STEP 3.10:
Shower Application
Locate power lead and factory connection to heating wire at least 1' outside the shower area.
Acceptance of this application must be verified by the local inspector or authority having
jurisdiction (AHJ).
Tile
Thin-set
Mortar
1. Refer to diagrams in the Appendix, especially page 24.
2. Never install floor heating Mats in shower walls (or any other wall).
3. Never make a field splice to mats installed in a shower.
4. 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.
5. It is recommended that a dedicated mat be installed in the shower area, separate from
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.
6. Use the double-sided tape or hot-glue to secure the mat. Do not use staples or anything
that will damage any waterproofing membrane.
7. 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.
8. Embed mats in mortar and install only under tile, stone, brick, or other masonry surface,
per this instruction manual.
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. If the heating wire cannot exit the shower area, the end of the wire has a waterproof splice
that may be located in the shower area, fully embedded into the mortar like the heating wire.
