Steps 2 and 3 – Mark the floor for element position  Calculate in square metres the actual size of the area to be heated. Then, using the sizing/calculation guide on pages 6 and 10, establish the actual element spacings. ...
Page 13 Installation Step 4 and 5 – Lay out heating element and secure with fixing tape. Once the floor has been marked up, the element wire can be laid out.  Gently unroll the power supply cable from the spool. After 3 metres of black cable has been removed, you will reach the point at which the power supply cable joins the heating element wire (which is of a different colour).
Page 14  When you have completed about 90% of the element layout, gently unroll the remaining wire and the second power supply cable (black) from the spool. At the end point where the power supply cable meets the heating element you will find another join. Tape this join to the end point (which is the second chiselled channel), at least 50mm apart from the start point join that you taped down...
Page 15 This is quite acceptable provided that: a. The element is spaced at least 50mm apart at all times. Not closer. b. The element should never cross over. c. Never allow the heating element to be within the wall cavity, the black ‘power supply leads’...
