Thick Wall Installation For Walls Thicker Than 1/4 inch

3.4The“ThickWall”installation method is used when the tub/shower wall is greater than 1/4 inches thick. “Thick Walls”are usually built up with materials such as cement board, drywall, tile, etc. The valve is secured by straps (not included) holding the water inlet lines to the framing members (2X4’s) as shown in steps 2.1 and 2.2. The valve also features mounting holes to screw the valve to a cross mem- ber attached behind the valve if desired.

Attach the plaster ground (E) to the valve body using the 2-3/16 inches escutcheon screws (G). Keep the plaster ground (E) attached to the valve until the valve has been positioned and secured. The plaster ground (E) is positioned so that it is flush with the fin- ished wall. This ensures that the valve will be at the correct position to accept the trim.

The hole in the wall should be the same size (4-1/2 inches) as the plaster ground (E). This hole will allow access for future servicing if necessary.
