Installing Noritz 931 and read the first vertical run cannot exceed 3'..if you add a horizontal section and then go vertical again that ok.
Any reason for this...does too much vertical venting cause suffocation of unit?

Most likely for condensate, high efficiency gas units leave a lot of water behind in the exhaust.
Put in a vertical condensate tee and all will be well.
Makes sense the condensate accumulation is not something noritz or anyone else wants running back to unit.
thanks for the posts
