Bench seat
If covering a bench seat or step area (not in a shower area), place a single run of cable up
the riser. Use a section of HeatMatrix to secure the cable to the seat at the desired spacing,
then install a single run down the riser. Use an "s-shaped" curve to avoid sharp bends in
the cable at corners and help the cable to lay flat. The cable MUST be fully embedded in
mortar and have approved floor coverings. Use hot glue where necessary to secure the
cable flat against the riser.
NEVER space the cables less than 2" apart at any point, and never less than 2.5" average.
Never space more than 3.5" average.
