For vent configurations requiring one or more 90° elbows the following formulas apply:
Formula 1: H
T
< V
T
Formula 2: H
T
+ V
T
< 40 feet (12.2m)
Example:
V
1
= 5 FT (1.5m)
V
2
= 6 FT (1.8m)
V
3
= 10 FT (3.1m)

= 5FT (1.5m) + 6FT (1.8m) + 10FT (3.1m) = 21FT (6.4m)
H

= 8 FT (2.4m)
H
2
= 2.5 FT (0.8m)
H
R
=
H
1
+ H

= 8FT (2.4m) + 2.5FT (0.8m) = 10.5 FT (3.2m)
H
O
= .03 (four 90° elbows - 90°)
= .03 (360° - 90°) = 8.1 FT (2.5m)
H

H
R
+ H
O
= 10.5FT (3.2m) + 8.1FT (2.5m) = 18.6FT (5.7m)
H
T
+ V
T
= 18.6FT (5.7m) + 21FT (6.4m) = 39.6FT (12.1m)
Formula 1:
H
T
< V
T
18.6FT (5.7m) < 21FT (6.4m)
Formula 2:
H
T
+ V
T
< 40 FT (12.19m)
39.6FT (12.1m) < 40FT (12.2m)
Since both formulas are met, this vent configuration is acceptable.
