The CDS2 Connector Draft System maintains the required pressure (negative or positive) at the individual appliance connector. Designed with EC-Flow Technology™, the CDS2 takes advantage of the US Draft Co bi- directional pressure transducer and proprietary PID technology to rapidly respond to varying pressures at the appliance on Category I, II, III & IV as well as building heating appliance systems. Utilizing a single blade damper (SB), pressure transducer and the internal controller, the system interlocks with the fossil fuel fired heating appliance to maintain the required outlet pressure of the manufacturer. It also serves to protect the boiler from flue gas recirculation when used in a common vent system.
The original CDS revolutionized how controlling draft is done, now with second-generation CDS2 continues with it’s all-new V-series internal controller with easier access buttons. The CDS2 is effective in all designs; individual or common vent as well as both natural draft and mechanically induced systems. The CDS2 changes how you design your venting system.
