The head of the bed is directly over the boiler. The boiler
is direct-vented through the cellar wall. There are no windows
on the boiler end of the house. On windy nights, there is an
annoying noise that seems to come from somewhere in the
exhaust line. Sounds to me as if there is a gravity flapper in
the terminator or elsewhere that is moving back and forth. I
was puzzled because I thought the vent on most of these
systems was electrically controlled.
Could someone help diagnose this problem? Also
I'd like to know a little more about what moving parts
exist between the point of exhaust from the boiler and
Also, is there a cure?
(Note: This question is being asked on behalf of some
friends who recently bought a house that's about three
years old. At present, I do not have the boiler model,
but could obtain it if necessary.)
Thank you for your help.
P.S. The boiler is a Weil-McLain

The exhaust stack on my Utica oil boiler in the basement goes straight
up through a shaft in the center of my house and then out the roof. It
must be 25' long. The gravity balanced flapper is in the exhaust pipe
just above the boiler. When there are high winds blowing outside, my
flapper flaps. Not big flaps, but just enough to be able to be heard
when I am in the basement. I would suppose that a shorter exhaust pipe
would cause more vigorous flapping.
