T&P valve termination

[inspect4u]

On the last two inspections, I have found the T&P valve drain line coming straight out of the home. I know they can't have a threaded end, but I seem to remember reading somewhere that have to be elbowed down at the termination, but I can't find any reference for that now. Has anyone else heard of this?
