Need some help identifying insert

[Sociallyacceptable15]

Hello,
I recently bought a house from my grandparents. They had a Fisher brand fireplace insert. I am able to locate the model number on the insert itself. What I am looking for is a user manual and/or recommended dimensions for if we were going to replace it with a new insert based on its dimensions.

Fisher did not use model numbers. The tag is a UL Listing Label showing it was tested by the Warnock Hersey testing laboratory.

The model is a optional “Glass and Brass” Fisher Fireplace Insert with Series III doors.

Measure original fireplace for dimensions that a replacement would fit.

Make sure this is connected to an insulated stainless steel liner extending to top of chimney. The replacement Insert will require the correct size liner as well.
