How to Install

Step 1

Make sure that your sub-floor is clean and dry. Lay down the provided fixing strips on two opposite sides of the room. It may be necessary to install strips in the middle of the room to secure the cables. Secure the fixing strips with glue, screws, nails or staples.

Step 2

The cable can be secured around the strips at the desired spacing (between 3 or 4 inches) so that all the cable is evenly spaced. Remember, you cannot cut or shorten the cable at any stage.

Step 3

Secure factory joint to the subfloor and route the lead wire through the conduit into the thermostat box. In a separate conduit, bring the sensor down to the floor and position in the heated area. Finally, test the heating wires with an Ohmmeter for continuity and note the resistance on the Warranty Registration form.

Step 4

Apply thinset or self-leveling cement over the cables, about 1/4” thick. Work cautiously when using a metal trowel to avoid cable damage or movement. Let the scratch coat dry fully (a few hours to overnight) before flooring installation.
