With radiant heat, you get a cozy warmth rising from the floor heating your room uniformly all day long. There is no tubing, water or pumps as with the old systems. It’s a solid hardwood floating floor system that installs without screws, nails or glue. Instead, the boards clip together using a patented system. You’ll need five essential components to install this system: This coating forms a moisture-proof barrier and can be applied over new concrete in as little as five days. Homeowners can optimize comfort, reduce utility costs and view energy use statistics from anywhere. Set the room temperature using voice control through your home automation system. One thing you may notice is that they refer to tile as the flooring material. However, it’s perfectly acceptable to use with Easiklip solid hardwood floors.Laticrete recommends using NXT Level instead of a tile adhesive.

Also, you will use a flat edge of the trowel to smooth it rather than a notched edge for installing tile. For detailed information, download the manual here. Or, you can watch the overview video here. The basic setup is like this: For more info about GFCIs and installation, refer to page 9 of the installation manual. Install it as you would any underlayment. This insulating underlayment prevents too much heat from absorbing into the sub-floor. Screws or nails should not be used as these will puncture the moisture barrier. The kit includes spacing strips to keep the wire runs at least 3” (7.6 cm) from the wall. It will cause overheating and damage the wire. If you decide to install it in the bathroom, place the thermostat at least 60” (153 cm) from the sink and shower. When it’s dry, you’ll install the hardwood floor. The boards have a tongue and groove along each side. On one side there is an extra groove where the clip snaps in place to hold two boards together. It’s an easy two-step process. You can also see the entire process on video. Radiant heat wood floors add comfort and value to any home. Older systems required water filled tubes and water pumps to circulate hot water. There are no jet plane noises from forced air. It eliminates the popping and groans from baseboard heaters or radiators as they expand and contract. It eliminates dusty vent covers and you won’t have dirty air filters to replace. People with allergies breathe much easier. The top half of most rooms or buildings is where most of the heat loss occurs creating a less efficient, more expensive way to heat. C) then blow it around the ceiling where it quickly loses its heat and sinks to the floor. You end up uncomfortable with chilly legs and feet while your head is warm. Once it’s turned off, you immediately notice a difference and feel cool right away. With Laticrete floor heat, it’s electrical, and there is no water involved. If your home’s incoming power isn’t at least 200 amps, consider upgrading before installing radiant heat. Perform circuit testing during installation and while laying the hardwood floor. Ensure the system is working throughout the process. Don’t wait until you’re done to test it. Touching the wood floor will feel like the same warmth as your hand or foot. To make a more accurate estimate, here are some approximate material costs: Wood takes longer to absorb the heat due to its higher R-value than stone or tile. However, it feels warmer under your feet and helps insulate the floor, moderating the room’s temperature. Easiklip’s selection of solid European White Oak solid floors makes the perfect choice to install a radiant heat hardwood floor system.Fill in this QUICK QUOTE form and one of our friendly staff will get you a quote asap!

The instructions in this manual must be followed when preparing and installing LATICRETE Floor HEAT floor warming products. This manual and the installation layout should be made available to all installers and the electrician working on the job. Failure to follow the instructions in this manual may void the warranty. REMEMBER! The installation plan for each area should be attached to this manual and be provided to the homeowner when the installation is complete. 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 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.http://ninethreefox.com/?q=node/16117 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 (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. Refer to installation Instructions for recommended means of routing supply conductors. IMPORTANT INSTALLATION CONSIDERATIONS 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.DON T install LATICRETE Floor HEAT mat under cabinets, built-in appliances, etc.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. DO Clean the floor of all debris before placing the LATICRETE Floor HEAT mat 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 2 ) or 15 watts per square foot (300 mm 2 ). Make sure all components of the system are rated for the same Voltage (120V or 240V). Have all electrical work completed by a professional electrician in accordance with all local and national codes. Connect LATICRETE Floor HEAT products to a Dedicated Circuit. Call our Technical Support Hotline at ext. 235 if you need answers to installation questions, need help solving a problem, or believe that your LATICRETE Floor HEAT mat has been damaged during installation. 3 All electrical connections must be made by a licensed electrician and comply with all applicable building and electrical codes. Failure to do so voids all warranties and claims. Remove any sharp edges or pointed objects that might damage the heating element. Repair all loose boards and fill gaps as needed to assure that the mat will be installed over a smooth, solid surface. (Prepare the subfloor as you would for any conventional ceramic tile installation following all TCNA Guidelines.) The minimum temperature to install LATICRETE Floor Warming is 41 F (5 C). Do not allow any heating element wires to overlap or any supply lead wires to cross, touch, or overlap the element wires at any point. Configuring Laticrete Floor HEAT Mat Cut the fabric mesh between the heating element wires according to the installation layout provided by your distributor. Fabric cutting lines are always below and between the heating element wires. IMPORTANT! AVOID CUTTING OR damaging ANY OF THE HEATING ELEMENT WIRES OR THE INSULATION AROUND THEM. After cutting the desired fabric mesh, carefully and gently bend the wire (avoid twisting the wire) to place the next mat length in the planned direction.OPEN CORNER TURN 180 U-TURN A FAN CUT (ROUNDED CORNER) OBSTACLE CUT 1 Place the mat in open areas and directly in front of key areas (i.e. toilet, cabinetry, etc). LATICRETE Floor HEAT mat can be placed slightly under the base of the toilet if need be. LATICRETE Floor HEAT mat should be placed directly in front of the base of the vanity to heat the toe kick area properly. B Do not heat under items that are fixed to or flush with the floor (i.e. toilet, cabinetry, etc.) B OBSTACLE CUT 2 OPEN CORNER TURN 4 It is essential that a copy of the final installation plan (marked with any changes made in the layout of the system or its electrical connections) is provided to the homeowner after LATICRETE Floor HEAT products are installed. LATICRETE Wire Eye electric wire fault indicator is recommended for use during the installation of all LATICRETE Floor HEAT mat installations. LATICRETE Wire Eye is a device which monitors continuity of LATICRETE Floor HEAT mat(s) during the installation process and notifies the installer if there is a break in the LATICRETE Floor HEAT mat. In the case of lost continuity, an alarm sounds alerting installers to cease installation. In the event LATICRETE Wire Eye sounds, stop and call LATICRETE Technical Service Department at ext. 235 before continuing. For further instructions regarding LATICRETE Wire Eye please see detailed instructions included in product packaging. 1. Verify that materials shipped match materials ordered before unwrapping mats. 2. Measure and record the initial resistance of each element. A. 120 Volts: Test between the hot (Yellow or Black) and neutral (White). B. 240 Volts: Test between the Line 1 (Red) and the Line 2 (Black). Compare each Ohm reading taken in steps 3, 5, 7, and 9 with the initial Ohm readings taken in Step 2. If there is a significant change at any point during or after the installation, stop and call our Technical Service Deptartment. 3. Measure and record the resistance of each element (See Step 2) again after customizing the mat(s). 4. Verify that there are no shorts in the LATICRETE Floor HEAT mat(s) by checking the resistance between the Hot (Line) and Ground. There should not be continuity. Record the final resistance on the Installation Plan. 10. Repeat Step Attach the White Output Label(s) to the end of the corresponding lead wire(s). 12. Place each Silver Output Sticker in an easily accessible place on the Circuit Breaker Box to label the circuit(s) with the electrical description of each mat. White (Lead Wire) and Silver (Circuit Panel) Labels LATICRETE Floor HEAT mats use electrical resistance to generate heat. Resistance is measured in units known as Ohms. The Digital Ohmmeter or Multimeter used must have a scale capable of reading resistance in the range of Ohms. 5 All electrical connections must be made by a licensed electrician and comply with all applicable building and electrical codes. Failure to do so voids all warranties and claims. The LATICRETE details depicted have corresponding Tile Council of North America (TCNA) details listed.

An online project layout tool is available at STEP 2: OBTAIN MATERIALS Broom and Dustpan; LATICRETE Floor HEAT Mat(s); Digital Ohm Meter; Tape Measure; Scissors; Marker; Smooth-sided Trowel or Rubber Float; Notched Trowel (for tile installation); LATICRETE Wire Eye (recommended); Staple Gun (optional); Hot Glue Gun with Glue (optional) STEP 3: PREPARE THE FLOOR Inspect and clean the subfloor or underlayment surface carefully making sure to remove any sharp edges or pointed objects that might damage the heating element. Wipe down the substrate with a sponge that is clean and damp. STEP 4: KEEP THE LABELS Remove the White Output Label and the Silver Output Sticker (the electrical description label and sticker provided on each roll of LATICRETE Floor HEAT) and keep them with the installation information. These will be used to label the leads and the system at the Circuit Panel after the installation is complete. STEP 5: TEST THE SYSTEM RESISTANCE Test and record element resistance of each mat as described in the documentation procedures outlined on page 5. STEP 6: CUSTOMIZE THE MAT(S) To ensure proper installation and coverage, dry cut the LATICRETE Floor HEAT mat to custom fit the room (according to the provided layout) before any thin-set mortar is applied. Be careful not to damage or sever the wires. 8 Check for shorts between the ground and each of the other wires before proceeding. (See documentation procedures outlined on page 5.) LATICRETE Floor HEAT mat(s) can be monitored throughout the installation process with the use of LATICRETE Wire Eye electric wire fault indicator. STEP 8: MARK THE LEAD PATHS While the mat is laid dry in place, mark the desired sensor location, the sensor lead path and the supply lead path back to the control location on the underlayment and on the installation layout. STEP 9: Prepare Groove(s) for Lead(s) In the case local codes require sensor lead paths and supply lead paths to be placed in grooves notched into the subfloor or underlayment, remove mat from work space to avoid the risk of damaging the mat. Do not leave the mat in the area where the groove(s) need to be notched. Completely remove the mat from the working area marked for the sensor, the sensor lead path and the supply lead path. Prepare a groove in the subfloor or the underlayment for the Supply Lead Wire(s) or Supply Lead Conduit (per your local codes). Clean groove thoroughly. STEP 10: SECURE THE MAT LATICRETE Floor HEAT is provided with self-adhesive backing and tape for ease of installation. After the area is cleaned and prepared, simply place LATICRETE Floor HEAT mat(s) in place and apply pressure to adhere to subfloor or underlayment. For increased stability staple the mesh in between the heating element wires. Never staple over element wires. STEP 11: SECURE THE Supply LEADS Secure the supply leads in the groove(s) with hot glue if desired. STEP 12: INSTALL THE LATICRETE Floor Warming Thermostat floor sensor. A hot glue gun can be used to hold sensor in place if preferred. Installing the sensor in a groove may be required by local codes. STEP 13: TEST THE SYSTEM RESISTANCE Test and record element resistance of each mat. Check for shorts between the ground and each of the other wires before proceeding. (See documentation procedures outlined on page 5.) STEP 14: TEST THE SENSOR RESISTANCE Test and record control sensor resistance using an Ohm Meter setting of 20K. The sensor reading should register between 8K 12K. STEP 15: Set Mat in Mortar Option A: Use the flat side of a trowel OR a rubber float to apply a smooth skim-coat of thin-set mortar over LATICRETE Floor HEAT mat. Make sure to use enough mortar to encapsulate the heating element wire in its entirety. Then allow the protective layer of LATICRETE polymer fortified thin-set mortar to set. Option B: Apply a thin coat of LATICRETE 86 LatiLevel self-leveling underlayment (per LATICRETE 86 LatiLevel instructions) to completely encapsulate LATICRETE Floor HEAT mat. Allow to cure per the product instructions. See Data Sheet LATICRETE Self Leveling Underlayment Installation Instructions for more information. REMEMBER: THE SENSOR WIRE MUST NOT CROSS, TOUCH OR OVERLAP ANY HEATING ELEMENT WIRES. 9 All electrical connections must be made by a licensed electrician and comply with all applicable building and electrical codes. Failure to do so voids all warranties and claims. Make sure to use enough mortar to encapsulate the heating element wire in its entirety. Trowel additional thin-set mortar and set tile in one step. NOTE: It is highly recommended that several Ohm readings be taken during the tile installation process to assure that the mat has not been damaged. Use of LATICRETE Wire Eye electric wire fault indicator is also recommended. STEP 16: INSTALL TILE Proceed with the tile installation, making sure to follow all TCNA Guidelines and LATICRETE recommendations for tile setting materials. (BE CAREFUL not to damage the heating element when applying the thin-set with the notched trowel.) STEP 17: TEST THE SYSTEM RESISTANCE After the tile installation is complete, test and record the final element resistance of each mat. Check for shorts between the ground and each of the other wires before proceeding. Run the appropriate gauge wiring (to accommodate the total amperage) through a conduit to the control. Labels of Warning and Caution Warning. Risk of electric shock electric wiring and heating panels contained below the floor.Remove the label above from the manual and affix to the panelboard to indicate which branch circuits within the panelboard supply the space heating that has been installed. Caution! Radiant heating products installed in this area.Remove the label above from the manual and affix adjacent to points of access to concealed areas in which installed heating products are accessible.STEP 19: CONNECT THE CONTROL(S) A qualified electrician should make all connections to the control(s) and the power source. Sensor wires must be connected for LATICRETE Floor Warming Thermostat or any other thermostat to function. The system should also be connected to a dedicated circuit and must be GFCI protected. NOTE: The LATICRETE Floor Warming Thermostat comes equipped with an INTERNAL GFCI to accommodate a load The temperature sensing is accomplished by placing a sensor in the heated area under the flooring surface. This versatile unit can be programmed to operate at varying temperatures for different time periods on a daily basis. LATICRETE Floor Warming Thermostat is equipped with an internal GFCI, available in both 5mA and 15mA. Please contact the LATICRETE Technical Services Department at ext. 235 for further details. The sensor wire should not be placed in the same conduit as the supply leads. LATICRETE Floor Warming Thermostat floor sensor placement LATICRETE Floor Warming Thermostat floor sensor should be installed after the LATICRETE Floor HEAT mat has been secured to the underlayment, but BEFORE it is covered with any mortar or self leveling underlayments. Make sure to place the sensor between the heating element wires without crossing or touching any of the element wires as described in the Step-By- Step Installation Procedures of this manual. Extending The Leads The supply leads extend approximately 12' 13' (360 cm 390 cm) from the LATICRETE Floor HEAT mat. Since the supply lead(s) cannot be spliced in the floor, the LATICRETE Floor HEAT mat should be laid in a pattern that allows the supply lead(s) to run directly to the junction box without crossing or touching any element wires. However, if the supply lead(s) need to be extended, an additional accessible junction box should be set just above floor level. The gauge of the extension wire(s) used should be determined by the electrician to accommodate the amperage of the LATICRETE Floor HEAT mat(s) being installed. Note: Inaccessible extensions or splices are not permitted. Electrical Preparation LATICRETE Floor Warming Thermostat All electrical connections for LATICRETE Floor HEAT products and controls should be done by a professional electrician in accordance with all local and national electrical codes. Multiple Mat Installations If the project requires more than one (1) LATICRETE Floor HEAT mat to be connected to the same control, the supply leads from the LATICRETE Floor HEAT mats should be connected in parallel (not in series) through an additional junction box and extended through the conduit to the thermostat junction box. The gauge of the extension wires used should be determined by the electrician to accommodate the amperage of the mats being installed. (See Section labeled Use of a Contactor and Separate GFCI for further details.) 11 All electrical connections must be made by a licensed electrician and comply with all applicable building and electrical codes. Failure to do so voids all warranties and claims. If the total amperage of a multiple mat system exceeds 15 Amps: A. The LATICRETE Floor HEAT mats and controls should be connected through a contactor in accordance with all NEC and local electrical codes. B. The heating elements must be protected by a separate GFCI. The LATICRETE Floor Warming Thermostat will no longer be providing the fault protection due to the use of the contactor. C. Use a GFCI Breaker capable of handling the total load in accordance with NEC and local codes. Maintenance LATICRETE Floor HEAT has no moving parts and is virtually maintenance-free. The internal GFCI (Ground Fault Circuit Interruptor) contained within the LATICRETE Floor Warming Thermostat should be tested monthly as described in the product s pamphlet to ensure its continued safe operation. If an external GFCI is utilized instead this should also be tested monthly. OPTIONAL: The installation layout may be designed to split the area into different zones. Separate controls may then be used for each zone. This would eliminate the need for a contactor. However, the Total Amperage for EACH control should NOT exceed 15 Amps. Control Wiring Diagram FLOOR SENSOR ECONO INPUT FLOOR SENSOR ECONO INPUT 12 A professional electrician should be called in to trouble-shoot the system. 1. If LATICRETE Floor HEAT fails to heat, make sure there is power delivered to the system and the GFCI (Ground Fault Circuit Interrupter) has not been tripped. The chart on page 8 lists the proper Ohm Readings that should be obtained for each mat size available. This may have been caused by damage to one of the heating elements during the installation process or by changes that were made in the floor structure (condition) after the flooring was laid. The change, no matter how slight (i.e. putting a doorstop in place, etc.) may have damaged the heating element. After locating the possible problem area(s), please contact our Technical Service Department at ext. 235 for further instructions. If there is continuity it is likely that the heating element is damaged and is causing a short in the system. STOP and call our Technical Service Department at ext. 235 for further assistance. A. 120-Volt Product: Test between the hot (Yellow or Black) and Ground (Green) and also between the neutral (White) and Ground (Green). B. 240-Volt Product: Test between Line 1 (Red) and Ground (Green) and also between Line 2 (Black) and Ground (Green). Wait approximately 60 minutes for the floor to warm.When testing the voltage, make sure that the controls are set to ON. If you suspect that the thermostat or timer is faulty, please contact our Technical Service Department at ext. 235 so that we can further assist you in trouble-shooting, if necessary, or arrange for exchange of the faulty product. 13 All electrical connections must be made by a licensed electrician and comply with all applicable building and electrical codes.
