Product Information
The Warmup heating mat consists of a twin conductor resistance-heating element woven onto
a fiberglass mat. The heating element is insulated with Fluoropolymer (FP) with high dielectric
strength and high temperature properties. The conductors are covered by a metallic sheath pro-
viding additional mechanical strength and a ground path. A final outer jacket of Fluoropolymer
is given to make it sturdier and provide corrosion protection.
The heating cable is terminated at one end with a 10’ cold lead. The conductor cores and ground
braid are factory joined in a water resistant joint assembly to each supply conductor and ground
conductor of the unheated lead. The heater is terminated at the other end with a smaller water
resistant joint.
We recommend you do not alter the length of the unheated lead, however if necessary, the
wire can be extended using a suitable UL-approved wire and connector box. This must be car-
ried 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. If any parts are damaged contact the technical helpline.
The Warmup Heating Mat is approved (File No. E303230).
