YOUR SAFETY IS IMPORTANT TO US
This guide contains instructions regarding safety as well as precautions to take to ensure a compliant and successful
installation. Please pay special attention to this symbol and follow any instruction given.
Congratulations, you are now a FLEXTHERM customer. For the best possible
installation, please read the following guide before you begin. Ensure that
the installation is in accordance with the current construction standards in
your region.
This product was designed to be installed under ceramic and natural
stone floor coverings only. The Green Cable Mat is made of a self-
adhesive mesh on which a heating cable of 3W per linear foot, at a
regular spacing of 7.6 cm (3 in), is fixed. This product is recommended
for installation in square or rectangular shaped rooms. For rooms of irregular
shape, we recommend our Green Cable Surface to obtain better results. More
information can be found by visiting us online at www.flextherm.com or by
contacting us by phone at 1-800-353-9843.
The FLEXTHERM Green Cable Mat can be used as a main source of heating
(provided the heat loss of the room does not exceed the energy capacity of
the installation) or as an added touch of comfort at your feet. The maximum
ambient and floor temperature that can be attained is dependent on the
insulation of the room, window coverage, type of floor covering used, etc.
To learn more about the performance that can be attained by the system in
your particular installation, refer to the construction professional (architect,
engineer) that manages your project.
This system is designed and approved for indoor heating in wet or dry
environments, subject to local electrical standards.
For any additional information, please consult your authorized FLEXTHERM
dealer.

TYPE C USA
This mat is an electrical appliance and should be installed according the
local and/or national electrical codes. Its installation should be entrusted to a
qualified electrical professional where required by law.
Required materials and tools for installation
In order to install the system, you will need the following items:
1. FLEXTHERM Green Cable Mat kit, including: mat and installation guide.
2. FLEXTHERM thermostat and floor probe, sold separately.
3. Expanded electrical connection box.
4. Protective plate for the wall sill plate.
5. Appropriate multimeter.
6. Megohmmeter.
7. Various tools: measuring tape, calculator, marker, screw driver, tools to
groove the sub-floor, fish cords (to raise the cables in the wall), scissors for
the mesh and electrical tape.
8. Vacuum cleaner, broom, pail of water and sponge.
9. Cardboard or other light material (to put the tools on).
Though the mesh is self-adhesive, if required you may solidify its installation
with the help of staples or hot glue.
WARNING: Under no circumstance should the heating cable integrated in
the mesh be damaged, pierced or held in place through the use of staples;
the functionality of the floor heating system will be compromised. Only the
mesh can be stapled.

Floor surface preparation
General instructions
IMPORTANT: The sub-floor must respect the established
construction standards to ensure that it is stable enough to
support ceramic tile, natural stone or self-levelling
underlayment. Refer to Tile Council of North America
publications for installation standards (www.tileusa.com).
Always check with the sub-floor material manufacturer to ensure
compatibility with floor heating systems. Whatever the selected sub-floor,
the floor surface must be clean, flat, smooth, and free of protruding nail or
screw heads or other materials that may damage the cable integrated in the
mesh. Always ensure that the selected sub-floor is compatible with mortars
or self-levelling underlayments.
Compatible sub-fl oors
Plywood and Cement Board
FLEXTHERM floor warming and heating systems are installed directly on a
plywood surface and cement board without any specifi c fl oor preparation,
other than the general instructions mentioned above.
Smooth Concrete Slab
The concrete slab must be insulated to avoid energy loss due to the effects
of variable elements on a thermal mass. When a concrete slab is chosen as
the sub-floor and to avoid heat loss on the perimeter, we recommend that
all the rooms the slab supports be heated with a FLEXTHERM floor warming
and heating system. If these conditions cannot be met, you will need to
install an appropriate insulating barrier between the slab and the floor
heating system to avoid heat loss.
Ceramic
Refer to the mortar or self-levelling underlayment manufacturer to
adequately prepare the sub-floor to ensure proper adhesion.
Acoustic Membrane
Install the membrane following the manufacturer recommendations. The
heating mat is to be installed on top of the membrane which must be
properly glued to the sub-floor prior to installing the mat.
Anti-fracture Membrane
The heating mat is generally installed on top of the membrane. However,
certain manufacturers recommend that the mat be installed under the
membrane. Always check with the manufacturer prior to proceeding with
the installation.
Mortar Bed (Sand Coat)
The Green Cable Mat and the floor probe must be installed on top of the
mortar bed. To ensure the adhesion of the mat, the mortar bed must be
smoothed with a flat trowel in order to obtain a surface that is smooth and
uniform, not granular. If the surface is too granular, glaze the mortar bed with
mortar.
Scratch Coat
To avoid any risk of damage, always glaze the mesh to obtain a smooth
surface, prior to installing the heating mat.
