Connecting to natural gas line

I have a natural gas grill that is attached to a pole installed in the ground and attached to a natural gas line. Can the Ducane be installed the same way?

The city where I live requires a licensed plumber to do this. So I guess my problem is solved.

Just bought a Weber Genesis II LX Model S-340 Natural Gas Grill. The plumber installed a 54' line, 1" in diameter. The grill will only heat up,to 400 degrees. What could be wrong?.

If he really installed a 54 foot line instead of a 54 inch line, the line is way to lone. The gas pressure isn't high enough to supply enough gas to the grill to get any hotter.

I have a Weber Genesis S-330. My house has a natural gas pipe out to my deck with a shut-off value. Do I need to buy a seperate part to connect the hose to the gas line? Can't seem to figure out how i

Hi Jamie Duke, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box? Did your grill come with a grey rubber gas hose and/or a quick-disconnect fitting? The quick disc. (typically 1/4", 3/8" or 1/2" size) should hook up to your shut off valve, but you may need to buy a pipe fitting to adapt to it, that is, if the shutoff valve is not the same size. Let me know if I can be of any assistance. Douglas

Was your grill originally set up for Natural Gas or did to convert it from Propane to Natural Gas? If so, where did you get the conversion kit? It may have been missing some vital parts.

If it was not a conversion, did the grill come with a natural gas regulator already installed?

Please advise... Thanks

If you have a high pressure 2lb LP Gas System feeding your house, you will need and inline regulator for you grill.

If you have Natural Gas, the grill will have to be converted to Natural Gas. You can do this by changing burner orifices. You can purchase them from Brinkman. That is, if Brinkman approves the change to Natural Gas. Some gas grills aren't convertible.

I am interested in converting my thermador outside grill from propane to natural gass. My grill is about 8 years old. how should I go about it?

Hi an welcome to FixYa. I am Kelly. I could go on and on about the how too convert it but I think you should really read this link first:

This is about the best info around.

Having passed that information on... You have the following to consider.

1. Dual shut off valves for the grill. One near by and one at some distance in case the gas line catches fire.

2. You will need a Natural Gas regulator.

3. The burner orifices will have to be changed to NG

4. The burner itself will require an air adjustment to get the proper flame. Most burners are NOT adjustable so you may have to buy natural gas burners.

5. The gas supply line has to be installed by a certified and bonded installer.

I would visit either the location that your bought the the grill or.. a BBQ grill specialty store. I have not been in one yet that did not have someone on the payroll that could help you accomplish the conversion.

Thanks for using FixYa.


It is not difficult to do.. You just have to do everything safely.

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.

Here is the link:

Jenn Air 740-0141 LP to NG Conversion

If the grill can be converted, it's usually a matter of providing a source for the natural gas and then changing the gas jets for the burner(s) and possibly a regulator, depending on your model. Some grills may require changing the gas burner valves themselves. Kits are usually available from a dealer unless the unit is old.

The natural gas jet will be slightly larger than the propane jet because natural gas doesn't have as high a heating value as propane.

If you do this, check your new conversion for any leaks using a soap solution in a spray bottle.

Just be aware that the grill may not get as hot with natural gas and cooking could take a little longer, but should still work just fine.

Your natural gas line should typically be about 1/2" unless it's huge or is over 50-60 feet away from the grill location. If so, use a 3/4" line. Piping material and methods are usually governed by your local building codes.
