Install the Valve Stem Adapter (cont.)
If the mark or your finger is below the edge of the plaster
guard, perform the remaining steps:
Slide the pencil along the steps until the mark or your fingers are
even with the top edge of the plaster guard.
Note which area of the plaster guard the pencil is touching.
If the pencil is touching the step labeled "1," use the 1-3/8" (35
mm) (medium wall) valve stem adapter and the 1-3/4" (44 mm)
screw.
If the pencil is touching the step labeled "2," use the 1-7/8" (48
mm) (thick wall) valve stem adapter and the 2-3/8" (60 mm)
screw.
If the pencil is touching the step labeled "3," use the 7/8" (22
mm) (thin wall) valve stem adapter and the 1-3/8" (35 mm)
screw.
Remove and discard the plaster guard.
Place the spline adapter over the valve stem.
Set the correct valve stem adapter over the valve stem. Do not
completely press or thread the valve stem adapter into place
until instructed to do so.
