Hi, new guy here. Owner of various Weber grill over the time (and occasional char-broil that went to trash after a week:)).
My current one is old Genesis, but recently i picked up ex-335 genesis ii smart grill. Story goes it got burned up, and the dude got it with an intent to fix from his client, but it was too much work. So yes, free for me...it was NG, so i will be doing the conversion to propane.
I do read a lot before bothering people, but instill have a few questions. Pretty much all the igniter wires are gone, as well as knobs. Cook box is warped at the bottom.
So far i fixed and painted the box, very small crack, but it works and accepts pan. All electronics work fine. I will be replacing the manifold to LP one.
Questions - tank scale, i think i can get any latest that accepts tank sensor, not specific genesis ii?
Burner tubes - same part number on all 4 for np. Lp are different parts, makes a difference and what is it? Maybe move spider covers a bit to adjust?
Gas regulator, i think i can get any weber model one?
I have an ocd and im pretty sure it will work fine without the tank scale or lighted up knobs, but i have to make it right:)

Burners are burners. IDK why except maybe to make things more "scary" or difficult for anyone who wants to do this. But a burner does not care what the fuel is (NG or LP), only that it is metered correctly. Since you will change the manifold and regulator to proper type fuel supply you will not have any trouble and no adjustment should be necessary. As for acquiring the necessary parts not sure what to tell you there. Others here are far more in the know
 
I agree burners are burners and adjust airflow identically once the proper nozzles are installed on the valves. It really comes down to size of the hole in that valve tip, and maybe not necessary to replace the entire manifold. I have rescued similar mode grills some NG and some LP so I've been able to swap things around for what i wanted for for a particular grill. The hole size for NG is larger than LP. On one grill I thought was LP, but was really a NG partially converted by added a LP regulator, once lit had 12 inch or so flames! Your probably best off to go ahead and swap out that manifold. Best of Luck.
 
I also thought that only orifices can be swapped, but apparently the valves inside are different as well..so new manifold is coming my way.
Also i bought a cheap igniters with wires, but looks like they are the same as weber sells for replacements, they got pink wires and no cups, that go into the igniter module.
I just need to find the right orifice for side burner, it is different size thread than others
 
Thanks, I will check out check out that tread ,this is great information. There are lots of conversion kits online that don't mention this. It certainly can be confusing, Why I said best to change the manifold.

It's not confusing if you come here and communicate with folks who've actually been through the wringer on it. Weber has gone out of their way to not only make it "hard" to convert but actually a bit dangerous to do it willy nilly with liers and crooks on YouTube and FleaBay
