how do we get our gas range converted back to natural gas
to do this you switch it from natural gas to propane remove this answer, a tautology, no help at all
I am wondering if you can convert the lp or propane gas to natural gas on a bosch tankless hotwater heater. I am guessing it has a different orfice and regulator
Yes, there is a kit you can get to replace the orifices of the natural gas.
It would be very difficult to convert a solid heater into a gas.
Change out the gas flow orifice size to propane and adjust the gas valve.
buy a new fireplace.
You can't convert natural gas to propane because natural gas is methane and propane is what it says it is. Given that, there are Compressed Natural Gas cars, and if you get a natural gas compressor you can use it in a car.

YOU cannot - you need to call a gas fitter.
There should be a conversion kit, ask the saleperson where you purchased it..
Go to your local hardware store and ask for an orifice to convert your stove from natural gas to propane. I am sure a salesperson will tell you how to install it if it doesn't come in a package with instructions.
switch the jets over to natural gas. get them at most hardware stores.
