VERTICAL TERMINATION
Simple venting configurations.
For vent configurations requiring one or more 90° elbows the following formulas apply:
Formula 1: H
< V
T
Formula 2: H
+ V
T
Example 6:
V
= 5 FT
1
V
= 6 FT
2
V
= 10 FT
3
V
= V
+ V
+ V
= 5 + 6 + 10 = 21 FT

+ H
= 8 + 2.5 = 10.5 FT

H
= .03 (four 90° elbows - 90°)
O
= .03 (360° - 90°) = 8.1 FT
H
= H
+ H
= 10.5 + 8.1 = 18.6 FT
