Typically placed perpendicular to flow in each appliance’s connector, a barometric damper can offload up to 0.3″W.C. The use of a modulating damper can reduce fuel consumption by 10% or more when installed in individual appliance connectors.Ī barometric damper is a device designed to offload natural draft by introducing dilution air into the chimney or gas vent. The multi-blade damper-actuator may be used with any type of chimney or gas vent, including special gas vents, and may be placed in the common manifold or in individual appliance connectors to comply with the NYC’s Department of Environmental Protection. A modulating damper system is specified to manage and maintain a constant draft for single or multiple boilers, water heaters, and other Category I, II, III or IV heating appliances. modulating dampers, consist of a controller, pressure transducer, high speed actuator and multi-blade damper. ![]() There are two types of draft control:įor your specific project, please contact our design team to discuss. The control has an integrated safety system to assure the heating appliance will shut down in case of fan failure or control failure. Draft control is recommended when chimneys or gas vents generate natural draft in excess of the appliance manufacturer’s draft requirements. The control will allow continuous or intermittent operation of a mechanical draft fan. ![]()
