The one's I have enciountered ar packed in tar, like
some NST's. These are older ones. Last time I had my
burner serviced, tech said:
I've never seen one that old.
To be exact, i have not studiedout the new burner: it may be
cycling the ignition, as others have noted. Older OBIT's ran
'continuously'. Both sorts did exist, at one time.
