Heater Box Riser Tube - Correct Mounting?

Post by BusBassist » Thu May 16, 2019 7:56 pm

Now that the warm weather is here, I'm in the final stages of replacing the missing heat system components on my bus. The final piece to install is the left-side heat control box and its corresponding heat riser tube. My question is - does the heat riser tube flange fit 'between' the two engine tins as seen here:

OR is it mounted 'above' the upper engine tin as seen here:

It seems that it should be mounted above the tin instead of in-between. If in-between, there would be a small gap betwixt the upper and lower tins - causing some loss of air from the cooling fan. I consulted the Bently and did not see any photos that helped answer my question.

Any help would be appreciated.

Thank You,
