of air through the finned element, dust will
collect between the fins. The heater should
be cleaned regu-
larly for maximum efficiency.
3. To clean heating element fins, first remove both wiring com-
partment covers and the front cover. Using avacuum cleaner
or compressed air, remove the dust and lint from the alu-
minum heating element fins while being careful not to dam-
age the fins.
