Hi
Assuming I have met requirements pertaining to Vent wall penetrations both around distances from functional windows, doors, property lines, distance above ground and no eaves/soffit vents - and aesthetically I am okay with idea of a wall penetration...what is the proper way to physically achieve? I assume some screen is a must, is a 2" vent 90 upside down satisfactory?

You must follow the I&O manual for what ever appliance you are considering venting. It will clearly define proper vent length, material and termination.

paul, i believe he is asking about a plumbing vent..
anyway, it is always best to consult the local inspector. codes vary all across the country. (and so do inspectors opinions)
if it were allowed around here, the vent stack would have to be brought up to a point 18-24 inches above the roof.
sometimes the stack is brought up to the roof overhang and using two 90's offset over and up. sometimes it goes up to the overhang and penetrates it.
in no case is it ever allowed to penetrate the wall and terminate, no matter what you do to the end. (up, down or sideways)

Not if he used a "direct vent" heater, and if he had gas.

I have a couple of these on my house, 1.5" PVC through the wall with a little screen tacked on the shingle.
House is 100 years old....previous owner fancied themselves a handy plumber, as a result the whole house needs to be re-piped, including getting rid of these vents and running everything up to a stack. Fortunately, the electric is in in good shape, either PO knew what he was doing or hired a sparky.

Through a 1 1/2" hole? Mega back pressure.
