I had access to a ladder the other day, so naturally I was poking around in the attic of our house where we have lived for about a year. Above the closet where the furnace and water heater are located, I found there was a metal flue that didn't extend all the way through the roof, it just stops in the attic. Is this normal? There was a flue right next to it that did extend through the roof. The house was built in 1999 and we haven't had any problems since living here. I looked in the furnace room closet and couldn't see anything that might be connected to it. The building inspector didn't mention anything about it when we bought the house. Here's some photos:
So, what do you think? Will our house burn down, or will we die of carbon monoxide poisoning?
