Ok I am installing a stainless steel chimney and wanted to get your opinions on what this hearth installer told me when I called for an estimate. I have a 2 story house. I am installing a stainless chimney out the basement wall and up. I thought I would have to go through the eves, as that would put the chimney straight up after the tee section. The chimney installer tells me that its better to avoid the roof and dealing with cutting holes and flashing and that he would instead use a 45 to go out from under the eve and up from there thus avoiding the eve. I was under the impression that its not good to have any other bends other than the tee 90 in your chimney. I told this to the installer and he said its not a problem because of the amount of pipe in between my tee and the 45 offset being about 20 ft. He said draft would be fine. Is he correct and is there anything else I should be worried about with having this 45?
