The Heatwave Heating Cable comes in pre-established lengths that have been
designed to deliver a specified heat density. Therefore, it is essential that all of
the Heatwave Heating Element contained in your kit be installed.
In order to minimize the risk of damage to the Heatwave Heating Cable, Heatizon
Systems recommends that the Heatwave Cable be installed immediately prior to
the installation of the cementitious material that goes over it.
Never cross the Heatwave Heating Cable over itself, the in-floor sensor wire , or
any other conductive material or wire.
When installing Heatizon Systems products, strict compliance with the National
Electrical Code, local Building Codes, and Heatizon’s Installation Manual is es-
sential.
It is highly recommend to take photographs of the installed Heatwave before in-
stalling the flooring.

General Information
The instructions in this manual must be followed when preparing and
installing the Heatwave Cable or Mat Floor Warming System. This
manual and the installation layout should be made available to all
contractors and installers working on the job. Both should then be
turned over to the building owner after the installation is complete.
NOTE: FAILURE TO FOLLOW THE INSTRUCTIONS IN THIS MANUAL MAY VOID
THE WARRANTY ON THE FLOOR-WARMING SYSTEM.
Temperature and Time Control
For optimal control of the Heatwave floor warming system, contact your Heatizon Systems
distributor for a variety of floor-sensing thermostat options.
Maintenance
The Heatwave floor-warming system has no moving parts and is virtually maintenance-free.
The GFCI (Ground Fault Circuit Interrupt), internal to the thermostat if Heatizon Systems
supplied it, should be tested monthly as described in the manufacturer’s pamphlet to insure
its continued safe operation. If an external GFCI is utilized instead, it should be tested
monthly.
Subfloors
Heatwave may be installed over any well insulated subfloor (i.e. plywood, concrete, or underlayment material) prepared in accordance with the most recent TCA (Tile Council of
America) guidelines and rated to withstand 180 degrees Fahrenheit.
Floor Coverings
Heatwave will be most effective if installed under rigid floors that are naturally good conductors of heat such as ceramic tile, marble, and other stone floorings. There are limitations in
applications that utilize different floor coverings. Please consult with your Heatizon Systems
Distributor for details on heating wall-to-wall carpeting, parquet, laminate or engineered
wood floors and vinyl or linoleum flooring
Insulation
Heatwave will be most effective and efficient if installed over well-insulated areas. Insulation
will minimize heat loss into the subfloor (i.e. concrete slab), al-
lowing the heat to transfer to the surface more quickly.
4
Planning the Installation
Before laying the Heatwave Cable or Mat Floor Warming System, review the installation layout and verify that all dimensions match the need of the project. The installa-
tion plan should include the following:
1. Placement, direction, and dimensions of the Heatwave Cable or Mat
2. The starting and ending points of each Heating Cable length or Mat size
3. The location of the thermostat or other suitable activation
4. The location of the floor sensor between two heating cables
REMEMBER! The installation plan for each area should be attached to this manual
and be provided to the building owner when the installation is complete.

3 Floor Heating Installation Design
3.1 Design the Installation
3.1.1 Measure the heated area
Determine the heated area of the floor where there are no permanent fixtures or furniture
such as showers, toilets, vanities, or cabinets. Measure the heated area of the floor.
For example, in Figure 3, the area of the bathroom is 96 ft2, but when you subtract the area
of the vanity, shower and toilet, the total heated area is only 74 ft
3.1.2 Determine the power supply voltage
The available supply voltages include 120 V, 208 V or 240 V.
Important
Operating the 240V cable at 208V reduces the power output to approximately 9W/
sq.ft. (25% reduction)
3.1.3 Plan the design
Determine the optimum Heatwave Cable or Mat layout for your heated area to ensure coverage. Select a spot for the thermostat in the wall above the heated area where it can be
reached by the 10-foot cold lead on the Heatwave, and the length of the floor temperature
sensor. Please refer to Figure 4.
Important
The predetermined Heatwave spacing must be maintained to ensure proper floor
heating. To avoid cold areas on the floor, do not change the Heatwave heating cable
spacing when you lay out the Mat or Cable.

5 Installation
Important: Tools and materials required
The following items may be required to install and test the floor heating system:
Scissors Tape measure
Utility knife Screwdriver
Wire strippers Multimeter
Heatizon Plastic Cable Clips or Spacing Band
5.1 Before Laying the Heatwave Mat or Cable
Note: A continuous continuity check should be conducted on the Heatwave Heating
Cable or Mat and all electrically conductive material prior to and during the pouring of
concrete, installation of floor coverings, and immediately prior to energizing all Heatwave products. The circuit should always be open. Always complete a Heatizon Systems “Resistance in OHMS Form” (see form in the back of this manual) out of the box,
immediately following the installation of the Heatwave Heating Cable/Mat, immediately
prior to covering the Heatwave Heating Cable/Mat, and again just prior to energizing
the Heatwave Heating Cable/Mat.
Follow these steps to ensure a successful
Heatwave installation.
5.1.1 PLAN YOUR LAYOUT
Using the last page of this manual, make a sketch layout or
a floor plan of the room; include all permanent furnishings
such as toilets, bathtubs, appliances, cabinetry, etc. Indicate all dimensions required to determine the available
floor area and the position of the thermostat.
Important Heatizon recommends that the installation is documented with photos and drawings to note
the location of connections and the sensor.
5.1.2 TRANSFER LAYOUT TO FLOOR
Draw an outline of the layout on the room floor including a
foot print of all furnishings that are not yet installed. Unroll
the first few feet of the Heatwave Mat or Cable. The starting point of the cable must be placed within 10 ft. of the
thermostat.
Important Mark the position of the connection point
between the power lead and the red Heatwave heat-
ing cable. This connection must be concealed in ce-
mentitous material. When using a floor temperature sensing thermostat, mark the sensor position in the middle of
two heating cables, about 10 in. (25 cm) away from the
wall (within the heated area), as close as possible to the
thermostat.
12
5.1.3 INSTALL SENSOR
If using a floor temperature sensing thermostat,
install the sensor now, either in conduit tube, or
directly to the subfloor. The sensor and/or tube
needs to be installed between the thermostat wall
box and the sensor position. The conduit tube
must be partially countersunk into the subfloor. Cut
a channel approximately 5/16″ deep × 5/16″ wide
in the floor and wall up to the thermostat for the
sensor conduit. The conduit has to go from the
thermostat and minimum of 10″ away from the wall
towards the middle of the floor.
Note:It is recommended that the sensor be installed in conduit tube. This will allow the sensor to
be easily replaced in the unlikely event of failure.
Important
The sensor conduit must be centered in the cable loop (between two red heating wires). Use
duct tape to close the end of the conduit so that the cementitious material can't penetrate the
conduit. Use duct tape to hold the sensor conduit into the groove to prevent it from floating up
when the cementitious material is poured. If the sensor is installed directly in the mortar bed,
use duct tape to secure to subfloor.
5.1.4 PREPARE SUBFLOOR SURFACE
Clean and vacuum the floor thoroughly and remove
dust and debris from the floor that may damage the
heating cable. Ensure that the subfloor is secure
and stable. Carefully fill in all cracks to prevent any
potential damage to the new tiles resulting from
shifts in the subfloor.
5.1.5 MEASURE THE RESISTANCE (TEST #1)
Use a digital OHM meter to measure the resistance of the Heatwave Mat/Cable
and compare it to the total OHMS in table in Section 4.1 for Mats or in Section 4.2
for Cables. Record the measured resistance on the Registration Form. Documenting the resistance at each stage of installation is required for warranty purposes.
Also, measure the resistance between each conductor and the shielding/ground
wire. Both should read infinity. Please refer to “7 Commissioning” for instructions
on how to measure the resistance.
NEVER CUT OR SHORTEN THE RED HEATING CABLE!
DO NOT STAPLE THE RED HEATWAVE HEATING CABLE. STAPLE ONLY
THE WEBBING ON HEATWAVE MATS WHERE NO CABLE IS LOCATED!
NEVER PLACE RED CABLE WITHIN 6” OF A WAX TOILET RING.
13
If you are installing
HEATWAVE MATS,
continue with your installation
below beginning with section 5.2.
5.2 Heatwave Mat Installation
5.2.1 Start by placing the mat such that the con-
nection point and the temperature sensor are in
their intended positions and bring the power cable
to the thermostat or connection box. Begin unrolling the Heatwave Mat evenly across the floor
outside the areas that you marked previously.
When you reach the next wall, cut the mesh
(being careful not to cut the heating cable),
turn the mat, and begin rolling in the desired di-
rection.
5.2.2 Ensure that the Heatwave is in full contact
with the subfloor at all times. Avoid walking on the
heating mat. If this is not possible, use shoes with
very soft rubber soles. When approaching obstacles (toilets, cabinets, etc.), carefully remove
some of the red heating cable from the mat and
lead the cable around the obstacle. In some cas-
es pieces of the mesh will be cut away entirely.
5.2.3 Use Heatizon Plastic Cable Clips or a thin
strip of tape to secure the loose cable to the floor.
OR
If you are installing
HEATWAVE CABLES,
skip to Section 5.3 to continue
with your installation.
5.2.4 MEASURE THE RESISTANCE (TEST #2)
Use a digital OHM meter to measure the resistance of the Heatwave Mat and compare it to
the total OHMS in table in Section 4.1. Record the
measured resistance on the Registration Form.
Documenting the resistance at each stage of installation is required for warranty purposes. Also,
measure the resistance between each conductor and the shielding/ground wire. Both
should read infinity. Please refer to “7 Commissioning” for instructions on how to meas-
ure the resistance.
GO TO STEP 6.
14
If you are using Heatwave Cable, continue your installation
beginning with 5.3 below.
5.3 Heatwave Cable Installation
Make sure you have verified that you
have purchased the correct Heatwave
Cable to heat the area you have selected and that you have determined the
correct spacing for the area you are
heating, the Watts you need the system to deliver, and the size of system you purchased See
Table in Section 4.2.
5.3.1 Plan room layout using tape measure, marking
pencil, and chalk line. Lay out perimeter of area to be
heated first, keeping a minimum of 3 inches from walls
and or cabinets and the first run of element. Once the
layout is complete, roll out the Heatwave Heating Cable,
making sure that both ends of the heating element
(where the Heatwave Heating Cable is pre-connected to
the Cold Lead segment) are within 10 vertical and horizontal feet of the power switching thermostat location to
accommodate Cold Lead length.
Note: All of the Heatwave Heating Cable and the connection
between it and Cold Lead must be surrounded by cementitious
material.
5.3.2 Tie off one Cold Lead at the location where the
Power Switching Thermostat will be located. Continue by
laying out Heatwave Heating Cable on the predetermined
layout, and fasten with plastic clips as described below
for your floor surface.
5.3.3 When anchoring the Heatwave Heating Cable to
wood subfloors use either the Plastic Clips and Nails
Heatizon Part #ANCHPLUGKIT or Metal Spacing Banding Heatizon Part #HWCSTRAP33. Never use any attachment that will compromise the Heatwave Heating Cable or its insulation in any way. Each 90 degree bend
and each 180 degree turn requires two Heatizon Plastic
Clips. Heatizon Plastic Clips should be spaced approximately every 24 inches along the length of the Heating
cable. Heatizon Plastic Clips can be inserted around
Heatwave Heating Cable, and secured to sub floor by
hammering nail or driving a screw through anchor ends
until both plastic tails are flat against sub floor surface.
Repeat with each Heatizon Plastic Clip until all clips are
secure. If Heatizon’s Metal Spacing Bands are used
please check continuity between the Heatwave Heating
Cable and the Band as the cable is installed.
15
5.3.4 If Heatwave Heating Cable is being installed directly on existing concrete, a Heatizon Anchoring Plug Kit may be purchased.
Use a 1/4" cement drill bit to drill holes 1" deep in every location
where a nail or screw will be located. Install one Anchoring Plug into
each pre-drilled hole by tapping plugs until they are flush with the
surface of the concrete. Anchoring Plugs should fit tightly in pre-drilled holes. If using
Heatizon Plastic Clips, put a clip around Heatwave Heating Cable and secure by hammering nail through anchor ends directly into the wood plug, until both plastic tails of
the clip are flat against the concrete and plug. Repeat with each Heatizon Plastic Clip
until all clips are secure.
5.3.5 Continue laying out and anchoring Heatwave Heating Cable until complete.
Make certain the end of the Cold Leads attached to the Heatwave Heating Cable return to the thermostat location. When all of the Heatwave Heating Cable has been installed and secured, run the second Cold Lead parallel to the first Cold Lead back to
the thermostat, and secure both Cold Leads to the stud nearest the chosen location for
the thermostat.
5.3.6 MEASURE THE RESISTANCE (TEST #2)
Use a digital OHM meter to measure the resistance of the Heatwave Mat/Cable and compare it to the total OHMS in table in section 4.1 for Mats or in section 4.2 for Cables. Record
the measured resistance on the Registration Form. Documenting the resistance at each
stage of installation is required for warranty purposes. Also, measure the resistance between each conductor and the shielding/ground wire. Both should read infinity. Please refer
to “7 Commissioning” for instructions on how to measure the resistance.
6 Completing Installation
ENSURE THAT THE SENSOR CONDUIT HAS BEEN
PROPERLY INSTALLED BEFORE PROCEEDING
In the case of tiles, proceed with the installation of the tiles
by covering the heating cables with a layer of thin-set ce-
ment as directed by the tile manufacturer. Ensure that the
thin-set mortar covers the entire height of the heating cable
as the tiles are installed. In the case of a wood, engineered
or laminate floor covering, it is recommended that the flooring manufacturer be
contacted. For wooden floors, a minimum of 3/16 in. of self-leveling cement over
the heating cable is recommended. Ensure that all moisture in the self-leveling
cement has been fully eliminated in accordance with the drying times recommended by the manufacturer (consult the manufacturer for exact drying time) prior
to energizing your Heatwave product. Do not use Heatwave to dry self-leveling or
other cementitious material.
Important
The system must not be turned on until the cementitious material has fully dried.
A minimum of two weeks is recommended.

6.1 MEASURE THE RESISTANCE (TEST #3)
Use a digital OHM meter to measure the resistance of the Heatwave
Mat/Cable and compare it to the total OHMS in table in section 4.1 for
Mats or in section 4.2 for Cables. Record the measured resistance on the
Registration Form. Documenting the resistance at each stage of installation is
required for warranty purposes. Also, measure the resistance between each
conductor and the shielding/ground wire. Both should read infinity. Please re-
fer to “7 Commissioning” for instructions on how to measure the resistance.
6.2 INSTALL THE LOW RESISTANCE FLOOR COVERING
To install tile, apply a layer of acrylic or latex modified thin-set using the ridged
side of your trowel. Tile and grout the floor using best industry practices and in
accordance with instructions provided by the manufacturer of the tile.
6.3 CONNECT POWER SUPPLY AND THERMOSTAT
The connection of the power supply and the thermostat must be done by a
qualified person in accordance with the National Electrical Code (NEC) and
the Canadian Electrical Code (CEC). Connect the floor sensor to the thermostat, take the final resistance reading and record it on the Registration Form,

Note: You need to mark the appropriate circuit breaker reference label indicating which branch circuit supplies the circuits to those electric space heating
cables.
6.4 MEASURE THE RESISTANCE (TEST #4)
Use a digital OHM meter to measure the resistance of the Heatwave Mat/
Cable and compare it to the total OHMS in table in section 4.1 for Mats or in
section 4.2 for Cables. Record the measured resistance on the Registration
Form. Documenting the resistance at each stage of installation is required for
warranty purposes. Also, measure the resistance between each conductor and
the shielding/ground wire. Both should read infinity. Please refer to “7 Com-
missioning” for instructions on how to measure the resistance.
6.5 RECORD INFORMATION AND AFFIX LABELS
It is important for the homebuilder/owner to mail in the warranty certificate immediately after installing the system (Heatwave Mat or Cable and Thermostat).
Failure to do so could void the manufacturer's warranty. The warranty is subject to the guarantee conditions listed on the warranty certificate. Keep a copy
of the Registration Form for your reference. Place the included label “Electric
Shock or Fire Hazard” on the inside of the electrical power distribution panel.
6.6 ENJOY THE COMFORT OF HEATWAVE
The Heatwave Heating System is now ready to use. Increase the floor temperature gradually and adjust it until it reaches a comfortable level depending on
the type of room and your personal preferences.
