Duct Connections

Installation of all ducts should be done in accordance with SMACNA and AMCA guidelines.

Connect primary exhaust air ducts to unit using flanged connections. Screw ducts directly to unit using stainless steel self-tapping sheet metal screws. Contractor is responsible for providing transitions to accommodate difference in sizing between unit and building ducts. Duct connections to collar-type openings can be made with S-cleats or overlapping joints. Apply caulking around the duct connection. Failure to ensure a tight fit and properly seal duct connections can cause air leakage and system performance problems from the contaminated airstream.
