TOP AND REAR EXiT vERTiCAL TERMiNATiON
Simple venting configurations.
For vent configurations requiring one or more 90° elbows (top exit) or one or more 90° elbows
(rear exit), the following formulas apply:
Formula 1: H
< V
T
Formula 2: H
+ V
T
Example:
V
= 5 FT (1.5m)
1
V
= 6 FT (1.8m)
2
V
= 10 FT (3.1m)
3
V
= V
+ V

+ H
= 8FT (2.4m) + 2.5FT (0.8m) = 10.5FT (3.2m)

H
= .03 (four 90° elbows - 90°)
O
= .03 (360° - 90°) = 8.1 FT (2.5m)

+ H
= 10.5FT (3.2m) + 8.1FT (2.5m) = 18.6FT (5.7m)
