And here I am, after Beryl.

My power is still out, and I need to connect my dual fuel westinghouse 12500 to natural gas. I am very confused with the regulator stuff. Do I have to disconnect the one for propane ? To be able to connect to the natural gas one? Is there any link/model number for a natural gas regulator? Do we find them in a Lowe's or Home Depot around the Houston area?

@@redb2153 Hi, if the stock propane regulator is adjustable, some are but not many, then you can open the adjustment screw a few turns, and that should be fine, if it is not adjustable, you have to buy that special low pressure regulator do not put a barbecue regulator on it. That would be dangerous because the gas will continue to flow gas even if the generator is off, I believe you can get a Nash regulator on Amazon eBay or directly from Nash

Hi! Did you replace the propane inlet on the generator with a different type or found an adapter that fits?

Thank you for sharing your setup Jerry. So, did you connect the propane regulator that came with the generator to your NG metal pipe using a quick connect? Also, did you have a chance to test the maximum wattage that the generator can handle? I assume the regulator that came with the generator doesn't have a screw that throttles the gas flow unlike the one that comes with 100155 kits. So, I wonder if the generator will get the right amount of NG when the black regulator that come with the generator. Thank you very much for your time in advance.

@@newsysop I used a quick connector on the Black regulator. I've only tested with my RV with everything running. The generator only spiked up to 50% load and back to 25%. It Didn't run any different than it did on gas or propane. I'm sure there will be some loss in power but for my use it's irrelevant. The propane regulator nearest the bottle will have an orifice to reduce flow. The black regulator doesn't have any restriction so it has plenty enough flow.

Can you detail the parts used, what do you mean between the propane regular and the black regulator?

@@Oblivionsurveyor For natural gas you will only need the large black regulator. Natural gas is low pressure so you won't need the smaller silver regulator that is near the propane connector. I don't have a detail list made up as most of the quick connectors I already had laying around.

@@JerryHawk250 So the two regulators are attached to each other and the silver one is the one with the plastic QCC propane connect? So that would have to be removed for proper NG operation?

Thank you for getting back to my question so quickly. If I understand correctly, I should be able to attach the natural gas low pressure regulator at the meter, change the propane inlet fitting that came with the generator to a size to accomodate the natural gas hose fitting and I should be good to go.

Thanks for sharing your knowledge! As best I can tell from your video, this conversion should work for any home-use size propane generator, correct? Thanks

@@robeason9594 looking for the same answer...I have a Pulsar 4700w or so Gas/LPG and want to convert it to NG...but I'm worried about buying the wrong parts

@@GoldshackGarage Adam if it’s set up for propane you just need a low pressure regulator for the natural gas, you need to get one that has the Adjustment to set the flow of gas, There about $100.00 plus the BBQ hose, there’s nothing to adjust on the generator if it’s already set up for propane, natural gas will give you a bit less power but unless you’re using the generator to the maximum you should be fine

@@emilyc5309 I’m not familiar with that model number. If you’re propane setup has 2 regulators together on it a small one high pressure first one closest to the propane bottle and a bigger one low pressure negative pressure that is connected to the small regulator you should be fine to install just a new negative pressure regulator there about $100.00 on Amazon or eBay they have a primer button in the center. if you’re setup has only one regulator at the propane bottle it’s not going to work unless you remove the internal regulator because it’s setup for propane and natural gas needs to be adjusted deferent Hope this helps.

@@whatsaroundus Hi, we removed the factory fitting, just turn it slowly and it will come out, and then you will be left with a 1/4 pipe female fitting on the generator. You can also do it with the 3/8 male but it will stick out more and can easily be hit. Hope this helps

@@MrSaltydevildog Thanks 👍🏼

Yes you need the regulator, it a negative pressure regulator gas will only flow when the generator is on sucking (pulling vacuum) or if you press the primer, if you don’t use the regulator gas will keep flowing with the generator off very dangerous

Robert O. Thank you for the explanation!

Now that was an excellent question to ask Robert, and thats why I looked for his answer because I was curious, as I like to learn new things, even though I have no natural gas hookup. And I just learned today about negative pressure gas systems, never heard of that before, almost sounds like a safer system then positive pressure, would you agree?

If it’s a dual fuel generator, then it already has a regulator for the propane. Adding the extra regulator seems to be an unnecessary duplication, unless there is some major difference in pressure or flow rates. Have tried it without the extra regulator to see if one already on the generator is sufficient.

@@roberto5537 Doesnt the generator already have the secondary on demand regulator? I dont understand why that one wouldnt stop the gas from flowing if it wasnt being consumed.

I believe it was a 1/4 pipe, was a long time ago Just remove it slowly and see what’s there

You can’t feed natural gas directly to the generator it will leak natural gas, Very dangerous and won’t work, You need the negative pressure regulator you see I put next to the gas meter, it’s about $100.00

@@roberto5537 Ok, thanks. I don't even have a generator yet. Thankfully, my city has it's own power and it RARELY goes out. One of these days though!!! One of these days lol Thanks for the video! ;-)

If it’s at least 3/4 pipe it should be fine, a short run +or - 5 feet of 1/2 also should work, if there’s not enough gas supply the generator will not produce the full capacity it won’t harm the generator Hope this helps, I have more videos with it running off a 3/4 line in the back yard

A 3/4" socket worked fine to remove the propane flare fitting from the front of the unit. Interesting note is that the thread feeding the carburetor on the other side of the flare fitting is only 1/4".

What kind of thread is that 1/4"? NPT or flare? Tks

The Propane regulator is on the outside regulator, it has two regulators together, I don’t know if any generator the has the regulator in it, the fuel intake is on the side of the carburetor and the adjustment are made on the low pressure regulator. Check out my Harbor Fright 3500 convention it explains it better. Or the gas only Westinghouse conversion to NG

The original is made for propane and had no adjustment Screw, and we wanted to keep the propane setup also, don’t know if it will work, just make sure it doesn’t leak when it’s not running, you will have to split the Hi and low pressure regulator. $100 for a proven safe regulator is not too much for peace of mind. even if you get a different generator you can keep the regulator. Watch my Harbor freight NG 3500 conversion it explains how it works better

I know 1/2x 16’ works but anything more I don’t know, it won’t hurt the generator but the output will be less if it doesn’t get enough fuel good luck and thanks for watching

Hi, it was over 2 years ago so I don’t really remember what exactly was the fitting, it was my nephews generator we ordered on Amazon a BBQ NG Quick connector with a 1/2 hose After we received the hose we removed the fitting from the generator and went to a local hardware store and got the fitting and adapter to make it work, The regulator just needs to be a regulator made for a generator there about $100.00 there’s regulators are special and don’t flow gas if the generator is stopped the kind doesn’t matter, I have used Nash and US Carburetor I didn’t see any difference Nash is a bit cheaper Don’t use a appliance regulator it won’t work and will allow gas to flow when the generator is not running. Hope this helps Robert

Many thanks Robert.

Hi, I couldn’t find any sold separately, It’s a 3/8 tee Tapped with fine threads on one side and a bolt that goes in and closes the path of the gas, and a locking nut to keep it from backing out , nothing special probably easy to make, you can probably use a ball valve, after adjusting remove the handle, use a 1/2 hose to supply the gas to the generator from the regulator, 3/8 is too small Good luck

Hi Larry, no Kit was installed I used the original propane intake, I didn’t like the original 3/8 fitting setup some generators have the quick connect from the factory and that’s what I wanted, this is a Option and it does not have to be done, but it makes it easy to Disconnect and change from one fuel to the other. No tools required if I’m not home my wife can easily Figure it out and there’s no way I’m doing it wrong, you can Bleed the air from the house while it’s attached to the generator I never start on gasoline and switch over to something else. The air fuel adjustment is on the Regulator not on the generator so by having two regulators one set up for propane and one for NG just attach the one you want and start. I have more videos on conversation even a IGen gas only to NG and a HF 3500 to NG. Thanks for watching

One more thing to change the original fitting to quick connect just unscrew the original fitting slowly I never opened any covers on the generator for this conversation.

@@roberto5537 Some of the bifuel generators(gas/propane) that I looked at, tended to have a ptopane regulator behind the inlet port. If I understand your post, this unit goes from the inlet port directly to the carborator on this westinghouse igen 4500. That is good to know. I have the US carb kit for my Generac XL 5500, and I could use that to deliver NG directly to this generator without buying another motor snorkel. That is good to know. Thank you....

Much appreciated!

Only if it’s before the low pressure regulator after the regulator a 1/2 if fine just keep it under 15 feet, if you’re going longer than yes 3/4 will be better, keeping in mind that it Reduce down to 1/4” before going to the carburetor

@@roberto5537 okay thank you I bought the regulator you suggested off Amazon I'll probably run at 20 ft. Thanks again

I'm not sure but I was told that everything on the house side of the gas meter is yours. You can install a cooktop, BBQ or other gas fired devices without any problems, so why not a gas fueled genset? Remove the regulator until you lose power and all they'll see is the stub.

cellpro10 if you going by the book and ask your city they will gladly take your money to inspect a 8” pipe, There not going to pressure test because the piece of pipe you installed is less than what will be required to do the test. Inspectors where I live says if it’s under 10 feet no pressure test is done just a bubble test. most people will not get a permit for a water heater and that’s requires one. if you don’t fill safe working on gas line, electrical or water pipe, call someone to help you, I just made a couple of videos because there was none out there and might help someone, I’m converting a IGen 4500 gasoline only to run also on natural gas, I will post a video it will also be connected to the house with a transfer switch

Hi, I had a big 8000 watt generator it was very loud can’t run it a night, sold it and got the predator,, I run my whole House with a Predator 3500 I have a video of that one converted to natural gas also and this one in you see in the video does the same, 3000sf house with no AC, The Westinghouse has a bit more power but the Predator will do the job, we both have 2 refrigerators and all LED lights, LED TV we run that and all the small stuff satellite TV box and routers, and one more larger appliance like washing mashing, furnace or coffee pot, and it will be at a 50 to 75% load, don’t start the generator under load, start the generator and then plug in the refrigerator, if you have a smart meter you can run the stuff you’re thinking of running and check to see how many watts it is drawing,, we back feed the electric panel with a transfer box, Only one can be on at a time, generator power or utility power But you have to make a special plug 30 amp 120 volt twist lock for RV plug on one side and short circuit the other side with a 220 30 amp plug have a jumper wire from the two sites red and black that way it will feed both sides. Hope this helps, I might do a video on that

@@roberto5537 I did see your other video of you converting the predator to natural gas. I would love to see a video how you have it wired up and it running the whole house. Thanks

It’s 3/4 pipe so yes you will need a 3/4 to 1/2 bushing or a bell adapter with a 3/4 nipple Good luck

Robert O Thanks for the quick reply, I’ve got one ordered now. Thanks again.

First, thanks to Robert O for the video. I would not have tackled this without his example. Adam, I contacted the regulator manufacturer, Impco technologies, who makes the Garretson KN regulators. Per their techincal support, the regulator is best positioned within 2 feet of the generator (so apparently it is not optimal to place the regulator at the far end of a 3/8" supply hose as Robert O has done, although his approach seems to have worked for him). Given this information, I put quick connects on both ends of my conversion (shunning having to screw in the regulator at the source each time that Robert O used). I used a 1/2" quick connect on the supply side attached to my 1/2" house stub, with a 1/2" hose feeding the 3/4" supply side of the regulator, and then between the regulator and the unit I used a 3/8" quick connect. I found the 100155 kits to have unnecessary parts and were missing a load block (I got the proper type of load block for $18 + shipping from US Carburetion). If I had it to do over again I could have saved $50 from the kit price and just bought the regulator alone on Amazon and pieced together the rest. I have no flimsy hoses, barb fittings or hose clamps in my setup -- nothing but solid flare or npt connections. My setup works great. Now I look forward to the next power outage!

@@p.andrewwill3523 Hi Andrew, Thank you for sharing your setup. Did you attach the Garretson regulator to the generator body? Also, do you mind sharing the exact model number or Amazon link of the Garrtson regulator? BTW, was the supply side of the Garrtson regulater 3/4"? Maybe a typo of 3/8"? Thank you for your time in advance.

@@newsysop Yes, the supply side of the Garretson is 3/4", not 3/8". Also, see this link for my setup and detailed parts list. drive.google.com/drive/folders/1_JaOwkugJYwtpVpv5rRHaOwAV5cwgKd1?usp=sharing

Devin O'Dow nothing was done to the generator no adjustments, except the quick connection and that is optional, you can keep it stock and will work fine. I think 12 feet away is max for the 3/8 line Hope this helps

@@roberto5537 Robert, big fan here, I set up my Predator 3500 from your video about that genset. Just for info only, I'm running 18' of 3/8" air hose from the regulator on the natural gas meter plumbing and have 3KW full power. Your original tip about the Parker brand quick connect fittings is probably the reason. I discovered that those fittings are used on pressure washer lines, therefore the lack of internal valving and obstructions. They are available for about 1/2 the Parker price from Lowe's and Home Depot and seem to work fine. I first tried regular air line quick fittings, but dropped about 20% in power due to the restricted flow. My propane hookup also gets the same 3KW output @ 4.5 turns out on the Load Block. Natural gas is at 6 turns for my gear. Thanks again, keep up the amazing work, you've saved us a lot of experimenting and frustration.

cellpro10 thanks for the information, I’m waiting on some parts for a igen4500 gas only to convert to NG and the meter is 15’ away so I wasn’t sure if it would work so I got a 1/2 hose, now I know the 3/8 will work, i don’t see a loss of power with these kits. Thanks again

Natural gas is about 1/3 the price of gasoline or propane it doesn’t have any more power maybe a bit less, endless supply and price was the main reason, We lost power 2 times for 3 day in one month used over $120 of propane the first time every one was getting per filled propane for cooking on the BBQ, couldn’t refill your bottles because gas stations had no power and couldn’t get gasoline either, had to drive 20 miles and long lines. with Natural Gas you don’t have to have 3 or 4 full bottles or propane around just in case it happens again, never heard of the natural gas ever been turned off in stormy weather. Second time 3 days we used NG no stress on running out and running 24/7, on propane we turn off at night

@@roberto5537 I've had some neighbors lose natural gas due to uprooted trees! That's why I think it's great to see a unit with so many options.

@claude Thanks, but the pressure is good, I just had a new gas pack installed and when they put the tap for the generator in at the same time, they pressure checked all the outlets.

I think the problem is mostly solved now. I removed the quick disconnects and extension hose and replaced it with 3/8 hose and flare fittings on each end. Once I did that, I was able to run the genny up to just past half load and it held okay. If I try to go to 3000 watts, it drops voltage and eventually goes into overload shutdown. A test run today with the load block screw almost all the way out and the new flared 8' line, it powered the house (no AC or Heat) The goal was to be able to keep both refrigerators going along with modems, lights, and one portable AC unit "just in case" It handled those just fine. So apparently the problem was a gas restriction in the disconnects and extension.

@claude Yeah, I knew it would be less power on NG, but I was a bit surprised that it was that much different. The test run shows it will do what I needed it to do though with the lockout on the house. hopefully the hurricanes all pass NC and I'll never have to depend on it ;-) Never did hear back from Nash after I called and he asked for photos of the setup.

A 1/2 inlet gas line is small especially if it’s far away from the gas meter, and from the regulator the quick connector after the regulator can’t have any restrictions like air line fittings, it needs to be gas line quick Connector like for a BBQ or a Pressure washer, I can get 3500 continuous watts from the Igen4500 and 3000 watts from HF predator on NG, with a 3/4 gas supply line and a 3/8 8ft or 1/2 12ft from the regulator to the generator. I also have a Video on a Igen4500 gas only convention to NG with load test Hope this helps, thanks for watching

@@roberto5537 The half inch line comes off a 3/4” line about six inches from the meter. The extension was a gas line for a propane grill with the quick disconnects that came with it.

Hi, 3/8 hose is only good for about 8 feet, use the 1/2 BBQ hose only get The length that you need and make sure you use the correct quick connect, don’t use air hose quick connect, the voltage will drop just as long your at 110 or over volts you should be good.
