I have a gas furnace. I recently discovered that the manual says the intake and exhaust pipes should be 12" distance between each other but the installer only has 3" (picture attached). I want them to fix it so it is as it should be. I also would like to avoid another hole in the side of my house if possible. I came across this picture and was wondering if this would accomplish the same thing. Instead of putting the side by side distance 12" they added a gooseneck to the exhaust pipe so it is 12" vertical. Wouldn't that accomplish the same thing? Any help/advice would be appreciated.
