• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is reduced
by 36" (914 mm) Figure 22. This does not apply if the
90° elbows are used to increase or redirect a vertical
rise. Figure 23
According to the vent graph (Page 15) the
maximum horizontal vent length in a system with a 7.5'
vertical rise is 20’ (6 m) and if a 90° elbow is required in the
horizontal vent it must be reduced to 17' (5.2 m).
In Figures 22 and 23, Dimension A plus B must not be
greater than 17' (5.2 m).
