AquaHot Exhaust

[Jeff Watt]

Thought I'd order the GenTuri as a Christmas present to myself........

Amazon.com has it, but won't ship it to Canada  

CW will ship it, but costs $54.96 for shipping.   ??)

I think I'll wait until I am in Texas in February and go to a CW and pick up one or two.

For those of you that are considering to reroute your genny or Aqua/Hydro Hot exhausts be sure to check with the manufacturers installation manual. On my Hydo-Hot the pipe has to be of a certain size, can be no longer than a certain length and have no more than a limited number of bends. I'm sure that the Aqua-Hot and generators have installation limits or requirements also. Remember it is a noxious gas that can and has killed in RV's. Marty

Thanks Henry, but we are going to run an extension, clamped with brackets to the generator exhaust, using a section of flexible ss.pipe to follow it over the rear axle and then solid tube to the rear flap.

I don't know if there is any significant differance between the AquaHot and the Hurricane, but I tend to agree with Joel, I can hardle see or smell anything once it's been running for a few minutes.

Question though about running the gen set and aquahot to the rear.  Is there any good reason they can not share a common exhaust?  Of course you may need to adjust the diameter just a touch, after the juction, but it might simplifiy matters.

[Joel Ashley]

Seems to me that Marty and others have the best solution, rather than going to the trouble of routing to the rear, where the fumes still exit at ground level, and may yet annoy some proximal neighbor.  A Genturi and a few inexpensive suction cups would be my choice - the exhaust needs to go UP^.

Just my 2 cents

Dick,
The problem with a shared exhaust is that the Hurricane only produces a slight positive pressure with a small squirrel cage fan to create the exhaust flow, whereas the generator has a fairly high pressure exhaust flow. With there being as much difference in the exhaust pressure as there is, there is a good possibility that if both units are running at the same time, the Hurricane would probably have operating problems and possibly represent a fire danger, if the exhaust was not enlarged very substantially. So I do not think that a combined exhaust is a good idea.

As you lengthen the exhaust, you are adding back pressure to the system, and I'm sure that there are limits to this. The fewer the bends the better, the larger the diameter probably the better.  I would think the system would tend to carbon up more, making it likely to not burn as cleanly with higher back pressure.

My personal solution is to have the system as clean burning and well adjusted as it can be, and I find under those conditions a slight odor on star up, and hardly detectable once warmed to temperature. If someone is sitting outside next to my coach near the exhaust area, I shut the system off. Under those conditions, it is quite warm outside, and I can live quite well without it. I do not dry camp with a crowd around, but can see the need under certain conditions, when the wagons are all circled, to extend the exhaust. Perhaps arranging the coaches with the exhausts facing each other, when dry camping, would be enough.

One of the big issues in my mind is having a very clean burning system.  I have been next to some coaches where they are constantly blowing smoke out of the burner system when it is running...a lot of smoke. That is hard to live next to, even for a day...

As a service tech, I have no negative reports on the genturi whether self made or otherwise.
I always use one myself.
Thanks

I was thinking about that.  My gen exhaust has about 1.8 in/sq area and the hurricane about 3 in/sq.  If one ran a 2x3 box tubing instead of the current 1x3 there should be more than enough area to prevent backpressure.  Plus, if one merged in the smaller tube correctly, you could even pull a negative pressure on the hurricane.

Just saying, in theory it might work nicely with some thought.

[Edward Buker]

Because the exhaust pressure of the generator is so much higher than the Hurricane I do not think you would ever get a negative pressure on the Hurricane. If you wanted to go to a single exhaust pipe having one fabricated with an internal divider wall within a rectangular tube arrangement keeping the streams isolated  (or two rectangular tubes tack welded together) would probably be the safest bet. This all seems much more of a pain than it is worth given the Genturi is available and has good reports.

I have noticed a couple of stripped mounting screws to the brackets of the aqua hot exhaust that holds the piping to the bay floor. I increased the screw size and it held for awhile. Any issue with drilling and through bolting with some large washers for this issue. Wondering if someone has gone through this before. I was a little wary given Beaver/Monaco did not do this in the first place.

Ed,  on mine we drilled through and put bolts in from below so that I can unscrew them from outside underneath. no issues.

I have a Gen turi sold by CW that I will sell.  I have used it at rallies, and if I remember right, FMCA bylaws state gen exhaust should be routed up over the coach or something to that effect. It works well for gen exhaust, but have not tried it with the Aqua Hot. And even if you route the exhaust over the axle and out the back, the exhaust is still near the ground to be moved by the current breeze. It would be a lot easier to modify the Gen turi to fit the Aqua Hot, than to run piping over the axle and all the way out back.

Thanks Jim,

 One of my winter projects was to fix the Aqua Hot exhaust pipe bracket that was stripped out. Your info is a help here. Always something...

I went to Lowes and bought collapsible heating pipe. 4" around and extends to 8 feet. Gives you enough flexibility to move the end where it is in-offensive to you and your neighbors. Not the best looking but effective. Cost as below $5. Collapses to about 3' and stores on top of my HH.

I've had the Genturi for four years.
It came with mounting screws and adhesive pads.
I chose the pads and they have worked just fine.
The elbow from the genturi fits perfectly in the exhaust from the hydro-hot.
Takes less than a minute to set up or take down.

Happy holidays and travels,
