BBQ Conversion Kits: Switch Your Grill from Propane to Natural Gas
Step-by-step guide to converting a propane BBQ to natural gas — what the conversion kit contains, how long it takes, tools required, and safety checks before lighting the grill.
What Is a BBQ Natural Gas Conversion Kit?
A natural gas conversion kit replaces the propane-specific parts of your grill — the regulator, hose and burner orifices — with natural gas equivalents. After conversion, the grill connects to a permanent natural gas line instead of a propane tank, so you never run out of fuel mid-cook.
What the Kit Includes
- Orifices: one per burner, sized for natural gas
- Regulator: natural gas regulator, typically 7 WC
- Hose: natural gas rated hose with quick-connect
- Instructions: model-specific steps and torque specs
Tools You Need
Most conversions need a screwdriver set, an adjustable wrench, and thread sealant rated for gas (yellow PTFE tape or pipe dope). Some grills need a socket set to remove the burner assembly.
Step-by-Step Conversion
- Turn off the gas and disconnect the propane tank completely.
- Remove the grates and burner covers to access the burners.
- Remove each burner orifice with the correct wrench and replace it with the natural gas orifice from the kit.
- Replace the regulator — the propane regulator is removed where the tank connected, and the natural gas regulator is installed in its place.
- Replace the hose with the natural gas hose supplied.
- Check for leaks: brush soapy water over every new connection with the gas on — bubbles indicate a leak.
- Test fire each burner at low and high settings, checking for even blue flames.
Safety Checks Before First Use
After conversion, inspect the flames. A healthy natural gas flame is blue with a small inner cone. Yellow flames mean incomplete combustion — check the orifices are the right size and the air shutters are adjusted. If you smell gas at any point, close the supply valve and do not light the grill.
Can You Convert Back to Propane?
Yes, keep your original propane parts. Reversing the process and reinstalling the propane orifices and regulator returns the grill to propane use. Never mix parts from different brands or models — orifices are specific to the burner design.
