1.0 PRODUCT SPECIFICATIONS

WarmlyYours Heating Cable is designed for new concrete slab floors. It is well suited for large areas like basements, garages and additions.

The Heating Cable is comprised of a dual, multistrand heating element with a primary insulation of Fluoropolymer. The insulated core is then protected with a woven metal braid and an outer jacket of PVC, EPR or Zero Halogen Polyolefin based compound to make it sturdier and to provide corrosion protection. These cables are terminated with 20’ (6.1m) long standard cold leads. The hot and cold junction is uniquely designed to make it durable and flexible.

Available in a wide range of lengths and sizes to suit your requirements, the Slab

Heating Mats and Heating Cables are identified as indicated below.

Application

Indoor Slab Heating

Watts per Sq.Ft. (per Sq.M.)

- Cable spacing inches (mm)

20 W/ft2 (161 to 215 W/m2)

Recommended spacing 3” to 3.5” (76 to 89mm).

Multiplier at given spacing

4 at 3” (76mm)

3.5 at 3.5” (89mm)

3 at 4” (102mm)

2.4 at 5” (127mm)

Formula: Area of Application x Multiplier at given cable spacing = Heated Cable

Length required

Example 1 (English): 100 sq.ft of Slab Heating x 4.0 at 3” spacing = 400 feet of

Heated Cable required

Example 2 (Metric): 9.3 sq.m of Slab Heating x 4.0 at 76mm spacing = 122m of

Heated Cable required

Note: For normal plain bare slabs, stained or stamped use 3” spacing. For application when the slab also has a floor covering like tile or wood, use 5” spacing for a maximum of 15w/sq ft. to meet code requirements.

Please note the above-indicated values are meant as a general guide. Your values may vary depending on a number of factors. Please consult your Account Manager for assistance.

over cable. Duct tape the ends of shovels. Do NOT saw expansion joints, without having lines marked off clearly with spray paint, where installer has verified that

Heating Cables will not be cut. Do NOT damage Cables with heavy equipment, machinery or vehicles.

6. Heating Cables should be separated from other heat sources such as luminaries, and fireplaces.

7. Do not install the Heating Cable below 5˚ F (-15˚ C) ambient temperature.

8. Minimum bending radius of the Heating Cable shall not be less than 10 times its diameter.

9. Minimum spacing of Cables is 3” (76 mm) and maximum spacing of Cables is 5”

(127mm).

10. Twin Conductor Heating Cable has a ground braid (metal sheath) to be connected to ground and 2 conductors which are to be connected to the power supply.

11. Double check the voltage and wattage of the Heating Cable received against the project specifications on your custom installation plan. These are marked on the CSA label of the product. A qualified electrician should connect the Heating

System.

12. Check the conductor, resistance and insulation resistance of the Heating Cable before installing and also after installing. Resistance value should match the value shown in Appendix A and Appendix B. A tolerance of -5% to +10% is allowed.

Insulation resistance must be infinite (500 VDC megger meter required to test).

13. Keep high voltage power wires in a separate conduit from the low voltage sensor wire.

14. Allow sufficient drying or curing period of the slab after installing the Heating

System before energizing the Heating System. (7 day minimum)

15. For easy reference, fix a label at the power distribution board indicating the location of the heating units installed.

3.0 IMPORTANT INSTRUCTIONS BEFORE INSTALLING THE SYSTEM

1. Heating Cable must not cross or overlap itself at any point. Do not install cable runs any closer than 3” on center. This could cause the Cable to overheat, requiring replacement.

2. The Heating Cable length should not be cut or altered under any circumstances. This may cause over heating resulting in damage to the Cable.

3. All heated portion (blue) and factory splice must end up buried completely in the concrete. Ensure none of the heated portion (blue) or the splice (look for heatshrink) enter into any conduit.

4.3 PRE-INSTALLATION PREPARATIONS

1. Review the custom installation plan for the area requiring the Heating System and verify dimensions listed against your actual field dimensions to ensure they match.

2. Confirm the location of the power supply box/Thermostat and sensor against the plan.

3. Select Heating Cable(s) and ensure that the procured Cable is correct according to the requirements in the following section.

4. Check the Slab Heating Cable in the box visually and make sure that it is not damaged. Check voltage, wattage, resistance values from the factory test record and verify that they match the required specifications.

10. Check the resistance and insulation resistance value after laying out Cables.

Check to see if these values are consistent with the pre-install values. Record values in the warranty card on page 13.

11. At this point, the concrete can be poured.

5. Check resistance of the conductor and its insulation resistance with a multimeter/ megohmmeter as soon as it is removed from its packing. Resistance value of the Heating Cable shall match to the value shown in Appendix A or Appendix B.

A tolerance of -5% to +10% is allowed. Insulation resistance should be infinite.

Record it on the warranty card located on page 13 of this manual.

6. The Heating Cable is now ready for installation.

8. Heating Cable should be laid so that the Cables are equally spaced. The distance between two Heating Cable passes should be according to the spacing calculation determined by WarmlyYours (3” to 5” range).

9. Route the power leads through a conduit from the floor to the connection box. If multiple cables are being used, route all power leads through a conduit from the floor to the connection box in the wall. Ensure hot section and factory splice do

NOT get into the conduit

12. Pour the concrete and spread evenly on the reinforcement mesh / grid. The concrete floor or slab thickness shall be about 2” (51 mm) on top of the Heating

Cable. Typical 4” to 6” slabs will have cable located in middle (2” to 3” from finished surface).

13. Ensure the entire Heating Cable, factory splices and thermostat sensor (in metal conduit) are embedded in the cement mortar. The choice and application of building materials should be in accordance with the building material manufacturer’s instructions. (see diagram B)

4.4 INSTALLATION FOR INDOOR CONCRETE SLAB APPLICATION

1. 2” thick polystyrene insulation (or better) should be installed below slab and around perimeter edges.

SNOW MELT MAT

2. Reinforcement mesh on the floor or slab should be strong enough to walk on and not sag or bend.

14. Ensure the correct curing time for drying of construction materials is followed before powering ON the Heating Cables (7 day minimum).

15. Check the continuity, resistance and insulation resistance values after the concrete or mortar is poured. They should be consistent with the values recorded previously.

Record values on the warranty card on page 13 of this manual.

3. Reinforcement mesh should be properly positioned and supported so that it does not get disturbed during the concrete pour. Ensure the Heating Cable is on the reinforcement mesh a minimum of 2” (51mm) below the finished concrete/slab surface.

P N E

4. Surface preparation of the floor is very important. The floor must be completely free of all debris including all nails, sharp metallic objects, wood and construction debris.

Make absolutely sure that there are no objects on the floor that might damage the

Heating Cable.

4.5 OPERATING TIPS

1. Energy consumption will vary depending on ambient temperature and building insulation. For lower energy consumption, use a 7-day Programmable Thermostat control.

2. Energy consumption can be minimized by turning the system OFF when heating is not required, but extra time will be required for the floor to warm up once the system is turned ON again.

3. Avoid placing objects like thick mats, rugs, floor level furniture and mattresses on the heated floor, especially in the area where the floor temperature sensor is located. These restrict the transfer of heat away from the Cables and result in the floor area beneath them being warmer than other areas.

4. Avoid Mats with rubber or vinyl type backing as these may decompose with heat and could stain flooring.

4a. For Two-Pour Installations: The concrete installer pours the first 2” to 3” (51mm to 76mm) of concrete. While this first pour is still wet, rebar or wire-mesh should be placed on top of the first pour. The cables should be attached to the rebar

/ mesh with plastic zip ties, using 3” to 5” (76mm to 127mm) spacing for freeform type cable. At this time, the electrician must route the cold lead(s) thru rigid metal conduit(s) to get back to an accessible junction box(es). Care must be taken by the electrician so that none of the heated section nor the factory splice enters any conduit. This is the best time for sensor placement. Separate conduit should be used to protect the low voltage sensor wire and must NOT be shared with any high voltage cold lead from the Heating Cables / Mats. Once conduits

& sensor(s) are placed, the topping pour of concrete can be finished. Again, the concrete installer(s) must take care not to walk on the hot-cold splice point, and to avoid damaging the Heating Cables with shovels and rakes. Taping up the shovel blades helps make them less sharp. It’s recommended that Mats be placed so the mesh faces up, keeping the wire-side-down to help protect it from the shovels.

4.6 INSTALLATION UNDER CONCRETE

1. Ensure that the concrete contractor has installed a solid base of 4” to 8” (102 mm to 203mm) of crushed rock aggregate base and that it is tamped down and ready for the concrete pour.

2 . It is extremely important that the concrete installer does NOT use any heavy equipment, machinery, or vehicles over the exposed Heating Cable. During concrete pours, it is recommended that care be taken to avoid stepping on the factory splice portion of cable, where the hot section (blue) meets the cold section

(black). This is the location of the factory splice. During this process of installing the heating product and pouring concrete, it is the responsibility of the electrician to use a 500 VDC megohmmeter and a multi-meter to keep checking on the

Heating Cables that are currently being worked on top of, to ensure they have not been damaged, and will be ready for action once the concrete slab has cured.

* Do NOT use 500 VDC megger while personal are still in contact with the wet cement.

3. For installations in basements and warehouses that will include building posts, it is strongly recommended that the concrete installer pre-sleeve for the posts to avoid any and all drilling of the concrete. The Heating Cable must be routed around these sleeves or posts to avoid any direct contact with them. Heating

Cables or Mats must not be allowed to pass thru expansion joint locations. It is recommended that lines are spray painted on the finished concrete surface by the electrician to mark off exactly where expansion joints may be located.

It is the responsibility of the electrician and the concrete installer to coordinate their efforts so they avoid saw-cutting or drilling thru Heating Cables that are no longer visible beneath the concrete. Following the proposed installation plan from

WarmlyYours will help to ensure this process goes smoothly.

5

4b. For Single-Pour Installations: The wire mesh or rebar is first placed by the concrete installer or electrician. The electrician then must attach the Heating Cable to the rebar / mesh with plastic zip ties using 3” to 5” (51mm to 127mm) spacing for free-form type cable. Then the rebar / mesh must be propped up with concrete rubble, wire chairs, or brick pavers to the appropriate depth so that Heating

Cable / Mat ends up 2” to 3” (51mm to 76mm) from finished surface and no deeper. Once rebar / mesh / Heating Cable is all propped up, the electrician must route the cold leads(s) thru rigid metal conduit(s) to get back to an accessible junction box (es). Care must be taken so that none of heated section or factory splice enters any conduit. If a slab-mounted sensor will be used, this is the best time for placement. It should be located in an open area, between 2 runs of cable. Separate conduit should be used to protect the low voltage sensor wire and must NOT be shared with any high voltage cold lead from the Heating

Cables / Mats. Once conduits & sensor(s) are placed, the pour of the concrete can be finished in one step. The concrete installer(s) must take care not to walk on the hot-cold splice and to avoid damaging the Heating Cables with shovels and rakes. Mats should be placed mesh facing up, keeping the wire-side-down, to help protect it from the shovels and rakes.

5. The electrician needs to complete final testing of all the Heating Cables / Mats with a multi-meter and a megohmmeter to verify and record that each Heating

Cable has survived the pour of concrete and is ready for action once the concrete is cured. (7 day minimum)

Slab Heat Troubleshooting Guide

SYSTEM NOT WARMING

1. Do an amp draw test on the cables to verify proper operation.

2. Thermostat/control set at too low of a temperature. Adjust to higher temperature.

Because of the nature of slab heat, any changes in slab temperature will take time to accomplish. Slab heat has a much slower reaction time that floor surface heating.

3. Severe Weather.

a. Extreme outdoor conditions may affect slab temperature. Depending on the insulation values under the slab and around the perimeter of the slab, extreme outdoor temperatures can adversely affect the final temperature of the slab.

4. Insufficient watt density. Verify spacing of product vs the design plan.

a. The more distance between the heating wire, the lower the watts per square foot.

The lower the watts per foot, the less satisfactory the performance. This type of system will have to run longer amounts of time, and may not reach desired temperature.

5. Wrong voltage is being supplied to heating cable. a. Is 120V being supplied to a 240V cable?

b. Is the installed product drawing the correct number of amps?

6. Test ohms of heating product a. Verify proper ohms per roll/cable b. Verify no shorts or open circuits

7. Inspect breaker/reset

8. Inspect wiring and connections inside any junction boxes

9. Test ohms of sensor. Call WarmlyYours to verify value.

NO POWER TO HEATING PRODUCT

1. Test ohms of heating cables/rolls a. Verify proper ohms per roll/cable b. Verify no shorts c. Verify no open circuits

2. Inspect breaker/reset a. Verify proper operation b. Verify proper amperage rating per install plan. Recalculate amp load.

c. Verify proper mA rating of breaker d. Replace defective breaker e. Verify use of dual pole breakers for 240V heaters

3. Inspect Relay panel (if present) a. Inspect/replace any faulty wiring b. Inspect/redo/replace any faulty wiring terminals c. Inspect/replace relay d. Verify proper trigger voltage entering relay panel/trigger relay

4. Inoperative Thermostat a. Verify proper connections and power to controller b. Verify proper voltage to controller c. Verify voltage going into controller equals voltage exiting controller d. Verify voltage of heating product matches that supplied to controller.

e. Verify proper setup/programming of controller f. Test/inspect sensor/s for proper operation (see troubleshooting guide for controller) g. Replace defective controller or sensor

5. Wrong voltage is being supplied to heating cable. a. Has 240V been supplied to a 120V product? If so, test ohms of heating product.

b. Do the ohms match the data sheet for installed product?

c. Repair/replace damaged heating product.

6. Inspect wiring between breaker box and control, between control and sensor/s, control and relay panel (if present), and between relay panel and any junction box/es.

7. Inspect heater connections inside all junction boxes.
