horizontal termination

Simple venting confi guration (only one 90° elbow)
For vent confi gurations requiring more than one 90° elbow, the following formulas apply:
Formula 1: H < V
T
Formula 2: H + V
T
Example:
V
= 3 FT (0.9m)
1
V
= 8 FT (2.4m)
2
V = V + V
= 3 FT (0.9m ) + 8 FT (2.4m) = 11 FT (3.4m)
T 1 2
H
= 2.5 FT (0.8m)
1
H
= 2 FT (0.6m)
2
H = H + H
= 2.5 FT (0.8m) + 2 FT (0.6m) = 4.5 FT (1.4m)
R 1 2
H
= .03 (three 90° elbows - 90°) = .03 (270° - 90°) = 5.4 FT (1.7m)
O
H = H + H
= 4.5 FT (1.4m) + 5.4 FT (1.6m) = 9.9 FT (3m)
T R O
H + V
= 9.9 FT (3m) + 11 FT (3.4m) = 20.9 FT (6.4m)
T T
Formula 1: H
T
9.9 FT (3m) < 11 FT (3.4m)
Formula 2: H
T
20.9 FT (6.4m) < 40 FT (12.2m)
Since both formulas are met, this vent confi guration is acceptable.
