Flue pipe angle

Nitwit

I got a good deal on this Goodman furnace for 25.00. It was built in 2005 and it is a 45000 BTU single stage. I did a temp hook up in the garage and it worked fine.
I want to add this furnace to the basement for extra heat during entertaining etc.
My question is being that there is an inducer motor can the angle of the flue pipe be less than what was required on the older furnaces?

Nope.
1/4" per foot.
