STEP 5a: For through-the-floor water line and electrical
wires, mark
another centerline 6 inches (152 mm) from the
back wall (fig. 4).
STEP 5b: For through-the-wall water line and electrical
wires, mark a centerline 8 inches (203 mm) up from the
floor centerline (fig. 5).
STEP 6: Make a 4-3/4 inch (121 mm) diameter hole (for
most floor flanges) or a 5-1/8 inch (130 mm) diameter hole
(for swivel joint floor flange) at the centerline mark furthest
from the wall. Make a 1 inch (25 mm) hole at the mark
closer to the wall for the water line and electrical wires
(fig. 6).
STEP 7: Insert floor flange into larger hole and secure to
the floor with #12x3/4-inch long flat head wood or sheet
metal screws (fig.7).

IMPORTANT: The prefered installation method is to
mount the floor fIange directly on the finished floor.
However, if the bottom of floor flange and bottom of
china toilet must be mounted at different heights,
the floor flange must be mounted within 3/8 inch (10
mm) of the bottom of the toilet (see illustrations in
next column) or leakage will result.

STEP 8: Route 1/2-inch (13mm) PEX tubing through the
smaller hole and install a PEX 1/2-inch MPT fitting (fig. 8).
NOTE:
A water shut-off valve should be installed in the
water line to the toilet for maintenance requirements.
