3. Points of attention
The MAGNUM Cable is insulated and watertight and can be installed on Foil finished insulation (Kingspan or Celotex) or existing concrete bases. The construction of the cable also allows installation in wet spaces. The heating cable may never be
MAGNUM Cable
installed under fixed objects like wall units, kitchen units, baths, or showers and must be able to give off its warmth unimpeded.
The power supply must be disconnected during installation. All installations must be wired through a suitably rated MCB or RCCD when applicable. All installations in wet areas must be wired through a dedicated RCCD in line with the thermostat. All connections must be made by an approved Electrician in accordance with current IEE regulations. The electrical heating cable is patented worldwide and fully conforms to the European IEC 800 standards.
The connector cable can be extended or shortened, there must always be at least 0.5 meter of connecting wire left. The heating cable cannot be shortened! The end seal cannot be broken.
If multiple cables are installed in a space, they must be wired in parallel and a suitably rated junction box may be incorporated so that only one power cable runs to the thermostat. Maximum capacity of the thermostat is 16 Amperes. If fitting more than one cable set and the combined area length exceeds 194 meters (3400 watts), a suitably rated Contactor will have to be fitted. The thermostat may only be installed by a qualified electrician.
Before installing the MAGNUM Cable, the resistance reading should be taken and noted down on the inspection card in the center of this manual. Keep this inspection card in the meter cupboard in a visible place this is part of your guarantee! (see point 8)
The sensor must always remain IN the sensor conduit. Fit cap to end of the sensor conduit. If the sensor ever needs to be replaced it can then easily be removed.
The MAGNUM Cable can be used under various floor finishes - Tile, Marble, Slate, Wood, Laminate, Vinyl and Carpet. (Tog rate of
carpet and underlay should not exceed 2.5). If using underneath a wooden floor or carpet please contact your flooring supplier.
4. Guarantee
Please visit www.magnumheating.com for your local guarantee conditions.
5. Necessary materials
Required for installation:
- Standard junction box (min 35mm deep, preferably 50mm) for the thermostat.
- Mounting material: Tie wraps, alu-tape, MAGNUM Spacerstrips or smooth Weld Mesh.
- Electrical conduit for the connecting cable for the thermostat.
- Flexible mortar or sand/cement screed (dependent on the mounting height).
6. Preparation
- Check that the cable length/wattage is correct for the area of free floor surface that must be heated.
- Check the available electrical connection and mains voltage in the space for installation.
- Test the cable with a multimeter and check with the test data in Section 2.
- 1 or 2 grooves must be cut/ground in the wall for electrical conduits, 1 for the power cable and 1 for the floor sensor. Do NOT run the power cable and sensor cable through the same pipe.
- Ensure that the base floor is clean and level.
- Always apply insulation to the base floor if possible. Uninsulated floors will have downward heatloss.
- Place expansion strips around the perimeter of the area (for coping with the contraction and expansion of the floor).
MAGNUM Cable
7. Sensor
Ensure that the sensor is installed well clear (min. 50 cm) of central heating pipes, water pipes, drains and electrical wiring. The sensor must be installed in the middle of a cable loop for optimal temperature registration. Ensure that the heating cables do not make direct contact with the conduit in which the floor sensor is mounted.
8. Resistance readings
Before installing the Comfort Cable, the resistance reading should be taken and noted down on the inspection card in the center of this manual. The reading should be taken during the installation and on final completion. These readings should be as per the technical information (Point 2). Take measurements both between the resistance wires and between the resistance wire and the earth cladding. Keep this inspection card in the meter cupboard in a visible place! This forms part of your guarantee.
9. Calculations for Heat Requirements
150+ Watts/m² for prime heating of normal rooms cable spacing 100 mm
100/125 Watt sq. m for comfort heating of normal rooms cable spacing 125/150 mm
Example: for a conservatory of 20 sq. m floor surface multiply the total floor surface with the above mentioned capacities (20 x 150 Watt = 3000 Watt) Choose set 3300 - 3300 watt. Cable can be sized (or checked) by measuring the linear length i.e. Heat required 150 watts/m². Room size 4mx3m =12m² Cable spacing = 100mm. Therefore 4mx30 = 120 linear mts. Use 2100 Watt set (124 linear mts).
If there is any excess cable left after installation, you can space a few runs at

50mm at the window & door areas of the room to lose it in the floor.
NEVER SHORTERN THE CABLE.
10. Fitting the cable to the floor
Feed the cable end (marked with *****) through the electrical pipe to the back box for the thermostat. The word "splice" must stay visible. Splice must be covered by screed. Fix the spacer strips at 500 - 600 mm centres with masonry or Hilti nails. Attach the cable in a zigzag fashion with a distance between the cable as required. If reinforcing is used (Smooth Weld mesh at 100mm square) plastic tie wraps can be used for attaching the cable directly to the reinforcing. Extend the 2nd electrical pipe to about 50 cm from the wall and have it end in the middle of a cable loop. Pull the sensor cable to the back box and ensure that the sensor is in the conduit. Ensure the cap is placed on the end of the conduit so that replacing the sensor is always possible. Please contact your local Technical Department www.magnumheating.com if you require assistance on the spacing of the cable.
11A. Applying the mortar directly to a concrete subfloor
-
Lay the spacer strips at 500 -600mm centres. Attach the cable at the desired/ specified spacing.
-
Ensure a good bond and by brushing the subfloor with cement powder or PVC glue.
-
Then apply a thin layer of sand/cement screed (5/6:1) of 3.5 to 5.0 cm. Allow it to cure before the tiles can be laid or other types of floor coverings applied.
-
This method of application is also suitable for applying pourable liquid screeds in

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.

an auxiliary heating source, however, by installing more capacity than it is no longer necessary to install a separate radiator and the MAGNUM Mat/ Cable can serve as the main source of heating. This allows more space for fixtures or furniture. The capacity must match the heating requirements / calculations for the space in question. Please check your local supplier via magnumheating.com for advice.
ALLOW THE FLOOR SUFFICIENT DRYING TIME: Consult the supplier/manufacturer regarding the applicable drying time for the product. For sand/cement screed floors a drying time of 1 week per applied cm with a minimum of 30 days is generally observed. Consult the supplier/manufacturer regarding the applicable drying time for your situation.
The position of the thermostat is determined in accordance with current local regulations USE OF THE THERMOSTAT Check the thermostats manual for correct programming.
SHORTENING/EXTENDING THE CONNECTING CABLE: The connector cable can be extended or shortened, there must always be at least 0.5 meter of connecting wire left. The heating cable cannot be shortened; the end seal cannot be broken. THEMOSTAT POSITION:
thicknesses of between 3 and at most 6 cm. 5. Protect the cables when bringing in the cement or grout by using duckboards. Never use wheelbarrows with unprotected footrests.
NB: For large spaces it is necessary to create or observe expansion joints in multiples of approx. 40/50 m2. The cables may not cross the expansion joints to avoid damaging the cables.
11B: Applied Directly on top of Insulation
When laying the Comfort cable onto the insulation the Comfort cable must be laid and secured onto a steel mesh. Do not install the cable directly onto the insulation. The cable is laid on to a smooth reinforcing mesh (approximately 100mm square), and secured with tie wraps. When using insulation, the top surface of the insulation must be aluminium covered and coated appropriately to resist reaction with screed. Kingspan and Celotex manufacture insulation boards for the sole purpose of underfloor heating. The Comfort cable must not come into contact with the insulation. Contact the insulation manufacturer for compatibility with cable floor heating systems and fitting instructions.
It is very important that the bedding is applied free of air bubbles. Air bubbles form insulating, non-conductive areas where the cable cannot release its heat and a danger of overheating arises which can cause damage to the cable.
To avoid this first of all wetter screed must initially be used to enclose the cable in the screed. Following this drier cement can be used for levelling the final bedding. In this case a pourable liquid screed is also a good option.
Protect the cables when bringing in the cement or grout by using duckboards. Never use wheelbarrows with unprotected footrests.
