Congratulations
, you are now a FLEXTHERM
Floor Warming & Heating System
owner. To ensure 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 is designed to be installed at a regular spacing of 10 cm
(4 in) or 15 cm (6 in)
. Choose the mesh according to the designated cable
spacing. Installation at spacings other than those herein to mentioned can be
done upon recommendation by a professional only. Under no circumstances
can the spacing be modified during the installation. Refer to the “Cable
Installation” section of this guide to confirm the appropriate spacing for your
installation.
This product can be used as a main source of heating (provided the heat
loss of the room falls below the energy installation capabilities) or as an
added touch of comfort at your feet. The Green Cable
Concrete
is designed
to generate 161 W/m
2
(15 W/ft
2
) when installed at a 10 cm (4 in) spacing or
108 W/m
2
(10 W/ft
2
) when installed at a 15 cm (6 in) spacing. The ambient
and floor temperatures that can be achieved are dependent on the insulation
of the room and of the slab, window coverage, type of floor covering used,
etc. To learn more about the performance of the system for your particular
installation, refer to the construction professional (architect, engineer) that
manages your project.
This system is designed and approved for interior room heating in wet or dry
environments, subject to local electrical standards.
For any additional information, please consult your authorized FLEXTHERM
dealer.
HEATING CABLE, SERIES
TYPE G AND W CANADA, TYPE C USA
This cable is an electrical appliance and should be installed according to the
local and/or national electrical codes. Its installation should be entrusted to
duly qualified personnel where required by law.
Required Materials and Tools
In order to install the system, you will need the following items:
1. FLEXTHERM Floor Warming and Heating Cable kit including: heating
cable(s), FLEXTHERM adhesive tape and installation guide.
2. FLEXTHERM thermostat and floor probe, sold separately.*
3. Expanded electrical connection box.
4. Appropriate
multimeter.
5. Megohmmeter.
6. Mesh of caliber 6 or higher (square size corresponding to the selected
spacing: 4 in x 4 in or 6 in x 6 in).
7. Bricks or shims (to raise the mesh).
8. Styrofoam panel reinforced with plywood (for cable protection during
concrete pour).
9. Various tools: measuring tape; calculator; electrical tape; a 2.5 cm (1 in)
diameter and 30 cm (1 ft) long stick or pipe for the dispenser box; spray
paint or equivalent to mark wall location, permanent fixtures, etc on the
thermal insulation.
* Optional kit including a cable conduit and a probe specifically designed for
embedding in concrete is available (product no FLS1250).
Surface Preparation
The design, construction and power of the Green Cable
Concrete
make it a
product specifically engineered for embedding in a concrete slab.
Prepare the surface that will receive the reinforced concrete slab in
accordance with the local and national code in effect in your area. Mark
the limits of the area to be heated, the future partitions, walls, control or
expansion joints and any other obstacle that has to be skirted (main drain,
column, fixed furniture, etc.).
To minimize heat loss, lay an R-10 high density incompressible insulating
material over a bed of crushed stone, gravel or graded sand.
The cable is secured to the mesh used to reinforce the slab. The mesh
squares must be aligned and the sheets must overlap by a complete square.
Solidly secure the sheets to one another every 30 cm (1 ft). To maximize their
performance, cables should be placed at approximately 5 cm (2 in) from the
surface. Place the mesh on bricks or shims, spaced at a maximum of 60 cm
(24 in) from each other, so that it is level and reaches the designated height.
Room Measurements Verifi cation
IMPORTANT
: Accurate measurements are the key to a
successful installation. Verify your measurements in order to
ensure that you have the appropriate cable length for the
project.
Cable Verifi cation
The FLEXTHERM seal on the cable warrants the integrity of the cable. The
cable cannot be returned if the seal is broken. As a quality assurance measure,
each cable has been subjected to a 1,500 V dielectric test and resistance test.
Before removing the seal and installing the system, the cable insulation and
resistance should be verified to ensure the cable conformity. You will have
to verify the cable integrity two more times during the installation: once the
cable is secured to the mesh and once it is covered with concrete. These tests
are conducted three times to make certain that no damage was caused to
the cable during the different stages of the installation.
Resistance Verifi cation
Use an appropriate multimeter to measure the resistance between the black
leads. (

If an automatic multimeter is used the reading will be taken instantly. If the
multimeter is not automatic, set it to 200 Ω for a cable under 200 Ω or at
