Insert Help...any suggestions appreciated!

I recently got my hands on a vintage wooden fireplace frame for the purpose of fitting it with a ventless gas insert. I've been looking at ventless firebox inserts, but they are all too large it seems.

The opening for the box is 23"wide by 20"tall. I haven't found a single box even close to these dimensions. Does anyone know where I could acquire a box roughly this size?

I would never put a ventless fireplace in my home. Too many bad byproducts from combustion.

I put one in my Utah house as an emergency back up 15 years ago. I never use it.
