A 2’ (610 mm) vertical section must be installed
before any offset. A maximum of 20’ (6.1 m) horizon-
tal and three (3) 90° elbows may be installed with a

Up to two (2) 30° or 45° elbows may be used within
the horizontal run. For each 30° or 45° elbow used
on the horizontal level the maximum horizontal
