Newbie here....I am working on installing a wood insert. I failed my measuring and due to the firebox tapering in, I can't get the insert pushed back all the way. Is there any reason I can't remove the firebrick? If the firebrick is necessary, is there a panel on the market that can be cut to fit and put in to save me space? Thx!

You need 8" of masonry between that insert and any combustible material If you have that with out that fire brick you can if you don't then no you cant
Install manual says to set insert 14" into firebox. I can only get it pushed back about 11". Not enough to get the liner attached. I pulled a firebrick out on one side to take some measurements. Entire fireplace is 52" wide (outside) and continues into the basement where it also measures 52". When I measure the inside of the firebox to the firebox opening and compare it to the overall width it seems that there is about 10" of space between the firebox (without firebrick) and the outside of the whole fireplace. Sorry if that's confusing.....
I'm not picturing your setup here. When you say firebrick are we actually talking firebrick or just a clay brick fireplace? I've never seen a fireplace built with firebrick. Is this going into a prefab fireplace? What insert are you installing? Any pics?
Edit: Another question....Is this an exterior chimney? Might make a difference if the brick you cut is beyond the wall or interior to the house

Sorry for the confusion, hard to explain. Here are some pics. I have already removed the firebrick on the side I am measuring. From the reads on the tape measure I have 12" wide minus the 3" return inside the firebox. 9" thick on the side, correct?

what do you mean almost all the masonry fireplaces i see are fire brick.
You cannot go by the face brick that does not tell you much about the thickness of the brick around that firebox. You need to do some more investigation. We have simply drilled into the sides at times wit ha long masonry bit to check the thickness.
Well fire brick are required by code for the last 30 or so years so yes they should be. Are you sure you are not just seeing red firebrick? I cant beleive that many are built out of common brick anymore.
As far as the measurement the face of the fireplace really tells you absolutely nothing about what the structure behind there is. They almost always extend past the structure
