Note: When a part of the product specication must be changed to improve operability or other functions, priority is given to the product specication itself. In such
instances, the instruction manual may not entirely match all the functions of the actual product. Therefore, the actual product and packaging, as well as the name
and illustration, may differ from the manual. Make sure that the connections have been made safely and securely. Failing to follow these instructions may cause a
re hazard.
THANK YOU FOR CHOOSING THE STELPRO FLOOR HEATING SYSTEM
This guide has been written to guide you during the installation of your
oor heating system. It has been prepared according to North American
construction standards. Because construction standards in your area may
vary, consult a certied electrician in your region before installing the oor
heating system.
The oor heating system is designed to heat a room with a heating cable
placed under your oor covering. It can heat oor covering materials such
as marble, ceramic and porcelain tiles, slate, granite as well as poured
surfaces. Before using the oor heating system under any other oor
covering, contact your oor covering manufacturer.
The oor heating system will heat your house regardless of the size or
shape of each room. This product is designed for INDOOR USE ONLY, in
residential, commercial and institutional buildings.
The oor heating system is available as “cable sets” of 120 volts
and 208 volts/240 volts (see the SELECTION TABLES on page 4).
Recommended heating capacity: 12 W/square foot (0.3 m²) or 9 W square
foot (0.3m²) when used as supplementary heating.
To ease the installation, Stelpro provides mounting brackets, hot glue sticks
and a temperature sensor with the heating cable. You will nd installation
instructions for these accessories further in this guide. It is important to
connect the sensor to the heating cable thermostat. Please note that you
must install the sensor before the mortar, even if you haven’t bought the
thermostat yet.
As a preventative measure it is recommended that you install
two sensors: the sensor provided with the thermostat and
the sensor provided with the cable. One sensor is connected
to the thermostat and the second is kept in the thermostat
junction box as a backup.
The heating section of the cable must never touch or cross over itself.
The minimum radius of curvature is 13 mm (1/2 inch).
This cable must be grounded and connected to a ground fault circuit interrupter (GFCI). The GFCI must be a class A (5 mA) for a bathroom in
Canada. In the U.S the GFCI must be a class A (5 mA) for a bathroom and kitchen.
If the installer or the user modies the unit, he will be held responsible for any damage resulting from this modication, and the warranty and the CSA
certication will be void.
Never energize the cable while it is on the spool. This would lead to overheating that could damage the cable and may cause a re.
The heating cable must not surpass the room or space where it will be used as a primary heating source (installed with a 3-inch spacing). The heating section of
the cable must not pass through or be installed in a wall.
Never use the heating cable for any purpose other than heating a oor INSIDE a building.
Always keep a minimum of 3 inches of space between cable runs. Failure to do so may result in a re or damage to the oor covering.
Never install a cable designed for a 120 V power source on a 240/208 V power source.
Avoid folding the heating cable on itself, this could damage its sheath and the internal wires.
WARNING
To avoid damaging the heating cable spool when removing it from the packaging, we
recommend to pick up the spool from underneath (A) or by the side (B) (by turning
the box over).
