This Burnham Commercial Ventilation System, known as the Concentric Vent Termination (VNT), is designed to facilitate the efficient expulsion of combustion gases from commercial heating systems. The system features a concentric design, meaning it has an inner exhaust pipe for waste gases and an outer intake pipe for fresh air, both sharing a common center. This configuration reduces the number of wall or roof penetrations needed, thus minimizing potential leakage points. The Burnham Commercial VNT is made from durable stainless steel to withstand harsh weather conditions and resist corrosion over time. It also includes a built-in bird screen to prevent wildlife intrusion into the ventilation system. The product is compatible with various models of Burnham Commercial boilers and heaters, providing a comprehensive solution for effective ventilation in commercial settings.
