Where does one find "up pipes"

[Triton]

FMCA Northeast area rallies require the use of generator updraft exhaust pipe. A great idea, but where does one find them?

I have seen one at Marty's USRV but a search on their or Googles web site comes up empty with a search for "up pipes" What should I be looking for?

Anyone have a particular preference of one design over another?

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

FMCA requirement of extended Generater exaust pipes, above the roof, does not go far enough. When you get to the rally look around and see some of the home made pipes. Saw one last year at the North East Area Rally that melted, bend in half[used thin wall PVC pipe] and was blocking the exaust. Another maded from stove pipes, yes they do get hot.
Some people just don't get it and someone is going to get either seriously injured or die from these home made exaust pipes.
If your nieghbor is not using a pipe or the exaust is blowing into your MH tell him to either fix it or stop using the generator. We had to complain to the rally host as the guy parked next to us was pumping his exaust right into our front door and couldn't not understand "what my problem was".

From Cummins Onan's "RV Generator Handbook"
http://www.cumminsonan.com/www/pdf/rv/f-1123.pdf:

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 modifi cations 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.

So looks like FMCA needs to revisit their requirement for this as they could potentially face issues by this requirement.

As a supplemental aside, note that AquaHot expresses similar concerns about extending their exhaust pipe. Which, given FMCA requirements, should also be included like they stipulate for the Genset.

Triton.....I bought the Genturi and I think it's well made. Onan will probably never give it's blessing to any extension for liability reasons. Even if they made their own, they could not control where you vented it to or make sure you weren't piping it right into your roof vent.

I'm a home fabricator and usually make a lot of my stuff from scratch so it fits my needs. After looking at the Genturi and it's price, I couldn't build as nice of one for the money.

I did make a nicer bracket for it so I didn't have to attach it to the side of my coach. My bracket is here: Link

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"�

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.

Fred,
I also use Genturi but at NASCAR races I've seen some folks use flexible exhaust pipe directing it either to the front or rear of their coach.

I can not imagine the legal beagles of FMCA evr let tjhis get to be a requirement. At a generator seminar at an FMCA International convention 3 or 4 years ago this very question was posed to the panel of generator manufacturers and all of them unilaterally stated that their respective companies would not endorse any brand. They further stated they would not offer any type of extension due to mega liability issues. As to homemade options you can not regulate, legislate or otherwise prevent stupidity, i.e in one of these posts did not a guy try to use thin wall PVC-duh.

My concern is if the guy alongside of me uses such a contraption and there is a fire with the tight parking conditions any of us could be in mega trouble. Since we always want full generator allowed parking I would tend to skip any rally that made "up pipes" a requirement, Ken '04 DSDP...

Ditto.

[rebelsbeach]

I would be more worried about the spread of Carbon Monoxide than the risk of fire......

I've seem some pretty lucky people in residences when it came to CO detectors virtually having saved their bacon.

Any of you who take CO lightly, or that don't have a CO detector on board should truly learn from this...

It is indeed odorless, colorless and tasteless and ignoring the symptoms can be FATAL.

[Larry3570]

If I were going to make some kind of exhaust "up pipe" for my rig after reading the Onan comments, I'd look at an inline 120V fan (http://www.mcmaster.com 1967K13 - Direct-Drive Centrifugal Duct Fan Galvanized Steel, 303 CFM @ 0", 6" Duct Diameter, $187.50 Each)mounted on a roof-mounted bracket with a length of 6" aluminum (flex?) duct going down the side and ending with a 90 degree fitting supported by a stake. The open end of the 90 degree fitting I'd position so it was surrounding (but not touching) the genny's exhaust pipe. I think such a design would eliminate issues 1,2,4,5 and 6. Perhaps a length of rigid duct on the fan's outlet would take care of issue 3 too.
