FENIX LSDTS 8, 12 Cable Heating Mats Installation Guide

FENIX LSDTS 8, 12 Cable Heating Mats

CABEL HEATING MATS

• This product is only suitable for well insulated spaces or occasional use.
• Heating mats may be operated only as a part of building structures. Fixing the heating cable to the fiberglass fabric during manufacture by gluing is regarded to be only a temporary bond. The heating mat is intended for installation in wet construction processes (concrete, adhesive and “self-leveling” sealing materials based on cement fulfilling thermal flexibility requirements – during application it is necessary to follow the manufacturer’s instructions). When in use, the heating mat must be in full contact with these materials and free from air bubbles.
• The mat may be adjusted only as shown in pictures 1 – 3, and in no case may it be shortened. You may shorten only the cold connection ends, as required. The connection joining the cold end and the heating cable may not be installed in a bend, both cold cable and heating cable should be installed straight at least 5 cm from the end of the connection before any bending. The heating cables of the heating mats may neither touch nor cross one another. The minimum distance between the cables is 30 mm. If the heating or power supply cables are damaged, they must be replaced or repaired by the manufacturer, its service technician or a similar qualified person in order to prevent a dangerous situation from arising. Do not use nails or screws to install the cables!
• When installing the cables, the diameter of a bend in the cable must be at least eight times greater than the cable’s diameter.
• The heating cable must be supplied with electricity by means of a residual current circuit breaker with rated actuating cur-rent of IΔn≤30mA. We recommend that each heating unit/circuit be equipped with a separate residual current device.
• For safety reasons, heating mats may not be installed in walls.
• The heating mats may be stored at temperatures from +5°C to +35°C and installed at temperatures from +5°C. When in operation, they may not be exposed to temperatures exceeding 70°C.
• During removal from packaging, manipulation and installation of the mat take special care to avoid mechanical damage to the mat – check the heating cable visually before pouring the building material.
• The heating mat may not be installed on irregular surfaces
• The heating mat is primarily intended for installation with the supporting material facing the base.
• In case that mats are laid in an area larger than 20m2 or with a diagonal greater than 7m, it is necessary to account for expansion of the foundation materials. The heating cable must not cross the expansion joints. The non-heating connecting cables located at the expansion joints must be laid loosely in a protective tube. All installed elements – cold connection end, thermostat’s probe – where they pass from the wall to the floor must be placed in installation tubes and must allow for movement of the floor and wall relative to one another.
• To allow for expansion around the periphery of the room between the baseboards and the floor tiles, use an expansion profile or fill the spaces with silicone sealing cement.
• The distance between the heating mat and the wall must not be less than 50 mm.
• The mat must not be placed either under such furnishings as bathtubs, shower baths, toilets and the like or under furniture that does not allow air to circulate. The maximum thermal resistance between the heating part and the room may be R=0.15 m2K/W.
• The installation must allow for disconnecting the mat or mats at both poles. The minimum distance of disconnected contacts must be 3,5mm.
• The label on the cold end of the heating mat shows the serial number and production date. The label on the mat’s packaging shows type, dimensions and area of the mat, total output, output per 1m2, as well as the mat’s supply voltage and electrical resistance.
• Before and after laying the mats, it is necessary to measure the resistance of the heating circuit. The measured values should be equal. Record the measured values in the certificate of warranty.
• Before and after laying the cables, it is necessary to measure the insulation resistance between the heating conductor and the protective braiding. This measured value may not be less than 0.5MΩ. Record the measured values in the certificate of warranty.
• Before opening the package with the heating mat, it is necessary to check whether the data on the label is in accordance with your requested product.
• In case of any discrepancies, you should report these immediately to the manufacturer or supplier and discontinue the work completely.
• You must draw the scheme of the heating mat layout in the certificate of warranty, indicating the exact distance of the connections of the supply cable and heating part from the walls of the building. Record the serial number and production number of the heating mat that are stated on the label on the mat’s cold end, then insert/stick this label into the connection box.
• The supplier must inform other construction suppliers about the heating unit installed in the floor and of the related risks.
• A sheet of paper with information about the heating system must be permanently kept in the switch box of the heating system and passed on to any new owner or tenant.
• When installing the mats, the CSN 33-2000-7-753/HD 3844-7-753; EN 50559 standard requirements must be met.
• The product is produced according to the EN 60335-2-96/IEC 60335-2-96 standard and must be installed in accordance with the national regulations for electrical installation.
• The heating mat can be installed in the bathroom even under zone 0 under the condition that the connector and the end of the heating cable are installed outside this zone.
• If part of a heating mat extends under zone 0, the mat must be connected via a residual current device with a trip current of 10 mA.
• An insufficient thermal insulation layer below the heating system may cause significant thermal loss (warmth moving downwards). Recommended thermal insulation is 70–80mm of extruded polystyrene or similar thermal insulation materials. In case of reconstruction, where there is not space to install the thermal insulation to a sufficient depth on the existing tiles, we recommend installing F-boards in a depth of 6mm or 10mm to accelerate the warming of the surface and to reduce the thermal loss. This material is installed into the adhesive sealing cement that was shaped by a notched spreader and the heating mat is placed directly onto its surface. The F-boards do not need to be penetrated.
• The user must be instructed by the supplier regarding the installation of floor heating. This fact is stated on a label which comes with the product and must be glued into the switchboard: this label also informs readers that the making of openings is prohibited, as is covering the floor with furnishings or fittngs without leaving at least a 4 cm gap between the floor and the bottom surface.

Description and cennection

• The heating mat consists of the heating cable attached to a supporting fiberglass fabric.
• The heating cables should be connected to a 230 V, 50 Hz electrical network. Degree of protection: IP67.
• LSDTS mats have protective braiding. The cable’s protective braiding meets the standards required of metal grid or metal shield and provides increased protection in spaces where that is required (bathroom, laundry, etc.) The protective braiding is to be connected to the PE conductor or to a protective grounding connection.
• The entire bottom side of an LSDTS mat’s fabric is covered with a self-adhesive material allowing the mat to be attached to the foundation. The foundation’s surface must be free from dirt and foreign matter.
• The mats are wound on a paper tube, with the heating cable end protruding out of the supporting fabric. After unwinding the mat, affix this end to the fabric using the enclosed fastening strip (see picture).

Using mats for direct floor heating

Dimensioning

• If the floor heating is intended to be used to warm the floor surface for short intervals, we recommend that the heating mat be installed close to the floor’s surface.
• If the floor heating is to be used to heat a room, it is necessary to know the thermal loss value for the build- ing in order to select the most suitable heating system.
• The installed output should correspond toa multiple of 1.1 to 1.3 times the calculated thermal loss for the building. If it is impossible to install the calculated out put into the entire floor area, an additional heating device must be used (for example, direct heating con-vectors).
• For short-term heating and for bathrooms, we recom mend using the LSDTS 12 heating mats with output of 160W/m. For rooms occupied for long time periods, we recommend using the LSDTS 8 heating mats with output of 80 and 100W/m.

Installation – direct heating system

• First read Clause 1 of the General Terms and Conditions.
• To allow for expansion around the periphery of the room between the baseboards and the floor tiles, use an expansion profile or fill the spaces with silicone sealing cement.
• The distance between the heating mat and the wall must not be less than 50 mm.
• An insufficient thermal insulation layer below the heating system may cause significant thermal loss (warmth moving downwards). Recommended thermal insulation is 70-80mm of extruded polystyrene or simi reconstruction, where there is not space to install the thermal insulation to a sufficient depth on the existing tiles, we recommend installing F-boards in a depth of 6mm or 10mm to accelerate the warming of the surface and lar thermal insulation materials. In case of to reduce the thermal loss. This material is installed into the adhesive sealing cement that was shaped by a notched spreader and the heating mat is placed directly onto its surface. The F-boards do not need to be penetrated.
• Detailed descriptions of use for the individual materials can be found in the installation manuals for the recommended materials.

PROCEDURE

• Unroll the heating mat and adjust it according to the area to be heated. Mark the place for the connection and ending of the heating mat on the floor.
• Create pockets” in the base material where you wil place the connections for the heating and non-heating components.
• Clean the concrete area, remove any sharp objects and coat it using a suitable penetrating solution.
• Measure the resistance of the heating circuit and the insulation resistance and record the measured values in the certificate of warranty.
• Use flexible adhesive sealing cement and a flat spreader to smooth the floor surface (be careful not to damage the cable with the sharp edge of the spreader).
• Before laying the floor tiles, measure the heating circuit values again and record both values in the certificate of warranty.
• Lay the floor tiles onto the surface.
• When putting the heating mat into operation, the adhesive sealing cement must be fully hardened (see instruction for use and recommendation from material’s manufacturer).
