D. Use of Elbows
diagonal runs have both vertical and horizontal vent aspects
when calculating the effects. Use the rise for the vertical
aspect and the run for the horizontal aspect. See Figure 4.4.
two 45º elbows may be used in place of one 90º elbow. on
45º runs, one foot of diagonal is equal to 8-1/2 in. (216 mm)
horizontal run and 8-1/2 in. (216 mm) vertical run. a length
of straight pipe is allowed between two 45º elbows. See
Figure 4.4.
Figure 4.5 shows the vertical and horizontal offsets for SlP
elbows.

E. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards:
• Pipe measurements are shown using the effective length of
pipe. See Figure 11.1 for SlP for information on effective
length of pipe components.
• horizontal terminations are measured to the outside
mounting surface (flange of termination cap) (see Figure
4.3).
• Vertical terminations are measured to bottom of
termination cap.
• horizontal pipe installed level with 1/4 inch rise per foot.
