Converting between propane and natural gas
Converting an appliance means modifying it to use a different fuel, usually by replacing the gas orifices, burners or regulator. Natural gas is supplied at a much lower pressure than propane, so the parts are sized differently:
- Propane in a natural gas appliance: the larger natural gas orifice lets too much higher-pressure propane through, creating an oversized, unsafe flame.
- Natural gas in a propane appliance: the smaller propane orifice and lower gas pressure produce a weak flame or none at all.
That’s why conversions must be done by a licensed gas technician with the manufacturer’s conversion kit. It’s common when natural gas reaches a rural property, or when moving a propane appliance to a home with natural gas.
