Consequently, can I use natural gas orifice for propane?

Natural gas is fed at a smaller pressure than propane, so to get the same heating value (usually measured in BTUs), a natural gas orifice has to be smaller than a propane one. This suggests that you can convert a natural gas appliance to a propane one and vice versa by changing the orifice on the gas valve.

Additionally, is natural gas orifice better than propane? The reason for this is because natural gas orifices are larger than propane orifices strictly because of gas service pressure. Conversely, trying to use a propane appliance with natural gas will likely result in a very small flame or no burner flame at all because of the lower pressure gas and the smaller orifice.

Also to know, how much does it cost to convert from propane to natural gas?
