Need to find a burner for natural gas that works in low pressure residential home

[Zachery]

As the title says, I'm trying to find a burner that works for natural gas. The ones I'm finding all say they are for commercial use only. The flexible hose that was given to me is 3/8", so I also imagine I would need a conversion to a 1/2 inch. This is the closest I could find, but I'm still not sure.
The reviews said that there was black soot from the burning anyways, which still points to too low pressure. Anyone know of a good NG burner online?

All the bayou burners offer a NG orfice that you can swap out and then you could get a NG adapter for your standard propane adapter. Then you can use any burner you want.
