DEFINITION

Classification: 392/347

Convection space heater:

(under subclass 200) Subject matter under Class 219, ... wherein air heated by an electric device is intended to heat an occupied space, e.g., a room by the motion in a fluid resulting from a difference in density and the action of gravity.
