Seal Plate Assembly
Step 1. Install wax ring seal plate and connection brackets.
A. Place two new T-bolts into the slots on the floor outlet
flange.
B. Install the wax ring onto the underside of the wax ring
seal plate, then press the seal plate down evenly and
firmly over the T-bolts and floor outlet flange.
C. Place the flange connection “L” brackets onto the
T-bolts then attach the washers and nuts to the T-Bolt (see
illustration).
D. Align flange connection brackets to the sides of the
seal plate (see illustration) then tighten the nuts
until snug to seal the wax ring to the floor outlet flange.
Note: This mounting assembly assumes your floor outlet
flange is proud of, or even with your flooring. Recessed
flanges may not seal correctly and leakage is possible.
Additional sealing may be necessary in this instance.

T. The flush button is pre-assembled and
adjusted at the factory, but may require proper
alignment and adjustment of the flush rods
upon installation.
First position the lid so that it is aligned where
it will sit in its final resting position, then check
to make sure the button assembly also aligns
correctly with the actuators on the flush valve.
If adjustment is needed, loosen the button
locknut and reposition. Retighten the locknut.
Second, make sure the tip of the push rods
lightly touch the top of the flush valve buttons.
To increase or decrease rod length, first loosen
the rod locknut, then adjust the threaded rod to
the desired length. Retighten the locknut to
secure the rod.
