Locate power lead and factory connection to

Acceptance of this application must be verified by the local inspector or authority having
jurisdiction (AHJ).
STEP 3.10:
Shower Application
1. Refer to diagrams in the Appendix, especially pages 26 & 27.
2. Never install TapeMat or ShowerMat in shower walls (or any other wall).
3. Never make a field splice to mats installed in a shower.
4. It is recommended that a dedicated mat be installed in the shower area, separate from
the mat in the rest of the floor. In case there is ever a problem with the shower installation,
this mat could be disconnected without loss of heat to the rest of the floor.
5. Use the double-sided tape or hot-glue to secure the ShowerMat. Do not use staples or
anything that will damage any waterproofing membrane.
6. If the heating wire must enter the shower area over a curb, secure the wire at the edges
in an "s-shaped" curve to ensure the wire is not bent sharply or pinched when surface
coverings are installed. Do not damage any waterproofing components, and do not run
the heating wire through a non-masonry curb, causing it to overheat.
7. Embed mats in mortar and install only under tile, stone, brick, or other masonry surface,
per this instruction manual.
8. Never begin the mat in a shower. The connection between the power lead and the heating
wire must be fully embedded in mortar and located at least 1' (304.8 mm) away from shower
openings and other areas normally exposed to water.
9. Mat controls must be located at least 4' away from shower openings. Controls cannot be
exposed to water or touched by a person while in the shower area.
10. If covering a bench seat in the shower, carefully trim away mesh to release some heating
wire. Use hot glue to secure a single run of wire up the side of the bench riser. Fill in the
seat with mat. Then secure a single run of wire down the riser if needed. Use an "s-shaped
curve to avoid sharp bends at corners and help the wire to lay flat.
11. All grout seams should be sealed after the mortar and grout has completely cured.
Take photographs of the mat installation. This can be very useful later during remodel
work to help avoid possible wire damage. Keep the photos with this installation manual
and provide to end user upon completion.
