The venting instructions for my furnace say the vent has to be 4' from a window that may open, but only 1' from a permanently closed window. I don't have more than 8' between windows, so that is a serious problem. Can put a screw in though a double hung window to make it a permanently closed window?

I don't understand that part ^ I think the reason for the min distance from a window is so exhaust won't get sucked into the house. Therefore how far is the vent from the nearest window? About screwing the window shut, that is probably a question for your local inspector, and if that will suffice, my guess is no.

If it is siliconed permanently shut that usually is allowed. A screw is too easy to remove after the inspector leaves, just to pass inspection so silicone is a better bet. Should check with them 1st. __________________ "Cut it twice and it is still too short". To view links or images in signatures your post count must be 10 or greater. You currently have 0 posts.
