How do I convert natural gas to propane

You'll need to change out the burner orifices, (propane orifices require smaller holes), add a propane regulator and hose (these can be bought as a combo) along with a 20# propane cylinder. I would recommend taking it to your local propane dealer that sells grills and see if they can help you with either the parts or the conversion itself.

How do I convert from liquid propane to natural gas

You need parts from the manufacturer. The gas orifices are different sizes between natural gas and LP gas. If you try natural gas with an LP gas orifice, you will not get much flame. If you use LP gas with a natural gas orifice, you will burn off your eyebrows and possibly other things.

I would like to convert a grill that was used on natural gas back to propane. Can I just purchase a regulator and hose and be good, or do I need to change anything else on the grill?

Burner orifices must be resized or adjusted to accommodate higher pressure LP.
Air shutters should be opened all the way to allow maximum air to gas ration.

Convert from Gas to Propane - I had this grill converted by a plumber from propane to gas (I believe he changed the nozzles and added a gas line instead of the propane line). I've had to move the...

The "nozzles", as you called them are actually the burner orifice. If you remove the burners and look back into the control panel, you should see the orifices that the plumber installed. They unscrew with a nut driver to be removed. Do this one at a time, installing the LP Gas Orifice immediately after removing the Natural Gas one. Be careful not to mix them up and reinstall the Natural Gas ones.
You will also need a LP Gas Regulator/Hose Assembly to connect to the grill tank, that you will be using. You can pick one up at any hardware store or home improvement center that sell grills & accessories. It runs about $30.00.

Below is a link to the Owner's Manual. But, I'm not sure it will be of help in changing the orifices. But, it's good to have for future reference. You can download and print it.

I hope this helped you and Happy Grilling!! Thanks for choosing FixYa.

I need to convert my weber genesis b to nat. gas. Have the hose. bought a replacement manifold part and installed but doesnt seem to work. STEVE 269-600-8111

Steve, you also need to change the burner(s) orifices to Natural Gas orifices. Natural gas won't work with Propane orifices.

Good luck and Happy Grilling!!

Broilmaster P3 series (purchased circa 2001). Just replaced burner, ignitor and converted from Propane to Natural. Fired the thing up and it appears to flame (difficult to see), but it just won't warm...

If you didn't change the burner orifices to Natural Gas orifices, that's the problem. Even after those are changed (assuming you didn't) the grill will take a bit longer to preheat. As Propane burns cleaner and hotter than Natural Gas, in an outdoor environment.

Hope this helped answer and solve the problem for you.

How to change a weber natural gas grill to propane

According to Weber, "There is no conversion kit available to convert any Weber gas grill from one gas type to another. Any attempts to do it will void your warranty."

Sorry, but if it's any consolation, Propane Gas burns cleaner and hotter that Natural Gas in an outdoor environment. Which translates into faster preheating and hotter searing temperatures.

Hop e this helps and happy Grilling!!

Converion kit to natural gas.

I don't believe Weber makes a gas conversion kit for your model grill. I say this, because your model grill comes two ways, Natural Gas or Propane. This indicates to me, that there's more than just changing the burner orifices involved.

I can tell you this ... If you could convert it to Natural Gas, you would soon discover that the grill doesn't preheat as fast as with propane. Nor, will it maintain heat as well as propane, in an outdoor environment. Propane burns cleaner and hotter than Natural Gas in an outdoor environment.

Sure, it may seem like a hassle to refill and change the tank, but I can assure you, you won't be satisfied with it's performance.

Converting Thermos Stainless Grill to natural gas

You have to install a conversion kit for it to work the way you want. The reason is because the orifice in either the valves or the main "jet" that feeds the burner tube has to be changed. Natural gas is really not as efficient as lp gas (propane) because it takes more natural gas to create the same btu output as propane.

In short, your grill will not work if you do not do the conversion. I am including a link that lists the conversion kit for your grill, you can order it there and you can download the assembly manual as well.

I have a Sunjoy patio heater that uses propane and I want to convert it to natural gas. Is there a hose kit, and do I need to change the orifice. Richard

You will have to change the orifice for sure, but you have to get an orifice that works with the valve on the heater. Check with the manufacturer and see if there is a conversion kit, it is the only way to make sure that you make all the necessary changes to the unit. If there is not a conversion kit available, I would recommend that you not do it.
