INSTALLATION GUIDE

This unit

complies with

CSA and UL

standards

Before installing and operating this product, the user and/or installer must read, understand and follow these instructions and

keep them handy for future reference.

If these instructions are not followed, the warranty will be considered null and void and the manufacturer deems no further responsibility for this product.

The following instructions must be adhered to in order to avoid personal injuries or property damages, serious injuries and potentially fatal electric shocks.

This product must be installed by a qualied person in accordance with this installation guide. All electric connections must be made by a qualied

electrician, according to the electrical (Canadian Electrical Code Part 1 or National Electrical Code) and building codes effective in your region.

This heating cable is designed for indoor embedded oor heating applications in which the heating section of the cable, including the cable connection joint,

are embedded in a mortar type layer or thin-set, under a oor covering.

Cut off power supply at circuit breaker/fuse before installation or reparation.

Minimum temperature for cable installation is 0°C.

NEVER CUT THE HEATING CABLE. This would change the cable resistance and could lead to a re.

WARNING The heating section of the cable must never touch or cross over itself. The minimum radius of curvature is 13 mm (1/2 inch). This cable must be grounded and connected to a ground fault circuit interrupter (GFCI). The GFCI must be a class A (5 mA) for a bathroom in Canada. In the U.S the GFCI must be a class A (5 mA) for a bathroom and kitchen.

VALIDATING YOUR FLOOR HEATING CABLE SELECTION AREA TO HEAT Before installing your new floor heating system, first make sure that you have made the right cable selection. Re-measure and recalculate the area that will accommodate the cables. Do not forget to exclude all areas that cannot be heated (cupboards, bathtub, etc.) as well as all areas that you do not want to heat.
PAGE 6
Plan the location of the thermal sensor between two cable runs, at a distance of at least 24 inches (60 cm) from the wall or centered between walls (see FIGURE 14). The sensor should be installed in an area where temperature reflects the overall temperature of the floor. Thus, it should not be located in areas likely to alter the temperature measurement, like an entrance door, an external heat source, under pieces of furniture or an area exposed to the sun.

TEST # 2: VALIDATION OF THE NON-CONTINUITY BETWEEN THE HEATING WIRE AND GROUND BRAID This test requires the use of a multimeter. TEST 2 - CONNECTIONS N.B. Since all measuring instruments are different, we recommend you to consult the non-continuity test section of your instrument user’s guide. The heating cable is protected by a ground braid. An electrical insulator prevents any contact between the braid and the two conductors.

GETTING STARTED SUBFLOOR PREPARATION PLYWOOD SUBFLOORING TIPS Self-leveling mortar If self-leveling mortar is used to cover the cables, all subfloor gaps must be filled to prevent liquid mortar leaks. You must choose waterproof plywood (BC fir). Before buying another type of plywood, you should call your concrete manufacturer. Surface preparation Plywood surface must be clean, solid and dry. Remove any dust, oil, grease, paint, wax, sealant or any other substance that could impede adequate adhesion.
PAGE 9
MOUNTING BRACKET SECURING METHODS N.B. In order to work efficiently with hot glue, the subfloor surface must be very clean to ensure adequate glue adhesion. The installation strappings must be installed in order to have the first pass of heating cable along a wall, and the cable loops near a wall, both at a 3 inch (76 mm) distance from it. The installation strappings must be mounted at a distance of 3 inches (76 mm) parallel from the wall with respect to the center of the loop of heating cable.

Using the factory splice as a starting point, secure the cable to the floor in accordance with the pre-established cable layout and the following standard spacing (based on the wattage/square foot selection).
PAGE 11
CONCRETE APPLICATION The heating cable must always be embedded in concrete or covered by a thin concrete layer. Two methods are available: SCRATCH COAT (method recommended by STELPRO) as well as THIN SET METHOD (alternative method for experienced tile setters only). Please refer to the CONCRETE SELECTOR TABLE on following page to find out the type of concrete recommended for each method.
PAGE 12
Installing floor coverings other than ceramic tiles onto the scratch coat Before installing any floor covering other than ceramic tiles onto the scratch coat, always consult your floor covering manufacturer to ensure product compatibility with floor heating system. N.B. Natural hardwood floor treatments are not compatible with floor heating system.
PAGE 13
FLOOR TRANSITION To install the heating cable between two horizontal floors please follow the following important notes: • The heating section of the cable must not pass through a wall and/or be installed inside a structure. • The minimum radius of curvature of the cable is 0.5 in. (13mm).
PAGE 14
OPERATING TIPS Do not place pieces of furniture, carpets or rugs over the thermostat sensor because it would compromise the efficiency of the floor heating system. The heat generated by the floor heating system may modify the latex, rubber or vinyl backing of some carpets. The backing may stain the floor covering or even stick to it. Thus it is not recommended as floor covering.
