Separation of Air and Exhaust-

So, it looks like I shouldn't separate the air intake and my exhaust vent more than 15" because of "pressure zones" issues. I wanted to dump the concentric and pick up my air from around the corner, maybe 12 feet away, 4 feet lower, in the eaves. Lochinvar says I could do this if I exhaust thru the roof, but not the sidewall. Doesn't make any sense to me, can anyone explain?

On an earlier....
thread we discussed concentric venting and cross contamination. (some call it reversion)
I think this is a bigger problem than some think...including myself.
They do want you to keep the vents on the same side...just a good separation AND at different levels.
Around corners you can get more pressure drops than if running up a chimney and just a draft. Imagine getting a wind sucking air out the intake at the same time the boiler is trying to exhaust.0
