  • For models that have a set and sealed cutout stop, you cannot lower the temperature cutout stop. The control only responds to the lowest temperature along any 14 in. to 16 in. section of the entire 20 ft element.
  • All models feature a screwdriver slot range adjuster.
  • If a model does not include a mounting bracket, use the following brackets:
    • Standard mounting to a vertical surface: Part Number 271-350.
    • Mounting to a horizontal surface with an L bracket: Part Number 271-51.
