Clear Vista: The Villa Vista wood-burning fireplace is equipped with catalytic technology that allows the unit to burn 72 percent efficient and meet EPA Phase II emission standards. A cast-iron door with ceramic safety glass allows viewing of the firebox, and a blower redirects heat into spaces up to 2,500 square feet. An air-wash system keeps the glass soot free.
