re-direct generator exhaust

Hi,

I managed to put a Yamaha EF2400 generator into my Keystone Cougar's front compartment. It would be too difficult to take out for use, so I am going to leave it in there. My question is, has anyone made a pipe to extend the exhaust tip to point out of the compartment? If so, what did you use?



Thanks.

Not being a nit picker with you but it's one of those things about not building in any possible way that something can go wrong. It will probably work and you may be ok but it lends itself to potentially being a problem.

OK I didn't see you last post when I replied. It's far better with the fan etc but I wouldn't sleep in there while running it. Generator instructions will always tell you to keep it X distance from any windows or doors. Like a house the code will say that a furnace or other appliances have to vent X number of feet from a window etc. On my FW the bedroom windows dont open so the gen is about 15 feet or more from a window

I wouldn't run it in that compartment. No matter where you run it I would be careful with exhaust modifications as I have worked on a couple generators that people tried to modify and it started to melt the control panels and surrounding plastic. The heat cant escape.

I went round and round with that whole issue. It was a matter of using 2 generators and adding extra fuel tanks etc or getting a heavy unit. I went with a remote start Honda 3000 bolted into the truck bed with an insulated metal enclosure and lid. It has a 12 inch axial fan and vents on the enclosure. Wife can just push the button and dry her hair or run the ac. I dint want to keep messing with anything. Fuel it and change the oil. OH, AND dont drive away with it plugged in!!!

It looks like I didn't include sufficient information as to how I intend to use this set up. There is a 12" house fan that will attach to the left of the generator,running to both cool the unit and push exhaust away and out of the compartment. I have a CO detector in the bedroom.

Not a good idea!

If he wants to redirect the exhaust he could just turn on the exhaust fan in the bathroom, that should suck it into the bedroom.

I have seen accessories for the Honda Exhaust systems but not for the Yamaha.

Here is a LINK for the Honda Generator...

My 2kW Honda gets rather warm when running. I don't think I would ever run it in an small enclosed area just because of the generated heat...

There is also the other reason for putting deadly CO FUMES into the trailer enclosed areas. This is a silent death sentence... If I point my 2KW Generator towards my trailer I can trip the Co DETECTOR just running the generator from my truck tail gate area... This is some serious stuff...

My 2KW Honda generator sits secured to my covered tailgate corner in my truck. When I need to use it I pull it out onto the tail gate... My generator is out of sight when secured and goes where I go...

In my case I only use my 2KW Generator to power up my 30A Shore Power Cable to run my on-board CONVERTER/CHARGER unit to charge up my trailer battery bank. Since my Converter/Charger is a smart mode type this takes around three hours of generator run time to get my 50% 255AH depleted battery bank back up to its 90% charge charge state. Then I am good again to run all of my 12V items from the battery bank and selected 120VAC items from my small 600w PURE SINE WAVE Inverter.

Don't understand how a 2400is would run your AC unless it's a smaller 13k btu one. We had two 2400's because we had to gang them in order to run the 15k btu AC on our Montana. Kept them in the truck bed and, while it was a grunt, I didn't have any problem putting them on the ground and back up when I was 69.

Like others have said, this is a gasoline generator and not designed for enclosed spaces (even though the forward compartment is somewhat ventilated). It's also not designed to have an exhaust extension, so you're risking quite a bit (including your lives) keeping it there.

While I've installed solar and four BIG 6v batteries in our Montana and sold the Yamahas, I did pick up a Harbor Freight 3.2k watt generator on sale (a whopping $300!) that we use for home power backup and take in the bed of the truck for the once in a while time we boondock and need AC. It's not as quiet as the two Yamahas were, but it's also not all that loud. Can't hardly hear it when stopping at a Flying J or the like for an overnight.

Beware from that location the genset will fill RV with CO. DO you think storage area is air tight? The genset may also overheat do to lack of air flow. I see your plan as a bad idea.
Adding on to the exhaust particularly adding an elbow will create back pressure which is not good for the genset and may also lead to over heating.
Simply put you will need to take the genset out of the compartment to use it
