How to avoid it and fix it?
This message appears when the branch piping is more than +/ - 5 deg from being normal to the header pipe (i.e. 90 deg).
More explicitly, if the branch piping angle to the header pipe is over 95 deg or less than 85 deg, the message will appear.
To avoid having this message displayed, angle of branch piping to header pipe must be >85 deg but < 95 deg.
