Beside broken. This is in the basement of our mid-seventies built house. Since we're soon moving into a retirement community I'd like to just replace the unit and leave the metal frame in place after cleaning it and painting it. The frame is in the concrete. I just don't know where to start looking. There is a window well on the outside that feral cats sometimes sleep in during the winter. We have a wood burning stove in this room and I need to open the window to get the proper draft to start the stove. Thanks for your help. Sorry about no photos:
