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 floor flange 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 differ-
ent heights, the floor flange must be mounted within
3/8 inch (10 mm) of the bottom of the toilet (see il-
lustrations in next column) or leakage may 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.
