Cable Installation - Flextherm GreenCableSurface Guide D'installation

Conduit
(For all the details, refer to your local electrical code.)
A conduit approved for electrical wiring, inside which the non-heating
portion of the cable (cold lead) will be inserted, must be installed between
the electrical box and the floor.
• Unless approved for this application, electrical metallic conduits are not
allowed in wet environments (ex.: shower).
• PVC conduits are allowed only in walls that do not contain thermal insulation.
• The ends of the conduit must be deburred and bushings must be installed
to protect the cable against any mechanical damage.
• Conduits must be adequately secured.
Fish cord
Before installing the gyproc, install a temporary fish cord in the wall, between
the floor and the electrical box. When installing the probe on the floor, use
this cord to pull the probe wire to the thermostat. The probe wire must be run
outside the conduit containing the cold lead, outside the electrical box and be
inserted in the opening provided for this purpose on the thermostat's base.
IMPORTANT: Connect the cable to the thermostat only once
the cable has been installed and covered.
Note: Keep ends of the cold lead dry before and during installation.
Cold Lead
The cold lead is flat and black black, is 3 m (10 ft) long and is connected
to the heating cable with a mechanical joint. Just like the heating cable,
the mechanical joint must be installed on the floor and covered with the
selected mortar or self-levelling underlayment. Since the joint's diameter is
bigger than the heating cable's, it will be inserted in a groove in the sub-floor
in order to avoid unevenness when the floor covering will be installed.
Determine and mark the location where the mechanical joint will be
fastened to the sub-floor. With the appropriate tools, make a 6 mm (1/4 in)
groove on the sub-floor. Remove all debris caused by this operation to avoid
potential damages to the cable. Glue or screw the cable's mechanical joint
into the groove (picture 4). In a multiple cable installation, repeat these steps
for each cable installed.

Cable Installation

IMPORTANT!
Installation guidelines prior to installation, take note that...
• The cable will be installed at a minimum distance of:
- 5 cm (2 in) from the base (toe-kick) of a fixed furniture or
cabinet, toilet, patio door, bath or shower step;
- 5 cm (2 in) from any walls;
- 15 cm (6 in) from toilet drains;
- 20 cm (8 in) from any other heating system, floor or wall
mounted (this does not apply to a convection type of
heating appliance)
Green Cable Surface Installation Guide
Installation Plan
Above all, plan your installation while taking into account the above
mentioned guidelines. It is recommended to make an installation plan in
order to foresee direction changes, obstacle skirting, buffer zones, etc. Buffer
zones are areas that are not essential to heat (i.e. behind the toilet, behind a
door, or any other low traffic area) that can accommodate any excess cable.
Using a suitable marker, draw the obstacles to be bypassed directly onto the
sub-floor (picture 5).
Plan the installation to fit the entire cable in the room: the heating cable shall
not extend beyond the room or area in which it originates.
The FLEXTHERM Green Cable Surface displays the length of the cable at each
foot, which facilitates the system's installation. By knowing the amount of feet
left to install, it is easy to determine the path of the cable.
Picture 4
Ensure that the buffer zones are easily accessible to accommodate any excess
cable while abiding by all the installation instructions. If multiple cables
are required for the installation, each run of the cable should be carefully
planned to ensure that the spacing between the cables is always met.
• The cable must be spaced at least 13 mm (1/2 in) from any
exposed combustible surface.
• The cable cannot be overlapped, crossed, cut, shortened nor
modified.
• The spacing between the cable runs must remain unchanged
throughout the installation.
• Cables must be installed in runs lesser than 3 m (10 ft).
Divide the room in smaller sections, should your room
exceed 3 m (10 ft).
• FLEXTHERM Universal Snap-in Gauges™ or the FLEXSnap
installation system are the only approved anchoring devices.
The use of any other anchoring method (e.g. staples or nails)
will immediately void the warranty.
• All the heating portion of the cable (including the
mechanical joint) must be secured to the floor and covered
with mortar or self-levelling underlayment. The heating
cable should never be, under any consideration, installed in/
on walls.
• The system should not be installed under fixed furniture or
where air does not flow freely. It should never be installed in
closets, over walls or partitions nor over cabinets.
• The heating cable should never be installed over an
expansion joint.
• The installation of the system should not be performed
under 0 °C (32 °F) ambient air temperature.
