Connect Outlet Duct to Home Vent Duct
Circular ridged ducting with minimal bends is recommended for best air flow performance. A 4”, 5” or 6” circular ridged
duct is needed to connect to the duct adapter as shown in Figure 6. Install the circular ridged duct and secure it with
clamps or ties, and seal it with mastic or approved duct tape.
