How To Install

Step 1:
Plan the layout and determine cable direction. Measure
about 3" in. inches from the wall, and place strap parallel to
the wall. Under toe kick spaces, install the strap 1.5"in. inches
to 2" in. inches away from the vanity.

Step 2:
Cut the strap to length for each side of area
to be heated.

Step 3:
Secure the strap to the subfloor using double-sided
tape, glue, or fasteners.

Step 4:
Fill in each section back and forth with cable,
spacing the wire 2.5" or 3" in. inches
apart. For additional areas, cut and attach the
straps accordingly and begin weaving the
wire into that area.

If cables are running greater than 3′ or 4’ft. feet across a room, be sure to add another
strap to thread through in the center of the area to be heated.
