CALCULATE THE DUCT RUN LENGTH
The ductwork length should not exceed 35 equivalent VENTINGRIGHT
feet for 3-1/4" X 10" duct, or 60 equivalent feet for 9"
round duct, Calculate the length of the ductwork by FIG.03 Ducting
adding the equivalent feet listed in Fig.04 for each piece
of duct in the complete system, An example is given in Fig. 05. For best results, use no more than
three 90° elbows, Make sure that there is a minimum of 24" of straight duct between elbows if more
than one is used, Do not install two elbows together. Round duct is recommended instead of
rectangular duct especially if elbows are needed, Rectangular duct should transition to round as soon
as possible (d"round minimum),
