Installation
2. Place four
1
/4-in. (6-mm) tack welds at 90° increments. Check alignment of the
mounting both parallel and perpendicular to the axis of flow.
3. If the mounting alignment is within tolerances, finish weld per local codes. If outside of
tolerances, make adjustments prior to making the finish weld.
4. To avoid serious burns, allow the mounting hardware to cool before continuing.

Step 3: Install the isolation valve
1. Position the isolation valve onto the mounting flange. Ensure the valve stem is
positioned so that when the Flo-Tap is installed, the insertion rods will straddle the pipe
and the valve handle will be centered between the rods (see Figure 2-34).
