This Burnham Commercial Ventilation System, known as the Concentric Vent Termination (VNT), is a specialized component designed for use in commercial heating and cooling systems. It is constructed from high-quality, durable materials to ensure longevity and reliability. The VNT functions by facilitating the efficient expulsion of exhaust gases from a heating system while simultaneously drawing in fresh air for combustion. This dual functionality is achieved through its unique concentric design, which features an inner exhaust vent surrounded by an outer intake vent. The system has been engineered to minimize heat loss during operation and reduce the risk of backdrafts, enhancing overall system efficiency and safety. The Concentric VNT is compatible with a range of Burnham Commercial heating systems, offering flexibility for various installation requirements.
