I live in an old house that has a gravity furnace. Can you tell me what types of maintenance should be performed and how often this should be done?

I don't think there has been any maintenace done on this furnace in over 4 years. It has a clean out door which seems to be encased in ages of dirt.

Thanks so much for any info

Remove the access door and clean all dirt and debris. Fresh air is needed for combustion. Clean the cast-iron main burners. Check the flue pipe condition and for proper pitch. Check the draft on the chimney with a lit match. The flame should pull inward. A heater should be inspected at the beginning and end of each heating season.
