Switching your Blackstone griddle from propane to natural gas is a smart upgrade if you want a steady fuel supply without needing to replace propane tanks. This guide covers everything you need to know to safely and effectively convert your Blackstone griddle to natural gas.

What You’ll Need

Tools and Materials

1. Blackstone Natural Gas Conversion Kit (specific to your model; check the Blackstone website or manual for compatibility).
2. Adjustable wrench or socket set.
3. Screwdriver (flathead or Phillips, depending on your model).
4. Drill with proper-sized drill bits (if the kit requires orifice modification).
5. Pipe thread sealant or plumber’s tape rated for gas use.
6. Soap and water solution (for leak testing).

Safety First

• Ensure the griddle is off and has cooled completely before starting.
• Disconnect the propane tank before beginning the conversion.
• Work in a well-ventilated area to avoid gas buildup.
• If you’re unsure about any step, consult a professional plumber or gas technician.

Step 1: Verify Compatibility

Before you start, confirm that your Blackstone griddle can be converted to natural gas. Most newer models are compatible, but older models may not be. Check the manual or Blackstone’s website for details.

Note: Using a conversion kit not approved by Blackstone may void your warranty.

Step 2: Purchase a Natural Gas Conversion Kit

Blackstone sells model-specific conversion kits that include:

• Natural gas hose with quick-connect fitting.
• Natural gas orifices.
• Instruction manual.

Make sure to buy the kit designed for your exact griddle model.

Step 3: Remove the Propane Components

1. Turn Off the Gas: Ensure the propane tank valve is fully closed.
2. Disconnect the Propane Hose: Use an adjustable wrench to unscrew the hose from the regulator.
3. Access the Burner Valves: Remove the griddle’s control panel using a screwdriver. This will expose the burner valves and orifices.

Step 4: Replace the Orifices

1. Locate the Orifices: These are small brass fittings at the end of the burner valves.
2. Unscrew the Propane Orifices: Use a wrench to remove them.
3. Install the Natural Gas Orifices: Replace the propane orifices with the ones provided in the conversion kit. Tighten them securely but avoid overtightening.

Optional Orifice Drilling:

Some kits may require drilling the new orifices to a specific size for optimal gas flow. Refer to the kit instructions for the correct drill bit size.

Step 5: Connect the Natural Gas Hose

1. Attach the Hose to the Griddle: Screw the natural gas hose fitting onto the griddle’s gas inlet. Use plumber’s tape or pipe thread sealant for a secure, leak-proof connection.
2. Connect the Hose to the Gas Line: Attach the other end of the hose to your home’s natural gas supply. If your home has a quick-connect fitting, this step will be simple. Otherwise, you may need a licensed plumber to install one.

Step 6: Perform a Leak Test

1. Prepare a Soap Solution: Mix water with a small amount of dish soap in a spray bottle or bowl.
2. Turn On the Gas: Open the natural gas valve slowly.
3. Check for Leaks: Spray the soap solution on all connections. If bubbles form, tighten the connections and retest until no bubbles appear.

Step 7: Test the Griddle

1. Turn on the Burners: Ignite each burner to ensure they are functioning correctly. The flames should be steady and blue.
2. Adjust the Flame: If the flame is weak or uneven, consult the kit instructions for troubleshooting. You may need to adjust the regulator or orifice size.

Step 8: Secure and Store Properly

1. Reassemble the Griddle: Replace the control panel and ensure all screws are tight.
2. Store the Propane Components: Keep the propane hose and orifices in case you want to revert to propane in the future.
