Horizontal sections require a ¼” (6mm) rise every 12” (305mm) of travel.
•
A maximum of four (4) 45° or 90° elbows may be used. Of these elbows, only one (1) may be a
horizontal elbow (see illustration).

The termination must fall within the shaded area shown in the chart. Use the indicated restrictor
and diffuser position. NOTE: Restrictor positions are based upon lab tests. The ideal restrictor
position may vary slightly, especially when the termination is near a demarcation line.
