Long sweep 45 degree elbows


My instructions for installing my new furnace calls for using long sweep 45 degree elbows if you need to align the combustion air or flue vents to avoid ceiling joists or to align with an existing opening. I cannot find such an animal I have searched the local stores and i have searched to internet and I do not find any manufacture listing such a product. Do any of you all know if these really exist or do I just use the standard dwv 45's.

Two 45* are equal to a 90*. If you use two 45s you'll be ok.

No such an animal as long sweep 45.

Yes I understand that 2 45's equal a ninety when counting bends in these plastic vent/flue systems. And they make long sweep 90's in DWV plastic but know one catalogs a long sweep 45 in DWV plastic there are long swwep 45's in metal. So I will just use the standard DWV 45's. Thanks for you all's input.
