B. Use of Elbows

Diagonal runs have both vertical and horizontal fl ue as-
pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect (see
Figure 5.1).
Two 45º elbows may be used in place of one 90º elbow. On
45º runs, 30.5 cm of diagonal is equal to 21.6 centimeters
horizontal run and 21.6 centimeters vertical run. A length
of straight pipe is allowed between two 45º elbows (see
Flue diagrams).
