Do you have a make/model tag?
If specifics aren’t available, you could use an installation guide for a modern okeefe and merit stove.
My little suburban gave a couple useful numbers: at least 9 inches from center if burner to a combustible surface, at least 18” clearance above a burner.
Use black iron pipe to plumb to the stove. On my installation I piped into the manifold compartment with black pipe. The connection from pipe to the manifold Should be done with 3/8” copper tubing that is flared to 45 degrees and is connected with flare fittings and flare nuts.
Have you already run gas pipe?
