Introduction

General Instructions

The Green Cable Surface XL can be installed either in an uncoupling membrane designed for use with a heating cable or with FLEXTHERM’s white colored Universal Snap-in Gauges designed specifically for this cable.

IMPORTANT: The subfloor must meet construction standards and be strong enough to support ceramic tile or natural stone. Refer to the membrane manufacturer to know which supports are compatible for an installation with a heating cable, and to the Tile Council of North America publications (www.tileusa.com) for installation standards.
IMPORTANT: Vacuum and clean any mortar residue that could prevent the installation of the cable between the membrane’s studs.

This product was designed to be installed in an uncoupling membrane with a minimum regular spacing of 7.6 cm (3 in) and a maximum regular spacing of 10.1 cm (4 in) depending on the membrane.
It is also possible to install the cable on other types of supports (concrete, plywood, etc.) with FLEXTHERM’s white colored Universal Snap-in Gauges (see the section “On other types of surfaces with gauges”).

Room Measurements Verification

IMPORTANT: Verify your measurements and recalculate the net heated surface before installing the cable to make sure you have the proper cable length for the project. Refer to the coverage table on the cable’s box to validate your measurements.

IMPORTANT: Never connect a cable while it is on the spool. To test the cable, follow the “Cable verification” procedure.

Cable Verification

The FLEXTHERM seal on the cable warrants the integrity of the cable. The cable cannot be returned if the seal is broken. As a quality assurance measure, each cable has been subjected to a 1,500 V dielectric test and a resistance test.
Before removing the seal and installing the system, the cable insulation and resistance should be verified to ensure the cable conformity. You will have to verify the cable integrity two more times during the installation: once the cable is secured to the floor and before the flooring is installed. These tests are conducted three times to make certain that no damage was caused to the cable during the different stages of the installation.

Resistance Verification

Use an appropriate multimeter to measure the resistance between the black leads. If an automatic multimeter is used the reading will be taken instantly. If the multimeter is not automatic, set it to 200 Ω for a cable under 200 Ω or at the higher value for a cable over 200 Ω. The resistance value of the cable is indicated on the label attached to the end of the cold lead. Compare the test result with the resistance indicated on the label.
Record the results on the limited warranty card. The measurement should be similar to the resistance indicated on the cable label (± 10%). The cable’s resistance was established in an environment at 20°C (68°F). If you obtain a reading that does not correlate with these parameters contact FLEXTHERM customer service at 1 800 353-9843.

Insulation Verification

Use a megohmmeter to verify the cable insulation integrity. Connect the instrument’s black cable to the system ground wire (the green lead) and the red cable to one of the heating elements (black leads) and then send a 1000 V current. This result should be “infinite” ohms. Should there be a current leakage between the heating element and the insulation, the appliance will indicate a result between 0 and 500 MΩ.

Record the Results

IMPORTANT: Record the results obtained for these two tests on the limited warranty card every time you perform them: before breaking the seal, after the cable is secured to the floor and before the flooring is installed. These results must be recorded on the limited warranty card in order to preserve the system’s limited warranty.
Should the results obtained not comply with cable specifications, do not break the cable seal and contact FLEXTHERM customer service at 1 800 353-9843.

Preliminary Electrical Installation

Circuit

Floor heating systems should be connected to electrical circuits dedicated to heating. The amperage drawn by the cable sets, as indicated on the cable labels, will determine the required circuit intensity. Please take note that the maximum load that can be supported by the FLEXTHERM thermostat is 15 A.
If your system requires more than 15 A, you may need more than one circuit. For a load greater than 15 A, a system with an expansion unit or a relay is required. A FLEXTHERM thermostat can control an unlimited number of expansion units.
For further information regarding their connection please refer to the literature included with those products, also available on the FLEXTHERM website at www.flextherm.com.

Electrical Connection Box

Determine where the thermostat connection box will be installed. It should be in an accessible location in the room where the system will be installed and at an appropriate height.
Use an expanded connection box or a 4 in x 4 in box with knockout holes for conduits for the system connection (plan one connection box for each 15 A circuit).

Conduit

(For all the details, refer to your local electrical code.)
A conduit approved for electrical wiring, inside which the non-heating portion of the cable (cold lead) will be inserted, must be installed between the electrical box and the floor.

• Unless approved for this application, electrical metallic conduits are not allowed in wet environments (ex.: shower).
• PVC conduits are allowed only in walls that do not contain thermal insulation.
• The ends of the conduit must be deburred and bushings must be installed to protect the cable against any mechanical damage.
• Conduits must be adequately secured.

Fish Cord

Before installing the gyproc, install a temporary fish cord in the wall, between the floor and the electrical box. When installing the probe on the floor, use this cord to pull the probe wire to the thermostat. The probe wire must be run outside the conduit containing the cold lead, outside the electrical box and be inserted in the opening provided for this purpose on the thermostat’s base.

IMPORTANT: Connect the cable to the thermostat only once the cable has been installed and covered.
Note: Keep ends of the cold lead dry before and during installation.

Cold Lead

The cold lead is flat and black, is 2.4 m (8 ft) long and is connected to the heating cable with a mechanical joint. Just like the heating cable, the mechanical joint must be installed on the floor and covered with the selected mortar.
Since the joint’s diameter is bigger than the heating cable’s, it will be inserted, if needed, in a groove in the membrane (validate with the membrane manufacturer’s instructions) in order to avoid unevenness when the floor covering is installed or in the subfloor if using Universal Snap-in Gauges.

Cable Installation

IMPORTANT!
Before starting installation, take note that…

• The cable will be installed at a minimum distance of:
  • 5 cm (2 in) from the base (toe-kick) of a fixed furniture or cabinet, toilet, patio door, bath or shower step;
  • 5 cm (2 in) from any wall;
  • 15 cm (6 in) from drains;
  • 20 cm (8 in) from any other heating system secured to the floor or in contact with the floor (this does not apply to a convection type heating appliance).
• The cable must be spaced at least 13 mm (1/2 in) from any exposed combustible surface.
• The cable cannot be overlapped, crossed, cut, shortened nor modified.
• The spacing between the cable runs must remain unchanged throughout the installation and must never be smaller than 7.6 cm (3 in) or larger than 10.1 cm (4 in) if installed in an uncoupling membrane; the cable must be installed at a regular spacing of 7.6 cm (3 in) if installed with gauges.
• Cables must be installed in runs of less than 3 m (10 ft) long. Divide the room in smaller sections if it exceeds 3 m (10 ft).
• The uncoupling membrane must be installed before inserting the cable according to the membrane manufacturer’s instructions.
• IMPORTANT: to insert the cable into the membrane, use a non-cutting tool such as a wooden trowel.
• Mortar should be used according to the membrane manufacturer’s recommendations.
• All the heating portion of the cable (including the mechanical joint) must be secured to the floor and covered with mortar. The heating cable should never be, under any consideration, installed in/on walls.
• The system must not be installed under fixed furniture or where air does not flow freely. It should never be installed in closets, wardrobes, over walls or partitions nor over cabinets or in a ceiling.
• The heating cable should never be installed over an expansion joint.
• The installation of the system should not be performed under 0°C (32°F) ambient air temperature.

Installation Plan

Above all, plan your installation while taking into account the above mentioned guidelines. It is recommended to make an installation plan in order to foresee direction changes, obstacle skirting, buffer zones, etc. Buffer zones are areas that are not essential to heat (i.e. behind the toilet, behind a door, or any other low traffic area) that can accommodate any excess cable.
Using a suitable marker or tape, draw the obstacles to be bypassed directly onto the membrane or sub-floor.

Plan the installation to fit the entire cable in the room: the heating cable shall not extend beyond the room or area in which it originates.
Ensure that the buffer zones are easily accessible to accommodate any excess cable while abiding by all the installation instructions. If multiple cables are required for the installation, each run of the cable should be carefully planned to ensure that the spacing between the cables is always met.

Rooms Longer than 10 Feet

1. Do a small detour to break up the cable run.

2. Ensure the chosen spacing is respected all around.
   

3. Change direction if you need more flexibility to get closer to the wall.

Installation with Two Cables

1. End the installation of the first cable by the wall, so that the second cable nestles in easily.

Proper Spacing to Walls and Fixed Objects

1. Change directions so the cable can be installed to the closest spacing allowed from walls and fixed furniture.

Bathroom Example

1. Buffer zones.
2. Change direction because the cable is too close to the podium.
3. Gauges must always be perpendicular to the cable runs.

Two Installation Systems

The Green Cable Surface XL can be installed two ways:

1. In an uncoupling membrane designed specifically for heating cable and installed according to the membrane manufacturer.
2. On traditional surfaces such as plywood and concrete using FLEXTHERM’s white colored Universal Snap-in Gauges specifically designed for the Green Cable Surface XL.

On an Uncoupling Membrane

IMPORTANT: This product was designed to be installed in an uncoupling membrane with a minimum regular spacing of 7.6 cm (3 in) and a maximum regular spacing of 10.1 cm (4 in) or usually at every three (3) studs on a membrane. Spacing can never be modified throughout the installation.

Membrane Installation

Follow the membrane manufacturer’s installation instructions and recommendations.

Cable Installation

To insert the cable between the membrane’s studs, apply a light pressure using a non-cutting tool such as a wooden trowel. When changing directions and contouring studs, always make sure the cable respects a minimum radius of 13 m (1/2 in).
Install the cable in the membrane at a regular spacing at every three (3) studs. Be careful not to damage the cable when inserting it into the membrane.

General Guidelines

IMPORTANT: The subfloor must meet construction standards and be strong enough to support ceramic tile, natural stone or self-leveling underlayment. Refer to Tile Council of North America publications (www.tileusa.com) for installation standards.

Whatever the selected support, the floor surface must be clean, flat, smooth and free of protruding nail or screw heads or other materials that may damage the cables. Always ensure that the selected sub-floor is compatible with mortars or self-leveling underlayment.

Compatible Sub-Floors

Plywood and Cement Board
FLEXTHERM Floor Warming and Heating Systems are installed directly on a plywood surface and cement board without any specific floor preparation, other than the general instructions mentioned previously.

Structural Concrete Slab (Condo Tower)
FLEXTHERM strongly recommends insulating the concrete slab on the surface, between the slab and the heating cable, in order to limit heat loss in the concrete slab and around the perimeter of the room where the cable is installed. It is important to always refer to the building code relating to a slab’s insulation.

Concrete Slab on an Existing Floor (Basement, Single Family Home)
For non-insulated slabs, FLEXTHERM strongly recommends insulating the concrete slab on the surface in rooms where a cable is being installed.
For insulated slabs, in cases where only parts of the slab will be heated, it is recommended to insulate the slab on the surface in those areas. It is important to always refer to the building code relating to a slab’s insulation.

Ceramic
Refer to the mortar or self-leveling underlayment manufacturer to adequately prepare the sub-floor to ensure proper adhesion.

Acoustic Membrane
Install the membrane following the manufacturer recommendations. The heating cable is to be installed over the membrane, which must be properly glued to the sub-floor prior to installing the cable.

Anti-Fracture Membrane
In the case of membranes not specifically designed for heating cable installation, the heating cable is generally installed over the membrane. However, certain manufacturers recommend that the cable be installed under the membrane. Always check with the manufacturer before proceeding with the installation.

Mortar Bed (Sand Coat)
The Green Cable Surface XL and the floor probe must be installed on top of the mortar bed. To ensure the adhesion of the installation gauges, the mortar bed must be smoothed with a flat trowel in order to obtain a surface that is smooth and uniform, not granular. Should the surface be too granular for the hot glue, glaze the mortar bed with mortar.

Scratch Coat
To avoid any risk of damage, always glaze the mesh to obtain a smooth surface prior to installing the cable. Gauges are glued using hot glue on the glazed surface.

Gauge and Cable Installation

Use a hot glue gun to secure the gauges to the subfloor (gauges can also be nailed, stapled or screwed). Hot glue sticks are included in your kit. For maximum adherence, apply hot glue uniformly under the gauges. Never touch the cable with the glue gun tip. It is suggested that the glue gun be rested on a piece of cardboard during installation.
Install the gauges as the work progresses by joining them together.

Slide the cable through the circular shapes by applying a slight pressure. Apply moderate tension on the cable allowing it to remain parallel. When inserting the cable in the gauges, or changing the cable direction, ensure that the cable maintains a minimum 13 mm (1/2 in) radius curve.

To get around obstacles such as diagonal walls, fixed furniture, etc., install the gauges in such a way that they follow the shape of the obstacle. Gauges should always remain parallel to each other, perpendicular to the cable.
The cables should be stabilized at regular one-meter intervals (every 3-4 feet). Snap together the required number of gauges and insert them upside down under the cable runs so the cables don’t snag in them.
Once inserted, turn them over and slide the cables between the circular forms. Move the gauges slightly to one side making the cable more stable and secure them to the floor.
Once the cable is entirely secured, glue the tip of it to the floor with hot glue. Do not touch the cable with the tip of the glue gun.
A typical installation of the FLEXTHERM heating floor system in a bathroom is shown.

Wet Environment Installation

The Green Cable Surface XL can be installed in a wet environment such as a European style shower floor or sauna with a ceramic or natural stone floor.* However, additional precautions must be observed.

• The thermostat must be located at least 1 m (3 ft 3 in) away from the wet zone so that it cannot be reached by a person in that area.

• The shower must have its own cable.

• Drill the hole in the wall 15 cm (6 in) above the floor to avoid the waterproof membrane.

• The installation must be performed in accordance with all other instructions listed on page 3, such as minimum distance from the drain, restrictions for installing the cable in walls, etc.

• Applications must be validated with local and/or national electrical codes.

Floor Probe Installation

Insert the thermostat probe in the membrane or on the subfloor according to the type of installation. The probe should be centered between two heating cables.
For an installation in a membrane, insert the probe wire between studs between two cable runs and curve the end of the probe at 90 degrees between two studs so it is centered between the two heating cables.
Place the probe inside the heated zone, at a distance of 30 to 60 cm (1 to 2 ft) from the perimeter. Do not cross the probe wire over the heating cable. The probe should be placed in a neutral location, far from any other heating or cooling sources.

Pull the probe wire using the fish cord previously installed or using fish tape, outside the conduit and electrical box. Verify its integrity with an appropriate multimeter (refer to the thermostat installation guide for more details).

Securing the Cold Lead and the Probe to the Connection Box

To make it easier to pass the cold lead through to the connection box, wrap the label around it. Tape the label with electrical tape to maintain it in place. The cable identification label must remain on the cable. Removing it will void the cable’s limited warranty.

Pull the cold lead in the conduit using fish tape, if required.
If necessary, cut any excess of the cold lead while keeping the product’s identification label.
To do so, remove the black sheath all the way to the desired spot without damaging the conductors, slide the identification label over the conductor and cut the excess wire.
Install a protective plate if required at the bottom lathe of the wall.

Cable Verification

Once the cable installation is completed, once again verify the cable’s integrity as explained in the section “Cable Verification”. Record the results on the limited warranty card. Should the cable have been damaged during installation, do not install the flooring. Contact FLEXTHERM Customer Service at 1 800 353-9843.

System Protection

Between the installation of the cable and the laying of the flooring, protect the cable with cardboard or similar soft material and restrict access to the area if the cable is being installed using gauges.
It is recommended to take photographs of the cable installation before installing the flooring. These pictures will prove that your installation meets all the standards and written instructions and will be a useful reminder should you have to renovate.

Floor Covering Installation

Once the cable has been installed and tested, proceed to the application of the mortar or self-leveling underlayment and the installation of the floor covering. Please refer to the manufacturer’s recommendations in regards to the use of their product with floor heating systems.

General Guidelines About Mortars and Self-leveling Underlayment

Whatever the selected technique, the heating portion of the cable, as well as the mechanical joint and floor probe, must be completely embedded in the mortar or self-leveling underlayment.

WARNING: The floor covering must be in direct contact with the mortar in which is embedded the heating cable. Make sure there is an adequate transfer of mortar according to current standards.
WARNING: Precautions to Take While Installing the Flooring
When mortar is used, never hit the trowel on the heating cable to remove excess mortar from the trowel: cables could be damaged. Use a sponge or a wet cloth to remove excess mortar as you lay the tile: do not use a utility knife or the edge of your trowel. These tools could damage the heating cable.
During all operations, lay tools and materials (buckets, etc.) on a piece of cardboard instead of directly on the cables.

Note Regarding the Floor Stability

Floor stability will vary according to the type of flooring installed and its components. Mortar manufacturers and the Tile Council of North America (TCNA) strongly recommend the use of expansion joints on the perimeter of the room and obstacles as well as across the room (reference TCNA article EJ-171).
Should you require more information regarding tile setting or sub-floor construction, contact the TCNA (www.tileusa.com).
Please note that the following instructions do not represent a complete flooring installation guide. They only offer general guidelines to be observed while installing over a floor heating system. Always follow the flooring manufacturer’s directions in regards to the use of their products.

Floor Covering Installation (With an Uncoupling Membrane)

See the membrane manufacturer’s recommendations for the types of compatible mortars as well as instructions on the floor covering installation.

Floor Covering Installation (With Gauges)

1. Polymer-modified mortar glazing technique

   • Ceramic or natural stone flooring
     This technique involves glazing the cables with the same type of mortar that will be used for the floor covering. A thin layer of polymer-modified mortar is spread over the cable (in the same direction as the wire) with a flat trowel. Pull the trowel at a 45° angle using a little pressure. Spread the mortar in a way that the space between the cables is completely filled. It is not necessary to fully cover the gauges.
     Once the glaze is set, proceed with laying the tile as per the manufacturer’s recommendations.

2. Polymer-modified self-leveling underlayment glazing technique – All types of flooring
   NOTE: The Green Cable Surface XL can only be covered with a self-leveling underlayment if it is installed with Universal Snap-in Gauges.
   IMPORTANT: The use of a soft floor covering is not recommended with the Green Cable Surface XL.
   

Make sure that gauges are secured to the floor surface and that cables are stabilized at 1 m (3ft) intervals to prevent them from floating when the self- leveler is applied.
Using a smooth scraper, spread a thin layer of self-leveling underlayment. Once the underlayment is set, proceed with laying the floor covering as per the manufacturer’s recommendations.

Cable Verification

Once floor covering installation is complete, verify the cable’s integrity one more time, as described in the “Cable Verification” section at the beginning of this guide. Record the results on the warranty card.

Connection to the Thermostat

DANGER: SEVERE RISK OF ELECTROCUTION. Turn off the power of the designated electrical circuit prior to connecting the system controls.

Thermostat to Use

Use FLEXTHERM thermostats to operate the system. These thermostats are equipped with a class A ground fault circuit interrupter (GFCI) that will protect the system in case of fault. To preserve the system’s warranty the use of a thermostat equipped with a class A GFCI (5 mA) is required.

Single-Circuit Installations

Connect the system’s green wire (ground) to the terminal in the connection box. Proceed as per the instructions in the electronic thermostat installation manual. Identify the circuit on the electrical panel. Complete and apply the warning label.

Multiple-Circuit Installations

Should your installation require more than one circuit, you will need one thermostat, as well the required number of expansion units or relays. For their connection, refer to the instruction guide provided with the thermostat, the expansion units or the relays. Identify the circuits on the electrical panel. Complete and apply the warning label.

Keep Installation and User Guides

Please keep the thermostat instructions in a safe place for future reference.

System Start-up

Curing Period

Do not turn your system on immediately. The system can be operated only after the mortar or self-leveling underlayment has completely cured. This waiting period is essential to ensure that the mortar or self-leveling underlayment is properly set. Refer to your manufacturer’s instructions to verify the curing time for the product you are using (generally 28 days).

Use of Rugs

Do not lay a rug on a floor equipped with a heating system. The heat that would get trapped could alter your rug or flooring. The use of a bath mat is acceptable, as long as it is taken off the floor once the bath period is over.
For the same reason, do not lay a piece of furniture under which air cannot freely circulate on flooring under which there is a floor heating system.

Repair

Should the floor covering need repair, proceed with caution. Always turn off the power supply to the heating cable before removing the piece of flooring that needs to be repaired. For ceramic or natural stone floors, gently scrape off the grout around the tile to be replaced to a maximum depth of 3 mm (1/8 in) and break the tile with a hammer starting from the center (do not use excessive force which could damage the cable). Without damaging the cable, carefully scrape off the motor with a chisel or a scraper.
Should the cable be damaged in the process and/or the GFCI be set off, the system is out of service and should not be activated. THE CABLE CAN BE REPAIRED. A repair kit (product code: FSK-03) is available from your FLEXTHERM dealer.
Never attempt to repair a cable located in a wet area, contact FLEXTHERM Customer Service at 1 800 353-9843.
FLEXTHERM’s Floor Warming and Heating System is maintenance free. Should it stop heating, immediately contact FLEXTHERM Customer Service at 1 800 353-9843.
