Example a) Example b)
0' 18' 21'
1000' 18.72' 21.84'
2000' 19.44' 22.68'

3) Add 4% overall for each 1000' above sea level.
Example: a)
1-1/2 ft. of horizontal run = 3 ft.
one "T" = 3 ft.
Total Addition (at sea level) = 6 ft.
Example: b)
One 90 deg. elbow = 2 ft.
2 ft. of horizontal run = 4 ft.
one "T" = 3 ft.
Total Addition (at sea level) = 9 ft.
Simple rules on draft (refer to Table 1).
1)
At sea level minimum height is 12' straight.
2)
Add the following vertical height to compensate for:
45 deg. elbow = 1 ft.
90 deg. elbow = 2 ft.
"T" = 3 ft.
Each foot of horizontal run = 2 ft.
