Buying Guide
What should you consider when choosing a propane-to-natural-gas conversion kit?
- Grill compatibility: Confirm model numbers and configuration to ensure the kit’s orifices, hoses, and regulators fit your exact grill or griddle.
- Hose length and fittings: Longer hoses offer flexibility but can introduce pressure drop. Ensure 3/8″ fittings or the specified size match your connection point.
- Orifice sizing: Hand-drilled orifices are sized for BTU output. Match the correct sizes to your grill’s burner ratings to avoid flame instability.
- Regulator presence: A regulator helps maintain consistent gas flow. Look for a kit that includes or accommodates a regulator for stable performance.
- Safety features: CSA or equivalent certifications and high-quality brass fittings reduce leak risks and improve longevity in outdoor conditions.
- Installation complexity: Some kits require drilling or specific tool sets. Choose a kit whose installation you can complete safely, or hire a professional if needed.
