proper ventilation for furnace?
Need some help here. I am in the midst of remodelling my bathroom, and have noticed how poorly vented my furnace is. The only name or print on the furnace is HW SV-9500. The house is single story, 1600 sq ft. ranch. The furnace is in a small closet with a small hole to the crawl space, and a 10″ or so duct in the ceiling up to the roof.
The flue coming out of the furnace is 4″. It goes up a foot or so to an adjustable elbow that is merely offsets it a few inches. It continues up from there for 5 feet at which point it is poorly connected through the floor to a six inch adjustable elbow that connects to another 3 feet or so of 6″ duct that goes through the roof.
All of the duct is single wall galv. no firestop. There are no supports either.
My plan is to replace all of the vent pipe, the 4″ & 6″, with a run of all 4″ double wall flue pipe, add a firestop at the floor, and support the pipe. Is this a good idea?
Do I need the 6″ duct from the ceiiling up? The installation is so poor it leads me to believe the installers had no clue what they were doing. I won’t get into how none of the supply ducts are sealed.
thanks.
