other certifications indicate compliance with standard safety practices for gas connections.
- Installation complexity: Some kits require precise hole drilling or model-specific fittings; assess whether you’re comfortable with DIY installation.
