Common questions about manuals, registration, and support for this brand.
No, you must never cut the heating cable. The system is designed to operate at a specific resistance. If the cable is too long for the primary area, you must use designated buffer zones (low traffic areas like behind doors or toilets) to accommodate the excess.
The Green Cable Surface XL is compatible with plywood, smooth concrete, cement board, and uncoupling membranes. It can be installed in dry or wet environments, such as showers, provided local electrical standards are met.
You should test the cable's resistance and insulation integrity at three stages: before breaking the seal on the spool, after securing the cable to the floor, and after the flooring is installed. Use a multimeter for resistance and a megohmmeter (1000V) for insulation testing.
FLEXTHERM typically offers a 20-year or 25-year limited warranty on heating cables and mats. A limited lifetime warranty may apply if the system is installed by a certified FLEXpert installer. Always check the specific product manual for details.
Yes, FLEXTHERM systems are best controlled by electronic thermostats designed for floor heating, such as the FLEXTHERM CONCERTO Connect. These thermostats often include a Ground Fault Circuit Interrupter (GFCI) for safety.
