Okay--who knows how to install doors on a fireplace

[Horse with no Name]

I ran across some nice glass doors for my fireplace at the Goodwill.
I have absolutely no idea how to install them.
Any suggestions on where to start?

1. can you take a pic? usually there's a frame they sit on n/t

2. You need to find the frame

they originally fit on or a frame that will work. It's not something you can build out of wood (obviously). You might be able to get a sheet metal fabricator locally to make a frame that will work, mount hinges and doors on it yourself. Just measure the size of your fireplace, the size of those doors, and decide whether the frame has to go up against the firebox opening (the usual arrangement) or can be fitted within it.

Good luck.
