Converting a propane BBQ grill to natural gas can save money, eliminate tank refills, and give you endless grilling power. However, it must be done safely and correctly — not every grill can be converted, and using the wrong kit or fittings can be dangerous.

Safety Warning

Before starting any conversion, confirm these critical points:

• Check manufacturer approval. Some grills are not convertible and can only use propane. Using the wrong gas type voids warranties and risks explosion.

• Use an official conversion kit. Always get a natural gas conversion kit from the grill manufacturer — it includes correctly sized orifices, valves, and fittings.

• Verify local codes. Many regions require a licensed gas fitter to make the connection to the household line.

• Turn off all gas supplies before starting work.

If you’re unsure, contact a qualified gas technician.

Tools and Materials You’ll Need

TopGrill Outdoor gas systems are designed with quick-connect fittings that make conversion easier while maintaining leak-free performance.

Step-by-Step Conversion Process

Step 1: Check if Your Grill Is Convertible

• Find the model number and serial tag (usually on the back panel or inside cabinet).

• Visit the manufacturer’s website or manual to confirm if a natural gas conversion kit is available.

• If not, do not attempt conversion — the regulator and burner design may not support natural gas pressure safely.

Step 2: Shut Off the Propane Supply

• Turn off the propane tank valve completely.

• Disconnect the tank and remove the hose/regulator assembly from the grill.

Never attempt conversion while the system is under pressure.

Step 3: Remove the Old Orifices

• Take off the control knobs and front panel to access the burner valves.

• Locate the brass orifices at the end of each valve — these control the gas flow to burners.

• Using a wrench, carefully unscrew and remove the propane orifices.

• Replace them with natural gas orifices included in the conversion kit.

Natural gas requires more volume but lower pressure — that’s why the orifices must be larger.

Step 4: Replace the Regulator

• Remove the propane regulator (usually attached to the hose).

• Install the natural gas regulator from the conversion kit or connect directly to a household quick-connect fitting (if the grill model supports it).

• Use yellow gas tape or sealant on threaded joints.

Step 5: Connect to the Natural Gas Line

1. Mount a quick-connect fitting to the outdoor gas outlet.

2. Attach the natural gas hose from the grill to the fitting.

3. Secure all joints tightly with a wrench.

Most modern outdoor kitchens (like TopGrill Outdoor systems) use 304 stainless steel gas lines and quick couplers, ensuring durability and easy disconnection for maintenance.

Step 6: Leak Test

• Mix dish soap with water and brush it onto all gas connections.

• Slowly open the gas supply valve.

• Watch for bubbles, which indicate a leak.

• If you find leaks, close the valve, tighten fittings, and test again.

Alternatively, use a commercial gas leak detector spray for more precision.

Step 7: Test Burners and Adjust Flame

• Light the grill and check the flame pattern:

• Proper natural gas flame should be steady, mostly blue with yellow tips.

• Weak or noisy flames may indicate incorrect orifice installation.

• Adjust the air shutters (if available) to fine-tune the flame.
