Switching from propane to natural gas can save refills and let you cook for long gatherings without interruption.

Will this kit fit my BlackStone griddle or burner?

Compatibility covers a range of BlackStone appliances but excludes some specific models. This kit is designed for BlackStone 28-inch and 36-inch griddles, Tailgater and Rangetop Combos, and single-burner recreation stoves. It is not compatible with the BlackStone AirFryer Griddle Combo or the 22-inch griddle.

• Includes 16 natural gas orifices to match burner ports.
• Adapters and thread-check gauges (M6×0.75 & M6×1) to confirm proper thread size.
• Check appliance manual and connection type before purchase.

How safe and durable is the hose and fittings?

The 10-foot natural gas hose is built to outdoor standards and certified for safety. It meets CSA/ANSI Z21.54 and CSA 8.4-1Q/25 requirements, confirming pressure integrity and leak resistance for outdoor gas hoses. Brass connectors and a three-layer hose design provide corrosion resistance and mechanical strength for regular backyard use.

• CSA C‑US certified (No. 265442) for outdoor hose safety.
• Three material layers: weather-resistant PVC, cotton braiding, flame-retardant inner tube.
• Solid brass quick-connect fittings with rubber dust caps to prevent contamination.

What hardware and tools are included, and how easy is installation?

The kit arrives as a fully equipped package so you won’t need additional parts for a standard conversion. BlueStars supplies a 10-foot hose with quick-disconnect ends, multiple adapters, 16 natural gas orifices, an orifice wrench, and two thread-check gauges. Three illustrated manuals walk you through identifying threads, swapping orifices, and attaching the hose for a straightforward installation.

• 10-foot hose with 3/8in male quick-disconnect plug and 3/8in female flare.
• 3/8in female quick-connect to 3/8in female NPT adapter and M6 thread gauges.
• 7mm orifice wrench and 16 orifices to tune each burner port.

What performance should I expect after conversion?

When installed correctly, the kit supports continuous natural gas cooking and higher run-time convenience compared with propane cylinders. The hose is rated for up to 50,000 BTU/hr with a maximum working pressure of 1/2 PSI, which suits most residential griddle and burner setups. Keep in mind that final flame characteristics depend on correct orifice selection and regulator setup.

• Flow capacity: 50,000 BTU/hr; max pressure: 1/2 PSI.
• Includes assorted orifices so you can match burner needs for balanced flames.
• Lifetime protection from BlueStars covers manufacturing defects.
