top exit horizontal termination
Simple venting configuration (only one 90° elbow)
For vent configurations requiring more than one 90° elbow, the following formulas apply:
Formula 1: H
< V

Formula 2: H
+ V
< 40 feet (12.2m)

Example:
V
= 3 ft (0.9m)

V
= 8 ft (2.4m)
2
V
= V
+ V
= 3 ft (0.9m) + 8 ft (2.4m) = 11 ft (3.4m)

= H
+ H
= 2.5ft (0.8m) + 2 ft (0.6m) = 4.5 ft (1.4m)
