PRODUCTPROPERTIES
Distancefromtherimtothewatersurfaceis4-7/8”.
2-1/4” passageway.
For roughing-in and overall dimensions, see
Fig. #1.
Fixture dimensions are nominal and conform to
tolerances by ANSI standards (A112.19.2).
PRODUCTREQUIREMENTS
Since all toilets do not have the same supply
rough-in, you may have to change the location of
the supply stop to install this toilet.
Closet flange must be 12” on-center from wall.
Seat post holes are on 5-1/2” centers.
This toilet is designed to flush using 3.5 gallons
when the tank refill time is adjusted to between 50
and 55 seconds. Tank refill time is measured from
the moment the flapper ball reseats to the time
water stops flowing through the refill tube. Slightly
longer refill time may be necessary to compensate
forpermanentortemporary low waterpressure.To
adjust the refill time, see “To Adjust Refill Time”,
on Page 5.

ALIGN AND SET TOILET
Carefully align and lower the toilet over the closet flange
and T-bolts.
CAUTION: Risk of external leakage. Donot lift or
rock the toilet after placement. A new gasket must
be reapplied if you break the watertight seal.
Apply full body weight to the toilet rim to set the seal. Fig. #5
SECURETOILET
Assemble the bolt cap bases, washers, and nuts on the
exposed T-bolts.
CAUTION: Risk of personal injury or product
damage. Overtightening may cause breakage or
chipping.
Hand tighten the nuts, then tighten them an additional
1/2-turn with a wrench. If the T-bolts extend more than
1/4” from the top of the nut, cut off the excess with a
hacksaw, and file the cut edges. Wipe away any residue.

Makesure thethreetankboltsextend completelythrough
the holes in the gasket. Set the tank onto the bowl, using
the tank bolts as a guide. Center the gasket on the inlet
of the bowl. Assemble the washers and brass nuts onto
the bolts.
Alternately tighten the three brass nuts so the top of the
tank and the top of the bowl are both level. Be sure the
brass nuts are tight enough to achieve a watertight seal.

CHECK FOR LEAKS
Turn on the shut-off valve, and check for leaks. If the
connections are squarely assembled, a slight re-tighten-
ing of the nuts will stop any leaks. Check all connections
for leaks for several days. The nuts under the bolt caps
may also require retightening.
