Installation Guide
WARNING:
PRECAUTIONS TO TAKE WHILE INSTALLING THE
FLOORING
When mortar is used, never hit the trowel on the heating cable
to remove excess mortar from the trowel: the cables could
be damaged. Use a sponge or a wet cloth to remove excess
cement as you install the tile: do not use a utility knife or the
edge of your trowel. These tools could damage the heating
cable. During all operations, lay tools and materials (buckets,
etc.) on a piece of cardboard instead of directly on the cables.
Note regarding the floor stability
Floor stability will vary according to the type of flooring installed and its
components. Mortar manufacturers and the Tile Council of North America
(TCNA) strongly recommend the use of expansion joints on the perimeter
of the room and obstacles as well as across the room (reference TCNA article
EJ-171).
Should you require more information regarding tile installation or sub-floor
construction, contact the TCNA (www.tileusa.com).
Mat verification
Once floor covering installation is complete, verify the mat’s integrity one
more time, as described in the “Mat Verification” section at the beginning of
this guide. Record the results on the warranty card.
Connection to the thermostat
DANGER: SEVERE RISK OF ELECTROCUTION
Turn off the power of the designated electrical circuit prior to
connecting the system controls.
Compatible thermostats
Use FLEXTHERM thermostats to operate the system. These thermostats
are equipped with a class A ground fault circuit interrupter (GFCI) that will
protect the system in case of fault. To preserve the system’s warranty the use
of a thermostat equipped with a class A GFCI (5 mA) is required.
Single-circuit installations
Connect the system’s green wire (ground) to the terminal in the connection
box. Proceed as per the instructions in the FLEXTHERM electronic thermostat
installation manual. Identify the circuit on the electrical panel.
Multiple-circuit installations
Should your installation require more than one circuit, you will need one
thermostat, one master/expansion conversion kit, and the appropriate
number of expansion units, as indicated in the “Preliminary Electrical
Installation” section. For their connection, refer to the instruction guide
provided with the FLEXTHERM thermostat and the FLEXTHERM master/
expansion conversion kit. Identify the circuits on the electrical panel.
Keep installation and user guides
Please keep the thermostat instructions in a safe place for future reference.
System start-up
Curing period
Do not turn your system on immediately. The system can be operated
only after the mortar or self-levelling underlayment has completely cured.
This waiting period is essential to ensure that the mortar or self-levelling
underlayment is properly set. Refer to your manufacturer’s instructions to
verify the curing time for the product you are using (generally 28 days).
Use of rugs
Do not lay a rug on a floor equipped with a heating system. The heat that
would get trapped could alter your rug or your flooring. The use of a bath
mat is acceptable, as long as it is removed from the floor once the bath
period is over. For the same reason, furniture under which air cannot freely
circulate should not be placed on flooring under which there is a floor
heating system.
Repair
Should the flooring need repair, proceed with caution. Always turn off the
power supply and remove the piece of flooring that needs to be repaired. In
the case of ceramic or natural stone floors, gently scrape the grout around
the tile to be replaced to a maximum depth of 3 mm (1/8 in), and break
the tile with a hammer starting from the center (do not use excessive force
which could damage the cable). Without damaging the cable, carefully
remove the mortar with a chisel or a scraper.
Should the cable be damaged in the process and/or the GFCI be set off,
the system is out of service and should not be activated. THE CABLE CAN
BE REPAIRED. A repair kit (product code: FSK-03) is available from your
FLEXTHERM dealer.
Never attempt to repair a cable located in a wet area. Contact FLEXTHERM
customer service at 1-800-353-9843.
FLEXTHERM’s Floor Warming and Heating System is maintenance free.
Should it stop heating, immediately contact FLEXTHERM customer service at
1-800- 353-9843.
