Is there a min distance from roof-shell angle to a nozzle?

[KernOily]

Guys is there some requirement as to a minimum distance to locate a roof nozzle from the OD of the nozzle to the roof-shell interface, or to the roof angle? I have scrutinized my 650 and I can't find it anywhere.


Thanks!

I do not recall seeing anything in API-650 about that.
