BEFORE YOU BEGIN

Product Information

The STRATA_HEAT Wire consists of:

A twin conductor resistance heating cable with a primary insulation of Fluoropolymer with high dielectric strength and high temperature

properties. The conductors are covered by a ground braid providing additional mechanical strength and a ground path. A final outer jacket

of PVC is given to make it sturdier and provide corrosion protection.

The heating cable is terminated at one end with a 10' (3.1 m) cold lead. The conductor cores and ground braid are factory joined in a

water resistant joint assembly to each supply conductor and ground conductor of the unheated lead. The heater is terminated at the other

end with a smaller water resistant joint.

The unheated power connection lead (10 ft / 3.1 m) can be trimmed to your needs or extended using a suitable UL-approved wire.

Always complete cable connections in a junction box. Do not leave excess wire in the wall. This must be carried out by a qualified

electrician in accordance with local/state laws and guidelines. Inspect the entire heating cable for damage, this includes the factory made

joint and end termination. If any parts are damaged contact LATICRETE Customer Service.

If you are missing any items from the box or believe that you have the incorrect STRATA_HEAT Wire to cover the area required, please call

the helpline for further assistance.

Note: The STRATA_HEAT™Wire spacing must be no less than 3" (76 mm) at all times. The maximum area loading MUST NOT exceed

15W/sq ft. (15 W/929 cm2)

The table below can be taken as a general guide. Actual requirements will depend on the floor construction, type of floor coverings,

insulation levels etc. The STRATA_HEAT™ Wire selection will depend on the application.

Application W/sq ft

New floors in builds with high levels of insulation 13W/sq ft (13W/929 cm2)

Wooden floors 11W/sq ft (13W/929 cm2)

Wet areas (showers, bathrooms, steam rooms etc) 13W/sq ft (13W/929 cm2)

Note: The UL Listing for this product covers use in wet locations for CANADA only. Wet location installation in United States shall be

in accordance with the National Electric Code, NFPA 70 and any other applicable jurisdictional code and final acceptance is to be made by

the Authority having Jurisdiction (AHJ).

Thermal Insulation

The insulation levels of a floor will affect both the performance & running costs of under tile heating. Using the heating cable without

thermal insulation can take up to 5 hours to heat a room whereas a system with thermal insulation takes less than an hour.

If the LATICRETE STRATA_HEAT Wire is being installed onto a concrete base it is highly recommended that a layer of insulation is used

prior to installing the heating cable. The thermal insulation reflects the heat upwards instead of allowing heat to penetrate into the

subfloor, greatly improving the warm-up times & running costs.

The thickness of insulation required will depend on whether it is for floor renovation or a new floor.

Floor Coverings

All floor finishes should be installed as per the manufacturer´s instructions. With radiant heating, the floor covering is essentially part of

the heating system. The most suitable floor coverings are those with a low thermal resistance, normally referred to as the R-value.

The type and thickness of floor covering materials used with this product must not exceed a thermal insulation “R” value of 1.

Floor covering R Value

Carpet 1.0

Ceramic, Mosaic Tile 0.15

Laminate Flooring 0.675

Natural Stone 0.38 - 0.114

Wood Flooring 0.80

STRATA_HEAT™WIRE HEATING CABLE SELECTION

Ensure that the subfloor is smooth, dry and free from dust. Visually check that there are no objects on the floor that might damage the

heater.

Where necessary an appropriate smoothing compound should be applied and allowed to cure.

If the cable is being fitted to a solid floor it is essential that the concrete slab has been allowed to cure.

If using the HYDRO BAN®Boards, use a suitable cement based adhesive and screws to the subfloor as per the instructions.

If installing in a wet room ensure a slope in the mortar bed is maintained in order to direct water to the drain pipe.

SUBFLOOR PREPARATION

LATICRETE only recommends STRATA_HEAT™ Thermostats designed for use with underfloor heating to control the STRATA_HEAT Wire

loose heating cables. When using multiple loose heating cables you can connect them in parallel to the same thermostat. Check with your

installer or call LATICRETE for circuit sizes and maximum loads.

The thermostats come with a 9' (2.74 m) sensor cable to detect the temperature under the floor finish. The end of the probe wire

contains a capped sensor that should be evenly centered between two heating cables at least 12" (305 mm) into the heated area. At no

time should the probe wire cross the heating cable.

If you have more than one heating cable, all the lead wires need to be connected in parallel to the thermostat. For convenience, it may

be easier to run multiple lead wires to a junction box and then take a single wire (which has the appropriate rating) from the junction box

to the thermostat.

NOTE: 240V wires are Red and Black. 120V wires are Yellow and Black. Connect ground wires to the power source ground.

The total Amp load of the heating cable(s) must not exceed the thermostat’s Amp limit or the Amperage rating of the circuit or other

control switch without using an appropriately rated contactor/relay.

The LATICRETE STRATA_HEAT Wire has a maximum resistive load of 15 Amps. Please refer to the table on page 7 to calculate the

amperage load for your particular system.

For smaller areas, you may be able to utilize an existing circuit. In most cases, however, you will need a separate dedicated circuit to

power the LATICRETE STRATA_HEAT Wire heating cables.

The STRATA_HEAT Thermostat should be connected to the main electrical supply via a fuse or circuit in accordance with the National

Electrical Code. If the STRATA_HEAT Thermostat used does not include a built-in Ground Fault Circuit Interrupter (GFCI), then one must be

added to the circuit between the main power supply and the thermostat. If the thermostat does include a GFCI, it is NOT recommended to

include another in the circuit, as this may cause accidental tripping of the control unit.

Further details on the installation of the thermostat can be found in the instruction manual included with the thermostat.

Ensuring Safety

Install the STRATA_HEAT Thermostat within the same room as the STRATA_HEAT Wire heating cables. In order to ensure the efficient

running of the system within bathrooms, we recommend that the controls are located at least 60 inches (1.52 m) away from shower

openings or basin back splash areas so you minimize the possibility of exposure to water.

The control card on page 23 of this manual must be attached to the circuit breaker box for referral by the homeowner or electrical

inspector.
