C. 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 7.1).

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 7.1).

D. 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 7.2).

Horizontal terminations are measured to the outside mounting surface (flange of termination cap) (see Figure 6.1).

Vertical terminations are measured to bottom of termination cap.

Horizontal pipe installed level with no rise.
