Generator exhaust pipe extensions

[Brassman]

The length of the column of gas is a weight and that could increase back pressure regardless of stack diameter. That being said, a natural draft boiler needs a tall stack to draw draft to burn fuel.

Ours go from 1-1/2" pipe coming out of the Genny to an open air suction area on the bottom of the pipe and then up the 3 inch pipe above the roof on only 6 inches. It works well and never even with wind does it come into the coach even with bathroom vent going. We don't drive with it on but do run the genny sometimes for AC in the summer with no stack up.

Although our generator exhausts out the side of the bus, according to out CO sensor, we have never had a problem.  The radiator cooling fan is just above it, so any gas that rises is being blown away. We do have an extension for it to use when we are near other RV's.  We don't want to be blowing the exhaust at them.  We have a three inch diameter rubber shop exhaust hose that slips over the exhaust pipe at one end, and hangs with a hook to the rain gutter by the roof.

Hi All, George Myers article, "power plant poisoning", doesn't seem to take into account our own roof top fantastic fan vents. I raise the question, would any breeze, or no breeze gather the exhaust smoke into our own coach, if the exhaust extension from the generator was only two feet above the roof? lvmci...

WOW Tom.  Where did you read such a fascinating article?
