95% Furnace in Garage
Hey guys so I called alpine home air products, the salesman suggested I buy a high efficient furnace so I can just run the intake and exhaust air pipes right out the side of the garage instead of up through the ceiling. From the unit to the wall is 16'. 1/4" per foot raise would be a 4" drop from the ceiling for the unit to hang. My question is can I run 2 45 elbows straight to the ceiling and have the remaining length (12'-+) flush against the ceiling. Or do the pipes need to have a consistent raise the whole length? Thanks Evan

Water condences in the exhaust pipe, so it needs a drop.

The unit needs to be lower or the pipes? From what I understand from the sales rep is you have the unit lower and there's a drain on the inducer motor.
