Hi, all. New to the forum and new to Weber grills. My old CharBroil hit the landfill last week and I decided to treat myself to a Weber Genesis E-310. It's a pretty copper colored model that I purchased from Lowes. It just arrived and, much to my surprise, it was already assembled. That's both a good and a bad thing. Good because it saved me the time of assembly, but not so good because building it is the best way to get to know it. That said, I have a few basic questions, so please excuse my ignorance. . .
1) I haven't fired it up yet, so I'm wondering if there is a "break in" or first time use procedure I should follow?
2) The grates are cast iron. Do these need to be conditioned in the way a cast iron skillet does?
3) Inside the cabinet attached to one of the doors is a hanging chain. I don't see any reference to this in the manual. Can someone tell me what it's for?
4) I'm curious about the ignition. I know it runs on a battery which was already installed. Just wondering, to replace the battery do I simply pull the knob off? That's what it appears like in the manual.
Thank you!
