I am building a new, two-story home and plan to have a separate furnace on each level. The top floor has a space in the attic for a furnace and the contractor has cut a hole in the roof directly above the furnace location. From there extends a white plastic pipe with a cone shaped tip that extends up about 18 inches. This is seen at the tip of the roof above the front door and from the street. It detracts from the appearance of the house where it is currently located.
The second furnace in the basement has a vent pipe extending straight to the rear ground level wall and the contractor placed a vent outlet right next to the rear patio doors which is also quite noticeable where it is located.
The contractor tells me that these are the most direct routes for these vents and the vents cannot be configured to bend in different directions. I would much prefer the vents to be moved to the rear roof area in the case of the attic furnace or the side of the house with the basement located unit.
We plan to use 92% efficient Trane or Carrier variable 2 speed furnaces. How much flexibility is there in vent locations for these and can vents be directed in 90 degree bends without significant problems?
Thanks very much for any suggestions or advice!
