Because of the convection heating principle which depends on air
circulation through the finned element, dust will collect between
the fins. The heater should be cleaned regularly for maximum
efficiency. Before cleaning be sure the heater is off and the ele-
ment is cool. A vacuum cleaner with a brush attachment may be
used for cleaning. The finish of the heater may be cleaned with a
slightly damp rag if desired.
