Veria Flexicable 10 Twin Conductor Underfloor Heating Cable, 300W, 28m, Nordic

• Low installation height:  Veria Flexicable 10 has a continuous effect of 10 W/metre, which, combined with its low installation height of just 4 mm, makes the Veria Flexicable 10 the ideal choice when renovating an existing floor. The cable can be installed directly on the substrate. The easiest way to affix it is by using VeriaFix double-sided tape or similar, although it can also be secured using a glue gun.
• Top-notch safety: The heating cable is equipped with a fully protective aluminium screen, which is connected to the earth connection of your electrical installation. Should the cable break unexpectedly, the built-in screen connection will immediately shut down the system - without any risk to people or animals.
• Select the correct output: The area that a given cable can cover depends on the desired output per square metre, and thus on which c-c distance cables are installed with it. The recommended output depends in part on the room's insulation, and partly on the floor's surface and substrate materials.

Features:

• 4 mm installation height
• 10 W per meter
• Can be laid directly on a combustible subfloor
• Aluminium screen (100% shielded)
• CE marked in accordance with EN 60335-1 and 60335-2-96

Installation Guide:

1 Let’s get started:

• A. Necessary tools: Hammer, chisel, pencil, tape measure, craft knife, multimeter, insulation tester and this guidance leaflet and plan.
• B. Plan: Draw your room on graph paper (fig. 2). Remember to draw in any fixed furniture/cupboards etc. and the location of your thermostat/power supply. The heating cable should not be installed beneath items fixed to the floor, such as cupboards, bathtubs, toilets etc. Based on your preferred output (W/m²), the net floor area and the cable length, you can now calculate the required C-C distance.
• C. Transfer your plan with its markings onto the floor, so that you know exactly where you will start and finish.

2 Test your Veria Flexicable:

• Before you lay the heating cable you must check whether the conductor cable works properly. The resistance value is measured using the multimeter between the blue and black sections (fig. 4a). Check that the value measured matches the value on the label between the heating cable and the power cable. The value displayed must lie within -5% - +10% of the given ohmic value. Make a note of the value measured on the proof of warranty.
• Then measure the insulation value with an insulation tester. Measure between the screen (outer connector wiring) and both the black and blue sections (fig. 4b). The measured value must be over 10 MΩ. In positive case tick the field on the proof of warranty.

3 Fitting:

• Fitting on a concrete floor or existing tile floor (fig. 5)

• Start by cutting/drilling a groove in the wall and floor from the connection point. A separate tube for the thermostat’s floor sensor and the heating cable power cable is fitted into this groove (fig. 5). Make sure that the groove for the floor sensor stretches at least 50 cm out into the room and that the sensor is placed between two heating cables. The curve of the tube must have a radius of no less than 6 cm (fig. 5).
• Before you fit the cable you must prepare the floor surface. Make sure that loose items and sharp edges are removed and that the floor is vacuum-cleaned or washed (fig. 6). To secure the cable in position while casting layout a double adhesive tape onto the floor. The adhesive tape should be laid perpendicular to your proposed cable layout spaced evenly every 50 cm (fig. 7). The cable is now ready to be laid out according to your layout plan. If extra securing is needed you can fit tape on top of the cables along with the tape lanes (fig. 7). Continue laying the heating cable until the total floor area is covered. Any excess heating cable must be reconfigured into the floor area by adjusting the C-C distance between the cables. Ensure all heating cables are evenly spaced across the floor area. Note that the yellow cable under no circumstances can be cut or shortened!
• When all of the cables are installed correctly test the resistance value in the cable again (fig. 4a-4b). Use the same procedure as in section 2 – then make a note of the values on the proof of warranty. Feed the power cable (black) back to the thermostat connection point and cover the heating cable with a layer of screed or similar (fig. 9). If the top flooring tiles the heating cables must be covered with min, 3 mm flexible screed, self-levelling compound or the like. If the top flooring is wooden floor, carpets, etc. the heating cables must be covered with min. 8 mm flexible screed, self-levelling compound or the like.
• Please note that the connection joint between the yellow and black cable must be cast into the concrete or screed. Take care not to step o nor damage the cable when laying out the heating cable and casting the floor

4 Final tests:

• After casting, measure the resistance value in the cable again (fig. 4a-4b). Use the same procedure as in section 2 – then make a note of the values on the proof of warranty. It is recommended that the concrete, self-levelling screed etc. be left to harden in accordance with the manufacturer’s instructions before the top flooring of tiles, wood, laminate etc. is laid (Fig 10)

5 Finishing:

• After the work has been completed the floor must harden completely before the floor heating and thermostat are connected. This process usually takes 8-10 days, but you should refer to the filler manufacturer’s guidelines. To connect the thermostat, please refer to the thermostat installation guidelines. The Veria Flexicable must be supplied through a residual current device (RCD) having a rated residual operating current not exceeding 30 mA.

Specifics:

• Veria Flexicable 10 is a 2-conductor underfloor heating cable that can be used for both primary and secondary heating.
• Depending on your floor construction you are free to choose the output level you need to fulfil your heating requirements. Please follow the guidelines below.
• The area that a certain cable length covers depends on which output you need, and consequently which centre-to-centre (C-C) distance the cable installation requires
• Note that the heating cable must be connected to the power supply by an authorised electrician.

Guidelines for selecting the right output:

• For concrete floors with carpet, laminate, vinyl, parquet or wooden top flooring max. 60-100W/m² is recommended
• For concrete floors with tiles on top max. 150W/m² is recommended

Veria Flexicable can be used with the following thermostats:

• Veria Control B35/45
• Veria Control T45
• Veria Control W35/45
