This picture is from the same house as this other post. Can you see how the furnace flue has come apart? This is actually from the second furnace in the attic, not the same one as before. Which means that BOTH furnaces were spewing CO into the attic space. I thank God that no one died as a result. These furnaces had been in place for 2 years, and the homeowner was totally unaware of this condition. She was greatly alarmed when she saw this, as you can imagine.
