Example C:
17ft vertical rise / 1 90˚ elbow / 5ft horizontal
Use restrictor setting No.2.
Maximum horizontal elbows
allowed - 3
Note: if more than 1 90˚ elbow is used hori-
zontally the maximum horizontal is reduced
by 1ft.
Example B:
If to reach the desired termination at point ‘B’
you use 2 90˚ elbows, you would be required
to reduce the maximum horizontal to 8ft.
If 3 90 ˚ elbows were used to reach point ’B’,
the maximum horizontal would be reduced to
7ft.
Maximum Vertical - 35ft
Maximum Horizontal - 20ft with 7ft minimum rise
