I ran into an Amana 90% Furnace yesterday (model # GUC090B35C / Serial Number 9101105998). The basement has been finished out fully, and is divided into a big family room with full doors to the upstairs.
There is a closet on 1 side of the family room with louvred doors out to the family room (closet room is about 7’ x 7’). On the opposite side of the family room is a kids bedroom. To get to the bedroom you have to go thru the family room (about 20’ x 20’). The kids bedroom only has 1 entry - thru the familyroom.
There is only 1 pvc pipe leaving the furnace / It goes out the roof and terminates with a “U-Shaped” elbow on the roof end. I don’t see a pipe in a pipe at the roof vent BUT I don’t see intake opening into furnace below.
I’m trying to find installation instruction on this unit and have had no luck.
Feel its totally wrong installation and improper C/A, but looking for info to see how its allowed to be vented.
