So as the title suggests, I'm new here and I have a bit of a laundry list of questions/concerns. Thanks in advance for reading and for any advice you can give 
My husband and I just moved into a new rental house. It has a natural gas fireplace that I'm guessing is older because it doesn't have a pilot light, or any controls. The only way to control the flow of gas is the key on the wall. The fire burns way more on the right side than the left. A lot of soot seems to be developing on the inside bricks and the logs. There's a rust colored residue forming on the grate and bottom pan. The tube that the gas comes out of seems really off center as well. I feel like there is something (or many things) wrong here, and it makes me nervous to use the fireplace. I have googled and googled to no avail, and we can't really afford to have someone come look at it (plus... covid). Any help is most appreciated! I'll attach some photos as well.
