unvented discharge

[MATT-]

Hey if an unvented cylinder discharge is discharged onto a metal roof, so capable of taking the water and 3 meters from any guttering, is the pipe to be elbowed down on to the roof of not and just left sticking out on to the roof?

With the maximum run of 22mm pipe from the tundish being 9 meters and each elbow or bend classes as 0.8 meters. Does a 45 degree bend class the same as an elbow adding 0.8 meters of resistance on to the run?

Can someone be standing/working where the water will discharge? If yes then it needs to be positioned to discharge safely to protect them
