I live in Northern Minnesota and 282 feet off of Lake Mille Lacs (big lake) on 3 sides SO, the wind can get real bad
from the North and Northwest primarily but can come from the South and East (kinda rare but does happen.) I don't have much for wind breaks and would take years for trees to grow tall enough to help.
I live in a Manufactured triple wide home where the exhaust vent is "roof terminated," and can not be moved without great destruction. The vent limit switch tripped once and was replaced but service guy suspected wind and I agree as it was 50mph and gusts to 80mph at times.
SO...he recommended that I install a pvc elbow and point it to the east...I did and it helped however winter came and now I'm knocking down little pointy glaciers from the dripping condensation coming out of the vent. Can't tell you how dangerous it is to be out in -14 weather let alone finding a good spot to plant your extension ladder so it's stable
The vent resembles a candy cane top so the dripping is straight down to the shingles and builds it's way back up to the opening of the pipe...I haven't let it go so I do not know if it would in fact grow up far enough to actually block the vent but I didn't want to take the risk and lose my very necessary heat.
I gotta come up with something that will block the wind, YET allow the condensation go back down the vent and allow the pump to shoot it down the drain. I'm thinking of cutting a pipe in half lengthwise and somehow securing it so that it will shield only the wind from the N, NW and yet leave the pipe open and able to vent.
I'm looking for any advise you have, I've looked at "high wind vent caps," but I'm concerned that they will freeze up and clog on me? I'll await your responses and greatly appreciate your expertise and time, thanks.
