    2) Whats different about the side burners (LP vs NG)? Will an LP side burner unit connected to an NG manifold work OK?

    The part numbers for the burner tubes, and the side burner unit appear to be different for LP and NG.

    I intend to retain the LP components for any future reconversion.

    Thanks.

    (Just joined the forum so excuse me if I've inadvertently violated any rules/etiquette)
    1) I did not change the burner tubes. The manifold swap alone is enough.
    2) You just need the right orifice for the side burner. I am not sure if you can find a replacement part online. I can take some measurements to see if the ones grill-parts sells fits (PM me or I won't remember). Otherwise I would just drill it out with a #54 bit. You can try w/o any modification and like LMichaels said you will just get a small flame. I don't know how important is the side burner to you but most people don't use it.

    The NG hose is also a direct swap.

    Just FYI, the LP valves are cast aluminum and the NG valves are brass. So, the valves are indeed different between the LP and NG versions.

    That material difference you noticed may have just been a production difference from the factory in China where the assembly is made. Really has nothing to do with NG or LP

    The side burner is not such a big deal for me, Ill try and get the correct orifice for the NG side burner if this is a cost effective solution otherwise I'm not too bothered.
    Its good to know the main and sear burner tubes are approximately equivalent.

    Which parts did you order?
    I think it's
    (4) 88305
    (1) 88315
    (1) 80012
    But a confirmation or correction would be helpful
    I'm looking to switch over a 2012 Genesis EP-330 from NG to LP

    Andrew - Did you buy the parts from grill-repair? I'm about to purchase the same myself and was wondering how your conversion turned out.

    The side burner conversion is easiest because it has a variable (not fixed) type valve. So really a simple orifice change is all that's needed

    Hi LM, you recommended the full side burner unit for $110 previously in the thread. Would you recommend just ordering the orfice from Grill-Parts.com for the side burner instead now? It doesn't look like Grill-Parts will drill the orfice for you unless you're purchasing a regulator otherwise it just comes blank.

    Also, I had 2 more questions if anyone else can help?

    1. Do you have to remove the "burner bolts" in the back when installing a new manifold? I imagine so but just wanted to confirm. It seems like the guy at Grill-Parts broke all 4 of his bolts/thread block they screw into and had to JB weld it back together. Image is below. I definitely do not want to go down that road on an $800 grill. This leads into my second question...

    2. Has anyone personally broken any of the "burner bolts" when converting their Weber from LP to NG? I have an EP-330 (2011-2012) which appears to be inferior quality (at least bolt-wise) to the 2010 and previous models according to Grill-Parts.com.

    Thanks in advance!

    I have said earlier. Converting the side burner is easy because they all have the fully variable control valve rather than fixed L M H settings. Simpy change the orifice to match the gas and the pressure your gas is at.
    Re, the bolts I don't have a clue what you're talking about. Lots of rambling there. If you're converting a newer style front control panel Genesis I believe the control panel comes cover comes off than the manifold complete with valves and orifices and a simple change out of the orifice will do the job. Those grills also have continuously variable valves so it should be as easy as falling off a rock. But than I have not looked at one since I put my sister and brother in law's together about 7 years ago. I do recall how disappointed I was that pretty much every part of it was made in China, I also have cooked on it and frankly am not impressed with it. They have the E310 NG model BTW

    You should avoid doing anything with the bolts that hold the burners. Think of them as “guides” not something to loosen or tighten. Just clean a little and tug the old burners out when needed and then put the new ones in to the same place.

    If your burners are ok, you shouldn’t need to remove to replace the manifold anyway.

    Yah, those mounting screws on the end of the burners are not supposed to be removed. They are just there to hold the tubes in place. To remove the burner tubes, you have to remove the manifold and then pull the burner tubes out of the right side of the cook box through the holes. If you twisted one of the screws off, you will have to drill out the old one and then use a new screw that is slightly larger than the hole. It isn't that big of deal, just take your time. If you happen to slide off to the side of the old broken screw when trying to drill it out, that is OK. Just put the new screw in there. It will be off about 1/16" but that is no big deal. Been there, done that.
    Grills and guns are a lot alike. While one would usually suffice and you can only use one a time, each grill/gun is better in certain situations.
