It looks like cast iron from the pics. And that would make sense that it would rust with a little rain. It should really be stainless and brass in our climate. Here's a picture of what they are using for mine.
That looks like a log lighter ???

They're cast iron. If they heavy castings it will be a l o n g time before it has any affect on performance. I'd be more concerned on whether or not your fire pit has a drain of some sort. You don't want it filling up with rain water.

. They are doing that tomorrow and we can't use the vacuum yet. [emoji37] Not looking forward to that since we're still stepping on loose pebble. Can't use the manual yet either because it has wheels.I love our Dolphin. It's a M400. No idea how that compares to the other model mentioned - but we love it! Just toss it in and hit the power button and in a couple hours it stops. I reverse the handles each time I get it out - our builder said that would prevent it from getting in a "rut" of a pattern, or something. Honestly I don't know, but we love it! I've yet to manually vacuum the pool. And we also just got our spray deck done and let me tell you - that dust was a MESS! Thank goodness for the robot.
. We have one on the covered patio. I'm hoping it's close enough. [emoji51]. I think it will be. We have one on the back side of the bond beam if not but I'd rather not have to plug it in over there.I have the m500 and I like it a lot. The filters are removed from the top and are super easy to clean. I just drop Mr. Robot into the pool, push the button and in about 2 or 2.5 hours he's done. The only hard part is hauling him out of the water. He also comes with a caddy, but maybe all Dolphins do.

Did you install an outlet close to your pool?
