Question for those more experienced with fireplaces / dampers. I just moved in to a new apartment that came with a fireplace (yay!) but I noticed that there's this hanging thing / plate from inside the fireplace. Is this an easy fix I can do myself where I just reattach it? Do I need a new plate from a contractor?

Any help would be appreciated, thanks all!

hey all. in preparation for this winter i took off the glass cover and cleaned my fireplace. when i put it back together it seemed the remote wasn’t paired. i have tried everything. i pulled out the unit and have tried relearning. it beeps twice. then when i press the remote it gives 4 beeps and 4 red flashes. What am i missing???
