For vent confi gurations requiring more than one 45° elbow and 90° elbow, the following formulas
apply:
Formula 1: H
T
< 4.2 V
T
Formula 2: H
T
+ V
T
< 24.75 feet (7.5m)
Example:
V
1
= 4 FT (1.2m)
V
2
= 1.5 FT (0.5m)
V
T
= V
1
+ V
2
= 4 FT (1.2m) + 1.5 FT (0.5m) = 5.5 FT (1.7m)
H
1
= 2 FT (0.6m)
H
2
= 1 FT (0.3m)
H
3
= 1 FT (0.3m)
H
4
= 1.5 FT (0.5m)
H
R

1

+ H
4
= 2FT (0.6m) + 1FT (0.3m) + 1FT (0.3m) + 1.5FT (0.5m) = 5.5 FT (1.7m)
H
O
= .03 (one 45° elbow + four 90° elbows - 135°) = .03 (405 - 135°) = 8.1 FT (2.5m)
H
T
= H
R
+ H
O
= 5.5 FT (1.7m) + 8.1 FT (2.5m) = 13.6 FT (4.2m)
H
T
+ V
T
= 13.6 FT (4.2m) + 5.5 FT (1.7m) = 19.1 FT (5.8m)
Formula 1: H
T
< 4.2FT (1.3m) V
T
4.2FT (1.3m) V
T
= 4.2 FT (1.3m) x 5.5 FT (1.7m)= 23.1 FT (7m)
13.6 FT (4.2m) < 23.1 FT (7M)
Formula 2: H
T
+ V
T
< 24.75 FT (7.5m)
19.1 FT (5.8m) < 24.75 FT (7.5m)
Since both formulas are met, this vent confi guration is acceptable.
