Item # HX-904U01750N, Sloped Top Architechtural Sill-Height Convector

The 906/904 Series architectural sill-height convectors are designed to fit under large windows to prevent cold down drafts. These heaters can provide total or supplemental heating for a variety of applications.
  • Installation Options : Units may be mounted to the wall flush on the floor or on pedestals. Custom lengths, blank sections and inside or outside corners are available for wall-to-wall installations. Units can be ordered with smooth finish when the back of the heater is visible. Heaters 200 watt/ft. or greater are not designed for residential use in the United States.
  • Added Safety :The sloped-top cabinet on the 904 Series prevents objects from being set on top of the heater, which can restrict airflow and cause overheating.
  • Choice of Colors : Heaters can be matched to any decor. White or almond is standard and a wide range of optional colors and custom finishes are available.
All models listed are single-phase.
