Electric Floor
Warming Cable for Uncoupling Membrane for oor warming. This
product has been designed to gently warm ooring materials such
as marble, ceramic, glass and porcelain tile; slate; granite and
poured or dimensional stone, in addition to laminate and engineered
hardwood products. Warm Tiles greatly enhances the comfort level of
these beautiful ooring materials. The Electric Floor Warming Cable
is designed to be installed in oors in conjunction with uncoupling
membranes. The Electric Floor Warming Cable may usually be installed
in steps leading to baths, shower, etc. – check with Electrical Inspector
prior to installation.
Warm Tiles oor warming systems utilize state-of-the-art heating
cables, hardware and electrical controls for an economical and long
lasting oor warming system. Warm Tiles systems are designed for use
inside residential and commercial buildings of standard North American
construction.
Electric Floor Warming Cables are not designed as a primary source of
space heating for any room in which it is installed.
SKILL LEVEL
It is recommended that Warm Tiles systems be installed by professional
electricians, or by skilled “Do-It-Yourselfers” who have adequate
knowledge of ooring and electrical wiring, and in accordance with
all applicable national and local electrical and building codes and
ordinances, regulations and inspection procedures. Electrical inspection
may be required during and/or after system installation. Consult with
your local electrical inspection authority before beginning installation.
Keep this booklet for future reference, and pass on to any future users
of the system.
TILE FLOORING CONSIDERATIONS
For optimum performance, the top of the heating cables should be a
maximum of 3/4” (19 mm) below the nished oor surface. Cables can
also be installed in steps, including risers, leading to a bath/shower area
in most jurisdictions, but the cables must remain completely embedded
in mortar; check with your local electrical inspector before installing in
steps.
Cables can be installed in tiled showers or other wet areas, although it
is recommended that you check with your local electrical inspector rst
to verify that this application is allowed in your jurisdiction. Waterproof
membranes are usually used in these areas and in other areas where
large water spills may occur. These membranes are typically composed
of a waterproof thin lm (max. 0.080” (2 mm) thick).
Electric Floor Warming Cables are also suitable for applications under
oating laminate and engineered wood oors that are glued or snapped
together. Warm Tiles may not be used with any type of “nail down”
ooring, as the nails will damage the cable. WarmTiles cables may not
be installed under natural wood oors because the heat from the cables
will cause these oors to warp, crack and/or discolor. Before beginning
installation, check with the ooring manufacturer to verify that their
materials are suitable for electric radiant underoor heating.
WARNING
Electric Shock/Fire Hazard
Read the following warnings and instructions provided before
attempting installation. Failure to do so could result in cable failure,
improper system operation, property damage, bodily injury or death.
Failure to follow the warnings and instructions will also void the
warranty.
Use only uncoupling membranes that are recommended by the
membrane manufacturer for having heating cable installed within
them. If you are unsure about the membrane’s rated temperature
or ability to accommodate heating cable, please consult with the
membrane’s manufacturer. Electric Floor Warming Cables can be
installed in conjunction with only uncoupling membranes that have
been designed to be installed with some type of mortar or cement
under and over the membrane.
Electrical inspection may be required before, during and/or after
installation of the Warm Tiles system. Contact our local electrical
inspection authority for more information BEFORE BEGINNING
INSTALLATION.
Do not energize coiled heating cable – the cable will overheat.
Heating Cable must not touch, cross or overlap itself at any point
and cable must not be closer than 1½” (38mm) to adjacent cable.
This could cause the cable to overheat.
Do not install heating cable under any type of nailed-down or
stapled ooring. Floor nails and staples can damage the cable
resulting in exposed live electrical parts and/or result in the cable
overheating.
Do not drill or otherwise cut into oors that have Warm Tiles
cables – this could result in contact with live electrical parts or
could damage the cable causing it to overheat.
Do not use the Warm Tiles system for other types of applications,
such as snow melting or roof de-icing – the cable is not rated for
these types of applications. Contact EasyHeat for professional
advice for recommendations on other products for these
applications.
Do not alter the length of the heating cable to suit a oor area
larger or smaller than the recommended range for that cable. Only
the Cold Lead (black cable connected to the heating cable) may be
cut to suit hook-up in the Electrical Connection Box (ECB).
The entire Membrane, heating cable, the Cold Lead Splice and Tail
Splice must be embedded in a cement-based underlayment. The
heating cable could overheat if not entirely embedded in cement-
based underlayment. Never place any unused cable and in a wall
cavity – the cable will overheat.
Use caution when trowelling mortar/cement over heating cables –
trowels can become sharp and may cut heating cable which could
damage the ground braid, electrical insulation and/or expose live
heating element.
Cables must be at least 0.25” (6.5mm) below oor surface; if
cables are exposed, they could be damaged which would expose
live parts (shock hazard) and/or cause the cable to overheat
(re hazard).
