†Heaters with Temperature Ranges 200-550°F are not UL listed.
Caution: Explosion resistant type E2 construction refers to heater design features which provide explosion resisting containment of electrical
wiring according to National Electric Code. Abnormal application or use of heaters which results in excessive temperatures can create
hazardous conditions which can lead to fire
Consult Section Z for data on allowable watt densities for more viscous materials.
