#1 - On the outside of the 4014 where is the inlets for the oil burner?
#2 - On a car we have an air cleaner with a filter. Is there a filter system for the oil burners to keep out dust & dirt?
No Big Boy expert, but on most oil burners, the burner itself is positioned at the front of the fire box, between the frames. You normally wouldn't easily be able to see it.
No, no filters are used. In fact, on an oil burner, great quantities of sand are deposited into the firebox in order to scour the tubes and flues of soot!
