may result and may cause dangerous problems. Extra forethought at this
stage will make the rest of the installation much easier.
General Installation
STEP 5.5 Measure about 3” from the wall for the strap. If the design called
for 6”–12” away from the wall, install the strap at that distance. In counter
or vanity kick-spaces, install the strap so the cable will be 1-1/2” to 2” away
from the vanity.
STEP 5.6 Cut the strap to fit the length of the first area.
STEP 5.7 Secure the strap to the floor using double-sided tape (if factory
supplied with your cables), or using a
strong spray adhesive (such as 3M™
Hi-Strength 90 or similar), spray an
even coat onto the backside of the
strap and the area of floor where it
will be placed, allow the adhesive to
get tacky (per product instructions),
then turn the strap over and firmly
press onto the floor. Follow all manu-
facturer‘s instructions when using a
spray adhesive.
STEP 5.8 For floor surfaces other
than concrete, secure the strap to the
floor using galvanized nails or screws.
Secure the strap every 6”–10”.
STEP 5.9 For added securement, on
concrete floors, use a hammer drill to
set holes into the concrete. Secure the
strap every 6”–10” by driving anchors
into the holes.
STEP 5.10 Cut another piece of
strap for the other end of the area
and secure 3” from the wall(s) or other
obstruction(s).
STEP 5.11 Unreel the p ower leads
of the cable up to the factory splice.
Let the coil of power leads sit on
the floor for now. Beyond the fac-
tory splice is the heating cable itself.
Factory splice must be installed
in the mortar bed. CAUTION:
Completely embed the factory
splices and heating cable in the
mortar, and never bend the factory
splices. NEVER allow any part of the
splice or heating cable to enter a
wall or drop through the subfloor.
STEP 5.12 Before installing more
strap, fill in the first section with
cable. Begin by making a “strain-
relief” at the beginning so the cable
is not accidentally pulled loose.
Zigzag the cable under the tabs only
as shown. Press the tabs down to
secure the cable.
STEP 5.13 Weave the cable back
and forth across the area at the
desired spacing until the other side
of the room has been reached. Once
this area is completed, press down all
the tabs. NEVER space the cables less
than 2” apart.
STEP 5.14 If there are additional
areas to cover with cable, cut the
lengths of strap necessary, attach
them to the floor, and begin weaving
the cable into that area.
