Installing a "new" Blazeking KTJ302 ... its from 1977-1983, but only burned ~1 cord b4 being retired to storage. I'm going to use it in my wood shop, on a wood subfloor in a wood framed wall, alcove. Trying to determine good set backs/clearances for this pre epa model stove. I plan on installing a tile hearth onto cement backerboard and corrugated sheet metal sides and back, onto cement backerboard. Trying to properly interpret the NFPA (211) guidelines for clearances applicable to this model stove. Can anyone guide me to this info? The owners manual only details clearances to combustibles, not non combustibles.
