Rodger thank you for that. We are off on a 5 day Bristol Rally starting tomorrow morning . Brother Geoff is a member of the UK club so should have the article.
A bit of a look at the heater today made me realize how complex the system is, It would appear that there are at least 3 flaps inside the box one of which is activated by the heat knob which also turns on the hot water tap.
As you said the 411 has the flow through fresh air vents as well. I may yet have to pull it out and apart to work it out,which i suspect cont be an easy job.
