Called to swap out boiler with same size.  Found direct replacement. It was an easy swap all valves were in the right places.  Start up went well.  Call this morning no heat.  Returned to fined roll out switch out?  I have not found a reason for this yet but quiet sure it is going to happen again.  This is my question and concern.  I think the Z-Vent piping my be the trouble. There is condensate dripping in burner area. I can here it and see it.  Do I need to install a condensate tee?  The pipe is over 10 feet but not by much, Under 15  The other thing is the termination tee is on an upward 45 deg angle.  Not horizontal?  I did not change the any vent piping.
