Warnings and cautions Risks of electrical shocks and fire For safe installation and efficient performance of this system, read the instruction manual thoroughly and keep it handy. • Where applicable, installation must meet requirements of the following codes: - Canadian Electrical Code (CSA C22.1 Part 1); - National Electrical Code (NFPA 70);... -
Page 5: Product Specifications And Details
Product specifications and details The floor heating system is designed exclusively for interior floor heating. The system is not designed for snow melting or any other outdoor uses; it is mainly designed to complement a building’s primary heating source by serving as a secondary (floor warming) or primary room heat source (radiant floor heating);... -
Page 6: Selection Of Floor Heating System
Selection of floor heating system Selection of floor heating system will depend on the application. As a general guideline, we recommend installation at a maximum of 12 watts per Sq.ft. for heating and comfort applications. Depending on the claimed result, the cable system can also be used in 9 watts per Sq.ft. applications. To ensure optimal heating results, please contact a qualifed individual. -
Page 7: Critical Information
Critical information 1 Heating cable must not touch, crossover or overlap itself at any point. (Please use strapping to avoid bunching or crossover of cable). This could cause the cable to overheat. 2 Heating cable cannot be cut. 3 The heating cable length cannot be altered in any circumstances. This may cause over heating resulting in damage to the cable. - Page 8 24 Required distances and clearances NEVER install a heating cable under an interior wall or any fixed unit, a closet or in any other location where air cannot circulate freely over CAUTION! the floor surface. Always maintain the following minimum clearance: • Minimum 3" (76 mm) between heating cables;...

Page 9: Selection Of Floor Covering Material
Selection of floor covering material The type and thickness of floor covering materials used with this product must not exceed a thermal insulation “R” value of 1 (RSI = 0.123). Thermal resistance Typical floor covering Vinyl tiles 0.20 0.035 Linoleum 0.22 0.039 Ceramic... -
Page 10: Thermal Insulation
Thermal insulation The insulation levels of a floor will affect both the performance & running costs of floor heating system. The thermal insulation reflects the heat upwards into the floor tile instead of allowing heat to penetrate into the subfloor and keeps the floor warmer for longer time. While installing the floor heating system, user should install adequate thermal insulation below it. -
Page 11: Installation Instructions
Installation instructions Once you have chosen the area to be heated, measure the area in sq.feet (do not include the area taken up by fixed objects such as appliances/baths/kitchen units, etc.) and required watt density for your room. Now calculate total required output by multiplying area x watt density required for the room. Choose nearest suitable wattage cable from the available range. When calculated size required is between two sizes of offered cables, select the smallest of the two. -
Page 12: Room Layout And Corresponding Floor Heating System Product
7.2 Room layout and corresponding floor heating system product • Create a room layout plan to scale (for maximum accuracy, use the manufacturer form designed for this purpose); • Identify all stationary elements (toilet, bath, shower, counters, drawers, and permanent furnishings) and never install the heating cable under these stationary elements (Figure 1); • Determine thermostat or temperature control location; • Note room dimensions; • Determine the electric cable (cold lead) location that will be connected to the heating control; • Calculate the heating area in square meters (sq.m.) [square feet (sq.ft.)]; Sonde de température Figure 1 Liaison froide Need help to optimize your work plan?

7.4 Marking the floor Figure 4 • On the floor of an empty room (under construction or major renovations), draw the location of stationary elements (toilet, bath, shower, counters, drawers, permanent furnishings) that will be installed later. These marks will outline the heating area to ensure the heating cable system is not placed under these stationary elements;... -

- Page 17 Installation of the heating cable • Set the cable near the connection box and regularly lace the heating wire respecting the distance between the sections; 76 mm (3”) minimum; • Do not bend the cable at 90° when setting it in the strapping hooks; leave a 25 mm (1“) radius. This radius comes naturally; the cable must not be forced to have a tight bend; • A tag is located at 50% of the cable length. During installation of the product, verify the cable half tag to compare with your cable layout planification. Adjust pattern with the result to cover the surface. If the cable is too long, use the buffer zone to spend the remaining cable.

7.6 Installing the temperature sensor temperature sensor channel Figure 9 Hot glue gun, hammer, wood chisel or concrete chisel • To minimize floor height, chisel a 10 mm x 10 mm x 250 mm (3/8” x 3/8” x 10”) channel in the subfloor to receive the floor sensor. The junction has an insulation sheath and a slightly larger diameter than the heating cable. The sensor must be embedded in cement or an equivalent binder IMPORTANT! (cement glue, ceramic glue, self-levelling cement). -

See Section 5; • Completely embed the heating cable in self-levelling cement (Figure 10). It is crucial that the ENTIRE heating cable be embedded. No part of the heating cable must be exposed. (A small part [top] of the heating cable may be exposed at the surface of the self-levelling cement ONLY IF a ceramic glue is used... -

Page 21: Measuring Resistance And Measures Table
7.9 Measuring resistance and measures table • The master electrician who installed and connected the floor heating system must complete the measures’ table (this label is available at the opening of the product) and give it to the customer. This sheet must be kept near the electrical service. If this table is not duly completed, the warranty may be annulled. CAUTION! Warranty terms are at the back of the front cover. -
Page 22: Temperature Controller
Floor sensor & temperature controller Important The floor heating system must be controlled by a temperature control system. If the floor heating system is to be used for floor warming, an electronic floor temperature control featuring a floor sensor is recommended to ensure heat levels never exceed the floor covering’s maximum temperature tolerance. The room temperature control and floor temperature sensor must never be installed where they will be exposed to sunlight or air drafts. -
Page 23: Pre-Installation Preparations
Pre-installation preparations 9.1 Installation tips • For multilayer wood flooring (engineered floor) or linoleum, it is recommended that you consult the manufac- turer to verify whether these floor coverings are compatible with a floor heating system; • Fasten the cold lead and floor sensor to a concrete subfloor with adhesive (hot glue, tape). 9.2 Floor Covering tips • It is strongly recommended to coat the subfloor with a sealer before spreading the self-levelling cement (which is very liquid). This is to prevent any leaks under the floor; • The use of a latex primer on a concrete subfloor is recommended to ensure the self-levelling cement adheres better to the concrete;... -
Page 24: Operating Tips
Operating tips 1 When first energized, the heating cables may take sometime to fully warm your floor. 2 Energy consumption will vary depending on user preferences. 3 Energy consumption can be minimized by turning the system OFF when floor heat is not required, but you will have to allow time for the floor to warm up once the system is turned ON again. 4 Avoid placing thick mats/rugs/floor level furniture/mattresses on your heated floor. These restrict the transfer of heat away from the cables and result in the floor area beneath them being warmer than other areas. - Page 25 Checking for breaks The ohm resistance of each cable should be measured. Make sure the probes of the ohmmeter do not touch the earth wire at either of the line wire. Make sure you do not touch either of the probe ends, or the meter will be reading your internal body resistance.
