4.2 Mat Placement
Roll out the heating mat in the desired area. The mat features an adhesive backing for initial positioning. The mesh can be cut to shape the mat around obstacles or to make turns, but never cut the heating cable itself. Ensure the mat is not placed under permanent fixtures. Maintain at least 6 inches of clearance from toilet gaskets.
