Flextherm Green cable mat Guide D'installation page 4

Note: the floor probe is included in the thermostat kit.
IMPORTANT: Connect the cable to the thermostat only once
the cable has been installed and covered.
Note: Keep ends of heating devices and kit components dry before and
during installation.
Cold lead
The cold lead is the non-heating portion of the heating cable. It is fished/
run through the wall and is used to make the connection to the thermostat.
You will recognize the cold lead as it is a flat black cable connected to the
heating cable (green) through the mechanical joint (picture 5).
Mechanical joint
Cold lead
Just like the heating cable (integrated in the mat), the mechanical joint must
be installed/secured to the floor and covered with the selected mortar or
self-levelling underlayment. Since the joint's diameter is greater than that
of the mat, it will be inserted into a groove in the sub-floor in order to avoid
unevenness when the floor covering is 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 in the sub-floor. Remove all debris caused by this operation to avoid
potential damage to the cable. Glue or screw the cable's mechanical joint
into the groove (picture 6). In a multiple mat installation, repeat these steps
for each mat installed.

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 directional 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 mat.
Using a marker, draw the obstacles to be bypassed directly onto the sub-
floor. Plan the installation to fit the entire mat in the room. The heating mat
should not extend beyond the room or area in which it originates. Plan
on ending your installation in a buffer zone to use any excess mat, while
respecting the installation guidelines.
If multiple mats are required for the installation, each run of the mat should
be carefully planned to ensure that the installation guidelines are always
met.
It is possible the mat will not cover the entire surface area of the room. You
can add a 3W Green Cable Surface and gauges to your installation, making
sure you use the same 3 in spacing as the mat.
Note: Under no circumstance should the Green Cable Surface be installed
over the mat.

IMPORTANT! INSTALLATION GUIDELINES
• The heating part of the mat will be installed at a minimum
distance of:
- 13 to 25 mm (1/2 to 1 in) from the base (underside) of
a counter, fixed furniture, steps, patio doors, baths or
showers;
- 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 convection type heating
appliance).
• The cable must be spaced at least 13 mm (1/2 in) from any
exposed combustible surface.
• The heating cable integrated in the mesh (mat) should at no
time be overlapped, crossed, cut, shortened nor modified.
• The spacing between the runs of mat must remain
unchanged throughout the installation.
• The entire heating portion of the mat (including the
mechanical joint) must be secured to the floor and covered
with mortar or self-levelling underlayment. The heating mat
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 mat should never be installed over an expansion
joint.
• The installation of the system should not be performed in an
environment where ambient air temperature is under 0 °C
(32 °F).
