Hooking up a tri-fuel generator to power a house | sound dampening, stealth enclosure, exhaust

[@GuysPestSolutions]

I see a lot of comments on this video and I could not read them all, so I don't know if anyone has mentioned this or not. I have the same generator and I built my cabinet very much the same way that you did yours. My power went out yesterday and I turned on the generator and it was working fine when I shut the cabinet. However, sometime while I was inside watching TV , the exhaust fan malfunctioned and stopped working, so there was no airflow through the cabinet. Needless to say it got pretty hot inside the cabinet and almost started a fire. I used the same insulation that you did and a lot of it melted. It was so hot that I burned myself when I touched the ignition switch to turn off the generator. The ignition switch is frozen now and I ordered a new one. Once it arrives I will attempt to start the generator to see how much damage there is to the motor. It didn't sound good when I turned it off. All of this is to say, you also need to install a temperature switch that will turn off the unit if the cabinet gets too hot. You want one that defaults in the open position and closes when the desired temp is reached. You can get them from Amazon for about $10 and wire one into the the switch that shuts the unit down when the oil level is low. You just run a wire from the ground to the switch and from the switch to the wire that comes out of the oil shut off switch that is screwed into the motor. That temp switch can then be zip tied to the frame of the generator. That way, if the exhaust fan fails for any reason, the generator will turn off before any damage or fire occurs.

[@unitedstatesofbuild4915]

Dang, Im sorry to hear that. It mustve gotten pretty warm in there. So a fail-safe is critical. What was the indicator this was happening? I was told by the owner of this unit that he has a bluetooth temp probe that goes to his phone with alerts. Its actually intended for a BBQ but it monitors the enclosure temp just as well. It wont turn the unit off automatically though. Im going to look into a switch like you mentioned. A typical air cooled, aluminum head engine can withstand temps up to 375F, Hopefully you didnt get that high. Please keep me posted.

[@johnhendrix4034]

SOOOOOOOOO read my comments ! I'm not a fool.

[@GuysPestSolutions]

@@unitedstatesofbuild4915 Sorry it took so long to get back to you on this. The ignition switch was melted to the point that I could not start the generator. After ordering and installing a new one, I was able to start the generator and it was making some pretty scary noises. It appears as if the motor is okay, but the generator is shot. It looks like the wire windings or whatever just melted. I was not able to get the needed parts to fix it, so I ended up buying a new generator. The foam in the cabinet was the same as you used and it was pretty much melted too and needed to be replaced. I have now repaired the cabinet and installed a new generator, with the heat kill switch. I also put a thermometer sending unit in the cabinet that sends the temp to a receiver in the house, so that I can monitor the cabinet temp. I don't know why the fan failed because it only had about 5 hours total time on it. The fan motor could have been defective, but my theory is that the fan was not large enough to remove sufficient heat from the cabinet. That may have caused the fan motor to overheat and fail. I have now way over engineered the airflow system. I tripled the size of the fan and added a lot more makeup air vents. It's like a wind tunnel in there now. I also decided to use two heat kill switches. One is set 10 degrees higher than the other, so that if one fails the other will still do the job. I am not taking any chances this time. A whole set of the switches cost about $10 from Amazon. The entire repair came to almost $2000 because I failed to engineer in a cheap heat kill switch. Boy do I feel stupid. Anyway, you did a great video. Thanks for sharing it.

[@The_Bearded_Lady]

Came to comment section to ask if it is safe to store more propane and gasoline in the cabinet... but now seeing this comment it makes me worry lol. With a heat kill switch and a temp monitor do you think it would be safe? I could just build a box next to the generator cabinet for those things if needed. Just don't want it to get stolen etc.

[@GuysPestSolutions]

@@The_Bearded_Lady I had a 20 lb propane tank stored in the cabinet when it overheated. It didn't blow up, but I think I caught it just before it did. That could have been catastrophic because the cabinet is located about eight feet from my house. Had it blown while I was trying to shut down the generator, I would most likely be dead right now. The temp monitor and the two kill switches definitely add much needed protection. Still, I no longer keep the propane tank inside the cabinet. I have it stored outside the cabinet and I cover it with a small tarp. I only run the generator with propane to avoid carburetor contamination, so I have two 100 lb propane tanks located outside about eight feet from the cabinet and that is also where I put the 20 lb tank. I don't know if you are aware of this, but you can purchase an adapter for the 100 lb tanks that will allow the 20 lb fitting to work on them. So, the bottom line is, my personal recommendation is to put safety first and keep all flammable materials out of the cabinet. When I look back at what happened I am really embarrassed because I should have known better than to risk my life and my families lives on one fan. All mechanical devices are subject to failure and when that failure may result in serious damage or injuries, it's always wise to have at least one back up system in place and never take chances. Boy do I feel stupid, not to mention very lucky. I hope that helps. By the way, check out my channel. I show you how to do your own pest control safely, effectively, and cheaply.

[@chiyookeynes3007]

Just completed the break-in period and so far the unit is operating perfectly kzbin.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y . I was amazed by just how quiet this little guy is. I kept having to walk down the driveway to the generator to make sure it was still running. In fact, the most annoying noise coming from the set-up is a high-pitched chirping coming from the pressure regulator on the propane line. I suppose it's possible my other propane-powered generator's pressure regulator is making the same noise, but the generator itself is so loud I've never noticed it. Build quality so far is excellent. My only nit is the service panel is a little tricky to remove. I feel like I might break off one of the plastic tabs when bending it back. I probably just need to work out the technique, so will not hold it against Champion.Next week I intend to fully load the unit to charge a large battery pack and will update this review if there's any problem (3000W continuous load vs a rated 3100W capacity while using propane). Absent any trouble there, I'm 100% pleased with this purchase.

Nice box ! The controlling issue with sound reduction is reducing reflective sound waves. Sound (especially higher frequency) waves travel line of sight. The way to reduce their effect on your ear is to include multiple baffles for the redirection of the sound waves. Sound deadening material is helpful as it is harder to bounce off of a soft surface.

I can't get propane cylinders, but I was able to connect the dual fuel system to my home's natural gas line. To achieve this, I had to modify the gas regulator that the generator has. One day I could use it for up to 1 full day with a 70% charge. Many people believe that natural gas cannot be used from the home line, but man does.

Cool build!

[@izzyryder4969]

The exhaust pipe extending outside by approx 10 ft. is a good idea, but making it the same dia. as the generator's pipe outlet is causing excessive back pressure to the engine. That's the reason your carburetor settings were initially off. You effectively changed the engine's overall tuning. It would be less restrictive to use a much larger outlet pipe. At least 3" (same dia. as dryer vent you installed. The larger dia won't build as much back pressure and also help keep water out of engine.

[@One.--]

You beat me to the punch there that is correct plus causing the overall back pressure on the engine which can cause excessive heat & wear. Nice job though

[@geraldarcuri9307]

Purchase a Camco RV exhaust extension kit. It works great, it's easy to install, and will not affect the engine performance.

[@brightchange6065]

Makes sense ... I have the same generator and the way I got around it was not making it a perfect seal! I found a connector that slides over the exhaust outlet but it's not clamped down. The enclosure it outside, the side walls are open to air 6" under the roof, it runs with the front barn doors open, so it's ok if the exhaust is not perfect.

[@funnyfarmdad9997]

I have a Champion 9500/7500 Dual Fuel generator that I want to “hide”. This video is giving me ideas on how to do it. Thanks!

[@weathermannax416]

Mine has a duct for the engine cooling fan shroud and the generator cooling inlet directly to the outside via an insulated flex pipe. That insulation helps to reduce the noise as it is trapped by the fiberglass wool. The heat from the engine and generator head helps push the exhaust gasses out of the enclosure via the 8 inch double insulated stove pipe that is close to the exhaust muffler outlet. I'll used ceramic fiber insulation that is rated to 2,400*F to insulate the enclosure and absorb the sound waves in it's loftiness. Versus a solid barrier that will allow sounds to bounce off of it. Your idea is excellent for the average Joe to do. Not that expensive to make either. Some of us are a little more technically skilled and want to go the extra mile for more added protection in the event the generator "might" catch on fire. As well as the added bonus to help reduce sounds coming from the enclosure. No sense in eating up some electricity with the fan if you have the knowhow to utilize the engine and generator cooling fans. Nice thing about LP and natural gas, the carburetor never gums up like it does with unleaded gasoline.

[@vinyltapelover]

"... the carburetor never gums up like it does with unleaded gasoline." I have two m/cs..a '99 Vulcan Nomad1500 and a '80 Honda 900 custom, a Duro Max 5300 gen, and a A-iPower 2300 inverter gen. I put 91 Octane in all of them, plus for over kill add a little Stabil. The 87 Octane ethanol mix will definitely gum up carbs, hoses etc as I have had first hand experience. I find little performance difference between the 87 and the 91, but the biggest upside is that I have yet to have gumming issues using 91 Octane. So yes, LP and NG are cleaner on parts, but for folks that may not avail themselves of those two sources, for whatever the reason, thecan operate with effectively with 91 octane, as a viable option. Just my humble input as a non technical, non mechanic type guy.

[@nelsonhochberg5182]

I would suggest adding Rockwool sound absorbing panels to the inside of the foam panels. It would further reduce the sound and they are fireproof.

[@dw6015]

No, these types of insulation are not going to benefit, only create problems. For the lamen, would you wrap an engine with a blanket to keep it cool from the sun? No. You shade it. Provide air cooling pathways and paint everything you can flat black.

[@Hema1400]

He could have made a top open baffle or shroud around the fan and a bottom open baffle around the inlet too. That would have done a lot for the noise. Felt board (asphalt impregnated board) would have been good for sound deadening.

[@padraics]

No, sound absorbing isn't the same as sound blocking. You need mass to block sound, not fluffy insulation.

[@Tron-Jockey]

@@Hema1400 - I agree. I'd put some 1/2" plywood baffling on the inside between the inlet vent and the generator and between the powered output vent and the generator being careful not to restrict cooling airflow. Try to get the Genset on rubber feet to keep some of the energy from being coupled to the plastic floor and to the walls, doors and lid which then vibrate and act like speakers. If you put your hand on the outer surfaces I bet you can feel significant vibrations from the genset.

The answer is the first thing he used, horse mat

[@renejackson7652]

I did an almost identical project at home a few years back. I used cement board on the inside because I didn't want anything to burn. Biggest noise escape was through the vents. I had to rig an external baffle to muffle the sound.

Only thing you might want to do is check to see if neutral is grounded on the generator. If so uncouple the ground from the neutral so that you only have a ground at your electrical panel otherwise you will get current on your ground wire in your cable from the generator to your panel.

Besides all the comments worth considering, I’d say that a safety shutoff in case of fan failure would be a must, my friend! I do a lot of commissioning and QC not to mention my own setups and safety is always the number one concern. A backup generator is pretty useless on a burned house...

[@unitedstatesofbuild4915]

I agree, do you have a product that you use to hook up a high-temp shutoff circuit?

[@peteaulit]

@@unitedstatesofbuild4915 I never had to do this in a DYI situation, so I would go the path of least resistance and try a temp sensor wired to the generator shut-off circuit (the "off" button) to star and try how well it works by unplugging the fan and closing the box and wait. It shouldn't take long...

[@nc818]

Yeah imagine if that generator caught on fire and the only way to put it out would be to cut off the natural gas, which is less than 3 feet away. this generator is in the wrong place, also I don’t see the point of putting it on the house except or for aesthetic purposes, I wouldn’t sacrifice safety for that.

[@yari369]

That enclosure will definitely outlive that generator

[@duaneroepke8840]

I hesitated in asking this stupid question but here it goes. For the cost (just guessing), wouldn't buying an "inverter" generator been the way to go as they are very quiet to start with even the larger wattage units. Build a simple 3 side wall unit/blind with 6-10in air space between wall and roof. This could even be made "knock down" and put together with pins and stored away. No worries about over heating, exhaust will take care of itself, still be out of the weather, and easy to maintain. Still have a provision to chain it down but could be kept inside your garage and used for other projects and not just dedicated to this one purpose. Quick disconnects would allow the use of propane or natural gas. I can appreciate that this also is being done for out of sight out of mind and for aszthetics but even a simple overhead weather cover with removable sides in the backyard would do and still be quiet.

[@whiskeysauer]

That's still pretty darn loud. I have my diesel gen setup inside a concrete enclosure. I also added an exhaust fan and pipe exhaust through a port on the side. Those both face to the rear of our lot. The entire enclosure is then setup about 100ft from the house. The conduit runs underneath a sidewalk we installed and leads into the house where we can operate an ATS. It's a great setup. You can't hear it running inside the house outside at all.

[@Random-rt5ec]

That’s a nice looking setup - Because my neighbors are just a few feet away I’d need to find a way to reduce the sound even more I might have to build a concrete box.

[@kezzatries]

Yep use lead, perfect sound insulation. Use sheet lead, want to experiment? Just lay sheet over the wife's food mixer, you'll be surprised. Easy too.

[@unitedstatesofbuild4915]

or over the wife....the food mixer is quiet in comparison

[@andytachibanalover9495]

Congrats man, what a perfect, professional job you did installing. What was the final cost of this install to the homeowner?

[@morenoraul13]

I’ll like to know I live in the eastern part of the state. I would gladly pay this dude trip to install me one.

[@teter129]

Not my speed. Buts its nice to see quality installation and craftsmanship! Nicely done, I wish all contractors performed the way you do!

[@rterry2752]

Nice work, nice having all the tools to do a job too.

[@unitedstatesofbuild4915]

Thanks 👍

[@manzam01]

I love the video, back when I was looking for this type of video 3-4 years ago, the dual fuel generator was available but nothing out there on how to install. I did buy a Champion 11.5 Kw whole house backup generator and installed the entire thing myself and works perfect, no issues but was really expensive over the portable generator. I think I paid $2400 and was really heavy trying to get into position, no cost to me over that since I installed but really heavy, no wheels.. I like the portability of your kit. I would say no way that small exhaust tube holds up, you need a much bigger exhaust area, you have to look at it like resistance, like a muffler. The Champion and Generacs blow it all out over a large area, I would expand it like a furnace exhaust and flow it out where you want it but the install is very nice. I am here for the box idea, I have a fence around my generator but I do not like the look, it helps, I screwed in mats to muffle the sound and works, I just do not like the fence look, large, takes a lots space, looking for something else, I think your surround idea fits the bill. For batteries, I would recommend the following, maintenance free and avoid the garden batteries, they just fail constantly. Get a solar battery maintainer, so battery stays charged, start up the generator every week to be sure it works. tinyurl.com/t8twxf8w

[@JohnDoe-ut3sz]

amazing set up. id rather pay someone to do this for me. this is beyond my skills.

[@michaelgrimm4689]

Ton of work for reduction of 12 decibels, but very impressed with the caliber of craftsmanship.

[@texaslawdawg1902]

There is some good logic here. I’m not in a trade, so I have no comment regarding the natural gas hook up. However that exhaust run is really long. Are you concerned with increased back pressure or burning the exhaust valves? The Duromax is deafening loud. Ask me how I know.

[@unitedstatesofbuild4915]

Im not too worried about the valves. When I was researching this project I came across a lot of info on people routing RV generator exhausts much further. I believe the slow sweeping bends and the ample ID's of the tubing I used should present 0 problems. Thanks for watching.

[@nancylyles1570]

backpressure or burning valves would come into play if he removed the muffler, the muffler is also built for this, so he will not have backpressure issues.

[@FBPrepping]

I hate when skilled people makes things look easy. To cut a straigth line on a board with a circular saw in the air? come on dude. You're an expert. Great video. And the chain lock plate is a great addition. Thanks.

[@wilsonsoriano2003]

What a perfect professional job. If you don't mind me asking how much was all this work not including the generator? Do you happen to know anyone that can do the same in Houston Texas?

[@theendofallthingsisuponus1575]

should not run u more than $2500.00 but there are many ways of doing this for $1500-2000 watch more videos

[@dbrown597]

This is truly a great job. I enjoyed watching it

[@richt8297]

Great job. The only thing I would have done different is I would have spaced out that exhaust pipe away from the house wall about 3 inches or so and put some exhaust header heat wrap around that flex pipe coming out of the generator muffler inside the cabinet.

[@unitedstatesofbuild4915]

Probably wouldnt hurt. I kept it unwrapped just in case they ever unhooked it and moved the gen. The exhaust is cool enough by the house that I didnt feel like it needed to be spaced anymore. That said this is stucco, if it was wood or vinyl then I def would space it further

[@6actual911]

My 13,000 watt gen overheated and melted my box. DO NOT put your generator in a plastic garbage can hut. Build a solid structure

[@smithn.wesson495]

You have a really good idea and are very talented. There is no doubt this system will work out well. One question - Add up the cost of everything you spent, from the generator, pipe, tri-fuel adapter kit, caulks, tools, - everything for the entire project. Wouldn't of been cheaper, faster and easier just to have a Generac Full Home Standby permanent generator? Generac 10kW with Wi-Fi smart phone control starts at $2,759.

[@unitedstatesofbuild4915]

Maybe. My part was just what was shown in the video. Id be curious to know the answer too though

[@5thGenNativeTexan]

Full home will also require a transfer switch... my Generac ATS (automatic transfer switch) was about a thousand. Gas plumbing and electrical hookup will run a thousand or so (there's a lot of wiring to be done to install the transfer switch for whole house), generator pad if you need it. A DIY install, subcontracting out the parts like electrical, can save you a lot of money, but I'd estimate you're still looking at $2-3K on top of the generator itself. I have a Generac 27KW QS (quiet series), which runs about $11K, and my turn-key install was $15K. So $4K of that was the transfer switch, electrical, concrete pad, and gas hookup which was slightly more expensive because the had to have the gas company run a new gas line and meter because my house gas meter was on completely the other side of the house from where my power meter and gen install was. I did my whole house install 11 years ago and have been very happy. You can see the video at kzbin.info/www/bejne/mpOvh3qPjJpshrs

[@prettygirlus9008]

In 2015, I got an estimate from Lowes for a whole house 20kw Generac install w/ transfer switch for $5500. I foolishly didn't want to spend that much. The same install was $10,000 in 2018, and surely more than that today. I ended up buying a Sportsman GENTRI9K tri-fuel portable generator rated at 9000 watts surge/7200 watts run, but surely 25% power loss when running on NG. Price in 2018 was $1500. Can be a little finicky and unstable on NG, but will simultaneously run the fridge, all lights, two fans, sump pump, garage door opener, and two 8000 BTU window AC units. Thinking about buying the Duromax XP12000EH and adding an NG conversion kit.

[@smithn.wesson495]

prettygirlus900 I own the Duromax XP1200EH. A great generator and have also considered a NG hookup to make it tri-fuel. Be sure to do you load calculations carefully as the amount of running current will drop significantly with natural gas through a LP gas system. It would be awful to buy the Duromax , new regulator and adapter kit to end up short and not enough power for a full house backup. Doing the math and load calculations is extremely important.

[@artinist]

wow, clean install, all done right.

[@GetOutOverland]

Well done sir! Excellent build.

[@PJ-ee5mc]

You have done great work here with a very good eye for detail. For what it's worth I think that the relatively long run of flexible tubing for the exhaust will create far too much back pressure for this motor. I might have used 2 inches or more, but at its present size I think there may be issues down the road and it may make the engine run hotter than it should. Just my opinion.

[@unitedstatesofbuild4915]

I appreciate your thoughts and you may have a point. However, when I researched this project I found a lot of instances of people with RV's doing much longer exhaust runs than this without any problems. I guess time will reveal the answer.

[@jeffreyrood8755]

As it has been said, you can add a muffler to the generator and loose a lot of noise. I'd have to say I would not have spent that much money on such a small reduction in sound. Concrete backer board inside or something else to deaden. The fan turning up and in a flew set up might help. It seems the fan and opposing vent are where the weakest points are. But very professional install for certain.

[@cessargro]

Great installation and great video. Thanks for sharing

[@jaker450]

12db reduction is not a "small" reduction in sound. At 69db, it's nearly half the sound level of 80db. www.chem.purdue.edu/chemsafety/Training/PPETrain/dblevels.htm

[@brightchange6065]

Really good job. I have the same generator and came up with a similar concept for exhaust ... but I like your's much better ... might redo it before winter. I couldnt find exhaust pipe that fit over the exhaust port. I made a double wall out of a pipe inside a pipe. I used a 2" iron floor flange and 90- degree elbow to exit the box. Inside is 3/4" dia pipe that fits inside. The exhaust pipe I had was the same OD as the exhaust port so I used a connector that slides over it ... You did a very nice job.

[@BState]

The reflective layers from inside the box will cause the generator to overheat, it's gonna be like an oven. You need to remove or cover them to avoid the radiated heat from the generator to be reflected back to it, not the other way around. Also, rockwool would be more than twice as efficient to achieve what you wanted to achieve. Styrofoam transmits sound almost like wood, it doesn't dampen it.

[@gerardred8147]

Excelent video. Thank you for the attention to details on a job very well done. It teaches the issues to deal with and provides a realistic benchmark for expectations. I am facing a similar task and thinking how to tackle it, now I know much more. After studing this video, and reading the comments, I searched for videos showing the effects of installing a car muffler to the exaust pipe. It actually lower the noise in about 6 decibels. Looking for better materials, I am thinking on making the box out of steel frame and thick fibrecement walls to make it non combustible. Using inside rock wool as sound insulator, which is also a good fire barrier and better as sound insulator. The set up should be very similar to this one, but topping up the exaust pipe with a wide chimeney hat.. I would no use hinges, nor two doors on the front, perhaps just one sliding panel going in from the top down. I think that on this way, less noice comes out.

[@veritasvincit4178]

Great job. Maybe running the exhaust through an automotive muffler and also aiming the exhaust straight up would greatly lower the dB

[@frontxxrunner]

I've seen people use automotive mufflers to try to quiet a generator and the results were disappointing. I think aiming the exhaust straight up would allow rainwater in

[@embracethesuck1041]

I LOVE my Dewalt cordless oscillating saw. It's the tool I didn't know I needed until I had it.

[@unitedstatesofbuild4915]

I read somewhere that they were derived from the medical saws that doctors use to remove casts.

[@JackAgainski]

Another good sound deadener would be to collect old egg cartons and staple them to the inside walls with the inside of the carton to the walls and the top panel. They break up the sound waves.

[@Vlfkfnejisjejrjtjrie]

Not really. Any novice with a homes studio knows this does nothing. In the case of the gen enclosure, it could be a fire hazard.

[@JackAgainski]

@@Vlfkfnejisjejrjtjrie Only the foam type will do any good. The cardboard ones are useless. Acoustic foam is a better option, but you have to pay for it.

[@urself25]

I'm looking to buy this and do the NG converter instead of buying a tri-fuel. How many watts can you draw on NG compared to propane? Tri-fuel generators seems to loose lot of running watts between the 2. Thanks.

[@Honestandtruth007]

@@urself25 Good question Every generator is different. Let just say on the Running wattage at 7,000 watts on Gasoline and Propane running watts would be 6,300 watts and on Natural Gas would be 5,700 watts Remaining because Natural Gas is a lot lighter than Propane.

[@electropalsceo]

I loved the whole idea of trying to suppress the sound, but it seem to only bring it down a few decibels, im not sure if it was all worth the time and money. Thank you for sharing , this help me decide to go with the genetic model .

[@bennoah1673]

you cant screw the foam on, sound transfer point. use adhesive.

[@zhasouris]

Decibels are measured logarithmically so 12 Decibels is pretty substantial, but I bet you could get a better decrease with some fine tuning.

100% no doubt home owner is lucky they found you to carry out their will. Not easy to find people to help w/custom projects. As far as this project I would have kept it a totally temporary installation due to permit codes and home owner insurance etc. If you are going to do a permanent install better to go w/full size "Generac" system that will comply with all the laws and codes.
