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 Polyolen 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 100% fool proof.

The Snow Melting Mat is a cable in mat construction (for snow melt applications)
which consists of the Heating Cable taped on a Polypropylene (PP) mat. The Heating
Cable is laid in a serpentine fashion so that it is equally spaced and distributed on
the (PP) mat.

Available in a wide range of capacities and sizes to suit your requirements, the Snow
Melting Mats and Heating Cables are identied as indicated below.

feet of Heated Cable required
Example 2 (Metric): 9.3 sq.m of Outdoor Snow Melting x 4.0 at 76mm spacing =

37.2m of Heated Cable required

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

3.0 IMPORTANT INSTRUCTIONS BEFORE INSTALLING THE SYSTEM

1. Heating Cable must not cross or overlap itself at any point. 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. The cold lead can be cut /extended with a conventional splice, inside of an
accessible junction box (weatherproof if outdoors).

9. 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.

10. Double check the voltage and wattage of the Heating Cable received against the

project specications on your custom installation plan. These are marked on the
packing box of the product. A qualied electrician should connect the Heating
System.

11. Check the continuity, resistance and insulation resistance of the Heating Cable

before installing and also after installing. Resistance value should match the
value shown in Appendix A on page 12. A tolerance of -5% to +10% is allowed.
Insulation resistance must be more than 10 megohms.

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

13. Allow sucient drying or curing period of the oor / slab / concrete / asphalt after

installing the Heating System and before energizing the Heating System.

14. For easy reference, x a label at the power distribution board indicating the

location of the heating units installed.

WARNING

15. The Cable must NOT be shortened or cut in any manner or subjected to strain

at the splice joint.

16. NEVER power up Heating Cables prior to being buried in concrete, asphalt or

in mortar (even for testing purposes). This will prevent premature failure of the
Heating Cable.

4.1 TEMPERATURE CONTROLLER & SENSOR

We recommend a standard Programmable Thermostat with a temperature sensor
specially designed for control of the Heating System.

WARNING

Heating Cable should be connected to a Ground Fault Circuit Interrupter (GFCI)
equivalent having a rated residual operating current not exceeding 30mA. Consult a
qualied electrician.

The sensor normally comes with a lead wire of 15 feet (4.5m) in length. Thermostat
sensor location shall be centered between two adjacent runs of Heating Cable within
metal pipe or conduit to allow for replacement. Do not position Thermostat sensor
closer than 1.5 inch (38 mm) to Heating Cable. Sensor cable shall be routed to the
Thermostat located in the wall at suitable operating height. Always install Thermostat
indoors, even when used in conjunction with exterior slab heating.

Do not allow any other Heating Cable to overlap with the sensor cable.

The details of the thermostats and installation guidelines are given in the instruction
manual provided with the Thermostat.

4.2 ELECTRICAL PROVISIONS FOR THE SYSTEMS

The Heating System installation wiring shall be in accordance with the National Electric
Code and any applicable local codes. Controls and accessories recommended for
use along with the Heating Cables are listed below:

• Floor Sensing Temperature controller / Thermostat

• GFCI (Ground Fault Circuit Interrupter)

• Dedicate Circuit Breaker(s) for all heater circuits

• Plastic or wire zip ties

In case the GFCI trips during normal operation, and cannot be reset, there is likely a
fault in the Cable. No attempt should be made to re-energize the system. The GFCI
must not be bypassed under any circumstances. Consult a qualied electrician.

The location of the Thermostat junction box shall be about 4’ (1.2m) high from the
oor for easy access. The oor sensor wire and the Heating Cable cold leads shall be
routed to the Thermostat / power connection box in separate conduits.

If the Heating System has a load below 1,750W at 120V or 3,500W at 240V based
on thermostat power rating, it may be connected directly to an electronic thermostat
as shown in Diagram A which gives a typical scheme of the electrical system. If the
Heating System has a load more than the thermostat power rating, consult your
WarmlyYours Account Manager.

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 eld dimensions to ensure they
match.

2. Conrm 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 specications.

5. Check resistance of Heating Cable 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 on page 12. A
tolerance of -5% to +10% is allowed. Insulation resistance shall be more than 10
Megohms. Record it on the warranty card located on page 22 of this manual.

6. The Heating Cable is now ready for installation.

7. 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. No heating cable shall be covered by any surface­mounted equipment.

8. Route the power leads through a conduit from the oor to the connection box. If
multiple cables are being used, route all power leads through a conduit from the
oor to the connection box in the wall.

9. 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 22.

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

11. Pour the concrete and spread evenly on the reinforcement mesh / grid. The

concrete oor or slab thickness shall be about 2” (51 mm) on top of the Heating
Cable.

12. 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.

4.4 INSTALLATION FOR INDOOR CONCRETE SLAB APPLICATION

1. Reinforcement mesh on the oor or slab should be strong enough when walked
on for installation of the Heating Cable.

2. 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 nished concrete/slab
surface.

3. Surface preparation of the oor is very important. The oor 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 oor that might
damage the Heating Cable.

4. Start installing Heating Cable from the location of power connection box.

5. Roll out the Heating Cable. Secure it to the reinforcement mesh or grid using

plastic zip ties (supplied by installer).

6. Heating Cable should be laid 3” (76mm) away from the wall perimeter.

13. Ensure the correct curing time for drying of construction materials is followed
before powering ON the Heating Cables.

14. 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 22 of this manual.

WARNING

The heated cable spacing is mandated to generate a maximum of
15Watts/ft2 (161Watts/m2) of output in applications where a oor covering, such as
carpet, tile, or wood, is placed over the slab.

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

3. Avoid placing objects like thick Mats, rugs, oor level furniture and mattresses
on the heated oor, especially in the area where the oor temperture sensor is
located. These restrict the transfer of heat away from the Cables and result in the
oor 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 ooring.

5.0 INSTALLATION FOR SNOW MELTING

5.1 CONTROL OF SNOW MELTING SYSTEM

A control suitable for Snow Melting systems with pavement mounted or aerial
mounted sensor should be used for Snow Melting applications.

5.3 INSTALLATION UNDER ASPHALT

1. Ensure that paving contractor has a solid base of 4” to 8” (102 mm to 203 mm) of

crushed rock aggregate tamped down and ready to receive the asphalt.

2. It is extremely important that the paving installer does NOT use any heavy

equipment, machinery, or vehicles over the exposed Heating Cable. Any tracked
mechanical spreaders or dump trucks must be prohibited from running over
exposed Heating Cable.

3. During this process of laying asphalt, installing the heating product, and

laying more asphalt, it is the responsibility of the electrician to use a 500 VDC
megohmmeter and a multi-meter to continuously check the Heating Cables that
are being worked on top of, to ensure they have not been damaged.

4a. The paving installer should lay down the binder / base coat of asphalt and roller it

smooth. The paving installer must decide if this binder coat of asphalt is allowed
to cool before nishing with the top coat of asphalt. This should be coordinated
with the installer of the Heating Cable or Mats. When working on top of hot
asphalt, please consider pre-making “wire mesh heating Mats”. This means
rolling out the reinforcing wire mesh (provided by electrician) and pre-attaching
the Heating Cable to it using wire ties (like rebar wire ties) that will not melt from
the hot asphalt. These “wire mesh heating Mats” could be left in the yard next
to the driveway while the rst binder coat is poured. While the asphalt is still hot,
two people could carry / drag each “wire mesh heating mat” over the hot asphalt,
have it ipped over so that it is wire-side-down / mesh-side-up, and then staked
down to the hot binder coat (stakes provided by electrician).

4b. If the paving installer decides to let the binder / base coat of asphalt cool prior

to nishing with the top coat, then wire mesh is only needed for free-form type
Heating Cable installations. WarmlyYours Snow Melting Mats may be staked
down to the binder coat without using any wire mesh (stakes may only pierce the
black plastic mesh, and should never make direct contact with the Heating Cable
itself). Again, it’s recommended that the Snow Melting Mat be laid down so it
is wire-side-down / mesh-side-up, to help protect it from damage by shovels.
When installing free-form type Heating Cable, stake wire mesh down to the
binder / base coat rst, and then attach the Heating Cable to it using wire ties.
This means it is wire-side-up / mesh-side-down, so extra care must be taken by
the paving installer to avoid damaging the Heating Cables with shovels or rakes
used to spread the top coat of asphalt.

5. Once the heater cables are in place, the electrician must route the cold lead(s),
(20 ft (6.1m) provided per each Mat / Cable) through rigid metal conduit(s) to get
back to an accessible weatherproof junction box(s). The electrician may supply
junction boxes which can be accessed from above, so the rest of the box is
buried to avoid damage by lawn mowers and/or vehicles. Care must be taken by
the electrician so that none of the heated section of Cable enters the conduit(s).
If a slab-mounted snow sensor will be used, this is the best time for placement.
It should be located in an open area, away from trees or bushes, so that snow
will easily fall directly on it. 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.

6 . Once the Heating Cables and conduits are in place, and are attached by the

above methods listed, the nal top coat of asphalt may be poured. At least
2” (51mm) of material must cover the Heating Cable. The paving installer will
be required to spread this around evenly with shovels and rakes. Shovels
should be duct taped so the blade ends are less sharp. Again, the topping coat
should be spread manually to avoid use of heavy machinery. The only time it is
acceptable to use a mechanical asphalt spreader would be when it can straddle
tire track coverage used for longer sloped driveways. Tire track coverage allows
the spreader machine to be used without it ever making any direct contact with
the Heating Cables.

7. Once the top coat of asphalt is spread over the Heating Cables evenly with at
least 2” (51 mm) thick coverage, it may be rolled over with the steam roller to
nish / atten the driveway. Again, each Heating Cable / Mat must be tested
with a multi-meter and 500 VDC megohmmeter to verify that they have not been
damaged, and to ensure they will be ready for activation (nal test) after the
asphalt has cured. These values should be recorded on the warranty card on
page 22.

5.4 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
transition portion of cable, where the hot section (green) 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.

3. For installations in stairs and ramps that will include hand rails, 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 nished concrete surface by the electrician to
mark o exactly where expansion joints may be located. It is the responsibility of
the electrician and the concrete installer to coordinate their eorts 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.

4a. For Two-Pour Installations: The concrete installer pours the rst 2” to 3” (51mm

to 76mm) of concrete. While this rst pour is still wet, rebar or wire-mesh should
be placed on top of the rst pour. The Snow Melting Mats / Cables should be
attached to the rebar / mesh with plastic zip ties, using 3” to 4” (76mm to 102mm)
spacing for free-form type cable. At this time, the electrician must route the cold
lead(s) thru rigid metal conduit(s) to get back to an accessible weatherproof
junction box(es). Care must be taken by the electrician so that none of the
heated section enters any conduit. If a slab-mounted snow sensor will be used,
this is the best time for placement. It should be located in an open area away
from trees or bushes so that snow will easily fall directly on it. 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 nished. 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. Like with asphalt, it’s recommended
that Mats be placed so the mesh faces up, keeping the wire-side-down to help
protect it from the shovels.

4b. For Single-Pour Installations: The wire mesh or rebar is rst 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 4” (51mm to 76mm)
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 nished
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 weatherproof junction box (es). Care must be taken so that none
of heated section enters any conduit. If a slab-mounted snow sensor will be
used, this is the best time for placement. It should be located in an open area,
away from trees or bushes, so that snow will easily fall directly on it. 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 nished 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 nal 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. These values must be recorded on the warranty card on page 22.

7

5.5 INSTALLATION UNDER PAVERS (STONE OR BRICK)

1. Ensure that there is a solid base of 4” to 8” (102mm to 203mm) of crushed rock
aggregate base and that it is tamped down and ready to receive the mortar pour.

7. The paver installer(s) must take care not to walk on the hot-cold factory splice
and to avoid damaging the Heating Cables with shovels or rakes. Mats should
be placed mesh facing up, keeping the wire-side-down, to help protect them from
the shovels.

2. It is extremely important that the paver installer does NOT use any heavy
equipment, machinery, or vehicles over the exposed Heating Cable. During the
paver installation process, it is recommended that care be taken to avoid stepping
on the hot-cold factory splice portion of cable (green meets black). It is the
responsibility of the electrician to use a 500 VDC megohmmeter and a multi-meter
to continuously check 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 mortar pour has cured.

3. For installations in stairs and ramps that will include hand rails, it is strongly
recommended that the paver installer pre-sleeve for the posts to avoid any and all
drilling of the mortar. The Heating Cable must be routed around these sleeves or
posts to avoid any direct contact with them. It is the responsibility of the electrician
and the paver installer to coordinate their eorts so they avoid saw-cutting or
drilling thru Heating Cables that are no longer visible beneath the mortar.

4. The paver installer or electrician should place wire mesh (like would be used in
concrete) down on top of the crushed rock aggregate. The mesh should be staked
down rmly to the crushed rock so it remains at. Next, the Heating Cable or Mats
should be attached to the mesh using wire ties to maintain proper depth and
spacing, 3” (76mm) for free-form type Cable. Reference the WarmlyYours custom
installation plan provided with quotation so that this process goes smoothly.

5. At this time, the electrician must route the cold lead(s) thru rigid metal conduit(s),
to get back to an accessible weatherproof junction box(es). Care must be taken
by the electrician so that none of the heated section (green) enters any conduit.
For this type of application, we recommend using an aerial mounted snow sensor
to avoid having to cut around a circular slab mounted sensor (this could cause
a trip hazard or premature paver crumble). Once the conduit(s) is in place, the
product is ready to receive the mortar pour.

8. The electrician needs to complete nal 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 mortar, and is ready for action once the mortar is
cured. These values must be recorded on the warranty card on page 22.

WARNING

Brick and Stone Pavers must NOT be any thicker than 2.5” (63.5mm).

6. Care must be taken by the paver installer so the mortar covers the Heating Cables
/ Mats and they will not make direct contact with the pavers. We recommend that
at least 1.5” (38mm) thick mortar is poured over the Heating Cables / Mats, but no
more than 2”(51mm).

80% of the circuit capacity. 7b. Should you feel no warmth from the surface that the system is installed within 60 minutes,

verify that there is power to the control or thermostat. Contact WarmlyYours after verifying that there is power to the system.

Under no circumstances should you or anyone else tamper with or attempt to repair the snow melt or slab heating system

- this will render the warranty null and void. 7c. Switch the system on and off as you would any conventional electric heater,

although timers or thermostats may be used if preferred. 7d. Use reasonable care in the operation of the system. Do not

drop heavy articles, pierce or cut the surface that the heating system is installed. 7e. All restrictions and warnings detailed

in the installation guide must be strictly followed.
