Buying Guide: Key Considerations For Choosing A Propane-To-Natural-Gas Conversion Kit
What should you check before buying a conversion kit?
- Grill compatibility: Confirm the kit explicitly supports your grill model and size. Some kits are targeted to Blackstone or Weber lines and may not fit other brands.
- Hose length and fittings: Ensure the hose length fits your outdoor setup and that the quick-connect and NPT fittings match your grill’s inlet.
- Orifices and BTU matching: Look for a kit with multiple orifices or clearly stated BTU matching; this helps maintain consistent flame and temperature control after conversion.
- Safety features: CSA or equivalent certifications on hoses and components add safety assurance and compliance with standards.
- Included accessories: A complete kit with wrenches, tape, thread gauges, and mats can reduce the need for extra purchases and simplify installation.
- Model-specific restrictions: Some kits exclude certain sizes or models (for example, 22″ or 1902 Blackstone griddles). Verify exclusions to avoid returns.
Installation And Use: Practical Steps
Read the included instructions before starting. Check all connections for leaks using a soapy water solution after assembly. Ensure the natural gas supply is off during installation, then gradually test the regulator and flame stability. Maintain ventilation and follow local codes for outdoor gas installations.
Performance Considerations
Natural gas typically delivers a different BTU profile than propane. Choose a kit with multiple orifice sizes or a well-mocumented BTU matching plan to maintain even heat across griddles and grills. Properly sized orifices help prevent flameouts and provide steady sear temperatures.
