NJinspector Posted February 22, 2009 Report Share Posted February 22, 2009 Ran into this today, wasn't that cold out, maybe 40. I understand that the water vapor turns back into condensation, but this seems a bit excessive, no? Click to Enlarge 41.58 KB Quote Link to comment Share on other sites More sharing options...
Rob Amaral Posted February 22, 2009 Report Share Posted February 22, 2009 Looks like an exhaust leak at the fitting. Knock off the ice, re-inspect, use a mirror while system is running. Try to isolate the terminus from that spot with a clipboard or something and hold the mirror near that joint. If you see mist, it's an exhaust leak. "Fix it". Could be leaking behind the siding, no?

SWagar Posted February 22, 2009 Report Share Posted February 22, 2009 I'd also check to make sure that there is sufficient slope to the exhaust flue (pipe) so that the condensate flows back toward the furnace. At the furnace there should me a means to get rid of all the condensate. However, if the furnace flue runs a very short distance to the exterior, the flue gasses may not have time to fully condense in the flue. In that case, they would condense outside. Judging by the location of the flue, I'm guessing that the furnace is in the basement. So the condensdate should go to a pump, sink, or floor drain. I just had a new Condensing Furnace (AKA High Efficiency, 90+ )installed, I'll have to say ,I'm amazed by the amount of condensate it produces.
