So the question i have is, can i just use a 45* or just run the vent straight out? the vent comes horizontally out of the house, the problem i am having is the selkirk cap i have shoots the exhaust out the sides kinda like a tee almost and it is turning my house black in a hurry. I have 2 ft out from the house so that's not the issue, i have a 45 left over would it be ok to just use that? btw the wind does not blow at that side of the house so that wouldn't concern me
