+ V
= 1.5 + 1 + 5 = 6.5 FT

H
= 10.75 FT

H
= .03 (four 90° elbows + one 45° elbow - 90°)
O
= .03 (360° + 45° - 90°) = 6.75 FT
H
= H
+ H
= 12.75 + 6.75 = 19.5 FT

Formula 1:
H
< 3 V
T
T
3 V
= 3 x 6.5 = 19.5 FT
T
19.5 = 19.5
Formula 2:
H
+ V
< 40 FT
T
T
26 < 40
Since both formulas are met, this vent configuration is acceptable.
