becken63 · 02-03-2020, 07:16 PM

2008 winn adventurer 35A generator exhaust getting into bedroom from rear pipe placement. Sets off alarm. No leaks in pipe. extend pipe further out??? or add a curved pipe to extend it up??? other ideas?

How long has it been doing this? Has the location of the exhaust pipe been changed recently? Can you run a wire or cable into the exhaust all the way to the generator connection to make sure it's not blocked?
If you can't figure it out, get it to a pro for diagnosis. And don't run the generator until it's fixed.

Sounds like there might also be a leak at the top or some area that is hard to spot.

There's a product called GenTuri that is a pre-made exhaust extension that takes the exhaust up and out above the roof line. It removes and breaks down for travel. It might solve your issue.

no leaks in pipe. not plugged. happens when wind is blowing into the pipe. I just need to extend the exhaust . sounds like the Gen turi is what i need. thanks for the help.

Make sure you shop around online for the Gen Turi, prices vary significantly.

Interesting idea, I am assuming that with going from the small pipe to the larger GenTuri pipe there would be no problem with creating back pressure ? Looks like my Navion has the perfect mounting location, the ladder ..

Here's a link with pictures. You can find it cheaper elsewhere. I have had one since December, 2015, still working good.

You mount a metal socket adapter on your current generator exhaust pipe. The Gen-Turi has a metal 90 that mounts into the socket and is held there with a pin. The hot generator exhaust mixes with air so that the plastic tube that exhausts up does not get hot or melt. The metal 90 does get hot, too hot to touch. Includes bungee straps with hooks to hook to ladder or it comes with stick on wall mounts you can stick on the side wall if need be, that the bungee strap hooks can connect to.

Gen-Turi

I have a 2008 itasca suncruiser 35a. previous owner put a chrome extension that has a curved end pointing down. We do not have any issue with exhaust.

Had the same issue on my Brave. Exhaust fumes would accumulate under the coach. Put the Gen Turi on it and solved all the issues. A great side effect was that it also quieted down the noise. Not a large amount but, it was noticeably quieter. Bought a new Forest River Sunseeker and moved it over to that coach.

I used 8' of 3.5" O.D. / 3.25" I.D. 6063 T52 Aluminum tube attached to the ladder to make a 'gen-turi' that is left in place (no need to repeatedly install and remove):

There are other photos there. Here's one of a rig owned by someone who used my idea:

Let me know if you have questions.

I'm sure you have thought of this, but depending on location, you may be able to loosen the existing exhaust pipe and situate it further forward or to the rear of its existing location. My generator is located in the rear corner and the exhaust pipe was directly under the window. I re-arranged the pipe so it now sticks out the rear of the motorhome and away from the window. No extension needed.

That's a good suggestion. Certainly worth trying first before going to more trouble and expense.

I found the exhaust pipe on ours very easy to rotate (and remove entirely).

The exhaust pipe from the generator is vertical and the 90* elbow can be easily rotated once the pipe clamp is loosened. At least that was the case with our QD3200 genset, and our rig was going on 10 years old when I did the mod.

I was expecting it to be badly rusted/corroded but everything was in decent shape -- even the clamp was reusable. Pretty surprising actually.

We run our generator for days at the NASCAR tracks and the GenTuri tube is a must. I use a suction type mount on the back cap vs mounting the clips to hold the tube but each camper will vary in needs.

For some reason the photos do not seem to be coming through.

Perhaps it's operator error on my part. Here's another attempt:
