TSI Series Fan-Forced Toe-Space Heater

The TSI heater is designed for installation in places where other heaters do not fit. These heaters can be installed into the toe space or kick space below a cabinet, in the soffit above a cabinet or into risers of a stairway.

  • Multiple Wattage: Quick disconnect lead wires allow output conversion from 1,000 to 500 watts.
  • Overtemperature Protection: Automatic reset thermal cutout is provided for primary overtemperature protection. More convenient than thermal fuses, which require field replacement when overtemperature conditions occur.
  • Two-piece Construction: Unit is designed for easy installation. The fan, motor and controls are factory assembled into a sheet metal box with a removable front grille.
