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.

I did not make any changes. The gooseneck picture is one I found online (I know it looks just like my house siding color). My manual says 12" distance so that is why I am writing on this forum to see if anyone can answer if the gooseneck would work or would I need them to cut another hole in the house and move the pipe over 12 inches?

How would the installer check alternative venting options? I don't see anything in manual.

Also what would happen if the exhaust ever did recirculate...would carbon monoxide and other gases spread throughout the house or would it just get sent back out the exhaust but shorten the life of the unit? As you can see I have no idea about any of this stuff...but it sounds scary. The installer obviously did not read the book and I want to make sure its done correct. If I don't need to have another hole in my house if the gooseneck would accomplish same thing I would like to know from all of you experts on here...much appreciated!

Right now I have about 20 ft of pipe and 3 elbows. I am not good at this but that would give me around 35 ft at most. So if I had them add a 12" gooseneck to the end outside that would give add on around 11 more feet correct?

So that makes it less than 50 feet and book says I can have up to 90.

Kdean1 - I looked at the manual and there is actually a diagram specific to my unit which says min 8" from center to center of 2 pipes and max 36". If I measure center to center its now 5" so still off by 3". What would you do? A Gooseneck? It still isn't correct and if it was inspected would have failed even though its only 3".

I am referring to the city inspector when a permit is pulled. My main goal is as you say is to prevent recirculation and the installer did not follow the manufacturer manual for proper spacing. We are having other issues and I came across this when looking through manual - I always thought they looked too close but didnt think much about it initially. I want it fixed when they come back out in a few days. The exhaust has a coupling on the end of it it so didn't know if a quick fix would be just to add 8-12" pvc pipe extension onto it. That way it blows it out farther away from house and the intake pipe. By adding gooseneck it brings it up closer to windows even though they are obviously closed when heat is on and pipes aren't directly below them anyways

What is the proper spacing near windows or does it not really matter?
