Hello all, I am a contractor and building manager. One of the buildings we manage that was rehabbed 10 years ago has a unit that is dripping water where the vent pipe is attached to the inducer housing via the rubber coupler. This water has dripped down and cause rust below. What is odd is that the induction fan has no water in it and the drain is open however there is a questionable connection at the bottom of the run that appears to be a T to a hose for the humidifier. It was noisy but that was due to the grommets being worn and the fan blower rubbing on the housing.
It is a Bryant 340aavo48100 left vented up flow setup. (unit can be up or down and horizontal) and on inspection I noticed a few things that I thought to be odd.
The fresh air intake housing has a coupler that has the fresh air intake attached to one side and the other is open. It is not capped. The Manuel says that this should be capped and should have a drain. What is the impact of this not being capped. I would think that less than optimal fresh air is making its way into the combustion chamber.
The next thing that I see is that if the vent is less than 8' there should be a 12" horizonal section to eliminate condensation. There is not. The vent leaves the housing horizonal outside the cabinet by a connection of 8" to and elbow and straight up through the roof. I have no measured it yet but its going to be less than 8' I am sure.
Not sure what the impact of these issues are on safety efficiency and longevity or why it could be condensing and dripping where it is and wanted to get feedback from the Por's here. I read all the time but never post so thank you in advance.
