ﬂange.

Turn off the water supply.

2. Mark the Installation

Remove the gasket from the waste tube.

Tilt the toilet, attach the 4″ D. waste tube, and move the toilet

into the installation position. The waste tube and waste outlet

should be engaged.

IMPORTANT! If there is a ﬂange and the ﬂoor ﬂange sits above the

ﬁnished ﬂoor, check for proper ﬁt with the base of the toilet. If the

base of the toilet does not ﬁt over the ﬂoor ﬂange you will need to

cut or grind (depending upon the ﬂange material) the ﬂange to

allow the toilet to install properly.

Make sure there is a 1″ (2.5 cm) gap between the back of the toilet

and the wall.

IMPORTANT! Make sure the toilet is correctly positioned before

marking installation location.

Trace the base of the bowl on the ﬂoor.

Remove the waste tube and toilet, and set aside.

Cut the template along the outside line with a scissors.

Mark the Installation (cont.)

Lay the template on the mounting location, matching the outside

edge with the line on the ﬂoor.

If there is a ﬂange and the holes marked on the template overlap

the ﬂange, you will need to either cut or grind (depending on the

ﬂange material) the ﬂange until the holes can be drilled into the

subﬂoor

Use masking tape to hold the template in place.

Drill two 9/16″ holes, 1-1/2″ (3.8 cm) deep minimum, at the

locations marked on the template.

3. Install the Toilet

CAUTION: Risk of back injury. Because the toilet is heavy

and awkward, two people should move the toilet into place.

Reinstall the gasket to the waste tube.

Tilt the toilet to one side and install the waste tube.

Position a support block under each side of the toilet to raise the

base 3″ (7.6 cm) off the ﬂoor. The blocks should be positioned so

the supply hose can reach the supply when the toilet rests on

them.

Wet the gasket thoroughly with soapy water or O-ring lubricant.

Insert the provided foam block into the gap between the waste

tube and the surface above it. This will provide support to keep

the waste tube from shifting while inserting the waste tube into

the waste outlet.

Connect the supply hose to the supply stop and bring it up

through the opening in the bowl, to be connected with the ﬁll

valve, when installing the tank.

Install the Toilet (cont.)

With a partner, carefully lift the toilet up and remove the support

blocks.

Hold the toilet over the waste outlet and carefully lower it into

place, making sure the waste tube slides into the waste outlet.

IMPORTANT! If the waste outlet and waste tube are not properly

aligned, the waste tube may shift, resulting in leaks.

Check the toilet for proper operation.

Position the tank on the bowl, aligning the carriage bolts with the

corresponding holes in the bowl and running the supply hose

through the corresponding hole.

Thread the two supplied bolts into the bowl through the bolt

holes in the bottom of the tank.

Slide a metal washer and rubber washer onto the bolts.

CAUTION: Risk of product damage. Overtightening may

cause breakage or chipping of the vitreous china.

Tighten the bolts using a screwdriver. Do not overtighten.

Turn the water on (There is a shut-off valve in the toilet tank that

should already be in the closed position. Turn it off if the tank

begins to ﬁll) and check for leaks.

5. Install the Floor Bolts

Make sure the plastic anchor on the end of the bolt is relaxed and

not expanded.

Carefully run the bolt through one of the seat holes near the basin

of the toilet.

When the end of the bolt is properly positioned, the top of the

bolt will seat ﬁrmly in the hole, slightly below the level of the

toilet. If the bolt sits higher than the toilet, it is not properly

seated in the ﬂoor.

Repeat with the second bolt.

Using the provided hex wrench, evenly tighten each bolt until the

toilet is ﬁrmly held in place (conﬁrm by trying to rock the toilet).
