Phase 6: Finish Wiring
STEP 6.1 Chisel a channel into the floor to lay the factory splice into. This
will ensure the splice does not create a high-spot in the floor. CAUTION:
The power lead splice MUST BE FULLY EMBEDDED IN the mortar bed 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.
New Construction
STEP 6.2 Feed the power leads from the cable up through the hole drilled
in the baseplate, or up into the conduit to the control electrical b ox
(or junction box if one was used).
STEP 6.3 Secure the power lead splice into the chiseled channels with
hot-glue.
STEP 6.4 Below the control, or wherever the floor sensor is to be located,
measure at least 1 ft. into the heated area. Mark the spot where the sensor
will be attached to the floor. Be sure to locate the sensor exactly between
two of the heating cables.
STEP 6.5 To make sure the sensor tip does not create a high spot in the
floor, chisel a channel into the floor and lay the sensor tip into the channel.
Hot glue the tip into place.
STEP 6.6 Drill another hole into
the baseplate, if needed, to feed
the sensor wire up to the control
box. Finish by securing a steel nail
plate over the wires to protect them
against baseboard nails later.
STEP 6.7 If it was necessary to end
a power lead at a junction box, feed
14- or 12-gauge electrical wire from
this box to the control box.
Tip: If more than one cable was
installed, label the ends of the power
leads with a brief description as to
which area they supply power. Use
tape to label them “Cable 1,” “Cable
2,” “Kitchen,” “Bath,” or similar. This
will mak e it easier to identify the
leads later on. Take photos of the
installation. This will provide a use-
ful record for any future needs.
Existing Construction
STEP 6.8 Use a fish tape to pull the
power leads up the wall to the con-
trol electrical box (or junction box if
one was used).
STEP 6.9 Secure the power lead
factory splice into the chisled chan-
nel with hot-glue (see photo for Step
6.3).
STEP 6.10 Below the control, or
wherever the floor sensor is to be
located, measure at least 1 ft. into the
heated area. Mark the spot where the
sensor will be attached to the floor.
Be sure to locate the sensor exactly
between two of the heating cables (see photo Step 6.4). To make sure the sen-
sor tip does not create a high spot in the floor, chisel a channel into the floor
and lay the sensor tip into the channel. Hot glue the tip into place (see photo
Step 6.5).
STEP 6.11 Use a fish tape to pull the sensor up the wall to the control electri-
cal box, and finish by securing a steel nail plate over the power leads and sen-
sor wires to protect them against baseboard nails.
