      \n
    1. \n

      1)\u00a0The heater is less than 6 in (150 mm) in overall depth, the ratio of the overall length to the overall height is more than two to one, and the heater can be installed completely within a space of 18 in (460 mm) above the floor; or<\/p>\n<\/li>\n

    2. \n

      2)\u00a0The heater enclosure is intended to be connected to other heater enclosures to form a system.<\/p>\n<\/li>\n

      b)\u00a0Portable \u2013 A portable heater is identified as a baseboard heater if, excluding projections of guard or feet, it is less than 5 in (130 mm) in depth and if the ratio of its overall length to its height without the handle is as follows:<\/p>\n

      \n

      \n<\/p>\n<\/p>\n

      \n

      Maximum height of heater, feet (mm)<\/p>\n<\/p>\n

      \n

      Ratio of length to height<\/p>\n<\/p>\n<\/p>\n<\/p>\n

      \n

      2 (610)<\/p>\n<\/p>\n

      \n

    5. \n

      Exception: A portable radiant heater which has a visible glowing heating element and which is not sold or recommended for use as a baseboard heater may be excluded as a baseboard heater even if it meets the dimensional specifications in (b) above. Such a heater may be judged under the requirements for movable air heaters in the Standard for Movable and Wall- or Ceiling-Hung Electric Room Heaters, UL 1278<\/b>. For this determination, a radiant heater is one in which the visible portion of the heating element attains a temperature of at least 650\u00b0C (1200\u00b0F) under normal conditions of operation.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
