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


Fly ash adheres to and bites into vinyl siding real well.
