Hi all - I ended up picking up one of these ( cannot return ) thinking I could convert it to Propane, as there are plenty of blogs out there saying this can be done with conversion kits from Weber. However, after talking with a tech at Weber, she thought it was not possible with this model, as they stopped making kits last year. I won't know until I get the serial numbers to really know. However, I thought I would check here to see if anyone else might know - even if it can be done w/o a Weber kit.

Thanks - Dan

I have the previous model, which I did convert from NG to Propane. The only way to go is a Weber kit. Good Luck.

As weber doesn't sell the conversion kits anymore, due to liability issues, you have 2 options. 1. get a plumber or other certified person out to your house to run a gas line to an area where you can use the grill. 2. sell the grill on ebay or Craigslist and buy yourself one that works for you. People are selling these pretty frequently on those two sites, and you may have some luck. You're not going to get what you paid for it, but you can get something, which you can put towards a new one that works....for you. I just bought a brand new Weber off of Craigslist today.

Converting from Natural Gas to Propane is simpler than from Propane to Natural Gas.
To convert NG to LP you simply need to by an adjustable Regulator to increase the Water Column from 7" (NG uses) WC to 11" (LP uses). There is no need to change the orfice. You need a device that reads the correct Water Column. Any HVAC can do that for you. If Weber doesn't sell the Kit anymore than go to a Professional Propane Outlet and explain your need, they most likely can sell you the required regulator. You may need additional fittings.

From LP to Natural gas requires you to reduce WC from 11 WC to 7 WC and make the orfices larger. If you have an exact size drill bit, you can do it yourself. Get professional advice at any LP supplier, not a gas station but a Commercial House. The above is to my best recollection per various web sites. Please verify the above information with a Professional LP Repair & Supply House. This posting is solely meant to make you aware that conversions are possible. Always contact a professional before you play with Natural & LP Gas.

This does not sound right. NG jets have big holes, LP jets have small holes. If you leave the big NG jets in place and also raise the pressure you will get way too much flow. To do it this way you will want to keep the pressure low and adjust it by observing the flame.

another point, I think NG is normally regulated to 2" wc

I have a one year old Propane Weber 310 that I want to use with NG. I wonder if there's a way we could trade devices?

We have a two-year old NG Weber Genesis 310 that we can't use anymore after moving to a house with no gas line outside. We're in Oakland, CA. If you're nearby, a trade might be awesome.
