See graph to determine the required vertical rise V
T
for the
required horizontal run H
T
For vent confi gurations requiring more than two 90° elbows
the following formulas apply:
Formula 1: H
T
< V
T
Formula 2: H
T
+ V
T
< 40 feet
Example 4:
V
1
= 9 ft
V
2
= 6 ft
V
T
= V
1
+ V
2
= 9 + 6 = 15 ft
H
1
= 3 ft
H
2
= 2 ft
H
3
= 1.5 ft
H
R
= H
1
+ H
2
+ H
3
= 3 + 2 + 1.5 = 6.5 ft
H
O
= .03(four 90° elbows - 90°)
= .03(90 + 90 + 90 + 90 - 90) = 8.1 ft
H
T
= H
R
+ H
O
= 6.5 + 8.1 = 14.6 ft
H
T
+ V
T
= 14.6 + 15 = 29.6 ft
Formula 1: H
T
< V
T
14.6 < 15
Formula 2: H
T
+ V
T
< 40 feet
29.6 < 40
Since both formulas are met, this vent confi guration is
acceptable.
