ALL OUTLET CONFIGURATION EXAMPLE
ASSEMBLY WITH 1 90° ELBOW
For a horizontal exhaust where Vt is between 6 in.
and 16 in we have Ht < 4'
Vertical rise
V1 =0.5 feet.
Horizontal run
H1 =4 feet.
Total vertical rise
V
= 0.5 feet
t
Horizontal equivalent of elbows
H
= 3 feet (for a 90°elbow)
e
N= 1 (qty of elbow)
H
= (N - 1) x H
C
Total horizontal run
H
= 0 ft. + 4 ft. = 4 ft.
t
0.5 < vertical rise < 1.33 ft.
0.5< 0.5pi < 1.33pi
Because 0.5ft. < V
Total distance H
4 ft. + 0.5 ft. = 4.5 ft.
4.5 ft. < 40 ft.
This assembly is accepted.
40
= 0 x 3 feet. = 0 feet.
e
< 1.33 ft. use H
< 4 ft.
