Variation on tiling fireplace surround.

Starting research for installing tile on the face of the front wall of a newly installed wood-burning zero-clearance fireplace. The manufacturer identifies a perimeter "hot zone" and specifies wire lath and non- combustible material set with Type S mortar. Looking at layered ledge stone or a ledge-stone look porcelain. I'm most comfortable setting with a modified thin set, so would like to transition away from the mortar. The tile will cover the face on the wall 65" wide from floor to ceiling. Th inset products seem to share a threshold of 250 degrees F until there is a breakdown. Hard to know surface temperatures as distance from the heating unit increase, but it is undoubtedly somewhere beyond the designated zone. Long way to ask if Type S mortar is suitable for interior vertical installation of tile.
