I think more information is needed here.
If I understand you correctly, you have pulled out your old fireplace and you plan to install a new one. Is this a self contained unit like a "Majestic" which is now Vermont Castings.
I am assuming the new one will be going back into the same location and you will be framing the new rough opening in the area where the old hole is. Is that right?
We will await your response,Jason
