FLOOR TRANSITION
To install the heating cable between two horizontal oors please
follow the following important notes:
• The heating section of the cable must not pass through a wall
and/or be installed inside a structure.
• The minimum radius of curvature of the cable is 0.5 in. (13mm).
• The height of the oor transition does not matter as long as the
vertical surface of the transition is covered with ceramic
• Carve out small transition channels (between horizontal
and vertical transitions and vice versa) and round off any
sharp corners. Make sure the entry angle of the cable is not
perpendicular to the wall (see picture). This will allow for a
greater radius in the heating cable.
THERMOSTAT SELECTION
WIRING
Only a thermostat equipped with a oor sensor maximizes the oor heating system’s efciency and, therefore, your comfort. All other control methods (e.g.
ambient air thermostat or switch) are not recommended since they cannot control the oor temperature. As a result, the oor temperature will always be either
too cold or too warm.
Also, the heating cable must be connected to a ground-fault GFCI circuit interrupter either integrated in the thermostat, or panel mounted. For a bathroom, the
GFCI circuit must be class A (5 mA).
The maximum thermostat current must correspond to the sum of cable currents wired to it. Also, the voltage of the branch circuit must correspond to the voltage
prescribed for the thermostat. All thermostats wired to the heating cable must be certied by a recognized certication agency and wired in accordance with
electrical and building codes applicable in your region.
Initial start up of the oor heating system must be delayed until the end of the curing period (typically 28 days). Otherwise, the concrete adhesive properties
will be compromised, thus reducing the oor covering adhesion. Contact a oor covering specialist to ensure proper adhesion.
PREPARATION BEFORE THE CONNECTION
Make sure that the circuit is not energized.
The CSA identication tag of the heating cable must be in the junction box. Do not remove it from the cable.
The wiring of the cable to the thermostat or the relay, must be completed accordingly with the thermostat/relay manufacturer’s recommendations.
Connect the ground wire (copper braided wire) to the junction box.
The oor heating system must be connected to a ground-fault circuit interrupter “GFCI” either integrated in the thermostat, or panel mounted.
Place the warning label below on the electric panel board to mark the branch circuit supplying the oor heating cable.
