Yes and the gas works for all of those! We have turned the knobs here and even tried lighting a lighter and nothing happens.

Do you have other gas appliances? Do you have a tank in your yard or are you on city gas?

hopefully if someone abandoned those gas lines they disconnected them or there is a shutoff elsewhere. Leaving such a situation as a live gas line with an easily accessible valve is a disaster waiting to happen . Trying to light an unknown gas

orfice with a match is also a recipe for a potential disaster.

Typically, those handles are removable simply by pulling them off. Until you get this figured out, I suggest you put the handle where a child can't get at it.

Is that a log lighter, i.e., are there holes along that pipe?

Call a licensed plumber to check it out and reconnect (if disconnected) if that's what you want.

Plumbers in my state aren't allowed to do gas lines anymore.

Wow. I think only plumbers are allowed to do black pipe work in mine.

Take a look at that pipe and see if there are holes drilled in the top. If there are holes, its like the gas starter that came with my fireplace. With a gas starter you first turn on the gas, hold a match against the holes to turn on the starter flame, and then it starts your logs on fire.

If the gas is not coming on with the handle mounted in the wall, there is a shutoff somewhere else that is stopping flow. When they installed my gas starter they had the wall shutoff like yours, but had to put a 2nd shutoff within so many feet. Mine was inside a base cabinet adjacent to the fireplace. In my current house the gas line goes down from the fireplace to a utility room, and the 2nd shutoff is in the basement below. Not easy to find if you don't know where it is.

Who is allowed to handle gas lines will vary from state to state. AFAIK, in my area you need a gas fitter license, and the person is usually also a licensed plumber.

If you can trace back the gas pipe going towards the meter you will likely find a shut off valve that is closed, or maybe the previous owner disconnected the pipe. You could turn on the shut off yourself, but it is best to call in a plumber to verify the piping is sound and not leaking.

If you want to use the fireplace, then I suggest you install a fireplace log. Turning on a gas pipe and trying to light it is dangerous if you are not good at it. The log as a built in ignitor and a adjustment valve. It would also look nicer.
