Screw the flex knob assembly onto the main tube.
20) Screw the adjustment nipple into the main tube
while watching for any movement of the lever (198).
As soon as you see any movement of the lever, stop
turning the nipple. Turn the nipple just enough so
that the lever drops 1/8 inch.

Screw the adjustment nipple into the open end of
the main tube.
Slide the main tube and associated parts into the
regulator body.
23) If the main tube assembly has been properly
installed in the regulator, the lever must be pointing
straight up so that it will make contact with the dia-
phragm at the correct point. Note that the threaded
end of the main tube where the bent tube adapter
connects to it protrudes from the regulator body.
24) The flats on the main tube should be even with
the outside end tube of the regulator body. If they are
not, gently rotate the main tube assembly until flat
surface on the main tube align with the flat surfaces
inside the tube on the regulator body.
26) Loosen the packing nut from one to one and a
half turns.
27) Install the bent tube adapter and torque to 30
inch pounds.
The end of the threads on the main tube should be
flush with the opening of the tube on the side of the
regulator body.
