gas fireplace operations

I have a gas fireplace that I have never used before (and never used a fireplace before). I have a screen but I don't see anywhere to install it. How do I attach the screen for use and is it necessary for a gas fireplace?

Also, there is a knob below the door (circles in the first pic). As I understand it, this opens the damper but when I look up into the chimney it is not doing anything. The fireplace has a door more like the second pic and I can open and close it from inside. What does this knob do?

Thank you in advance.

On gas fired fireplace the screen is just decorative. It was used on wood burner to prevent sparks from flying out onto you rug or floor surface.

That knob, again no longer used, but a decorative piece. The flue should be opened.

Does that gas "fireplace" have a pilot light or do you just have a gas lighter for real wood ?
Manual flue dampers and gas appliances don't go well together.
The pilot requires a flue for exhaust gases and leaving a manual damper open is extremely wasteful.

The knob on the bottom screen looks like an adjustment/damper for fresh air into the fireplace.
Can't tell how well sealed that front panel is.

I think a screen is now code on gas fireplaces. According to Consumer Reports it was mandated on gas fireplaces in 2015. Models built before that often had just a glass front and there were lots of burn injuries, especially small children.

However, your install to be typical fireplace doors that may pre date your gas burners.
