Sequence Draft Control^®

Fully engineered venting systems for multiple boilers

You pay a premium for high-efficiency boilers and water heaters to save energy and money. But to maximize your draft control management, you also need the right venting system.

Sequence Draft Control (SDC) prevents excess draft and maintains the desired condensing dew point of combustion. With SDC, you get exhaust flow optimization, helping guarantee maximum venting efficiency along with easy installation, lower energy consumption and increased boiler life.
