Buying Guide: LP To Natural Gas Conversion Kit Considerations

• Regulator and hose: Ensure the included regulator and hose length are appropriate for your setup and that materials meet local safety standards.
• Orifice sizing: Precise LP orifices are essential for BTU matching and flame stability. A kit with multiple orifice sizes helps match your appliance’s needs.
• Fittings and tools: Look for kits that include all necessary fittings, wrenches, tape, and installation instructions to avoid extra trips to the hardware store.
• Safety and certification: Prefer CSA/UL-listed components and clearly labeled safe-use instructions to reduce leak risk and ensure proper operation.
• Installation impact: Consider whether you can safely perform the conversion yourself or if professional help is recommended, especially for fixed gas lines.
