The Vent Control System (VCS) maintains a constant negative pressure in the exhaust common manifold or individual chimney/vent. Designed with EC-Flow Technology™, the VCS takes advantage of US Draft Co. bi-directional pressure transducer and proprietary PID technology to rapidly respond to varying manifold or individual system pressure on Category I, II, III & IV as well as building heating appliance systems. Utilizing the Truline™ inline or termination draft inducer, a VIC series control and pressure transducer, the system interlocks with fossil fuel fired heating appliances to maintain the required outlet pressure of the manufacturer. The VCS meets all requirements for the National & International Fuel Gas Codes and the Uniform & International Mechanical Codes.
