Contractors onsite now. Rheem Prestige 90 unit is being installed within 5 feet of outside wall but outside 2nd story deck is about 7feet high. Contractors concerned about proper outside vending. May have to cut hole in deck & put in an elbow and vent it through the deck. I'm ok with this, but I am concerned if there are issues with 'how many elbows' or 'angle of elbows' or length of outside vent. Any advice would be GREATLY appreciated.
