Heating cable information
The heating cables consist of a fixed length of heating cable terminated at one end with
9’ of unheated lead. We recommend you do not alter the length of the unheated lead,
however if necessary, the wire can be extended if a UL-approved wire and connector box
suitable for the purpose is used (e.g. waterproof if going into the floor, etc.). This must be
carried out by a qualified electrician in accordance with local/state laws and guidelines.
Inspect the entire heating cable for damage, this includes the factory made joint and end
termination. The joint and end termination cannot be altered or remade if damaged. If
any parts are damaged contact the technical helpline (888-927-6333).
The core and ground braid are factory joined in a water resistant joint assembly to each
supply conductor and ground conductor of the unheated lead.
The Warmup Undertile™ Heating Cable is
