Where does one find generator updraft exhaust pipes?
FMCA NE rallies require them.

You can order one from Camping World. It's called a Genturi.

Look for gen-turi, I bought mine at Camping World.

When I was at my first FMCA rally in Brownsville FL this February I was very concerned about carbon monoxide poisoning. On a quiet, no wind evening the stench was unbearable. CO is odorless but diesel exhaust is not. At the time I did not realize my propane/CO detector required two 1 Amp fuses. I had only one installed for the propane detector, none for the CO detector. The coaches were packed so close together one could not leave until your neighbor moved.
I would be interested in knowing if anyone has gotten sick or worse from this problem.
Thank you Larry Shaw for your contribution from the "RV Generator Handbook"¯ <BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content">
Statement Regarding Exhaust Extensions
Cummins Power Generation, manufacturer of Cummins Onan generator products, does not endorse the use of RV generator exhaust pipe extensions. Like all fuel burning devices, engine-driven generators emit carbon monoxide (CO) which, if not safely handled, can produce serious injury or death.
Cummins Onan generators, in conjunction with RV OEM installed tailpipes, are designed to meet RVIA standards for safely handling exhaust gasses while minimizing noise and maximizing generator performance. Improper modifications to the exhaust components can result in unreasonable hazards to the vehicle occupants.
Cummins Power Generation has been unable to this date to identify any commercially available exhaust extension kit which meets reasonable standards for safely handling exhaust gases.
Cummins Power Generation's concerns revolve around 6 areas:
1. Weight: Unless entirely self supporting, extensions add weight to the end of the generator tail pipe which can stress and crack or break the exhaust system parts that are not designed to carry the additional weight. This could result in exhaust gases escaping directly under the coach, and therefore could be extremely dangerous to vehicle occupants.
2. Fit: To be effective conveyors of exhaust, connections & joints must be gastight. Such connections are not guaranteed unless the exhaust extension kit is properly assembled each time it is used.
3. Exhaust Direction: Because exhaust extensions vent at the roof line, there is a major concern that exhaust will be sucked in by rooftop air conditioners, vents and windows.
4. Heat: Many extension designs involve exposed metal that can be a burn hazard to anyone passing by who might contact the exposed extension pipe.
5. Backpressure: Adding an extension may increase backpressure on the engine, and thereby reduce engine performance or cause the engine to fail meeting government-regulated exhaust standards.
6. Warranty: The use of an exhaust extension kit may void the Cummins Onan warranty.
Larry Shaw </div></BLOCKQUOTE>
I had hoped "Up pipes"¯ might be the solution. Well now, asphyxiation from below or asphyxiation from above? Not a great choice. Are the only reasonable alternatives electric hookups or skip the rally?
More space between coaches could be a possible solution. Anyone have a suggestion on minimum spacing for those choosing to use generators?
This is such a wonder forum for ideas. Perhaps we can come up with practical solutions for rally organizers and attendees.

Electric hook up could be provided. Cost would be increased.

I made mine from 2" ABS pipe and a 2x1.5x2 sanitary tee. Seems to work well.
Did anyone see the news story about the guy who died at the last Indy 500 race. He died from carbon monoxide poisoning in the RV camping area.

I have a genturi and think that they should be manditory all rallys due to the exhaust smell and danger.

At a rally ask Onan about using a Venturi on an Onan generator.

TOM: been there, done that. At an FMCA Convention "roundtable" presentation by represenatives from several genset manufactureres, this concept was hashed and re-hashed. The reps ALL said they could not endorse or recommend the use of ANYTHING that modifys their engineered design. After much "hashing" they all admitted that their position about not suggesting "up pipes" was driven more by their legal departments than by concerns about damage to the gensets. HOWEVER, they did make the obligatory warnings about "possible" warranty denials IF such devices "may" have caused a failure.
I've tried to accurately described the roundtable to the best of my memory. Take my comments for what they are worth. I will run the risk of damaging my genset before I'll spew exhaust towards the coach beside me. ED

Just love the fact that the lawers in this country are looking out for my safety.

FWIW, at the FMCA convention in Pomona the RV next to us pumped diesel exhaust directly at us. My other neighbor thanked me for using the genturi. I would rather use it and not worry about carbon monoxide poisoning.

So how long is Onan's warranty? Is it worth a life? I imagine the family that lost their loved one at the Indy race would rather have him instead of the generator. I also imagine the family parked next to them with the generator are miserable knowing that they MIGHT have caused this persons death.
Seems to me that the answer here is a no brainer.
