VERTICAL TERMINATION
Simple venting configurations.
f i r e - p a r t s . c o m
For vent configurations requiring more than one 45° and one 90° elbow, the following formulas apply:
Formula 1: H
< V
T
Formula 2: H
+ V
T
Example:
V
= 5 FT
1
V
= 10 FT
2
V
= V
+ V
= 5 + 10 = 15 FT

= H
+ H
= 3 + 2.5 = 5.5 FT

H
= .03 (one 45° + three 90° elbows - 135°)
O
= .03 (45 + 270 - 135°) = 5.4 FT
H
= H
+ H
= 5.5 + 5.4 = 10.9 FT
