Do not operate heaters at voltages in excess of that stamped on the heater since excess voltage will shorten heater life. 2. Do not operate under conditions that result in temperatures higher than the recommended maximum, since excess temperatures can cause premature heater failure. The maximum recommended temperature on sheath materials normally supplied is: Stainless Steel — 1200°F Alloy — 1600°F 3. Electrical terminals should be protected from spillage of plastics, water, oil and their vapors which can create electrical hazards and/or heater failure. 4. Do not energize heater in free air or at more than rated voltage. 5. Stud heaters are generally used in large banks to allow uniform tightening of...
