From what I know, the surface area of the two tanks is the same, as determined by the diameter of the tank. Of course, 30's just have more LP in them and will run longer!

PS: I KNEW you could do it! Now you're intimately familiar with your generator, and can troubleshoot any problems with ease.
Thanks for the update Lew. The place I bought the propane bottles told me that 20# bottles "might" not run the gen, but then again they did not know what size generator I was using. Just reading now on the US Carb website it states a 20# cylinder will run up to 10 hp generators. Anything larger will require larger bottles.

It's good to know the 20# cylinders will run the generator no problem. I had planned to upgrade to larger cylinders on the AS regardless for more run time (they barely fit on the 22' ccd by the way) and wanted to use all same size cylinders for easy change out.

You are right, installing the conversion gave me a much greater understanding of the generator, especially how it operates off the propane, just like installing the converter and battery monitor gave me a much greater understanding of the trailer's12v electrical system and how to manage it. Thanks again for your encouragement. jk

Yamaha 2400

A few comments:

1) I don't think storing 1/4 tank of gas is necessary at all. Just make sure the gas switch is off, which is the way to stop the generator anyhow once it is converted to tri-fuel. USCarb even provides a sticker with their conversion kit that is to be placed above the "on/off" switch that says to NOT use the switch to turn off the generator - so, bottom line is on tri-fuel conversions one turns off the generator by turning off the source of fuel.

2) The 2400 can definitely handle 11,000 BTU's. When it comes to 12-13,500 it depends on the make, model and draw of the AC. That is why some folks report no problem and others can't get up at all.

3) I solved the storage and transport of the generator and I recommend my solution to everyone. A Contico rolling bin - the black heavy duty model with yellow wheels on one end, a handle on the other with a large yellow clamp style clasp in the middle...the 2400 just happens to fit in the this baby perfectly even with a little room at one end to spare for extra parts, extension cords, quick connect hoses and the big conversion regulator mounted on the end of the 2400. It allows for easy lifting in and out of the truck/SUV, keeps it weather/damage proof, keeps the minor fumes left in the gas tank from filling the passenger compartment and makes moving it on the ground a piece of cake. The rolling bin is available from Northern for $69.99 and beats the heck out of buying or fashioning a cover and/or wheel set. If one were to modify the bin to provide exhaust, fresh air vents for cooling and intake, I do believe that this bin would also be a near perfect foul weather housing when operating and likely further dampen the already low decibles the 2400 puts off.

4) USCARB did have some growing and moving pains - and, yes...one can purchase the generator separate from the conversion kit and save a few bucks (USCARB doesn't seem to discount the 2400 off of suggested sell price as does Wise and others), and yes...it is reasonably easy (and interesting) to do the conversion. When you do need technical support from USCARB, the best if not the only way to easily get it is by e-mail with the techncial department. I not only got all of my answers quickly, but had the advantage of getting them all in writing. Seems they can handle e-mail responses much better than telephone.

5) I did a lot of research prior to choosing the 2400. Yamaha built this generator for rv'ers that could not get by with 2,000 but didn't want the weight of the 3,000. They chose the 2400 range due to its capacity to start virtually all 11,000 btu A/C's and many of the 13,500 that have the newer lower load start-up systems. A single person being able to pick up and move the generator around and lift it in and out of back of a tow vehicle was a key objective for Yamaha. They have succeeded in providing a light weight package that can handle relatively heavy rv duty with low decibles and easy conversion to tri-fuel...without voiding the warranty, which is really crucial. And, yes putting two of these units together produces almost 5,000 watts of capacity and over 30 amps as well. I will put my Yamaha up against the quality of Honda and that is saying just about everything when it comes to portable generators.

I appreciate this forum and enjoyed contributing my first entry. regards to all...

I also solved issues of the storage and transport of the generator, and highly recommend it: http://www.airforums.com/forums/f448...ccd-34487.html

The manual refers to some code somewhere that says you need to keep a the gas tank a quarter full. I thought it was redundency- in case you forgot to use the shut-off. At any rate, I've kept the tank a quarter full and store the generator under the dinette table when traveling. I haven't had an odor problem at all. And yes, it runs the 11k btu A/C just fine.

Really? My manual (Yamaha EF2400iS, LIT-19626-01-23, 7CF-28199-10) makes no such claim, and neither does any material from US Carb regarding the trifuel conversion that came with it.

The only mention of storage in my Yamaha manual states that all fuel should be drained from the tank and carburetor, among other things.

What is the purpose of maintaining 1/4 tank of gasoline in the unit, when using only propane? I'd sure hate to mess up my fairly expensive investment, so if I must, I will put some gas in. But I'd need to understand what that gas is there for, before ensuring it's always there, changing it out regularly to keep things from getting gummed up, etc...

Cheers,
-jd.

I've been keeping my 2400is empty of gas, and it still starts up quickly when I do my regular test-run on propane between trips.

That's one of the beauties of using LP for a fuel. I have an Onan 7000 that I converted to propane for a back-up gen in FL and run it maybe twice a year for testing. It starts right away with not so much as a burp!

Yup - Glad to have the confirmation - I think Wayne&Sam should get rid of the gas under the dinette scenario.

I just read about an attempted theft of someone's Yamaha generator here:

http://www.rv.net/forum/index.cfm/fu...d/20205575.cfm

Executive Summary:

He had it chained through the handle. They unbolted the handle, but it was too hard to carry away and stashed it nearby. The owner found it. He follows up with locking sugesstions.

he should have put a bear in the box and wait for the thief to return. i'd expect that the thief watch the recovery too.

My trailer is on its way to Montana with my wife at the helm, so I can't pull out the reference in the paperwork. It quoted some regulation. My assumption was that if the tank was empty and the gasoline shut off was accidently left open while running on LP, the empty gas tank could fill with LP. The purpose of the 1/4 tank of gasoline was to prevent LP from entering the empty tank.

Hmm...think I had better get on the blower to US Carb for some updated literature and details before I do something wrong with my setup and go kaboom.

I do use the LP tank shutoff to let the gen run dry, before switching off switches, so I'm probably safe. I really really want to avoid any amount of wet fuel slopping around in there, except maybe in an emergency (and I'm out of LPG). Thanks for the head's up.

Cheers,
-jd.

I hate to jump in here and burst the bubble but I based doing business with US Carb and having my Honda EU2000 converted on a lot of the threads of this fine Forum, including this one.

My experience with US Carb has been a nightmare. Before you do business with these people and let them take your money like they did mine and another member of the Forum, do yourself a favor and read through the following thread all the way to the last one today.

http://www.airforums.com/forums/f448...ded-46854.html

Buyer Beware! US Carb has unacceptable non-existent customer service and an unreliable product. I'm still sitting here 45 days + after they cashed my check, having spent SIX DAYS of total time trying to get my genny to start. So far I'm over $1300 out-of-pocket on what is now a 50 lb Honda / US Carb boat anchor!

I have a Yamaha 3000 I got this fall and plan on having US Carb convert it to propane in the spring. I have about 140 hours on it now with gas and the only trouble I have had was after about 40 hours it shut down on low oil so I thought that is normal at break in, so I filled it up and changed oil at 50 hours as per instructions. It shut down again after about 60 hours so I topped it up and haven't had the need to run it much more. I was wondering if anyone else has had this trouble? I have included some pics of how I set my gen. up to be able to use it without taking it in and out of the truck.
