1. Insert a length of pipe in two inch, 3,000 lb. threadolet
fitting.
2. Plumb the vertical center line of the fitting and trace
around the fitting to locate center line of required
2.62 inch (67 mm) diameter hole. Refer to Figure 5.

3. Clean up inside edges of hole, and remove any slag on the
bottom of line that could interfere with vane.
4. With fitting concentrically positioned over the 2.62 inch
(67 mm) diameter hole, and the vertical center line held
plumb (refer to Figure 6), tack weld the fitting at four

equally space points. After tacking, remove .06 inch
(2 mm) diameter spacer wire. Refer to Figure 5.
NOTE: A hole in the pipeline less than 2.62 inches (67 mm) in diame-
ter will limit travel of the pivoted vane. If this condition cannot
be avoided, the width of the vane should be reduced to
1.50 inches (38 mm) maximum.

IMPORTANT: For installation in 2.00 inch pipe lines,
disregard 2.62 inch (67 mm) dimension and
use inside of threadolet as template.
5. Proper operation of the F10 depends upon the vertical
center line of the 2" NPT coupling being plumb within
3°. Keep fitting plumb while welding the continuous
passes, according to threadolet manufacturers installation
procedure.
2.3.1.2 Positioning Vane Perpendicular to Flow
1. With large and small vanes unassembled, tighten the
F10 body bushing into the coupling on the pipeline,
until one of the three decal flow arrows is pointing
parallel with flow.
2. Mark the bushing thread, even with the top of the thread-
olet, as a reference point for trimming vane to correct
length. Remove two arrows not parallel with the pipe.
3. Remove the F10 from pipeline.
