Planning The Installation; Subfloor Specifications - LATICRETE Floor HEAT Manual De Instalación

This instruction manual shall be made in accordance with Article 424, part IX of the National Electric Code ANSI/NFPA 70.

PlAnning ThE inSTAllATiOn

Before laying the LATICRETE Floor HEAT mat, review the installation layout
and verify that all dimensions match the field dimensions. Details for
floor layouts can be obtained from LATICRETE at www.laticrete.com/fw.
The installation plan should include the following:
1. Placement, direction, and dimensions of the LATICRETE Floor HEAT mat
2. The starting and ending points of each mat
3. The location of the LATICRETE Floor Warming Thermostat or other
suitable control
4. The location of the floor sensor

SuBFlOOR SPECiFiCATiOnS

LATICRETE Floor HEAT should be installed directly over substrates such as
concrete slabs, backer boards and self-leveling underlayment in accordance
with all Tile Council of North America guidelines. All materials in direct contact
with the heating element MUST be rated to withstand 180°F (82°C).
LATICRETE Floor HEAT will be most effective and efficient if installed over
well-insulated areas. Insulation will minimize heat loss into the subfloor

DOn'T
DON'T shorten the heating mat.
DON'T cut the heating wire.
DON'T drop or bang any tools (i.e. trowel) on or hit the heating wires
with any sharp objects.
DON'T install any fasteners such as nails, screws, etc. through any area
covered by the LATICRETE Floor HEAT mat.
DON'T install LATICRETE Floor HEAT mat under cabinets, built-in
appliances, etc. to avoid excessive heat from building up in those areas.
DON'T install LATICRETE Floor HEAT mats over expansion joints.
DON'T install LATICRETE Floor HEAT mats in walls.
DON'T install LATICRETE Floor HEAT mats in showers.
DON'T overlap LATICRETE Floor HEAT mats or allow any wires to cross or
touch each other.
DON'T crimp the heating wire while customizing the LATICRETE Floor HEAT mat.
DON'T place area or throw rugs over the heated area to avoid excessive
build-up of heat in these areas.
DON'T attempt to repair the heating wire without the proper instructions
and repair kit (obtained from your distributor or LATICRETE International).
DON'T forget to install the floor-sensor if you are installing a
LATICRETE Floor Warming Thermostat or any other thermostat.
DON'T install directly below vinyl, carpet or wood flooring.
(i.e. concrete slab), allowing the heat to transfer to the surface more quickly.
LATICRETE Floor HEAT is designed exclusively for installation under
ceramic tile, marble, and other stone floorings. There are limitations in
applications that utilize different floor coverings. Please consult with the
LATICRETE Technical Services Department for details on heating other types
of floor covering.
never install lATiCRETE Floor hEAT directly below vinyl,
carpet or wood flooring. lATiCRETE Floor hEAT must be
embedded in mortar.
The type and thickness of the applicable floor coverings
must not exceed a thermal resistance value (R Value) of
1.0 ft °Fh/Btu.

WARning: Risk of electric shock and fire. Damage to supply conductor
insulation may occur if conductors are routed less than 2" (51 mm) from this
heating product. Refer to installation Instructions for recommended means of
routing supply conductors.
DO
Clean the floor of all debris before placing the LATICRETE
on the floor. Wipe the substrate with a sponge that is clean and damp.
Make sure there are no protruding objects (nails, staples, etc.) on the
subfloor that could damage the heating element.
Walk over the unprotected mat with rubber soled shoes.
Measure and record LATICRETE Floor HEAT mat resistance as per
instructions.
Use mats that have the same heat output. ALL mats should be either 10
watts per square foot (300 mm ) or 15 watts per square foot (300 mm
