Important

· Read the instructions carefully before installing Heat Cable system.

· Remember to measure the resistance four times.

· Do not install Heat Cable in walls or ceilings.

· The cable must be embedded in mortar, thinset, concrete or similar material.

· The minimum installation temperature is 40℉(5℃).

· The heating cable cannot be cut to length, crossed over itself, or installed too close.

· It is recommended to use copper wire only.

· Remember to check that the supply voltage matches the voltage of the Heat Cable.

· Remember to place the labels as written in this instruction.

· Only for indoor installation.

· Metal structures or materials used for the support of or on which the Heat Cable is installed must be

grounded in accordance with CSA Standard C22.1, section 10 and the NEC.

Please consult the factory for any other questions or advice.

3 Floor Heating Design and Product Selection

3.1 Design the Installation

Step 1: Measure the heated area

Determine the heated area of the floor where there are no permanent fixtures or furniture such as showers,

toilets, vanities, or cabinets. Measure the heated area of the floor.

For example, in Figure 3, the area of the bathroom is 96 ft

. When you subtract the area of the vanity, shower

and toilet, the total heated area is only 74 ft

Step 2: Determine the power supply voltage

The available supply voltages include 120 V, 208 V or 240 V.

Important

Operating the 240V cable at 208V reduces the power output to approximately 2.25W/ft. (25% reduction)

Step 3: Plan the design

Determine the optimum floor heating Cable layout for your heated area to ensure coverage. Select a spot for

the thermostat in the wall above the heated area where it can be reached by the 10-foot cold lead on the Heat

Cable, and the 10-foot floor temperature sensor. Please refer to Figure 4.

Important

The predetermined Heat Cable spacing must be maintained to ensure proper floor heating. Do not change the

heating cable spacing when you lay out the cable or the floor may have cold spots.
