There was an excellent article a little while ago in the BOC Journal which described the rather complicated (clever) workings of a 408(?) heater. Do you have access to back issues of the same?

The 411/12 heater is, I understand, from the viewpoint of a 410 owner, basically similar, with some clever fresh air variants, but trying to explain its workings and the clever variants feels rather too much after a glass or two, so let me know the answer to the above and I'll have some idea where to start from.
