- T07573 is Costco model number, T07571 is the retail model number. Though NG has less output than Propane or Gasoline; NG is much more convenient and unlimited. No need to run out to refill propane tanks or gasoline cans. No need to worry about gas gumming up the carb. NG is always available except for extreme mother nature's disasters ie earth quake.
A lot of people have trouble getting NG to start on their generators. Much has to do with understanding how the choke works with your generator when using natural gas. Some experimentation needed to get the feel. First time I used NG, I had a hard time getting the generator to run until I realized: use the choke to purge the air and then back off the choke to get the generator running. Unlike gasoline, do not need the choke for running.

Part-1 Unboxing : • Firman Tri Fuel Genera... - Навчання та стиль
Fantastic job explaining everything! I’m just now unboxing mine after having it for 3 years. Surprisingly, the battery shows 12.77 volts. I’m going to put it on a charger anyway. Thanks for the advice.
I have a 4-ton (46,000 BTU) A/C unit. Installed is a Micro-Air EasyStart 368 (4-ton) Soft Starter on the outside unit. My A/C unit now uses has a Start Peak of 33 to 36 Amps. This allows the A/C compressor to start and run when using the generator.
I also installed a soft start on my A/C too. Works great. I did make sure I used the proper gage of wire running from my gen inlet plug for a 50 Amp cord and connector and big power cable. Wouldn't take a chance wiring for a 30 Amp setup. My entire home runs without problems even with Natural Gas hookup. All LED's in lighting fixtures, natural gas stove, water heater, furnace and dryer. I bought 2 Generators so I can swap them every day to give them a break and let me change the oil. I live in Barataria, La, south of New Orleans and when we lose power, sometimes it's for weeks. With 90 to 100 degree days you have to be able to run your A/C unit, dragging out window units just don't cut it. One of my clients at work is the repair guy for G-----c backup systems. he told me stay as far away from them as possible. After the time I spent two hours waiting in a line for gasoline for my old generator only to be told at the pump they were stopping sales for the day I had to get a tri fuel generator system. Best money I've spent. Soft Start is the way to go like you said.
Great job explaining everything! Purchased mine a while ago and this one makes me feel a lot more comfortable and confident in using it. Thanks !
I ended up installing a MB Sturgis Propane Elbow Adapter at the generator 3/8" POL fitting. It is a 3/8" Female Flare Swivel x 3/8" Male Flare (Item # 204163) that I purchased from etrailer. Then I installed the 3/8" Female x 1/2" Male brass adapter there. Now it is easy to store the 1/2" NG hose on top of the tank while still being connected to the generator. I also helps avoid tripping over it.
Good idea, the 24 footer barely fits on the hose storage strap. Just have to cap the open end to keep critters out. Any issues with the swivel eventually leaking?
@@rossishima I have not had any problem with leaking as long as the elbow adapter is tightened with a wrench. It is not suppose to swivel when installed. Mine is pointing 45 degrees downward to the left.
I have the T07571 tri-fuel. The 1/2" hose I bought had a 3/8" Female by 1/2" Male brass adapter to connect to the generator. It was too long (deep) on the female end and I had to sand it down so the flange in the adapter would seal against the LP gas fitting on the generator. The other end is a 1/2" male quick disconnect fitting which easily connects to the female fitting attached at the gas valve. Check the connections with soapy water.
Trying to line up the cable plug with the inlet at night? Take a marker or white-out and make a line on the plug & socket to line up the two before you twist it. Keep battery charged. Install emergency lights that come on when power goes out. Install them where you set up the generator and at the panel. Have an extra spark plug. Maintenance is easier when using natural gas to power the generator.
Good thoughts. Why I pointed out the Shinestar, because it works with the Firman. Some other brands people had issues with regarding quality, leaks, etc. The solar generator works perfect, I just go out every few weeks and plug in the float charger. Within a couple hours its on float mode so I disconnect the solar generator and bring it back into the house for other uses. The generator pulls around 7 watts from the solar generator. The lead acid battery holds it charge pretty good.
At 25 feet, this generator will run with a 3/8”
Do not use Teflon tape or pipe sealant on any flare ends because you will not obtain a leak-free seal. Keep flare end of fitting free of grease, oil and thread sealant. Use a wrench only on the hex surfaces of the fittings. Using Teflon tape on flared fittings can prevent the metal to metal seal from working.
As a rule of thumb you are correct; but many plumbers still use teflon tape/dope on threads. I pointed out to leave exposed thread so no tape will go between the two mating surfaces. The seal is from the metal to metal contact and not the threads. The tape does not hinder a seal, a leak is because the connection is not tighten enough or if it is over tighten causing nut deformation. If the connection is torqued correctly, there will be no leaks; tape or no tape. Some argue the lubricating nature of the teflon tape may lead to overtighen. Just tighten til snug and check for leaks.
For a permant install, no need for the tape. For a temporary/short duration usage install like a generator, the tape probably used as more as anti seize lubricating the threads for easier on/off the hose. Also, the generator is outdoors in open air. Technically the fitting and hose should be a one time use. Replacing the hose everytime you hook up the generator is too costly. Just inspect the flare mating parts for any damage or scratches when removing the hose. Regardless, always check for leaks during install and periodically while running because of vibrations. I called Firman and they said ok to use the tape on the flare fitting.
I have this model. You don’t need any tape. Just a wrench
Thank you for the insight...we are looking at different generators and I'm very new to the whole back-up power solution for power outages. I came across this Firman at Costco and thought it would me our needs. Mainly concerned about our 3 fridges/1 freezer and a few other items like TV/space heater. Looks like this T07573 will do the trick and we can also take it with us on camping trips in our trailer. I think I found your additional items. Perhaps if you made some affiliate links with all the products you purchased/used would be helpful. I think I found them all. Working on completing my research but your video was a great help. Cheers
I try not to apply links to products as I am not sponsered by anyone, though I will provide the manufacturer. Everything comes out of my pocket so my experience with a product will be the same as yours. I do extensive research before parting my money on a product so misses on my end are limited and most of my reviews end up being positive. For the price at Costco, similar items at other big box stores are more expensive and not being tri-fuel. As for camping, though this generator is not super loud at 70+db at 20feet, at a public campsite it still will be loud. I will look into a solar generator with a portable folding solar panel. Latest generations have plenty of power and will be silent. You will be happy with the Firman.
Calculating the wattages based on the soft start Amps @rwstarke mentioned, 4 ton AC start wattage needs ~8kw alone, which is way passing the NG limit, near the LPS limit. I have a 3 ton AC, wondering with NG can I use this generator. Looking forward to watching your @rossishima next video and seeing if your AC can start with NG!
Install a Micro Air Easy Start. My 3 ton unit works flawlessly and I have a natural gas line ran to my Gen. I have a 50 Amp hookup from my generator to my house. Does not even bog my Gen when A/C kicks in.
Great video. Thanks so much! Btw how long is your gas line?
24ft
I never used that teflon tape on mine and I use natural gas too. No leaks. Not sure if it is really necessary. I disconnect my hose after each use.
The tape is not necessary for a tapered gas fitting, but it is provided more or less to make it easier to tighten and remove the fitting than to prevent leaks.
Did you put the interlock kit at all?
Not yet, I purchased the interlock and 30A inlet box.
In houston, i accident found in Facebook a licensed electric. He installed 50amp and outside outlet box. with parts $350. Last year 2023. I have same generator bought at Costco too. run natural gas. Same setup with you. Power whole house, Just use portable AC for emergency when power out. Not central AC. Happy
@@phuctran2396 Gota bargain in getting a licensed electrician for that price. Parts alone is around $100. Glad you are happy. I will be running window a/c also as on ng, this probably would not have enough for a central a/c even with soft start.
can this same line be used for a grill?
Yes, it is a regular ng gas line; not a specialty line. As long as it is a standard grill it should work, if not, you will need adapter fitting.
@@rossishima yes i have a standard Sams Club grill currently on propane, but i would like to do the added gas line to use a generator on natural gas in case of emergency and when not; use it for grilling! thanks
@@moctezumacuauhtemoc8470 Ok. You have to convert your propane gas grill to ng. They have kits for this. mainly swapping out the fuel jets.
Having trouble powering on my AC
Window or central? If central, you are going to need an ez start or soft start attached to the outdoor unit. It slowly ramps up the power so as to not overload the generator.
Oil is inexpensive. I drained it after 1 hour of running.
