      Claude Perrault, how did this project go for you? I've been researching the Firman Tri-Fuel generator with the idea of plumbing natural gas from my furnace in my garage. I want to run the generator in my garage and vent the exhaust outside. Any advice?

    The original problem was getting the exhaust OUT the garage while leaving the generator inside. No problem. Problem solved. But how? How did you get the pipe out of the garage? Did you cut a hole in the door? Wall? Crack the garage door open and run it underneath? How about the temperature of the pipe when the generator has run for several hours. What's the story with all that?

    nice job which gave me some good ideas. I am doing in an enclosed shed and will bend 90 degree in order to run exhaust higher to lessen carbon monoxide. will probably install a rain cap to keep water out. going to use conduit for pipe.Does that permatex red rtv gasket seal cure and harden up? thank you.

    • @TheChemistDIY
      @TheChemistDIY  ปีที่แล้ว +1

      Thanks for stopping in and commenting. To answer your question, once cured, it's more of a hard rubber. For lack of a better example I would say like a kids supper ball depending on the thickness of course and malleable to an extent.
      That said, Always be sure to use a carbon monoxide sensor if placing in a room that's exposed to traffic. Better safe then sorry.

  • @tist203

    Very nice. What i like about yours compared to other solutions is it does not damage the original exhaust, able to detach flex tubing if needed and air tight seal. Correct me if im wrong but your tubing is all wider so less back pressure.

    • @TheChemistDIY
      @TheChemistDIY  ปีที่แล้ว

      Thanks for stopping in. Yes you are correct.. no different then say for example putting a quarter over a dime.. I've ran the generator for long periods without it ever stalling or choking itself out so back pressure is really not an issue. If you're really concerned with that I suppose you could add a manifold for a fan to introduce cool fresh air into the tubbing chamber, forceing freash air and hot exhaust out..

    I just happened to run across this video... I made a similar video a little before this I think. I knew there had to be a better way.... I just cut grooves in the exhaust tube and used a hose clamp (technically it runs outside my camper on a slide tray anyway). However, it does come loose from time to time. I have a couple more mods to do and this looks like a great one to add to the list!!

    @DavidLaFerney 3 ปีที่แล้ว +1

    Great job! I use my (exact same) generator to power a travel trailer while dry camping. I need to turn the exhaust straight up so that it doesn’t get too hot on other gear in the truck. This increases the inside diameter of the pipe quite a lot so it shouldn’t be too much restriction even turned 90 degrees. I might try doing that with pipe fittings instead of flex pipe. I guess it will be important to not put any stress on the two bolts since they are only intended to hold the spark arrester.

    • @TheChemistDIY
      @TheChemistDIY  3 ปีที่แล้ว

      Yeah, I was suggest creating your own support hardware for the heavy piping.. just make sure to attach it to things that can support the heat transferred from the exhaust pipe to your bracketry. The exhaust pipe does get extremely hot and the last thing you want is to melt, burn, or catch fire to the object the bracketry is attached to.

    +So your saying to use the silicone to hold the spark arrester in place? I can’t see how in will stay in place with the larger 1” flange and tubing . I have the same generator and at the 3/4” reducer I screwed in a short piece of 1/2” conduit that holds the spark arrester perfectly. Just use a 1/2 in conduit coupler to hold it in place. One screw removal to clean spark arrester.

    • @TheChemistDIY

      Thanks for the props, greatly appreciated. One quick note about adding a second exhaust. Since this is a small engine it may not be able to handle the double filtration back pressure. Its one thing to add a larger diameter tubing to extend but another thing to impede or restrict the amount of exhaust extrusion, doing so may cause the engine to choke out. But if you do try let me know how it goes and what exhaust muffler you used.
      Also I'm curious to know why you want to add a second.

      In a perfect world things will go according to plan but I'm not one to leave it to chance.. always error on the side of caution and pick yourself up a carbon monoxide sensor with a LOUD audible alarm.
      Even if our modifications work flawlessly there's always the chance of it leaking from some other place we didn't have our hands in.

    • @Alvin-1138

      James Moreno's workmanship and video are excellent; but remember that there is wind/air flow at the exit of the pipe/hose. Imagine the wind shifts and blows the exhaust back down the pipe.
      And there is nothing to force/exhaust the fumes to move through the pipe. Just a thought.
      Good luck.

Since the tube is flexible to any position it free floats through a larger diameter hole in that vent.. but if you need to creat a seal, one can be made using the high temp gasket sealant to insure nothing can back feed into the garage with say windage.. the sealant should absorb most of the heat that comes in contact with the vent housing but be sure to check with meter..

      This method should alleviate that problem since we are using a solid pipe to extend out the plastic porthole for the exhaust.

If something should happen to the generator and you have modified it in some way then this would void that warranty.

      Hey Aldo, I've been toying around with the notion of selling just the flange as many have asked the same question of me. Problem is pricing, labor, and shipping cost. Since the part is made of galvin steel it has some weight to it, so standered shipping cost add about $10-15 alone. Then there's time vs. money. To make one or two here and there it's really not worth it and most usually back out once they here the cost for a custom made hand Crafted part that no else makes.
      People have gotten so use to buying things popped out by a machine that they tend to frown upon the pricing from those who make something from scratch and by hand.
      I have looked into getting the flange Aluminum CnC'd made which is more light weight with regards to shipping but that requires a hefty upfront investment and without a group buy (kick starter) of say, at least, 25 units this idea can't move forward. It's really only the flange that is needed. The rest can be bought online.

    Nobody addresses the problem caused by changing the back pressure in the engine. You have no idea of intake pressure before you start. Increasing the exhaust length increases pressure but decreases engine efficiency. If you checked, you'd probably see rpm s decrease as well as torgue because the generator is engineered to run at low rpm. High RPM helps reduce the back pressure. I'd say you would have to consult the manufacturer about this. When you do that, they will say-don't mess with their shit-don't extend the exhaust because you can't use our generator in ANY kind of enclosed space. If you don't believe us-ask our lawyers.

      He has increased the diameter of the exhaust pipe and as long as he doesn’t have any tight bends in that 1 1/4 flex exhaust pipe he hasn’t increased the back-pressure to that engine. The exhaust is 3/4 coming out of that generator and he installed 1 1/4 pipe.

      Hey MEO, Actually I've had quite a few people ask me to make a kit for the 2000 watt HF Gen/inverter and the answer is I can't since I don't have one to make a JIG for the flange setup. I don't know if HF is using the same exhaust muffler as the 3500 watt big brother. There are to many variables including mounting whole locations, exhaust pipe size, location of the exhaust exit hole with regards to the plastic covering.. If you don't get the extension pipe exactly dead center then it could touch the plastic covering and cause melting.
      If I had a loaner Generator for a week or two I could make kits for sale.

      Yes, it would be wise to put up a carbon monoxide sensor to alert you if there is a leak. This is also required by law to have in homes in most states. If performing this mod for the use in an RV i highly suggest you put one in as well. Better safe than sorry

      Brother, if you can't figure out how to secure fasteners in place and keep them from backing out do to vibration then DIY and fabrication in general, is not for you.. let me educate you a bit before you attempt this and kill yourself.. it's called loctite and comes in two colors, blue and red.. one holds stronger then the other buuuut I'll let you do your own homework from here..
