Mono Flue Chimney System

Our 16” Diameter EM 40 Universal Flue is the largest insulating masonry chimney available. With proprietary “Air-Vent” technology, it will not crack like cheaper concrete alternatives. Used exclusively for outdoor applications, it requires a 2” clearance to combustible materials.
