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...
I suppose that there is always a chance of picking up some of the fumes. Wind direction, how close the roof vent is to the exhaust are you venting out or drawing in fresh air. Our fan works both ways so there could be a chance of bringing in fumes. My black/gray tank vent is about 3' away from my fan so it is possible to pick up that smell too.
If your nose doesn't detect, install a carbon monoxide detector.
Could you not struggle with an extra top extension only when you determine wind direction to be an issue?
Every busnut needs a carbon monoxide detector!!!
Yes, the exhaust gases from your own, and your neighbours' can find their way inside the coach.
You can't smell CO, it is a silent killer.
Safety first, anything onboard burns a fuel, go get one from your favorite big box store, or online.
Happy coaching!

Just remember that those things have expiration dates just like tires. I picked up a bunch that were discounted one time only to discover they only had about a year left on them, :o Something about the half-life of the radio active particle in them. We have one now that doubles as a night light and screeches to let us know the power has gone off and it's switching over to battery, going to miss it when it has to be replaced :'( :'( Yeah right, Will
I've never had a problem with the generator exhaust, since my genset sits above the engine and exhausts out the roof. However, my Webasto exhausts down from the third bay so I made a 90 degree elbow to channel the exhaust to the side. At one time I had a complete system to exhaust it above the roof, but keeping the windows closed works just fine.
RV stores sell an above the roof exhaust system for generators which also works with a Webasto/Aqua Hot.
Hi,
Anybody have any experience with these:

This seem to allow a mix of exhaust and fresh air to be released at the roof line of the coach.
Thanks,

I had three high end powered detectors in my house, they said to replace every 10 years. Yeah, right, I like most people said. They turned out to have a clock in them, they turned off and lit their siren after ten years plus a couple of days. All three within a week. I learned that lesson! I replaced them with even higher end models that have a 10 year back-up battery that never needs to be changed.

Neat idea. The elbow should extend further into the PVC to ensure the venturi effect. Any slight crosswind and that gap will allow the exhaust to blow back and not up the stack.
One could very easily fabricate their own for a lot less than what these are advertised for.
this is what I did to get rid of the boiler diesel stink . no more stink !

2.25 " stainless steel pipe 1 90 deg . and 2 custom mounts total cost was $125.00
no problems as yet

One has to be careful adding a pipe to the Webasto or Pro/Heat they have very strict limits on the length and size of the exhaust pipe to remove the 600 degree exhaust temperature they produce,I was told not to add a stack
I don't know, I used a stack above the roof for the Webasto and it didn't hurt anything. How much back pressure could a 1 1/2" open pipe create?

I don't have a idea just what Webasto told me and the instructions do limit the exhaust in length
I have seen busnuts popularly using downspout piping for temp roof exhaust extension use.
The trick with extending a Webasto pipe, is upsizing the pipe on the extension.
Back pressure is a big no-no with any of the coolant boilers.
happy coaching!

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.

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