Heating Mat Installation

Using a permanent marker, mark out areas on the subfloor where units and fixtures will be

fitted. Do NOT install the mat in any of these areas. Mark the position of any turns or cuts that

you will need to make on the floor.

Mark the positions and planned route of the power lead cables as well as the floor sensor. It

is best to avoid placing the floor sensor in areas of heat fluctuations. It may be necessary to

cut a channel in the floor to ensure the floor sensor is kept at the same height as the heating

element.

Start by laying a mat in the location closest to the thermo-

stat. The mats should be installed a minimum of 3” away

from the wall. Warmup recommends placing the mat with

the element facing the subfloor.

Roll out the mat following your floor plan. Cut and turn the

mat where marks have been made.

Be careful and never cut the heating cable.

NOTE: If you have a loose wire (wire cut away from the fi-

berglass mesh) make sure the loose wires are no closer than

2” from each other, the wall or from any other wires still at-

tached to the mesh. All joints need to be placed on the floor

beneath the tiles. No cables may cross at any time (including

the floor sensor and power lead).

Secure the mat to the subfloor using the double sided tape

on the mat. Use tape to fix any loose laid wires.

Route the power lead(s) from the floor to the connection

box. When using multiple mats, route all power leads in par-

allel, from the floor to the electrical box in the wall. To en-

sure the power lead remains at the same level as the heating

element, you may need to cut or chisel a channel in the sub-

floor. When doing this take care not to damage the heating

element. Secure the power lead in place using tape.

Ensure there are no loose sections, paying close attention to

the ends of the mats and any section which has been turned.
