change the air/gas ratio
how do we get our gas range converted back to natural gas
If your grill was a propane grill then the short quick answer is no. The reason: the gas pressure between Natural gas and Propane is different. There are adapters available for things like fire places but I am not sure if there are adapters for propane gas grills.
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
Change out the gas flow orifice size to propane and adjust the gas valve.
Yes, there is a kit you can get to replace the orifices of the natural gas.
buy a new fireplace.
It would be very difficult to convert a solid heater into a gas.
this can be done but its not as simply as just hooking it up. you will need to change the manifold which is not always readily available. depending upon the manufacturer of the grill, you will likely need to order an L.P. (Propane) manifold directly from the manufacturer. Most propane distributors will convert natural gas appliances to LP for a modest fee. It is a matter of changing orifice sizes to let less gas into the appliance. Since propane burns about 4 times hotter than gas, an orifice which is about half the diameter is used. We had all of our gas appliances, dryer, stove, BBQ, converted when we moved from a location with natural gas to propane.
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.
switch the jets over to natural gas. get them at most hardware stores.
