Installation with an Uncoupling Membrane

All heating cable, including the connection connecting the heating cable to the non-heating cable must be installed in the membrane and covered with thinnest cement;
The cable must not be installed under furniture attached to the floor where air cannot circulate: toilet, washbasin, vanity, wardrobe, bath, shower, etc.;
The cable should never be installed in a wardrobe, wall, cabinet or ceiling;
The heating cable must never be installed over an expansion joint;
The minimum installation temperature is 5°C (40°F);
Approved spacings are: 2 and 3 alternate cone spacing; 3 cone spacing; 3 and 4 alternate cone spacing and 4 cone spacing. Alternately, 3 cone spacings is standard.
An independent grounded circuit must be installed for each heating cable.
The maximum straight length for a cable line is 12 ft. (3.6 m). Cable’s have to make a detour (U-shaped) around a membrane cone and every 12 feet thereafter. (See photo 1).

The cold joint between the heating and non-heating section of the cable system is bigger in diameter than the membrane slot. To make room, please cut off a piece of the membrane about 1 inch by 12 inch min. Lay the cold joint directly on the sub-floor, within the opening, and fix it with tape or hot glue. (See photo 2).

Buffer zones are places where it is not absolutely necessary to heat. Use these areas if you have a slight excess of cable.

If you are short of cable follow our technical information for the different scenarios of spacing. Note that the wider you space the cables, the less heat there will be. The standard spacing is at 3 cones in the membranes.

installing the cable

After carrying out the first cable resistance and insulation tests and confirming that the reading are good, (note: write the results in the Test Log Sheet) install the connection part of the cable (connecting the heating part to the black non-heating cable) in accordance with the instructions of the membrane manufacturer and run the non-heating cable through the wall to the thermostat. Start installing the cable in the membrane per instructions.

Installation with Plastic Cable Guides

IMPORTANT
Initial cable and sub-floor verification procedures are outlined on page 17 to page 20. Read and understand them carefully before installing. If you have any questions, please contact Warm All.

Installation with Plastic Cable Guides Instructions
Attach the cable guides to the subfloor, perpendicularly to the direction of the cables, with screws hot glue, staples, nails or double-sided adhesive tape.

3 inch spacing = 14.8W per sq.ft.
4 inch spacing = 11.2W per sq.ft.
5 inch spacing = 8.8W per sq.ft.
Optimum and/or standard spacing is 4 inches

The elaboration of a floor plan is essential before laying the cable on the floor.
This will help visualize the layout. All Warm All cables must be installed with a regular spacing of 3, 4 or 5 inches, 4 inches being the standard and are available in the 120V or 240V.

Define the area of the floor to be heated where there is no fixed furniture (such as a shower, toilet, cupboard or washbasin, etc.) and calculate the area to be heated.

Example of cable installation on the floor
Total area 96 sq. ft. minus 22 sq. ft. of fixed furniture space equal heated area 74 sq. ft.

Using the specifications and the calculation of the total area to be heated, you can choose the desired heated cable size. Define the optimal layout of the floor to be heated using the table below. Warm All (www.BuyWarmAll.com) to ensure adequate coverage. Choose a location to place the thermostat on a wall above the heated zone, where it can be reached by a 10 foot cold lead wire and the floor temperature sensor lead wire.
lt is recommended to leave a minimum of 3 inches between the wall and the first heating cable.

Cable installation
After performing the first resistance and insulation tests, confirm that the cable has no faults. Write the results in the Test Log sheet. Place the cable so that the connection point and the temperature probe are at the expected starting layout position.
Bring the power cable to the thermostat or junction box.
Begin the installation of the heating cable according to the layout developed using the templates approved.

IMPORTANT
Do not cut or shorten the cable. Do not expose it to mechanical stress. Avoid walking on the heating cable. Wear shoes with soft soles.

Cover the cable with cement / thinnest
Depending on the floor covering you have chosen (such as cement, ceramics, stone, engineered wood, laminate flooring, etc.), cover the heating cable system, including the floor sensor and heating cable connections to the cold lead with an appropriate thickness of cement to obtain a smooth and straight finish.

General Information
Warm All recommends that you consult the flooring manufacturer for specifications. Preparation and installation of the flooring must be carried out according to the manufacturer’s recommendations.

IMPORTANT
Perform the 3rd cable resistance & insulation test when the cables are covered with fresh cement.

The system must not be switched on until the cement / thin set is completely dry. A minimum of 4 weeks is recommended.

Installation on BC-Fir (Fir tree) plywood
Cement installation

Warm All recommends taking pictures all along or during the installation.

The thermostat can now be connected by following the manufacturer’s instructions. lt is recommended that a qualified professional exicutes the connection to ensure proper operation of the system.

Connection to the electrical network

You must write the appropriate information on the breaker in the electrical panel. Please identify with a label (Room ID, #) the selected breaker feeding the heating cable.

Perform a 4th cable resistance & insulation test. Write the results in the Test log Sheet.

Write the information in the Test Log sheet
it is important that the installer sends to Warm All the Test Log Sheet through mail, fax or e-mail immediately after the installation of the system (cable and thermostat). Failure to do so will void the Limited Warranties. Warm All will register your Warranty only upon receipt of these forms as well as purchase invoices as mentioned in the warranty information sheet.

Enjoy the comfort of your Warm All floor heating system.
The system is now ready for use.

Registration of all tests is mandatory
To obtain our Limited Warranty (25 years on the cable and 5 years on the thermostat) or our Comprehensive Limited Warranty (25 years on cable, 5 years on thermostat and 10 years on installation) you must perform these tests and record the results on the test log Sheet. You must perform all Cable & floor sensor tests.

Check cable integrity when to test?

When receiving the cable;
After laying the cable in the membrane or subfloor with our plastic cable guides and before covering the the cable with cement;
After covering the cable with cement and before laying the floor covering;
After the installation of the floor covering and before connecting the heating cable to the thermostat. Enter all test results on the warranty log.

Before removing the plastic that covers the cable on the spool, the cable insulation and resistance should be verified and compared to the factory values to ensure the cable is intact. Factory test data is on the grey tag at the end of the cold lead black cable. Results should be similar to the factory result. Please refer to it. If it is more than +/-10% difference, call Warm All.

You must perform the insulation Resistance Test, the Resistance Test, and the Sensor Resistance Test (the floor sensors, are in the thermostat & cable box) during the installation process.

Use an appropriate multimeter to measure the resistance between the 2 conductor 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. Write the result on the Test Log Sheet to register your Warranty. Please check that your measuring instrument is set properly calibrated.

Heating Cable lnsulation Resistance Test
This test ensures that the insulating jackets of the cable are not damaged. A low value indicates the cable has been damaged and must be replaced. Use a multimeter or a megohmmeter.

Connect the ground wire to the black lead of the tester and both load wires (heating cable) to the red lead of the multimeter or megger.
Make sure the meter reads “OPEN” or “OL” or ‘I’. If you get a different reading, contact Warm All at 1-855-396-5600.
Record these readings on the test log sheet to register your warranty.

For the Full Limited Warranty to be valid you must perform the insulation resistance test using a megohmmeter (megger). ln a two-step method, perform the above test at 500 volts DC and then at 1000 volts DC. Please record the readings on the Test Log Sheet.

Heating Cable insulation Resistance Test
This test measures the resistance of the Cable and is used to determine circuit integrity.

Set your multimeter to the 200 or 2000 ohms range (see image A).

On 120V, connect the multimeter leads to the black and the white cold lead wires. On 240V, connect the multimeter leads to the black and the red cold lead wires.

Compare this resistance reading to the resistance specified in the Product Selection or cable tag. The value should be within ±10%. If you get a different reading, contact Wrm All at 1-855-396-5600. Record these readings on the Test Log Sheet to register your warranty.

Sensor Resistance Test

This test measures the resistance of the floor sensor and is used to verify the sensor integrity.
Set your multimeter to the 200K ohm range. Connect the multimeter leads to the sensor lead wires.
Make sure the meter reads between 9-25K ohms. If you get a different reading, contact Warm All at 1-855-396-5600.
Record these readings on the Test Log Sheet to register your warranty.
