Is this vent pipe installed incorrectly and the source of my prob
I have discovered a very high level of moisture in my attic and as a result the insulation a near the gable end is very damp and i now have mold all in my attic.
I suspect that the Furnace vent that was installed on the lower attic/roof which is placed approximately 15inches away from the gable wall/siding of the 2nd story attic is the source of the moisture/mold.
I have witnessed hot steam/humid air venting out of this pipe and due to its proximity of the upper attic and siding I suspect this is how the moisture is coming in. I have gone out there on dry days and the siding was dripping water like it had just rained.
As you can see form the attached photos the vent is placed very close. The second photo is from the inside of the upper attic on the opposite side of that wall. You can see the wall itself is very damp and the insulation in that area is a different color/damp.
Can anyone tell me if
1. They believe this is in deed the source of moisture and not poor attic venting? I only moisture build up on this gable wall and the insulation elsewhere is dry.
2. Is this vent placement against code? I am not an HVAK installer just a common home owner but I have done several searches and found references to NFPA 54 stating ""..so that the flue gases are directed toward brickwork, siding, or otherconstruction, in such a manner thatmay cause damage from heat orcondensate from the flue gases"
3. if this was installed incorrectly is the company that did the work legally liable for correcting the problem and fixing the damage caused? I used a very large company and had ever permit pulled and passed inspection by the city.
