I have done many conversions to natural gas with kits. The main issue with the conversion is jumping between lpg and natural gas fuels, you have to adjust the air/fuel mixture it's small amount but makes a difference. If you go back to gasoline no need to adjust a air/fuel mixture. Now the fun part, if you want your generator to run at full load on natural gas or lpg you must adjust the rpm's. "BUT" big BUT if you swap back to another fuel the rpm's will be off and over run your generator. That's why I think tri fuels from the factory have a lower rating on lpg and natural gas, not having to adjust rpms finding a happy point between all 3. I think that unit is worth money especially if it has low THD. Great work Gavin!
@@AdamFeldman42 No guide that I know of, engines and models adjust different. You can google or youtube your generator for how to "adjust RPM's, you will also need a small engine tachometer. Do this at your own risk, first time I tried fudge it up. Loosen governor in place of just making a small bend to the spring holder. Most of the time it's only about 300 to 600 rpm's but it does make a difference.
First of all Natural Gas burns cooler than propane, that is why they have a different orifice and spring load on the regulator, second it is impossible to get a standardized fuel pressure system in the US, some areas are better than others and others areas are nearly impossible to achieve, this why I think most manufactures want to use gasoline and propane. This is why you need to know the WC rate of your natural gas for the region, we have 8" WC so we are good, some areas around us how High Pressure but you are not allowed to tap off those lines, big problems doing that.
Genmax is looking so good, most gennys can't reach their power rating yet Genmax goes above and beyond again and again. No wonder you want to be a dealer for them. You get what you pay for in generators. Very nice, Thanks!!!
Yessir not to mention all the research and development that goes into producing GenMax brand. More options and fully loaded Generators Great warranty and Customer Service.
Great video, Amps ratings for the GM10500iEt Tri-Fuel Inverter Generator, on Gasoline 120v 70.8 Amps 240v 35.4 Amps, on Propane 120v 66.7 Amps 240v 33.3 Amps, on Natural Gas 120v 56.7 Amps 240v 28.3 Amps.
It looks like it can run that heater at 7200 watts without overloading even when the generator only rated at 6800 watts on natural gas very impressive thanks for the review.
Really nice 👍 buddy. That generator is a monster. I don’t farsee not being able to run the entire house on gas or propane. Did you have a video on that watchdog adapter? Or a link I like to view more information about it. Thank Gavin. Keep up the excellent job 👍
I wanted one of these trifuel Genmax really bad, but could not justify the price. Plus I read several review that the build quality was not always that good. Instead I went with an open frame Westinghouse 12500. You get 500 more watts on natural gas than the Gemax. I know it will be a little louder, but I can get past that.
The fact that GenMax includes is interesting to me a 1/2" hose is included when I was under the impression that you needed a 3/4" hose with full 3/4" connections for NG gensets.
Hi Gavin... thanks so much for sharing these videos. One question... when running your heaters to create a load, shouldn't one use the bonding plug to create a bonded neutral?
Great video. What size NG hose is that? At these power levels, you want a 3/4" NG hose, because you will be needing upwards of 130,000 BTU/Hr. A 25' 1/2 inch hose can only deliver about 95,000 BTU/Hr, but a 25' 3/4" hose can deliver about 150,000 BTU/Hr. Using a too small hose is like breathing through a straw.
95,000 BTU is more than enough for two of these generators after one of my customers had someone calculate the BTUs ratings came up with 35,000 per unit.
My friend.... don't be so sure! 35,000 BTU is about what my 3 burner Webber gas grill needs! And it has no motor. You might want to look at the manual for that Genmax. My 8,000 Tri fuel Champion generator (100416) is smaller, and according to the manual on page 33-34, Champion says undersizing the NG supply is the #1 reason for under performance. Champion 8,000 watt Tri fuel needs a maximum NG flow rate of 135,000 BTU/Hr at 5-7" of WC. See P.34 of the manual. (link below). And that is to just generate 7,000 watts on NG! So, unless Genmax has somehow figured out how to extract 3X the BTU per CU/FT of NG than all others, your Genmax must need at least as much - if not more - BTUs of NG to run at a higher power! I tried to find a Genmax manual online to see what the manual says, but was unsuccessful. The Champion manual can be found here: www.championpowerequipment.com/wp-content/uploads/2022/07/100416-om-english-21APR2800000-Y2203160048.pdf
This is awesome! What pressure is your natural gas meter regulator? Some homes are 7” WC (inches of water column), and others are higher. What does the generator require for BTU/hr?
The specs in the video description say it uses 3.27 cubic meters of NG per hour, at 100% load. That’s about 115.5 cubic feet per hour, or 120,000 BTU/hr.
thanks for the show Gavin. So, if it’s running on natural gas, will carbon monoxide be a concern or not? You mentioned it smelled like a stove, so I thought maybe CO is not a concern, but I’d like to confirm it with the expert. Thanks again.
Did you just tap into existing gas line? I want to do this! I have a stove with gas line that backs to exterior brick wall right below electrical box. I think i can t in there. Most installations i see them going from gas meter. My gas meter is on the opposite side of house from electrical box. 😢
I was looking at that one but unfortunately my gas meter is at the front of my house and I run mine on propane in my detach garage with the big door half open and Back feed through the garage, works great but doing it that way I can not use a interlock but I made signs for me to remember to shut the main off first.
Do you know if this is a "floating neutral" generator or a "bonded neutral" generator. I need a floating neutral to interface with my Generlink switch, and my Honda EU6500 is that. But it will cost $1000 Canadian to convert to natural gas so better to buy a dedicated tri fuel unit as long as it is a floating neutral generator
@@GeneratorReviews SUPERB !! Now I have to figure out how to get this in Canada to replace my Honda EU6500 and have a home backup that works on natural gas. Unfortunately, the TMG Industrial generator which looks to be almost an exact copy of the Genmax, is "bonded neutral" so can't be used. Also converting the Honda to natural gas through PMG Technologies will cost me almost $1000 for parts and this makes no sense when I go to resell the unit. So, at this point, I'm in limbo................
Genmax definitely proving itself to be a quality product.... anxious to see the max 240v amp output on gas.... see what it can sustain without tripping the breaker.... it claims 35 amps on 240.... Would like to see how the load cell shows power divided when two of the big dogs are in parallel (9k or 10.5k) .does one max out & the other pick up the excess, or does it split the load evenly? .. the plug is rated 50 amps... so what happens once it reaches its max 50amp load.... if two big ones are paralleled, theoretically capable of over 60amps even with the 9k... do you simply get limited to 50amps?
@GeneratorReviews Since this heater you said it 30amp, you used an adapter from 30 to 50 to hook this up to a 50amp surge protector, right? Also, I'm just curious, could this test be done on a 30amp outlet? Also, this heater is 220v. I thought you could not get that with a single unit without paralleling to of these
This is a really nice genny, great review Gavin. I think all generators produced today should be tri fuel. Living in Houston just went thru a power outage for 8 hrs. I have the WEN 56380i 3800-Watt Inverter Generator that I converted to tri fuel. Was able to run lights, router/modem, TVs, refrigerator, and 8000btu portable A/C. But it has it limits and would like more wattage. It makes sense to run on NG endless fuel supply.
Man wish duromax made a trifuel inverter. Is there anything I need to do to hook it up to my interlock. My duromax 9000ih I had to remove the bonded neutral
Gavin, can you please test the smallest natural gas (trifuel) generator out there that can connect in parallel? I think that'd be the most useful generator for average homeowner.
@@GeneratorReviews it looks like the champion 8125/6500w, the Firman 4000/5000w, and the sportsman 4000/3500w are the cheapest 3 available from big box stores. I don't know if they have invertors or can parallel. I'm looking at the cheapest buy in where I can expand later.
Could this run a 3.5 ton central AC unit, without installing a soft start on my A/C? My ac pulls 5kW when running I think. So that leaves about 2kW headroom on natural gas. If not on natural gas, what if I ran it on propane instead, could it handle it?
@GeneratorReviews thanks Gavin I'm going to keep saving in wait until it comes out a little big for my home but buy once cry once I like it because of the natural gas built-in feature great video thank you
Damn...can't wait until this unit comes to Canada. It will replace my Honda EU6500 that I was going to convert to natural gas at another $1000. I could sell the Honda and buy one of these and have money left in my pocket....

Sure looks like a winner to me. Nice to see it working off 1/2" NG line but do be aware there is some ymmv here based on your local line pressure.
Thanks Gavin! You are killing it with all the angles! I can't wait to get one of these Trifuel + Inverter gennys.
Trifuel is where its at!! This is an awesome generator. Awesome reviews. Encourage your contacts at Genmax to make a tri-fuel version of the 7250!!!!
I have spoken to them about that and I will keep reaching out because we need a tri fuel 7k and 9k inverter also.
It looks like it can run that heater at 7200 watts without overloading even when the generator only rated at 6800 watts on natural gas very impressive thanks for the review.

That generator is a beast 😮 great video as always thanks
Always interesting information!
Did all of those fittings come with the package, or did you have to go buy any adapters or nipples?
All the fittings come in the box
That’s very impressive. 💪🏻

thanks for the show Gavin. So, if it’s running on natural gas, will carbon monoxide be a concern or not? You mentioned it smelled like a stove, so I thought maybe CO is not a concern, but I’d like to confirm it with the expert. Thanks again.
Yes, you still have to run the generator outside 10 to 15 feet away from any opening just because you’re running on natural gas that still applies.
Did you just tap into existing gas line? I want to do this! I have a stove with gas line that backs to exterior brick wall right below electrical box. I think i can t in there. Most installations i see them going from gas meter. My gas meter is on the opposite side of house from electrical box. 😢
Yes that’s all you need to run this generator
I wonder what the rated amb temp is for? Says 77 degrees. I wonder if that's for sustained full load. Because that won't cut it anywhere in the south.
I was looking at that one but unfortunately my gas meter is at the front of my house and I run mine on propane in my detach garage with the big door half open and Back feed through the garage, works great but doing it that way I can not use a interlock but I made signs for me to remember to shut the main off first.
How long is the hose? Great video
It comes with a 25ft hose

If I run on natural gas for 4 hrs straight what's that going to do to my gas bill? Compared to propane at 5.00 per gal
