Re: smoke and co detectors

["Total nerd" <geekboy0001@xxxxxxxxx>]

Robert's account sounds spot on.  I have seen this happen twice -- once
in my house and once in a friend's house.  In my house, the fireplace
drew so much updraft that the furnace chimney backpuffed.  The newly
installed windows and doors made the home so airtight that the most
effective way for the fireplace to draw it's needed air was back
through the fireplace chimney, causing a backpuff and the CO detector
to go off.  Cracking a window open during fireplace operation fixes
this, of course.  Secondly, I witnessed a friend's home backup CO and
smoke from the furnace while having a birthday party.  The attic fan
was going full-tilt and all the windows and doors were closed.  That
fan, as powerful as it was, pulled enough air to choke the furnace and
fill the basement with smoke and fumes, causing an alarm.  My wife
actually "smelled something funny" and thought that it "felt just like
the problem we had," then waddya know, it happened to them minutes
later.

I recommend a Rate-Of-Rise heat detector in the garage, not a smoke or
CO detector.
